What Is a BIC/SWIFT Code?
A Bank Identifier Code (BIC), also known as a SWIFT code, is an 8 or 11 character code that uniquely identifies a financial institution in international transactions. BIC stands for Business Identifier Code and is the ISO 9362 standard used by over 200 countries.
The structure is: 4-letter institution code + 2-letter country code + 2-character location code + optional 3-character branch code. For example, DEUTDEDB is Deutsche Bank's primary code for Germany.
How BIC Validation Works
BIC validation checks the structural integrity of the code against the ISO 9362 specification.
- Length check — must be exactly 8 or 11 characters
- Institution code — first 4 characters must be letters only
- Country code — characters 5-6 must be a valid ISO 3166-1 alpha-2 country code

Validate a BIC/SWIFT Code →When To Use BIC Validation
BIC validation is critical in any international payment workflow where incorrect routing codes result in failed or misdirected transfers.
- Wire transfer forms — validate BIC alongside IBAN to ensure complete and correct payment routing
- Financial data imports — clean bank reference data when importing from legacy systems
- API integrations — validate before calling payment gateway APIs to avoid rejection errors
Frequently Asked Questions
What is the difference between BIC and SWIFT code?
They are the same thing. SWIFT (Society for Worldwide Interbank Financial Telecommunication) manages the BIC registry. The terms are used interchangeably in practice.
When is the 11-character BIC used vs the 8-character version?
The 8-character code identifies the institution and its primary office. The 11-character version adds a branch code. When sending to the head office, you can use the 8-character code or append XXX to get the 11-character equivalent.
Can I validate whether a BIC code is currently active?
Format validation confirms the code follows ISO 9362 rules. To verify if a BIC is currently registered and active in the SWIFT network, you would need access to the SWIFT BIC directory, which is a paid service.
