Yemen IBAN validator

A Yemeni IBAN is 30 characters, among the longest IBAN formats in current use: “YE”, two check digits, a 4-letter bank code, a separate 4-digit branch code, and an 18-character account number that — unlike some equally long formats — can mix letters and digits rather than digits only. Jordan uses the same four-block shape and reaches the same 30-character length, so the two look alike on paper; they differ by their country code and each country’s own bank and branch registries rather than by the character rules of that final block. Yemen’s banking sector has operated under real strain through years of conflict, including disruption to normal clearing and correspondent-banking relationships, which makes getting payment details exactly right even more important when money does move through it.

How this validator works

The check here verifies the “YE” prefix, then three segments in order — a 4-letter bank code, a 4-digit branch code, and an 18-character alphanumeric account number — before running the mod-97 checksum (ISO 7064) a correctly generated Yemeni IBAN must satisfy. Everything runs in-browser only, with nothing sent to a server.

What a pass doesn’t tell you

A pass confirms the four blocks are correctly sized and the whole string is internally consistent — not that the account is open, active, or belongs to the payee you expect. This tool does no lookup against any Yemeni bank or the Central Bank of Yemen. If a Yemeni IBAN fails, check the branch-code block first, since it sits right after the bank code and the two are easy to run together when reading quickly.

Scope: Yemeni IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Use this to catch a typo before a transfer fails; the bank confirms the account itself.
