My Number Card When Moving Abroad: Updated 2024–2026 Rules

Since 27 May 2024, Japanese nationals can keep using their My Number Card (Kojin Bango Kaado 個人番号カード) after moving abroad, provided they complete a continued-use procedure at city hall no later than the day before their scheduled departure.¹² Foreign residents are in a different position: their card expires when they move abroad and must be returned to the municipality.³ This guide covers the legal basis, the counter procedure, each electronic certificate, embassy issuance and renewal, and the 2026 online application system; for the overall departure sequence, see the master relocation framework.

The Historical Context: Pre-2024 Invalidation vs. The New Legal Regime

The rules changed fundamentally in May 2024, so older advice and many English web pages no longer match what happens at the counter.

Before 27 May 2024: Deregistration Meant Card Invalidation

Under the old regime, the card was tied to your resident record (Juminhyo 住民票). Filing the overseas moving-out notification (Kaigai Tenshutsu-todoke 海外転出届) deleted that record, the card lapsed, and the signature certificate was revoked along with it.⁴ The Digital Agency describes the 2024 change as meaning the card “will no longer expire” when you relocate or study abroad.¹

What Changed on 27 May 2024 and the Legal Basis

27 May 2024 is the date the overseas-use rules took effect, not the date they were enacted. On 9 April 2024 the Cabinet decided a cabinet order setting that effective date for provisions of three laws: the 2019 Digital Procedures Act amendments (令和元年デジタル手続法), the 2021 Digital Society Formation Act (令和3年デジタル社会形成整備法) and the 2023 My Number Act amendment law (令和5年マイナンバー法等改正法).¹

The core overseas provisions date from 2019 (Act No. 16 of 2019, promulgated 31 May 2019), with a clause allowing up to five years before a cabinet order switched them on.⁴ That Act amended three statutes at once:⁴

Statute	What the 2019 amendment did for people moving abroad
Basic Resident Registration Act (住民基本台帳法, Act No. 81 of 1967)	Added date of birth, sex and resident record code to the Koseki no Fuhyo (戸籍の附票) and allowed its identity data to be shared via J-LIS for overseas transferees
Public Personal Authentication Act (JPKI Act, 公的個人認証法, Act No. 153 of 2002)	Allowed overseas transferees to obtain both electronic certificates through the municipality holding their Fuhyo; certificates issued between the move-out notification and the scheduled departure date are not recorded as revoked when the resident record is deleted (Arts. 12 and 31, per the MIC notice of 31 May 2019)
My Number Act (番号法, Act No. 27 of 2013)	Let the Fuhyo municipality issue cards to overseas transferees and created the continued-use procedure, triggered by presenting the card with the overseas move-out notification

The key shift is the identity base. After you leave, your card’s name, date of birth and sex follow the Koseki no Fuhyo, a supplementary record attached to your family register that tracks your address history, rather than the deleted Juminhyo.² Only Japanese nationals have a family register and therefore a Fuhyo, and that single fact explains the different outcomes for citizens and foreign residents.

Who Is Eligible: Nationality, Departure Date, and the Honseki Municipality

Continued use is open to Japanese nationals holding a valid card who file an overseas move-out notification.²⁵ Japanese nationals already abroad can obtain a new card if they moved abroad on or after 5 October 2015 and do not currently hold one.²⁶

Suginami City lists who cannot apply for a new card from abroad:⁷

People who currently have a resident record in Japan.
People born abroad who have never had a resident record in Japan.
People who left Japan before 5 October 2015 and have had no resident record since.
People without Japanese nationality, explicitly including former Japanese nationals, Special Permanent Residents and mid-to-long-term residents.

After departure, your competent office changes. Card changes, PIN changes and certificate issuance are handled by the municipality that keeps your Koseki no Fuhyo, in practice the municipality of your registered domicile (Honseki-chi 本籍地), with embassies and consulates acting as a channel.⁸³ Note your honseki municipality’s name and contact details before you fly.

