How to Find Your CO Bank's Routing Number

About SWIFT Codes in CO
SWIFT codes (also known as BIC codes) are assigned to individual banks, not to states or regions. Each bank that participates in international wire transfers has its own unique SWIFT code. You can find the SWIFT code for any CO bank by clicking on its name in the table above.
Note: Not all banks have SWIFT codes—smaller community banks and credit unions typically don't offer international wire transfers directly. In such cases, they may use a correspondent bank's SWIFT code for international transactions.
Using Routing Numbers for Transfers
- Domestic transfers (ACH): Use the 9-digit ABA routing number shown above
- Domestic wire transfers: Usually the same routing number (verify with your bank)
- International wire transfers: You'll need the bank's SWIFT code plus the routing number
