Bank Routing Number Database - Developer Area

Lyons' Bank Routing Number Database can be downloaded in any common format or as a flat file for easy integration with payment processing systems. Unlimited FTP updates are included with each license. The routing number table can be keyed for look-up based on the dominant financial institution or non-keyed to provide all matching institutions related to a specific routing number.

Each financial institution record contains more than one dozen optional fields, updated daily by Lyons Commercial Data's own Research and Editorial Deparment to ensure the most accurate bank routing number data available. Additionally, each record includes any old, retired, or rarely used routing numbers.

Lyons' bank routing number data is also accessable via Web Services and an online routing number verification tool.
