If you are a business owner in the United States looking to work with the federal government, apply for grants, or bid on contracts, you’ll need something called a Unique Entity Identifier (UEI). Introduced by the U.S. General Services Administration (GSA) to replace the old D-U-N-S system, the UEI is now the standard identification code for organizations.

In this guide, we’ll break down what a UEI number is, why it matters, and exactly how to obtain one.

What Is a UEI Number?

A UEI (Unique Entity Identifier) is a 12-character alphanumeric code that uniquely identifies your business or organization. It was introduced by the GSA to streamline federal award processes.

Previously, the federal government relied on the D-U-N-S number issued by Dun & Bradstreet. Since April 2022, the UEI is the only recognized identifier for federal awards.

Why Do You Need a UEI Number?

Your organization will need a UEI if you plan to:

• Apply for federal grants through Grants.gov
• Register for federal contracts on SAM.gov
• Receive federal loans or cooperative agreements via agencies like the Small Business Administration (SBA.gov).
• Ensure compliance with the Federal Acquisition Regulation (FAR) available on Acquisition.gov

Without a UEI, your business cannot fully participate in federal programs.

How to Obtain a UEI Number

Here’s a step-by-step guide to getting your UEI:

Step 1: Start With SAM.gov

The UEI is only issued through SAM.gov

managed by the GSA. This system is where all businesses register to compete for federal contracts or grants.

Step 2: Prepare Required Business Information

Before applying, gather:

• Legal business name (must match IRS records).
• Physical street address (required by the U.S. Postal Service (USPS.gov) format).
• Taxpayer Identification Number (TIN) or Employer Identification Number (EIN) from the IRS.gov
• Bank account information for federal payments (required by the U.S. Department of the Treasury Fiscal Service

Step 3: Create a Login.gov Account

To access SAM.gov, you’ll need to create a secure account at Login.gov

• Register your email.
• Set a strong password.
• Enable two-factor authentication, which complies with federal cybersecurity standards from CISA.gov

Step 4: Register Your Entity on SAM.gov

Once logged in:

1. Go to SAM.gov Entity Registration
2. Click Get Started under “Register Your Entity.”
3. Provide your EIN/TIN, business address, and banking details.

Step 5: Receive Your UEI Number

After submission, SAM.gov will automatically generate your UEI number. In most cases, it’s instant.

You can log back into SAM.gov

at any time to view your UEI.

How Long Does It Take?

Most applicants receive their UEI immediately after registering. If verification issues arise (such as mismatched IRS records), processing may take a few business days.

Common Problems & Fixes

1. Business Name Doesn’t Match IRS Records

Verify your name against your IRS EIN Confirmation Letter

2. P.O. Box Issue

SAM.gov requires a physical street address that matches USPS.gov standards.

3. Expired Entity Registration

Even though your UEI doesn’t expire, your SAM.gov registration must be renewed annually. See SAM.gov Renewal FAQs

Updating or Renewing UEI Information

• Annual Renewal: Required on SAM.gov
• Changes to EIN, address, or bank details: Update immediately to avoid payment delays.
• Compliance Reminder: Federal contractors must stay compliant with FAR and DFARS rules via Acquisition.gov
