Proof of address

Proof of address is the document a card issuer uses to confirm where you actually live — usually a recent utility bill, bank statement, or government letter showing your name and address. It’s the second half of KYC, after photo ID, and it exists to satisfy anti-money-laundering rules.

Why it matters: crypto cards are residency-gated, so this document is where a lot of applications quietly die. The address on the bill has to match the country the card supports and the address on your ID — a recent move, a bill in a partner’s name, or a document the system won’t read can all trigger a rejection. Worse, some issuers make a final rejection terminal — no second attempt — so get the document right the first time.

For example: Gnosis Pay runs KYC through regulated partners and can reject you for “region not supported” even when you sit inside a broadly available country — and a final KYC rejection permanently closes the account, with no re-submission allowed (your funds in the Safe stay yours, but the card is gone for good). As of June 2026. ether.fi likewise requires valid proof of address in a supported jurisdiction before it will even activate your virtual card.
