Which portal applies to my federal transaction?
According to SAM.gov, entity registration is required if an organization wants to apply for federal awards as a prime awardee, and that registration allows the entity to bid on government contracts and apply for federal assistance. SAM.gov also says it assigns a Unique Entity ID during registration, but a user who only needs a UEI, or who only conducts certain transactions such as reporting as a sub-awardee, may not need full registration. SAM.gov directs users to sign in through Login.gov to access and complete a SAM.gov profile. PIEE training states that every vendor must register in the Procurement Integrated Enterprise Environment for the specific applications they want to use, and that WAWF registration gives automatic access to myInvoice. GSA’s Vendor Support Center says contracts must be registered there before participating in GSA eBuy, and that registration requires a contract number, SAM UEI, and an authorized negotiator.
Process
- 1Confirm the required transaction
Decide whether you need SAM.gov entity registration, a PIEE application account, or GSA VSC contract registration.
- 2Set up access
Use Login.gov to sign in to SAM.gov; for PIEE, establish the personal account required for the application.
- 3Complete the portal-specific registration
Provide the information required by the portal, such as entity details for SAM.gov, the needed CAGE-related setup for PIEE, or contract details for VSC.
- 4Check status and renew when needed
SAM.gov says registration must be renewed every 365 days, and it can take up to 10 business days to become active.
If you choose only to get a Unique Entity ID in SAM.gov, you cannot apply directly for federal awards. SAM.gov says that option is separate from full registration.