The 2026 Update: Online Applications for Overseas Cards

From 26 May 2026, applications for a card for those moving abroad moved online through a dedicated J-LIS overseas application site, separate from the domestic one (as of October 2026).⁹¹⁰ J-LIS stopped posting the paper application form at the same time, and Suginami City confirms that paper applications have ended (as of October 2026).⁹⁷

This guide does not walk through the online form. Start from the official J-LIS page on overseas use, because the application site itself asks for personal data and may change its screens.²

Japanese Citizens: Retaining Your My Number Card Overseas

This section is for Japanese passport holders. Foreign residents should skip to the foreign residents section below.

What the Card Can and Cannot Do After You Leave

After the continued-use procedure, your card’s address field shows “国外転出 ○年×月△日” (moved abroad, with the scheduled date), and the address record on the chip is updated.² Inagi City’s English page renders the annotation as “Moving Abroad YYYY/MM/DD (Scheduled Move Date)”.¹¹

What it remains useful for: the card still identifies you to Japanese administrations and works for online services that rely on its electronic certificates.¹²

What it does not do: the card does not prove that you live in Japan, and it does not replace your passport as a travel document.

Card Validity Period vs. Certificate Validity Period

The card and its certificates expire on different schedules.¹²

Item	Validity	Overseas renewal window
Card (issued at age 18 or over)	Until the 10th birthday after issuance¹²	From 1 year before expiry for overseas-use cards⁸
Card (issued under age 18)	Until the 5th birthday after issuance¹²	From 1 year before expiry for overseas-use cards⁸
Electronic certificates (any age)	Until the 5th birthday after issuance¹²	Via embassy or consulate, or the honseki municipality

Domestic cards can be renewed from 3 months before expiry, overseas-use cards a full year ahead; use the longer window.⁸¹²

If You Already Left Without the Continued-Use Procedure

If you left without completing continued use, your card expired on the scheduled departure date under Article 14(i) of the My Number Act Enforcement Order.²³ J-LIS lists this as one of the cases in which the card must be returned to the municipality that last held your resident record.⁸

The recovery path is a new application for a card for those moving abroad, made online since 26 May 2026 (as of October 2026); see the embassy and consular services section below.²¹⁰

Pre-Departure City Hall Counter Procedure for Citizens (Card Modification)

This section covers only the card-specific steps. The moving-out notification itself has its own guide on the Tenshutsu-todoke.

Timing: By the Day Before Your Scheduled Departure

The national rule set by J-LIS is “by the day before the scheduled departure date” (国外転出予定日の前日まで).² Chuo City, Kashiwa City and Inagi City use the same wording.⁵¹³¹⁴ If you miss it, the card expires on the scheduled departure date.²

The Honseki Coordination Trap: Weekend and Holiday Counters

At least one municipality warns that weekend and holiday counters may not work. Inagi City explains that the procedure requires coordination with the system of your registered domicile, so on special weekend or holiday opening days it cannot be completed if the honseki municipality is closed.¹⁴ Book a weekday visit, before any long weekend that precedes your departure.

Step-by-Step at the Counter

J-LIS describes four steps that run alongside the move-out notification:²

Submit your card and the continued-use application form (個人番号カード国外継続利用申請書) when you file the overseas move-out notification.
The municipality writes “国外転出 ○年×月△日” on the card face and updates the address record on the chip.
The municipality issues the electronic certificate for overseas transferees.
The card is handed back and can be used after departure.

In practice, two decisions sit inside steps 3 and 4. Decide whether to reissue the signature certificate (it otherwise lapses on departure) and whether to renew the login certificate early so that it lasts longer abroad.⁵¹³ Before you leave the counter, confirm that you remember both PINs, because resetting them from abroad is slow.⁷

Proxies are possible but municipal practice varies. Kashiwa City accepts a legal representative, a household member or a voluntary proxy, with sealed documents and, for a voluntary proxy, a power of attorney plus an inquiry and response form requested in advance.¹³ Chuo City says a voluntary proxy outside the household cannot finish the same day without that form (照会書兼回答書), and that signature certificate reissue is done by the cardholder in person.⁵

Inagi City asks proxies to carry the PIN in a sealed envelope.¹⁴ Check your own municipality’s rules.

