Register Your Organization

Before applying for an LSTA grant, organizations must already have (or register for) the following numbers to complete your grant application:

  1. Administrative Unit Number (AUN): An AUN is a nine-digit number assigned by the Pennsylvania Department of Education (PDE) to identify entities such as libraries, school districts, intermediate units, higher education institutions, professional education associations, etc.  You can verify an already existing AUN at PDE’s Educational Name and Address (EdNA) website.  Or, to register for an AUN, email

  2. Pennsylvania Vendor Number: This number is required for organizations that receive payments or grants from the Commonwealth.  If you are registering for the first time and do not think you’ll ever provide goods or services that the commonwealth would purchase, you should register for a Pennsylvania Non-Procurement Vendor Number. A W9 (PDF) form is needed to apply for a vendor number.

    You can verify an already existing vendor number on the Commonwealth of Pennsylvania Supplier Lookup Tool.

    For questions about Pennsylvania Vendor Numbers, review the Pennsylvania Office of the Budget’s Non-Procurement Vendor Help  or contact the Vendor Data Management Unit at

  3. Dun & Bradstreet D-U-N-S® Number: A D-U-N-S® number is a unique nine-digit identifier for businesses. It is used to establish a business credit file, which is often referenced by lenders and the federal government to help predict the reliability and/or financial stability of the organization. To register for or to verify an already existing D-U-N-S® Number, visit the Dun and Bradstreet website.

  4. Federal Employer Identification Number (FEIN):  A 9-digit code used by businesses in order to classify and identify them as a tax payer, for banking services and other official and legal purposes.  More information regarding FEINs can be found on the IRS website.
