Chad IBAN validator
How the IBAN format works
- Format
- TD + 2 check digits + 25 digits (27 chars) — used in practice, not in the official SWIFT IBAN registry
- Example
- TD6200000000000000000100008
Things to watch for
- Chad is not in the official SWIFT IBAN registry — this 27-character format is used in practice by Chadian banks, not formally standardized by SWIFT/ECBS
- Chad 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 Chadian bank
^TD[0-9]{25}$A Chadian IBAN-style account number is 27 characters: “TD”, two check digits, then 25 digits with no letters anywhere — for example TD6200000000000000000100008. Chad is not in the official SWIFT/ECBS IBAN registry, but it’s a member of the same monetary union as five neighbors — Cameroon, Central African Republic, Congo-Brazzaville, Equatorial Guinea, and Gabon — sharing the central bank BEAC (Banque des États de l’Afrique Centrale) and the Central African CFA franc (XAF).
As a landlocked country reliant on cross-border banking relationships with Cameroon and the Central African Republic for much of its international trade, Chad follows the BEAC-wide convention exactly: 27 characters, fully numeric after the check digits, no letter-based bank code separating any block.
How this validator works
This tool checks the “TD” prefix, confirms exactly 25 digits follow the two check digits, and runs the mod-97 checksum (ISO 7064) the number must satisfy. Everything runs client-side, with nothing sent to a server.
What a pass doesn’t tell you
A pass confirms the 27 characters are internally consistent — not that the account is open or that Chad has formal SWIFT IBAN registration. This tool performs no lookup against BEAC or any Chadian bank.
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 Chad part of the official SWIFT IBAN registry?
No. Chad is not in the official SWIFT/ECBS IBAN registry. Chadian banks, under the regional central bank BEAC, use a 27-character, all-numeric IBAN-shaped account number that satisfies the mod-97 checksum without formal SWIFT registration.
What does a Chadian IBAN-style number look like?
27 characters: 'TD', two check digits, then 25 digits and no letters — for example TD6200000000000000000100008.
Does a valid checksum mean the account is real?
No. It confirms the 27 characters are mathematically consistent under mod-97, entirely client-side. Confirming the account itself requires the account-holder's bank or BEAC, neither of which this tool queries.
