Military users can access support through the DSN line at 94-866-606-8220.
Self-help resources on FSD.gov include searchable FAQs, training videos, and documentation specific to entity registration and federal role management. Maintaining an active SAM registration is essential for eligibility to pursue federal contracts and grants with U.S. government agencies.
The customer feedback mechanism, accessible via the “Provide Feedback” button on every SAM.gov page, allows users to submit anonymous comments for system improvements, though this channel isn’t intended for technical support requests.

Frequently Asked Questions
How Long Does It Take for My SAM.Gov Registration to Become Active?
SAM.gov registration processing time typically requires 6-8 weeks for full activation, despite official guidance suggesting 7-10 business days.
Recent system updates have extended timelines to 10+ weeks in some cases.
Activation notification methods include email confirmation and status updates in the Entity Workspace dashboard.
Organizations should prepare documentation thoroughly, verify UEI and CAGE codes before submission, and monitor their workspace regularly.
Entity complexity, documentation errors, and seasonal volume fluctuations can greatly impact processing duration.
Can I Change My Entity’s Unique Entity ID After Registration?
No, a Unique Entity ID cannot be changed after registration.
The system maintains immutable identifiers that remain permanently associated with an entity.
While registration updates for legal business names or addresses are possible, entity id changes are not permitted under any circumstances.
Organizations should continue using their assigned ID for all federal transactions, even after structural modifications.
For data corrections, entities can make updates via their SAM.gov workspace without altering their Unique Entity ID.
What Happens if My Login.Gov Email Differs From My SAM.Gov Email?
When login.gov and SAM.gov emails differ, users may experience account access issues.
Email synchronization between both systems is essential for proper functionality. When mismatched, SAM.gov treats these as separate accounts, potentially blocking access to procurement opportunities.
Users must complete login.gov verification of any new email address before changes take effect. To resolve this issue, users should update their email in login.gov first, verify it, then manually update their SAM.gov profile to match.
Does SAM.Gov Support Integrate With Other Federal Procurement Systems?
SAM.gov offers robust federal procurement integration with multiple government systems. The platform connects with the Federal Procurement Data System (FPDS) and other Integrated Award Environment (IAE) components, creating a unified procurement ecosystem.
SAM.gov compatibility is enhanced through the Unique Entity ID, which serves as the official government-wide identifier for federal awards. This standardization enables agencies to access consistent vendor information, streamline contract management, and improve transparency across the entire federal acquisition process.
How Do I Transfer Entity Administrator Rights to Another User?
To transfer entity administrator rights in SAM.gov, the process requires a notarized letter on company letterhead.
The letter must specify the new administrator’s details, including their email address and justification for the change. The new user must have a SAM User Account already created.
If available, the current administrator can invite the new user, or submit the authorization letter to SAM.gov for approval.
After verification, the user transfer will be completed, granting the new entity administrator full access.
