How grants.gov is preparing for SAM’s rollout of the Unique Entity Identifier (UEI)

Miami University doesn’t have a UEI yet, but Research & Sponsored Programs staff will work with PIs to make sure all applications have the correct identifiers, both before and after the transition.

We’re pleased to reblog this recent Grants.Gov Community Blog post.

We are sharing the information so our community is aware of system changes they may notice in the coming months, but there is no action required by Miami University PIs at this time. Once Miami has obtained a UEI from SAM.gov, we will update the institutional codes and identifiers section of our “Budget Resources” webpage. Staff in Research & Sponsored Programs will also work with their assigned PIs to ensure the correct data is entered into applications prior to submission, both before and after the UEI rollout.


Last July, we wrote about SAM.gov’s planned introduction of the Unique Entity Identifier (UEI), which is currently scheduled to replace the DUNS Number around the end of 2020. You can get the most up-to-date information about the UEI rollout on the GSA’s Unique Entity Identifier Update page.

In this post, we begin preparing Grants.gov applicants for what the UEI rollout will look like within the Grants.gov system – particularly, what users will see when working on an application or taking other actions within Workspace.

Fields formerly labeled “DUNS” within Grants.gov will now be labeled “UEI” starting in March 2020.

What’s changing?

It’s really quite simple:

  • Fields formerly labeled “DUNS” within Grants.gov will be labeled “UEI” starting in March 2020 (see the screenshot above).
  • For now, keep entering your DUNS Number when a field labeled “UEI” needs to be filled in.

To review, you can expect to begin seeing UEI labels in March 2020, when Grants.gov plans to implement the label change across the system in preparation for SAM.gov’s transition to the Unique Entity Identifier.
