Routing Number Definition

A routing number is a nine-digit bank code that appears on the bottom of negotiable documents such as checks. The numeric code identifies the financial institution upon which the negotiable document draws. Basically, a routing number identifies a particular financial institution. The first four digits of the routine number indicate a specific Federal Reserve routing symbol, the next four digits indicate a specific financial institution, and the ninth digit is a check digit used to guarantee information accuracy. You may be asked to provide a routing number when signing up for electronic deposits at work-in this case, you should contact your bank or credit union to obtain the correct number.