Timeline for the card-specific steps:

When	What happens	Who acts
Before departure (window varies by municipality)	Move-out filing window opens (see the Tenshutsu-todoke guide for your city’s rule)	You
A weekday before departure (no later than the day before)	Continued-use application, signature certificate reissue, optional early renewal of the login certificate	You, at the counter²⁵
Scheduled departure date	Signature certificate lapses if it was not reissued; card expires if continued use was not done	Automatic²¹³
Abroad	Certificate renewals, PIN resets and card changes via an embassy or consulate, or the honseki municipality	You, via the mission or Fuhyo municipality⁸

What Happens to Each Electronic Certificate

Departure affects your two electronic certificates differently. The legal mechanism is national: under the amended JPKI Act (Articles 12 and 31, per the MIC notice of 31 May 2019), certificates issued between filing the overseas move-out notification and the scheduled departure date are not recorded as revoked when your resident record is deleted.⁴ Municipal pages spell out the resulting split.⁵¹³

Signature certificate (Shomeiyo Denshi Shomeisho 署名用電子証明書): Chuo City and Kashiwa City state that it lapses on the scheduled departure date.⁵¹³ This certificate records your name, address, date of birth and sex, so an address change revokes it.¹⁵¹⁶ You can have it reissued up to the day before departure, and once continued use is complete it can also be issued afterwards at the honseki municipality’s counter.⁵

User authentication certificate (Riyosha Shomeiyo Denshi Shomeisho 利用者証明用電子証明書): Chuo City states that it does not lapse automatically on moving abroad.⁵ Reissuing it at the same visit extends its validity to the 5th birthday after reissue, which Chuo City recommends to avoid renewing from abroad; Kashiwa City calls this a special renewal.⁵¹³

Feature	Signature certificate (署名用電子証明書)	User authentication certificate (利用者証明用電子証明書)
PIN format	6–16 alphanumeric characters¹⁵	4 digits¹⁵
Lockout	After 5 consecutive wrong entries¹⁵⁷	After 3 consecutive wrong entries¹⁵⁷
Data it carries	Name, address, date of birth, sex¹⁵	No name or address¹⁵
Typical use	Signing submissions, such as e-Tax identity verification¹⁷	Logging in, such as Mynaportal and website or kiosk logins¹⁵
Effect of departure	Lapses on the scheduled departure date unless reissued⁵¹³	Does not lapse automatically⁵
Action before leaving	Reissue at the counter by the day before departure⁵	Optional early renewal to push expiry out by up to 5 years⁵¹³

A note on misleading English material: the Digital Agency’s private-sector FAQ says there is “no expiration of electronic certificate due to overseas transfer”.¹⁸ That answer concerns revocation codes seen by businesses checking certificates, not your signature certificate at departure.

Fees

No official source states a fee for the continued-use procedure itself, so ask your municipality when you book the visit (as of October 2026). For overseas-use card holders, J-LIS lists reissue fees of 800 yen for the card and 200 yen for the certificate where the loss or damage is the holder’s responsibility, or after a voluntary return (as of October 2026).⁸

Foreign Residents: Permanent Departure Invalidation & Return Procedures

This section is for Permanent Residents, Long-Term Residents and work visa holders.

Why Foreign Nationals Cannot Use Continued Use

The law makes the overseas exception depend on the Koseki no Fuhyo. Article 14(i) of the My Number Act Enforcement Order says a card expires when the holder moves abroad, except where the person is recorded in a Koseki no Fuhyo and the municipality has taken the continued-use measures under Article 17 of the My Number Act.³ Foreign nationals have no family register and so no Fuhyo, which means the exception cannot apply.

Inagi City confirms that “Foreign residents cannot complete the procedure for continued use from abroad,” and J-LIS frames eligibility as applying to Japanese nationals.¹⁴²

Returning the Card (Henno) at the Move-Out Counter

Returning the card is a legal duty, not a courtesy. Under Article 15(3) of the Enforcement Order, a holder whose card expired on moving abroad must return it without delay (遅滞なく), with a written statement of the reason, to the municipality that last recorded their resident record.³ The municipality must then destroy returned cards (Article 17).³

In practice, you hand it over when you file the move-out notification. Inagi City asks foreign residents to return the card at the same time as submitting the notification.¹⁴ Your 12-digit My Number itself is not changed by moving abroad, and J-LIS notes that the number cannot be changed on request.¹⁹⁸

