Austria SWIFT/BIC code validator
How the SWIFT/BIC code format works
- Format
- 8 or 11-character bank identifier code, country code AT in positions 5-6
- Example
- GIBAATWW
Things to watch for
- Structure: 4-letter bank code + AT (country) + 2-character location code, plus an optional 3-character branch code
- An 8-character code (or one ending XXX) refers to the bank's head office, usually in Vienna
- No checksum digit — this is a format check only; it confirms positions 5-6 read AT, not that the bank or branch actually exists
^[A-Z]{4}AT[A-Z0-9]{2}([A-Z0-9]{3})?$An Austrian SWIFT/BIC code identifies the bank on an international wire transfer, paired with the 20-character Austrian IBAN. Every Austrian BIC has AT fixed at positions 5-6, right after the 4-letter bank code, and nearly every major Austrian bank’s location code reads WW — short for Wien, the German name for Vienna. Austria’s largest banking groups also lean heavily into Central and Eastern Europe, with sizeable subsidiary networks across the region, though their head-office BICs stay anchored in Vienna.
Major Austrian bank BIC prefixes
| Bank | BIC | Location |
|---|---|---|
| Erste Group Bank | GIBAATWW | Vienna |
| Raiffeisen Bank International | RZBAATWW | Vienna |
| UniCredit Bank Austria | BKAUATWW | Vienna |
How this validator works
This tool checks that the code is 8 or 11 characters, the first 4 characters are letters, positions 5-6 read AT, and the location and optional branch segments use only letters and digits — entirely in your browser, with nothing sent to a server.
What a pass doesn’t tell you
A pass confirms the code fits the Austrian BIC pattern, not that GIBA, RZBA, or BKAU still names an operating bank, or that the branch suffix is current. A BIC has no checksum digit, so a fabricated code that matches the shape still passes.
Scope: format validation only. Austrian accounts also carry a 20-character IBAN with its own mod-97 checksum — a separate check from the BIC.
SWIFT/BIC code FAQ
What's the SWIFT code format for an Austrian bank?
An Austrian BIC is 8 or 11 characters: a 4-letter bank code, AT fixed at positions 5-6, a 2-character location code, and an optional 3-character branch code — for example GIBAATWW for Erste Group Bank's Vienna head office.
How do I read an Austrian BIC?
In RZBAATWW, RZBA identifies Raiffeisen Bank International, AT is the country, and WW is the Vienna location code — WW is a common SWIFT location code across several Austrian banks, standing in for 'Wien,' the German name for Vienna.
Does an 8-character code work for an Austrian bank?
Yes — the 8-character BIC and its 11-character form ending XXX both point to the same head office and are accepted the same way.
