Greip

IBAN Checker & IBAN Validator

Paste or type an IBAN with or without spaces. Greip checks format and checksum for the country code, then returns country and banking metadata when valid. This does not confirm the account exists or can receive funds.

Examples

What is an IBAN?

An International Bank Account Number (IBAN) is a standardized account identifier used mainly in Europe and other participating countries. It starts with a two-letter country code, followed by check digits and a domestic basic bank account number (BBAN).

IBANs reduce transfer errors by encoding country-specific length and format rules in one string.

What input does this IBAN validator accept?

Enter the full IBAN in machine format (no spaces) or human format (groups of four characters). Letters are case-insensitive. Greip normalizes input before validation.

Each country defines its own length and character set. If the country code or length does not match published rules, the tool returns Valid IBAN: No.

Example IBANs you can check

These sample values are valid structures you can use to explore results (do not send funds to demo accounts):

  • United Kingdom: GB82WEST12345698765432
  • Germany: DE89370400440532013000
  • Belgium: BE71096123456769

Select an example above the form or paste your own customer-supplied IBAN for the same validation flow.

What each result field means

Results appear under IBAN Data on this page:

  • Valid IBAN: Structural and checksum validation for the stated country.
  • IBAN: Human-readable formatted value when valid.
  • Country, ISO-3166, currency: Issuing jurisdiction metadata.
  • Central bank name / URL: Reference institution for the country when available.
  • EU member, SEPA member, IBAN length, SWIFT issued: Routing and scheme context for payouts.

The free tool does not return bank name or BIC fields shown in the full API response for some countries.

What IBAN validation does not prove

A valid IBAN means the string matches format and checksum rules. It does not prove the account is open, that you own it, that the name on file matches, or that a transfer will succeed. Greip does not perform live account verification or micro-deposit confirmation on this page.

Use validation to catch typos and wrong-country IBANs before initiating payouts, then apply your bank's own confirmation steps.
