Decode all the BIC/SWIFT codes in a list at once under the ISO 9362 structure; see the institution, country, location and branch codes, and download as CSV.

Privacy: The calculation runs in your browser; the full IBAN, account number, amount and reference you enter are not sent to a server, logged or passed to analytics. Some tools may pass only a non-sensitive term (e.g. bank code, BIC, currency) to a lookup service for search/matching. Per-tool detail: Privacy.
How does this tool calculate?
Definite — mathematical/standard result- Method/formula used
- Structural decoding of each BIC under ISO 9362 (institution·country·location·branch); run in bulk.
- Data used
- ISO 9362 (BIC) and ISO 3166 country codes

How is this tool used?
- Paste the list or upload a CSV; there should be one BIC per line (8 or 11 characters).
- Validate all: The tool splits each BIC into its components (institution · country · location · branch) under ISO 9362 and checks its structural validity.
- Download CSV: Download the result and use it for accounting/integration.
This tool checks the structural validity of a BIC; it does not show that the institution is active or reachable on a specific route. Everything runs in your browser.
For single decoding see BIC/SWIFT lookup; for the code structure see our What is BIC article.