Leaving Temporarily on a Re-entry Permit or Special Re-entry

The trigger for expiry is moving abroad, meaning the deletion of your resident record by an overseas move.³ A foreign resident who leaves temporarily without filing a move-out notification keeps the resident record, so Article 14(i) does not apply.³

Filing a move-out notification while holding a re-entry permit still ends the card’s function. The Immigration Services Agency notes that a re-entry permit holder who files an overseas move-out notification, leaves and re-enters within the permit period finds that the card’s My Number function has lost effect (as of October 2026).²⁰ For re-entry permits, Special Re-entry and the risk of losing Permanent Residence if you stay out beyond the permit window, see the guide on Japanese citizens vs. foreign residents departure rules.

Residence Card vs. My Number Card at the Airport (and the 2026 Combined Card)

Two cards, two different offices. On permanent departure, the residence card (Zairyu Kaado 在留カード) is dealt with by immigration at the port of departure, as explained in the master relocation framework, while the My Number Card goes back to city hall.¹⁴

The Specified Residence Card (Tokutei Zairyu Kaado 特定在留カード), which combines a residence card and a My Number card, began operating on 14 June 2026, with regional immigration bureaus accepting applications from 15 June 2026 (as of October 2026).²⁰ Getting one is optional, holders may keep two separate cards, and the first issuance on or after 14 June 2026 is generally free (as of October 2026).²⁰ Its My Number function lasts only until the period of stay expires and must be updated at the municipality beforehand (as of October 2026).²⁰

If you hold the combined Specified Residence Card, confirm the departure procedure with the Immigration Services Agency and your city hall.

Point	Japanese nationals	Foreign residents
Can the card stay valid after moving abroad?	Yes, with the continued-use procedure²	No; it expires on moving abroad³
Identity base after departure	Koseki no Fuhyo²	None (no family register)
Deadline	Day before scheduled departure²	Return without delay³
What to do at the counter	Continued-use application and certificate decisions²	Return the card¹⁴
Electronic certificates	Signature lapses unless reissued; login continues⁵	End with the card
New card from abroad	Possible if moved abroad on or after 5 October 2015²⁷	Not available⁷

Overseas Digital Certificates: Utilizing Mynaportal and e-Tax from Abroad

This section covers certificate mechanics only. Non-resident filing duties and the tax agent (Nohzei Kanrinin 納税管理人) are covered in the guide on appointing a tax agent.

Which Certificate Each Service Needs

Mynaportal logins use the user authentication certificate, the one that carries no name or address.¹⁵ e-Tax identity verification with the card uses the signature certificate and its 6–16 character password.¹⁷

The practical consequence: a citizen who skipped the signature certificate reissue at departure can still log in to Mynaportal but cannot verify identity for e-Tax with the card. The fix is to have the signature certificate issued through the honseki municipality, which requires the physical card to reach it.⁵⁸

Card Readers, NFC Smartphones, and Smartphone Certificates Abroad

You need an NFC-capable smartphone or a card reader to use the card’s certificates online. The Digital Agency’s smartphone certificate service started on Android in May 2023 and on iPhone on 24 June 2025 (as of October 2026).²¹

Smartphone certificates appear to be available to overseas card holders, since J-LIS explains how to revoke one if you lose the phone abroad (as of October 2026).² After your card is switched to overseas use, check in the app whether you need to register the smartphone certificate again, and confirm with J-LIS.

e-Tax ID/Password Method Being Phased Out

The card is becoming the main route into e-Tax. The National Tax Agency stopped issuing new IDs and passwords for the ID/password method on 1 October 2025, describing the method as a temporary measure until My Number Cards spread; existing registrants may keep using it (as of October 2026).²² The e-Tax FAQ adds that the method is scheduled to become unusable from returns for tax year 2027 (令和9年分) (as of October 2026).²³

For overseas filers, the signature certificate decision at departure therefore matters more.

Renewing Certificates While Overseas

Certificates expire on the 5th birthday after issuance, so a long assignment can easily outlast them.¹² Inagi City, for example, accepts issuance or renewal applications from overseas card holders whose certificate has expired or has less than one year left.²⁴

Renewal abroad means sending the physical card. When a card is sent through a consul to the Fuhyo municipality for certificate issuance or a PIN reset, it expires if it is not collected within 90 days (Enforcement Order Art. 14(x); ministerial order Art. 30-2(2)).³²⁵ This 90-day limit applies to these consular submissions only, and it is one more reason to renew early at the departure counter.⁵¹³

Embassy and Consular Services for My Number Renewal

This section is for Japanese nationals already abroad.

