IBAN Structure Belgium

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Belgium has one of the shortest IBANs in Western Europe at 16 characters, following the pattern BEkk BBBC CCCC CCKK. After BE and two check digits come a 3-digit bank code (e.g. 539 for Bank Degroof, 053 for Argenta), the 7-digit account number and two national control digits. The old 12-digit BBAN form (3 + 7 + 2) is still familiar in Belgian business, but every bank has required the IBAN on payment orders since 2014. For payments from EU/EEA banks to Belgium, required routing details depend on the bank, currency and route; check them in advance with your bank.

Structural fields are based on the official SWIFT IBAN Registry. The editorial method and validation boundary are documented on our German editorial page (German).

Frequently asked questions

How do I check the length of an IBAN from Belgium?
Remove spaces and count 16 characters. The first two characters are BE; the remaining positions follow BEkk BBBC CCCC CCKK. A different length is formally invalid for this country format.
What do the check digits in a Belgium IBAN mean?
The two check digits are calculated from the complete IBAN using ISO 7064 MOD-97. They help detect format and transcription errors. A passing checksum does not confirm that an account exists or identify its account holder.
What should I do when an IBAN is formally invalid?
Check the country code, character count, letters and digits, and the check digits. Compare the entry with your bank records or ask the bank for the correct IBAN. This checker validates structure and checksum; it does not verify account ownership or payment approval.
