Guatemala IBAN validator
How the IBAN format works
- Format
- GT + 2 check digits + 4-letter bank code + 2-digit currency code + 18-char account identifier (28 chars)
- Example
- GT82TRAJ01020000001210029690
Things to watch for
- 28 characters total
- Checks structure and checksum only, not that the account exists
^GT[0-9]{2}[A-Z]{4}[0-9]{2}[A-Z0-9]{18}$A Guatemalan IBAN is 28 characters: “GT”, two check digits, a 4-letter bank code, a 2-digit currency code, and an 18-character alphanumeric account identifier. The currency code is the detail that sets Guatemala’s format apart from most other IBANs on this site — rather than tacking a currency marker onto the very end of the string the way Mauritius or Seychelles do with a trailing 3-letter code, Guatemala places a compact 2-digit currency indicator right in the middle, immediately after the bank code and before the account identifier itself. Guatemala’s central bank, Banguat (Bank of Guatemala), issues IBANs across a banking sector that also handles a large volume of remittances sent home by Guatemalans working abroad, so an accurate IBAN matters both for domestic transfers and for money arriving from overseas.
How this validator works
This tool checks the “GT” prefix, confirms the bank code is 4 letters, the currency code is 2 digits, and the account identifier is 18 alphanumeric characters, then runs the mod-97 checksum (ISO 7064) a correctly generated Guatemalan IBAN must satisfy — entirely in your browser, with nothing sent to a server.
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 expect. This tool does no lookup against Banguat or any Guatemalan bank. If a Guatemalan IBAN fails, check the 2-digit currency code first — it’s a short block sandwiched between two longer ones and easy to miscount past.
Scope: Guatemalan IBAN structure and mod-97 checksum validation only — not payment processing, bank verification, or confirmation an account is active. Catch the typo here; confirm the account with the bank.

IBAN FAQ
What does a Guatemalan IBAN look like?
28 characters: 'GT', two check digits, a 4-letter bank code, a 2-digit currency code, and an 18-character alphanumeric account identifier — for example GT82TRAJ01020000001210029690.
Why does a Guatemalan IBAN include a currency code in the middle of the string?
It's a 2-digit segment identifying the account's currency, placed right after the bank code — a different approach from IBANs like Mauritius's or Seychelles's, which put a 3-letter currency code at the very end instead.
Does this tool confirm my Guatemalan IBAN belongs to a real account?
No. It checks only the structure and mod-97 checksum, entirely client-side — it does not contact Banguat (Bank of Guatemala) or any commercial bank, so it can't confirm the account is open or active.
