Life after DUNS

If you have done any work, within the past 60 years with the Federal Government, then you have probably heard of the Data Universal Number System or DUNS. It is the data format that identifies organizations doing business with the government.

GSA, who administers the program, awarded a new contract in 2018 to Ernst & Young to dispense new organization identifiers. The new Unique Entity IDs (UEIs) will replace the current DUNS numbers. Ernst & Young will also manage the transition. (Nextgov October 13, 2021)

GSA is working with agencies to test the old and the new numbers prior to the final cutover, planned for April 2022. However, before the switch from DUNS numbers to UEIs takes place, GSA through the Integrated Award Environment program would like to work with some testers to ensure smooth sailing before the final cutover. (ibid)

According to, “volunteers get scripts which walk through various Unique Entity ID ( functions, such as requesting and receiving a Unique Entity ID ( or how to deal with error scenarios. Each test script takes about 20 minutes or less. You test at your own pace and send us your feedback.” This is extremely necessary because the DUNS is a nine-number string and the UEI is a 12-digit alphanumeric code. (ibid)

The program office recently released new help resources through the Federal Service Desk under a dropdown option under FAQ. It is also accessible through a large green button icon on the homepage. (ibid)

This large-scale modernization touches every single entity that does business with the federal government. GSA is hopeful their call for superusers will enable a smooth transition.
