Every federal sale starts in the same place. Before an agency can award you a contract, before a prime can put you on a subcontract, and before a contracting officer’s market research can find you, your company needs an active registration in SAM.gov, the System for Award Management.

Registration is free. The form itself is not hard. What slows software companies down is everything around the form: a legal name that doesn’t match the one on the website, an address recorded three different ways, a point of contact who left the company, a list of NAICS codes chosen in a hurry. This guide walks through the registration in the order it actually happens and flags where first-time registrants lose weeks.

Before you start: the five things to gather

Collect these before you open SAM.gov. Stopping halfway to hunt for a document is how a registration stalls.

Your exact legal business name and physical address, as they appear on your incorporation documents. Not your brand name, not your mailing address, not a virtual office if your records show something else.
Your Taxpayer Identification Number (EIN) and the name the IRS has on file for it. The registration is checked against IRS records, and a mismatch between the two names stops it.
Banking details for electronic funds transfer: routing number and account number for the account that will receive federal payments.
Names and contact details for your points of contact. Registration asks for an E-Business point of contact and a Government Business point of contact at minimum. Use people who will still be at the company next year, and where you can, a role-based email address.
The NAICS codes that describe what you sell (more on choosing these below).

If your company has moved, renamed, or operates through more than one legal entity, sort that out on paper first. It is the single biggest predictor of a slow registration.

Step 1: Create a Login.gov account

SAM.gov uses Login.gov for sign-in. Create the account with the email address of the person who will manage the registration, and set up multi-factor authentication. This takes minutes, but do it before anything else: every later step happens inside that session.

Step 2: Get your Unique Entity ID

Your Unique Entity ID (UEI) is the twelve-character identifier the government uses for your company across every award, payment and reporting system. It replaced the DUNS number in April 2022, and it is issued free through SAM.gov itself.

Getting the UEI is where entity validation happens. The government confirms that your legal business name and physical address match authoritative records before it will issue an identifier. When they match cleanly, this step is quick. When they don’t, you will be asked for documentation such as incorporation papers or a business license, and you wait for a manual review.

You can stop here if you only need an identifier, for example to be named on a subcontract or to apply for a grant. To receive a prime contract award, keep going.

Step 3: Complete the full entity registration

The full registration is a longer form in several sections:

Purpose of registration. Choose between federal assistance awards only (grants) and all awards. A software company selling to agencies wants all awards, which includes contracts.
Core data: business types, organization structure, fiscal year, financial information and your banking details.
Assertions: your NAICS codes, and optionally Product Service Codes, along with size information.
Representations and certifications: the annual statements about your size, ownership, socioeconomic status and compliance matters. Contracting officers rely on these, and they carry legal weight. Read them; don’t click through them.
Points of contact, as gathered above.

When you submit, the registration goes through checks against IRS records and other systems. A CAGE Code, the five-character code for your entity at its physical location, is assigned as part of this process for US-based entities. You don’t apply for it separately.

Step 4: Confirm the registration is active

Submission is not the finish line. The registration becomes usable only once its status reads Active. Check the status in SAM.gov rather than assuming it went through, and record the UEI, CAGE Code and expiry date somewhere your team will find them. Primes and contracting officers will ask for all three, usually with a deadline attached.

How long it takes

Plan in weeks, not days. The form can be completed in an afternoon by someone with the documents in hand. The variable is entity validation and the external checks that follow: a company whose name, address and tax records agree across every source moves through quickly, and a company with inconsistencies waits while a person reviews its documents.

If you have a specific opportunity in view, start the registration well before the response is due. A registration that isn’t active when you submit a proposal can cost you the award.

Choosing NAICS codes for a software company

NAICS codes determine which searches surface your company and which small-business size standards apply to you. Software companies most often use:

NAICS	Title	Typical fit
513210	Software Publishers	Packaged software and SaaS products
541511	Custom Computer Programming Services	Custom development work
541512	Computer Systems Design Services	Integration and systems design
518210	Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services	Hosting and data processing
541519	Other Computer Related Services	IT services that fit nowhere else

Pick the codes that genuinely describe what you sell, and make one of them your primary. Adding every code that might conceivably apply dilutes your record rather than widening it. Contracting officers searching for a SaaS vendor and seeing a long list of unrelated codes read it as a company without a clear offering.

Size standards differ by code and are set by the SBA. Check the current SBA table for each code you select before asserting small-business status. Your size is determined per code, not once for the whole company.

The mistakes that cost the most time

Registering under a name that doesn’t match your records. The legal name on your incorporation documents, your IRS records and your registration must agree. “Acme Software” on the website and “Acme Software Holdings, Inc.” in the state filing will trigger validation questions.

Paying someone to do it. Registration is free. Third-party firms that charge to file it are legal, but you don’t need them, and some charge a great deal for a form you can complete yourself. The government never charges for registration or for a UEI.

Using a personal email for the points of contact. Renewal reminders go to those addresses. When that person leaves, the reminders stop arriving and the registration lapses without anyone noticing.

Forgetting to renew. Registration expires annually. An expired registration makes you ineligible for award and can drop you out of the searches buyers run. Put the renewal on a calendar sixty days ahead of expiry, and treat the renewal as a chance to re-read your representations rather than re-submit last year’s.

Not knowing your related entities. If your company has subsidiaries or acquired companies that registered separately, each has its own UEI and CAGE Code, and public federal data will treat them as unrelated companies. List them deliberately before a proposal asks.

What registration does and doesn’t do

An active registration means the government knows who you are and can pay you. It is not a qualification, an endorsement or a pipeline. Eligibility for a specific award still depends on your representations being accurate, your size qualifying where a set-aside applies, and whatever compliance a given buyer requires.

It is also the most-read public record of your company in the federal market. Contracting officers doing market research, primes looking for teaming partners and small-business specialists all search it. Treat it as a directory listing buyers read, not a form you file once.

Once you’re registered, the next question is what else a federal buyer will check. Score your company’s federal readiness to see where your registration and identity record stands alongside the other categories buyers look at.
