Honduras IBAN validator
How the IBAN format works
- Format
- HN + 2 check digits + 4-letter bank code + 20-digit account number (28 chars)
- Example
- HN54PISA00000000000000123124
Things to watch for
- 28 characters total — the 4-letter bank code comes right after the check digits, before the numeric account
- Checks structure and checksum only, not that the account exists
- Honduras is one of the smaller set of Latin American countries that assigns IBANs
^HN[0-9]{2}[A-Z]{4}[0-9]{20}$A Honduran IBAN runs 28 characters: “HN”, two check digits, a 4-letter bank code, then a 20-digit account number — for example HN54PISA00000000000000123124. Central America’s IBAN formats vary more than you’d expect from neighboring countries: Guatemala tucks a 2-digit currency code into the middle of its string, Costa Rica uses no letters anywhere, and Honduras instead pairs a compact 4-letter bank identifier with a long, purely numeric account block. Hondurans abroad send a significant flow of remittances back through the domestic banking system, so an accurately entered IBAN matters for money arriving from overseas as much as for local transfers.
How this validator works
This tool checks for the “HN” prefix, confirms the bank code is exactly 4 letters and the account number is exactly 20 digits, then runs the mod-97 checksum (ISO 7064) a correctly generated Honduran IBAN must satisfy — entirely in your browser, with nothing sent to a server and no signup required.
What a pass doesn’t tell you
A pass confirms the 28 characters are correctly structured and internally consistent — not that the account is open, active, or belongs to whoever you intend to pay. This tool does no lookup against BCH or any Honduran commercial bank. If a Honduran IBAN fails, recheck the 20-digit account block first — it’s the longest unbroken stretch in the string and easy to miscount digits within.
Scope: Honduran IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Catch the typo here; confirm the account with the bank.

IBAN FAQ
What does a Honduran IBAN look like?
28 characters: 'HN', two check digits, a 4-letter bank code, and a 20-digit account number, for example HN54PISA00000000000000123124. Everything after the bank code is plain digits — no embedded currency letters.
Why is a Honduran IBAN longer than a Costa Rican one?
Costa Rica compresses its bank, branch, and account details into a single 18-digit numeric block for 22 characters total. Honduras keeps a separate 4-letter bank code ahead of a full 20-digit account number instead, which is what pushes its IBAN out to 28 characters.
Does this tool confirm the Honduran account is open?
No. It checks structure and the mod-97 checksum only, entirely client-side. Confirming an account is open or active requires the account-holder's bank or the Central Bank of Honduras (BCH).
