Understanding SAM.gov and Why Registration Matters
Pre-Registration Preparation
- Legal business name exactly as registered with the IRS: Your SAM.gov registration name must match IRS records precisely. Obtain your official name from recent IRS correspondence or tax documents.
- Employer Identification Number or Social Security Number: The TIN used depends on your business structure. Have documentation showing your TIN ready for the registration process.
- Physical business address: SAM.gov requires a physical street address where your business operates. Post office boxes are not acceptable as your physical address.
- Mailing address if different from physical address: You may provide a separate mailing address for correspondence if needed.
- Banking information for electronic funds transfer: Federal payments are made electronically. You need your bank routing number, account number, and bank contact information.
- NAICS codes relevant to your business: Identify the North American Industry Classification System codes that describe your business activities and products or services.
- Login.gov credentials: SAM.gov uses Login.gov for authentication. Create a Login.gov account before attempting SAM.gov registration if you do not have one.
- Business point of contact information: You need names, phone numbers, and email addresses for various points of contact required during registration.
Step-by-Step Registration Process
- 1Create Login.gov account
Navigate to Login.gov and create an account using your email address. Complete identity verification as required. Login.gov provides secure access to multiple government systems including SAM.gov. Use an email address you monitor regularly as important notifications will come through this account.
- 2Access SAM.gov entity registration
Go to SAM.gov and sign in with your Login.gov credentials. Navigate to Entity Registration and select the option to register a new entity. The system will guide you through the registration workflow with clear step indicators showing your progress.
- 3Request Unique Entity Identifier
The first step in entity registration is requesting your UEI. Enter your legal business name and physical address exactly as they appear in official records. The system validates this information against authoritative sources. If validation succeeds, your UEI is assigned immediately. If validation fails, you will need to resolve discrepancies.
- 4Complete core data section
Enter detailed information about your business including business type, organization structure, congressional district, and start date. This section establishes the basic profile of your entity in federal systems. Answer all questions accurately based on your actual business structure and circumstances.
- 5Enter NAICS codes and business descriptions
Select NAICS codes representing your business activities. You may select multiple codes reflecting different products or services you offer. Provide business descriptions helping government buyers understand what you do. Well-written descriptions improve your visibility in vendor searches.
- 6Provide points of contact
Enter contact information for required roles including electronic business point of contact, government business point of contact, and others as applicable. These contacts receive official communications and must be individuals authorized to act on behalf of your business.
- 7Complete representations and certifications
Answer questions establishing your business certifications and eligibility status. These include small business representations, socioeconomic certifications, and various compliance certifications required by federal regulation. Answer truthfully as false certifications create serious legal liability.
- 8Enter financial information
Provide banking information for electronic funds transfer. Enter your bank name, routing number, account number, and account type. This information enables payment on federal contracts. Verify accuracy carefully as errors cause payment problems.
- 9Review and submit registration
Review all entered information for accuracy and completeness before submission. The system provides summary screens for each section. Correct any errors before submitting. Once submitted, your registration enters the validation and processing queue.

Representations and Certifications Deep Dive
- Small business size status: You represent whether your business qualifies as small under SBA size standards for each NAICS code you select. Size determination considers revenue or employees depending on the NAICS code. Certifying as small when you are not creates serious legal consequences.
- Socioeconomic certifications: You may represent status as woman-owned, veteran-owned, service-disabled veteran-owned, or other socioeconomic categories if you qualify. Some certifications require third-party verification while others are self-certified.
- Organizational information: You certify information about your business structure, ownership, and affiliations. This information affects size determinations and eligibility for various programs.
- Tax compliance: You represent compliance with federal tax obligations. Contractors with federal tax delinquencies may face restrictions on contract awards.
- Debarment and suspension: You certify that you are not currently debarred, suspended, or proposed for debarment from federal contracting.
- Various compliance certifications: You certify compliance with requirements including lobbying restrictions, drug-free workplace requirements, and other applicable regulations.
Post-Registration Requirements
Common Registration Problems and Solutions
- Name validation failure: Your legal business name must exactly match IRS records. If validation fails, verify your name with recent IRS documents. You may need to update IRS records before registration can succeed.
- Address validation failure: Physical addresses must be complete and match postal service records. Ensure proper formatting including apartment or suite numbers. New addresses may not yet appear in validation databases.
- TIN verification failure: Your taxpayer identification number must match the legal name you entered. If your business name changed, IRS records may still reflect the old name until updated.
- Administrator access problems: Only designated administrators can modify registrations. If your administrator leaves the organization, you need to complete administrator reassignment procedures.
- Login.gov issues: Account lockouts or identity verification problems at Login.gov prevent SAM.gov access. Contact Login.gov support for authentication issues separate from SAM.gov registration problems.
