SAM.gov registrations are dense. They're built for compliance, not readability. If you've ever tried to evaluate a potential teaming partner by pulling their SAM profile, you've probably spent ten minutes staring at acronyms and wondered which of them actually matter.
Here's a field-by-field breakdown of what you're actually looking at.
The UEI is a 12-character alphanumeric code assigned by SAM.gov. It replaced the DUNS number in April 2022. Every entity doing business with the federal government has one. This is the primary key — it's what you use to look up award data on USASpending.gov and verify identity across systems.
If someone gives you a company name but no UEI, look it up before you rely on anything else they've told you. Two companies can have similar names; UEIs are unique.
Commercial and Government Entity code — a five-character alphanumeric assigned by the Defense Logistics Agency. Older than UEI and still required for many defense contracts. If a company has a CAGE code, they've been in the government contracting space long enough to have gone through the DLA's process. That's a rough proxy for experience level, nothing more.
The legal business name is what's registered with the state. The DBA (doing business as) is what they might call themselves in marketing materials. If these differ significantly, make sure you know which name appears on past performance and which name will appear on proposal cover pages. Mismatches cause compliance headaches.
This is binary. Active means they're current. Inactive means their registration has lapsed — and you cannot legally be awarded a federal contract with an inactive registration. Before investing time in a teaming relationship, verify the status is Active and check the expiration date.
SAM registrations expire annually. Companies are supposed to renew before they lapse, but plenty don't — especially smaller firms that aren't actively bidding. An expiration date within 60 days is worth flagging in a BD conversation. An expired registration is a problem that can delay or kill an award.
How long have they been registered? A company that registered last month is a different risk profile from one registered in 2009. Neither is automatically good or bad, but longevity on SAM correlates with experience navigating the federal market.
The code they've designated as their primary line of business. This is what most search tools use to find contractors by capability. It also determines size standard eligibility — each NAICS has a different revenue or employee threshold for "small business" classification.
A company can list multiple NAICS codes. More codes isn't necessarily better — sometimes it reflects a diversified business, sometimes it reflects wishful thinking about capabilities. When evaluating a potential teaming partner, look for NAICS overlap with the specific requirement, not just the presence of the code on their list.
Also worth noting: the size standard for the primary NAICS is what determines whether they qualify as a small business for set-asides. Having a relevant NAICS code listed doesn't mean they're small under that code.
This is the section that gets a lot of attention in BD conversations. The socioeconomic categories include:
Two things to know. First: these categories are self-certified in SAM.gov, with the exception of 8(a) (SBA-certified) and SDVOSB (VA-verified for VA contracts, or self-certified for non-VA). Don't assume a certification is verified just because it appears on the SAM profile. Second: these categories determine set-aside eligibility, which in turn determines which solicitations a prime can pursue and which subs add real value to their team.
Product and Service Codes are a separate classification system from NAICS, used by federal buyers to categorize what they're buying. Where NAICS describes the company, PSC codes describe the work. A company can list PSC codes that align with their capabilities, but this field is less standardized than NAICS and harder to rely on for research.
If you're using SAM.gov to find primes, NAICS search is more reliable. PSC is more useful when you're looking at specific contract awards to understand what a prime actually delivered.
SAM registrations include a Government Business POC and an Electronic Business POC. These are typically administrative contacts, not BD contacts — often the CFO, contracts manager, or an administrator. Don't cold-email the SAM POC expecting a BD conversation. They may not even know who handles teaming inquiries.
The SAM contacts are useful for one thing: confirming the company is real and has a legitimate person behind it. For actual outreach, find the BD team through the company website or LinkedIn.
When you pull a SAM profile for due diligence on a potential teaming partner, here's the checklist that actually matters:
Then cross-reference with USASpending.gov to see what they've actually won. The SAM registration tells you who they say they are; USASpending tells you what agencies have decided to pay them to do.
PrimeFinder searches SAM.gov via API and pulls structured registration data for hundreds of contractors at once — sorted, filtered, and ready for outreach. No more manual lookups.
