​DUNS Number changes

​On April 4, 2022, the DUNS Number will no longer be used to identify organizations that receive federal funds. It is being replaced by the Unique Entity ID (SAM). Learn more about the transition from the DUNS Number to the Unique Entity ID (SAM).

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. Unique Entity Identifier (UEI):  A 12-character alphanumeric identifier used in and other federal government systems as a way to identify a unique entity.  Those who are new to can register their entity or just get a Unique Entity ID by signing in to and selecting "Get Started." 

    If you are a sub-awardee who just needs a Unique Entity ID for subaward reporting, choose "Get Unique Entity ID." 

    If you want to bid directly on contracts or grants from the federal government, choose "Register Entity."

    The next time you need to update your entity information or renew your entity registration, go to your workspace to validate your entity information. Learn how here.

  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.
