SAM.gov registration is not optional for federal contractors. It is a legal prerequisite. Without an active registration in the System for Award Management, you cannot receive a federal contract award, cannot be paid on existing contracts, and cannot access most federal procurement portals. For SDVOSB firms, an active SAM.gov registration is the foundation on which every other certification and contracting activity rests.

This guide walks through the complete SAM.gov registration process, the renewal requirements that catch too many firms off guard, and the ongoing maintenance that keeps your registration in good standing.

What SAM.gov actually is

SAM.gov is the federal government's primary database for businesses that want to do business with the government. It consolidates what used to be several separate systems, including the Central Contractor Registration (CCR), the Online Representations and Certifications Application (ORCA), and the Excluded Parties List System (EPLS), into a single platform managed by the General Services Administration.

When a contracting officer wants to verify that your firm is eligible to receive a contract, SAM.gov is where they look. When a payment officer needs to process an invoice, your banking information in SAM.gov is the source of record. When the SBA wants to verify your SDVOSB certification status, they cross-reference your SAM.gov registration. The database is central to the entire federal contracting lifecycle.

Before you register: what you need

Gather the following before you begin the registration process. Starting without these materials adds time and increases the chance of errors in your record.

Unique Entity Identifier (UEI). SAM.gov now issues UEIs directly during registration. If your business was registered before April 2022, you already have a UEI (it replaced the DUNS number). If you are registering for the first time, your UEI is assigned automatically when you create your entity record.

Taxpayer Identification Number (TIN). This is your Employer Identification Number (EIN) for businesses, or your Social Security Number for sole proprietors. The IRS verifies your TIN and legal business name during registration, so both must match exactly what is on file with the IRS. A mismatch is one of the most common causes of registration delays.

CAGE Code. If your firm has done business with the federal government before, you may already have a Commercial and Government Entity (CAGE) code. If not, one is assigned during the SAM.gov registration process. The CAGE code is used across the defense and civilian procurement communities as a unique identifier.

Bank account information. SAM.gov stores your Electronic Funds Transfer (EFT) information for direct deposit of contract payments. Have your bank's routing number and your account number ready.

NAICS codes. Identify the North American Industry Classification System codes that best describe your business activities. You will designate a primary NAICS code and can add additional codes. These codes determine which size standard applies to your business and which contracts you are eligible to bid on.

Step-by-step registration process

Step 1: Create a Login.gov account. SAM.gov uses Login.gov for identity verification. Go to login.gov and create an account with a government email address if possible, or any professional email address. You will need to verify your identity through multi-factor authentication.

Step 2: Navigate to SAM.gov and start a new entity registration. Go to sam.gov, sign in with your Login.gov credentials, and select "Register an Entity." Choose "U.S. Entity" for domestic businesses.

Step 3: Enter your legal business name and TIN. Enter your exact legal business name as it appears in IRS records. Enter your EIN. SAM.gov will initiate an IRS TIN match. This verification can take 2 to 5 business days. Do not attempt to move forward with mismatched information.

Step 4: Complete core data. Enter your physical address, mailing address (if different), CAGE code (or request a new one), business start date, fiscal year end date, and congressional district. Accuracy here matters because this information appears on government contract records.

Step 5: Complete assertions. The assertions section captures your business type, ownership information, NAICS codes, goods and services description, and size classification. This is where you assert your small business status and any certifications you hold. For SDVOSB firms, you will assert your veteran-owned and service-disabled veteran-owned status here.

Step 6: Complete representations and certifications. The reps and certs section is an extensive set of compliance certifications required under various federal regulations. Most fields are pre-populated with standard responses, but review each one carefully. These are legal representations, and incorrect certifications can have serious consequences.

Step 7: Add Electronic Funds Transfer information. Enter your bank routing and account numbers for direct deposit of payments. This information is encrypted and is only used for payment processing.

Step 8: Submit and wait for activation. After submission, SAM.gov processes your registration. For new registrations, activation typically takes 7 to 10 business days. During this time, SAM.gov verifies your TIN with the IRS, processes any CAGE code assignments, and validates your registration data.

Annual renewal requirements

SAM.gov registrations expire annually. Your registration is active for exactly 365 days from the date of activation or last renewal. This is the detail that creates the most problems for otherwise compliant firms.

The consequences of a lapsed registration are immediate and severe. You cannot receive new contract awards. You may not be able to submit proposals on active solicitations. Your payment processing may be interrupted on existing contracts. And your SDVOSB certification status may be flagged as unverifiable. As described in the companion article on registration lapses, these problems are entirely avoidable with a simple calendar reminder.

Renewing is significantly simpler than the initial registration. Log into SAM.gov, navigate to your entity record, review all information for accuracy, update anything that has changed (particularly address, bank account, and business information), and submit the renewal. The renewal takes effect immediately and extends your registration for another 365 days.

Best practice is to renew 30 to 45 days before expiration. This gives you buffer time if any verification issues arise. SAM.gov sends email reminders 60, 30, and 15 days before expiration, but deliverability is not guaranteed. Set your own reminders regardless.

Maintaining your registration between renewals

An annual renewal does not excuse you from keeping your registration accurate throughout the year. Federal regulations require you to update your SAM.gov record within 30 days of any change to the information contained in it. Material changes include changes to your legal business name, address, ownership, banking information, NAICS codes, and size classification.

For SDVOSB firms, ownership changes are particularly critical. Any change to the veteran's ownership percentage, the nature of the service-connected disability, or the veteran's control over daily operations must be reflected in both SAM.gov and your SBA certification record.

Common registration problems and how to avoid them

TIN mismatch. The legal business name in SAM.gov must match the name on file with the IRS exactly. Even minor differences in punctuation, spacing, or abbreviation can cause verification failures. Check your IRS correspondence for your exact registered name.

Expired MPIN. SAM.gov requires a Marketing Partner Identification Number (MPIN) as a security credential. If your MPIN is forgotten or inaccessible, recovering it requires identity verification through Login.gov and can take several days.

Incorrect size classification. SBA size standards are updated periodically. Review the applicable standard for your primary NAICS code each time you renew. An incorrect size classification in SAM.gov can affect your eligibility for set-aside competitions.

Stale banking information. If you change banks or accounts, update SAM.gov immediately. A payment sent to a closed account is recovered by the government and reissued, but the process is slow and administratively burdensome for both parties.

SAM.gov and SDVOSB certification

Your SAM.gov registration and your SDVOSB certification through the SBA are separate records that must remain consistent. The SBA uses SAM.gov data to verify firm identity and registration status during the certification and recertification process. If your SAM.gov record shows a lapsed registration or a business type that conflicts with your certification claims, your certification review will be delayed.

When you update your SAM.gov record, review your SBA certification data at the same time. Ensure that the legal business name, address, UEI, and ownership information are consistent across both systems.

Next steps

SAM.gov registration is the starting point, not the endpoint. Once registered, the next steps are obtaining your SDVOSB certification through the SBA, identifying your target NAICS codes and the set-aside opportunities available in those industries, and building the contract history that makes your firm competitive. VetBid's Scout feed surfaces SDVOSB set-aside opportunities from SAM.gov matched to your registered NAICS codes, so your registration is directly connected to the opportunities you see.
