What to expect of a routing number database

Each financial institution record contains more than one dozen optional fields, updated daily by Lyons Commercial Data’s own Research and Content Management Department to ensure the most accurate bank routing number data available. Additionally, each record includes any old, previously used, or rarely used routing numbers (retired routing numbers are available upon request).
