This message is for your information. Note that SAM.gov is run by the General Services Administration.
To complete the transition from Dun & Bradstreet DUNS numbers to Unique Entity Identifiers (UEI), SAM.gov 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 SAM.gov 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 SAM.gov downtime means that institutions that use eRA Commons will not be able to access SAM.gov during that period to apply for or manage SAM registrations.
When SAM.gov 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.
