BIC Format and Bank Directory Limits

Who this guide is useful for

Users reviewing BIC/SWIFT fields on invoices, vendor records, payment forms, and developer test cases.

The visible BIC structure

A BIC is usually 8 or 11 characters. BankCodeKit can parse the visible structure into business party prefix, country code, location/business party suffix, and optional branch identifier.

Business party prefix: 4 alphanumeric characters.
Country code: 2 alphabetic characters.
Location/business party suffix: 2 alphanumeric characters.
Optional branch identifier: 3 alphanumeric characters.

What a format check can do

A format check can confirm length and allowed character placement. It can help spot obvious mistakes before a value is copied into another system.

Directory and connectivity limits

BankCodeKit does not use a licensed BIC directory and does not confirm whether a bank exists, whether a BIC has directory status or Swift network connectivity, or whether a payment can be routed through a specific network.

Practical BIC examples

The examples below show format patterns only. They are not proof of a live bank relationship or payment route.

BIC8 pattern: DEUTDEFF
BIC11 pattern: NWBKGB2LXXX
Business party prefix example: first four alphanumeric characters.
Branch identifier example: optional last three alphanumeric characters.

FAQ

Can BankCodeKit tell if a BIC is in a licensed directory?

No. BankCodeKit validates format only and does not use licensed BIC directory data.

What does connected vs non-connected BIC mean here?

That context relates to directory and messaging status. BankCodeKit does not verify that status.

Can an 8 character BIC be valid format?

Yes. BIC format can be 8 characters, with an optional branch identifier making it 11 characters.

Should I verify a BIC before payment?

Yes. Verify real payment details with your bank, payment provider, invoice issuer, or recipient.

Sources and update note

BankCodeKit uses visible BIC/SWIFT format rules only and checks them locally in the browser. It does not use a licensed BIC directory and does not confirm directory status, bank existence, or Swift network connectivity. The official Swift BIC / ISO 9362 information is used as a reference source, and periodic review does not imply live directory accuracy.
