El Salvador IBAN validator

An El Salvador IBAN is 28 characters: “SV”, two check digits, a 4-letter bank code, and a single 20-digit account number with no separate branch or currency segment breaking it up. El Salvador has used the US dollar as its official currency since 2001, having retired its own colón — one of a small number of countries that runs its entire banking system on a foreign currency rather than issuing its own, which is worth knowing if you’re used to seeing a currency spelled out explicitly the way Mauritius or Seychelles do in their IBANs; El Salvador’s format doesn’t need a currency code at all since there’s only one currency to denominate an account in. The Central Reserve Bank of El Salvador (Banco Central de Reserva) oversees the domestic system that this IBAN format sits on top of.

How this validator works

This tool checks the “SV” prefix, confirms the bank code is exactly 4 letters, and confirms the account number is exactly 20 digits, then runs the mod-97 checksum (ISO 7064) a correctly generated El Salvador 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 the Central Reserve Bank of El Salvador or any commercial bank there. If an El Salvador IBAN fails, split the 20-digit account number into groups of four or five before re-checking it — a single unbroken run that long is where a dropped digit hides best.

Scope: El Salvador 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.