Applying for a Card from Abroad (Online Since 26 May 2026)

Eligibility is as set out above: Japanese nationality and a move abroad on or after 5 October 2015.²⁷ Applications go through the J-LIS overseas application site, and issuance takes roughly 2 months, longer depending on postal conditions (as of October 2026).⁶¹⁰

You choose the pickup location when you apply: your honseki municipality, another municipality in Japan, or an embassy or consulate.⁶ You are notified by email or phone when the card is ready.⁶

Collecting the Card: Identity Documents and Deadlines

Pickup is in person only; J-LIS states that cards cannot be handed to a proxy.⁶ Applicants under 15 must be accompanied by a legal representative (as of October 2026).⁶

Pickup place	Documents to bring
Embassy or consulate	Valid passport (as of October 2026)⁶
Municipal office in Japan	Valid passport plus one other ID, such as a driving licence or pension book (as of October 2026)⁶

Collect the card within the period stated in your collection notice. J-LIS says only that cards not collected within a set period after notification expire and are discarded.⁸

PIN Resets, Suspension Release, and Reissue

A forgotten or locked PIN usually means the card travels. The mission sends the card to your honseki municipality and returns it, or you can handle PIN changes at the honseki municipality directly; the three PINs can also be changed via Mynaportal.⁸ Suginami City puts the time from application to issuance for a PIN reset at 2–3 months (as of October 2026).⁷

Reissue after loss: apply on the overseas application site and provide a police lost-property report or a disaster certificate.⁸ After a suspension is released, a card returned via a mission may take over a month, and the certificates must be reissued.⁸

Paying Fees from Overseas

Reissue fees are 800 yen for the card and 200 yen for the certificate where applicable (as of October 2026).⁸ The payment method is set by your honseki municipality, so check it before applying.

Lost or Stolen Card Abroad

Suspend the card immediately by calling the J-LIS line below (as of October 2026).²⁸ Afterwards, file a loss or abolition notice (紛失・廃止届) with the honseki municipality, also possible through a mission, or a suspension release notice (一時停止解除届) if the card turns up.⁸

Purpose	Number	Hours
Suspending a lost or stolen card	+81-3-6734-0170 (03-6734-0170 within Japan)²⁸	24 hours, 365 days; international call charges apply (as of October 2026)
Questions about the overseas application	+81-50-3818-1250⁷	8:00–20:00 Japan time, including weekends and holidays (as of October 2026)

Common Pitfalls & Regulatory Compliance Risks

Going to city hall on departure day or on a weekend. The deadline is the day before departure, and weekend counters may fail.²¹⁴
Assuming the signature certificate survives. It lapses on departure unless reissued, and e-Tax identity verification with the card depends on it.⁵¹³¹⁷
Forgetting PINs. Lockouts come after 3 or 5 wrong entries, and resets from abroad take 2–3 months (as of October 2026).¹⁵⁷
Foreign residents keeping the card. Return without delay is a legal duty under Enforcement Order Art. 15(3).³
Trusting outdated English pages. Pre-2024 material describes the old rules.¹⁸
Letting certificates expire mid-assignment. Plan renewals around how far you live from a consulate; overseas card renewal opens 1 year before expiry.⁸¹²
Losing the card on return to Japan. An overseas-use card expires if you do not file a moving-in notification within 14 days of entering Japan, or do not present the card to the new municipality within 90 days of that notification (Enforcement Order Art. 14(vii) and (viii)).³ J-LIS lists both as expiry cases, and Kawasaki City advises bringing the card when you file the moving-in notification.⁸¹⁹

The return-to-Japan rule deserves extra attention, because a card that expires under those items must also be returned.³ For people who moved abroad on or before 26 May 2024 and returned their card, Kawasaki City states that they can reapply after moving back to Japan, and that the new card is issued without a fee if they bring the old card when collecting it (as of October 2026).¹⁹
