Jordan IBAN validator

A Jordan IBAN is 30 characters, tied with Kuwait among the longest IBAN formats in current use, but it gets there by a different route: instead of one long account block, Jordan splits its structure into four distinct pieces — “JO”, two check digits, a 4-letter bank code, a separate 4-digit branch code, and an 18-character account-number block. That standalone branch-code segment is the detail worth noting: most Middle Eastern IBANs fold branch information into the account block itself, but Jordan gives it its own four digits. Anyone wiring money into Jordan, paying a Jordanian business, or completing a payment form that asks for an IBAN needs each of these four blocks correct.

How this validator works

The check here starts with the “JO” prefix, then verifies four 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) Jordanian banks use to generate valid IBANs. Everything runs in-browser only — no server call, no account, no tracking. Because the branch code sits as its own 4-digit block right after the bank code, it’s a common place for a digit to get transposed when an IBAN is copied by hand.

What a pass doesn’t tell you

A pass tells you the four blocks are correctly sized and the whole string is internally consistent — it says nothing about whether the account is open, active, or belongs to the payee you expect. This tool does no lookup against Jordanian bank or branch registries and never contacts the Central Bank of Jordan. If a Jordan IBAN fails, check the branch-code block first, since it’s easy to conflate with the bank code when reading the number quickly.

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