Libya IBAN validator

A Libyan IBAN is 25 characters, entirely numeric: “LY”, two check digits, a 3-digit bank code, a 3-digit branch code, and a 15-digit account number. That puts it at the same overall length as São Tomé and Príncipe’s IBAN, though the two format their digits differently — São Tomé and Príncipe adds a pair of national check digits at the very end that Libya’s format doesn’t use, relying instead on a longer 15-digit account block to make up the difference. Among Libya’s own North African neighbors, the format sits between Tunisia’s shorter 24-character, all-numeric IBAN and Egypt’s longer 29-character one, following the same regional pattern of splitting a numeric bank/branch/account block after the two IBAN check digits. The Central Bank of Libya oversees the domestic system this IBAN format describes.

How this validator works

This tool checks the “LY” prefix and confirms all 23 remaining characters are digits, split into a 3-digit bank code, 3-digit branch code, and 15-digit account number, then runs the mod-97 checksum (ISO 7064) — entirely in your browser, nothing sent to a server.

What a pass doesn’t tell you

A pass confirms the 25 digits are correctly structured and internally consistent — not that the account is open or belongs to whoever you expect. This tool does no lookup against the Central Bank of Libya or any commercial bank there. If a Libyan IBAN fails, verify the 3-digit bank and 3-digit branch codes first, since two short matching-length blocks sitting side by side are easy to swap when copying by hand.

Scope: Libyan IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Use it to catch a typo before a transfer fails.
