Found in the FDL Directory and on the inside flap of depository shipment boxes. The number includes leading zeroes and may contain a letter at the end, for example, 0463B. Each FDL number is unique. Even if you never receive a shipment, it is important that you know your depository library number so GPO can accurately identify the correct library in communication.
The Federal Depository Library Directory (FDL Directory) lists all FDLP libraries and their library type, size, designation status, and contact information. Depository staff who log in can view depository email addresses and edit their library’s FDL Directory entry.
Both designation date and type of designation can be found in the FDL Directory. If the designation date field is blank GPO does not have the original designation documentation.
Passwords give you access to a variety of applications and services. Contact GPO if you are unsure of your passwords. More information about passwords can be found in the Passwords and Accounts Used by Depository Libraries article.
A list of regionals can be found in the FDL Directory. Regional depositories are responsible for developing and managing a comprehensive Federal depository collection and for providing reference and interlibrary loan services to selective depositories within the state or region. They also play a leadership role for all Federal depositories in the state or region and are very good contacts when you have questions about depository collections or depository management issues.
