Equatorial Guinea IBAN validator
How the IBAN format works
- Format
- GQ + 2 check digits + 25 digits (27 chars) — used in practice, not in the official SWIFT IBAN registry
- Example
- GQ3200000000000000000100012
Things to watch for
- Equatorial Guinea is not in the official SWIFT IBAN registry — this 27-character format is used in practice by banks there, not formally standardized by SWIFT/ECBS
- Equatorial Guinea shares its central bank, BEAC, and the Central African CFA franc (XAF) with 5 other Central African countries — none of which are in the official SWIFT registry either
- Checks format and checksum only — does not confirm the account exists or is held at a real bank
^GQ[0-9]{25}$An Equatorial Guinea IBAN-style account number is 27 characters: “GQ”, two check digits, then 25 digits with no letters anywhere — for example GQ3200000000000000000100012. Equatorial Guinea is not in the official SWIFT/ECBS IBAN registry, but as a member of the Central African monetary union it shares its central bank, BEAC (Banque des États de l’Afrique Centrale), and the Central African CFA franc (XAF) with five neighbors — Cameroon, Central African Republic, Chad, Congo-Brazzaville, and Gabon.
Equatorial Guinea is unusual within that group as the only Spanish-speaking member state; Spanish sits alongside French and Portuguese as an official language, a legacy of Spanish colonial administration that doesn’t appear anywhere else on this list of BEAC-zone countries.
How this validator works
This tool checks the “GQ” prefix, confirms exactly 25 digits follow the two check digits, and runs the mod-97 checksum (ISO 7064) a correctly formed account number satisfies. Everything happens in your browser, with nothing sent to a server.
What a pass doesn’t tell you
A pass confirms the 27 characters are internally consistent — not that an account exists, or that Equatorial Guinea has formal SWIFT IBAN registration. This tool performs no lookup against BEAC or any bank operating in the country.
Scope: format and mod-97 checksum validation only, for a locally used but non-SWIFT-registered format — not payment processing or account confirmation.

IBAN FAQ
Is Equatorial Guinea an official IBAN registry country?
No. Equatorial Guinea is not in the official SWIFT/ECBS IBAN registry. Banks there, regulated by the regional central bank BEAC, use a 27-character, all-numeric IBAN-shaped account number that satisfies the mod-97 checksum without formal SWIFT backing.
What does an Equatorial Guinea IBAN-style number look like?
27 characters: 'GQ', two check digits, then 25 digits and no letters — for example GQ3200000000000000000100012.
Does this tool confirm the account is active?
No. It checks structure and the mod-97 checksum only, entirely client-side. Confirming an account requires the account-holder's own bank, which this tool doesn't contact.
