eRA Information: Unavailable April 1 – 4, 2022 for Transition from DUNS to UEI

This message is for your information. Note that is run by the General Services Administration.

To complete the transition from Dun & Bradstreet DUNS numbers to Unique Entity Identifiers (UEI), will be unavailable beginning on Friday, April 1, 2022, at 8 p.m. (ET) until no later than 9 a.m. (ET) Monday, April 4, 2022. The downtime does not directly impact usage of eRA modules.

To reduce the burden on applicant organizations, GSA will be issuing an automatic 60-day extension on SAM registrations with an expiration date ranging between Friday, March 18 and Monday, April 18, 2022.

The downtime means that institutions that use eRA Commons will not be able to access during that period to apply for or manage SAM registrations.  

When returns to service, DUNS Numbers will no longer be displayed or accepted for entity registration, reporting, or searching. The UEI will be the identifier of record. You can get a UEI any time after April 4 without using a DUNS Number.
