Algeria IBAN validator
How the IBAN format works
- Format
- DZ + 2 check digits + 24 digits (26 chars) — used in practice, not in the official SWIFT IBAN registry
- Example
- DZ380000000000000000100001
Things to watch for
- Algeria is not in the official SWIFT IBAN registry — this 26-character format is used in practice by Algerian banks, not formally standardized by SWIFT/ECBS
- The mod-97 checksum is mathematically valid for a 26-character Algerian IBAN, but the length itself isn't SWIFT-standardized the way it is for registry countries like neighboring Tunisia
- Checks format and checksum only — does not confirm the account exists or is held at a real Algerian bank
^DZ[0-9]{24}$An Algerian IBAN-style account number runs 26 characters: “DZ”, two check digits, then 24 digits with no letters anywhere in the string — for example DZ380000000000000000100001. Algeria sits outside the official SWIFT/ECBS IBAN registry, unlike its Maghreb neighbor Tunisia, which is a registered member. That distinction matters for what you can rely on: Tunisia’s IBAN format is formally standardized down to the character, while Algeria’s 26-character convention is what banks and clearing systems there use in practice, without a SWIFT-catalogued specification behind it.
How this validator works
This tool confirms the “DZ” prefix, checks that exactly 24 digits follow the two check digits, and then runs the real mod-97 checksum (ISO 7064) — the same arithmetic that governs every properly formed IBAN, registered or not. Everything happens in your browser; nothing you type is sent anywhere.
What a pass doesn’t tell you
A pass confirms the 26 characters are internally consistent under mod-97 — not that the number belongs to a real, open account, and not that Algeria has adopted IBAN through any formal standards body. This tool does no lookup against the Bank of Algeria (Banque d’Algérie) or any commercial bank operating there.
Scope: format and mod-97 checksum validation only, for a non-SWIFT-registered format used in practice — not payment processing, not registry confirmation, not proof an account is active.

IBAN FAQ
Is Algeria an official IBAN country?
No. Algeria is not in the official SWIFT/ECBS IBAN registry. Algerian banks and payment processors use a 26-character IBAN-shaped account number in practice, and it passes the same mod-97 checksum as a registered IBAN, but the format itself was never formally catalogued by SWIFT.
What does an Algerian IBAN-style number look like?
26 characters: 'DZ', two check digits, then 24 digits with no letters anywhere — for example DZ380000000000000000100001. There's no separate bank-code or branch-code block marked off by letters; it's numeric end to end.
Does a passing checksum mean the Algerian account exists?
No. This tool checks structure and the mod-97 checksum only, entirely client-side. It doesn't contact any Algerian bank or the Bank of Algeria, so a pass tells you the number is well-formed, not that an account behind it exists.
