How a Germany IBAN is structured

A Germany IBAN is read left to right: a 2-letter ISO 3166 country code (DE), 2 MOD 97 check digits, then a 18-character BBAN. The BBAN is split into 2 fields: 8 digits, 10 digits.

How Germany IBAN check digits work

The two digits at positions 3–4 are a MOD 97-10 checksum computed from the country code and the BBAN. To verify it, the IBAN is rearranged (BBAN first, country code and check digits last), letters are converted to numbers (A = 10, B = 11, …), and the whole integer is taken mod 97. A valid IBAN has a remainder of 1. This catches any single-digit typo and most transposition errors — which is why a one-character mistake is enough to make a Germany IBAN fail validation instantly.

Germany IBAN FAQ

How long is a Germany IBAN?
A Germany IBAN is always 22 characters long: 2 letters for the country code (DE), 2 check digits, and a 18-character BBAN. Any Germany IBAN that is shorter or longer than 22 characters is invalid.
What country code does a Germany IBAN start with?
A Germany IBAN starts with the ISO 3166 country code DE. The first two characters are always DE, followed by two MOD 97 check digits, then the country-specific BBAN.
How do I validate a Germany IBAN?
Paste the IBAN into the validator on this page — it checks the character set, the 22-character length, and the MOD 97 check digits, all in your browser. You can also open the full IBAN validator with a Germany example pre-filled.
Does a valid Germany IBAN mean the account exists?
No. Validation only confirms the IBAN is structurally well-formed and the check digits are correct per ISO 13616. It does not verify the account exists, is open, or belongs to anyone. Always confirm with the recipient or their bank before sending money.

⚠️ Validation only checks structure and check digits against ISO 13616. A valid Germany IBAN does not guarantee the account exists or is open. Always confirm with the recipient or their bank before initiating a transfer.
