Can you keep your US credit cards after moving to Japan? The address, payment & login reality

The short version. US credit cards don’t automatically close when you move to Japan — but keeping them usable runs into three walls: a US mailing address (cards are built around one), a US bank account to pay from, and the SMS 2FA that stops working when your US number dies. None is a dealbreaker on its own, but you have to solve all three before you leave, or you’ll be locked out of cards you spent years building.

I’m a Japanese national who spent four years in the US building credit from zero — and I researched all of this while planning my move back to Japan, because I want to keep living partly on US cards. If you’re moving US→Japan and want to keep your cards, we’re solving the same puzzle. Here’s what I found. Not financial advice — one person’s research.

The three walls

Cards don’t die the day you land. But to keep using them, you hit:

1. Registered address — US cards effectively assume a US address (KYC / USA PATRIOT Act).
2. Payment source — you need a US bank account to pay the bill from.
3. Login / 2FA — most issuers text a code to a US number you may be about to lose.

Wall 1: the US address

US cards and banks are built assuming you live in the US — issuers are legally required to verify a real address (KYC, under the USA PATRIOT Act). Practical options people use:

• A relative’s or friend’s US address (the classic, if someone will forward mail / be reachable)
• A mail-forwarding service — but some issuers reject P.O. boxes or known forwarder addresses
• Keeping an existing address on file and simply not changing it

Issuer behavior varies (all reported, not official): Citi and Bank of America have accepted foreign address changes for some people; Amex sometimes pushes you toward a local entity (like Amex Japan) if you go abroad; Chase has kept some accounts on a foreign address, but I couldn’t find a written policy. Honestly, this is the piece I’m least sure about for my own move — so treat address maintenance as “delay, verify per issuer,” not a guarantee.

Wall 2: a US bank to pay from

Even with the card alive, you need somewhere to pay it from. The names that come up for people abroad:

• Charles Schwab High Yield Investor Checking (popular overseas — refunds foreign ATM fees), and Fidelity Cash Management for some. Both, though, nominally require US residency, so an address change can risk closure — the same wall as the cards.
• SDFCU (State Department Federal Credit Union) — one of the few that openly accepts foreign addresses, though joining runs through an association (Americans Abroad, ~$75/year).

So the payment account and the cards share the same address problem — solve it once, for both.

Wall 3: the login lifeline (2FA)

This is the cheap one that sinks people. Most issuers send login and fraud codes by SMS to a US number. Cancel your US SIM and those codes vanish — the card is fine, but you can’t log in to pay it.

The fix is keeping one real US number alive. A low-cost US MVNO like Tello (~$5/month) keeps a real number on a major US network so 2FA texts actually arrive — set it up before you leave. I wrote the full version of this in keeping a US phone number for 2FA.

(Full disclosure: the Tello link is a referral link — you and I each get $10 in Tello credit if you sign up through it. I mention it because it’s the option I’d use.)

Which cards to keep

You don’t need to keep all of them. The pattern most people land on:

• Keep 1–2 no-annual-fee cards and put a small charge through them a few times a year, so they don’t get closed for inactivity.
• Use a “hub and spoke” setup: keep a no-fee card (e.g. Chase Freedom Unlimited) as the hub to hold points earned on a premium card (e.g. Sapphire), so you don’t lose the points if you drop the annual fee.
• Be honest about annual fees on cards you’ll barely use abroad — a premium card you can’t use much is just a yearly bill.

A note on credit scores

An unused US credit file doesn’t vanish immediately, but a card closed for inactivity — or an account you let lapse — can ding it. Keeping one or two cards lightly active is the low-effort way to keep the history alive, in case you ever need US credit again.

FAQ

Do US credit cards close automatically when I move to Japan?

No, not automatically. But keeping them usable requires solving the address, payment, and 2FA walls — and issuers vary in how they treat a foreign address.

Which cards should I keep?

Usually 1–2 no-annual-fee cards kept lightly active, with a hub card holding your points. Drop premium cards you can’t justify using from abroad.

How do I keep logging in after my US number dies?

Keep one real US number for SMS 2FA before you leave — see the full 2FA guide. A ~$5/month US MVNO like Tello is the common fix.

What about my US brokerage — same problem?
