Last modified: April 3, 2025

The ABA Routing Transit Number (ABA RTN) generator creates 9-digit numeric codes used to identify financial institutions in the United States. These codes, also known as routing numbers or ABA numbers, are used for processing electronic transfers, including ACH (Automated Clearing House) and wire transfers, as well as check processing.

The code follows the format XXXXYYYYC, where:

• XXXX represents the Federal Reserve Routing Symbol
• YYYY denotes the ABA Institution Identifier
• C is the check digit, used for validating the routing number
