DUNS vs UEI: What Changed and Why It Matters
If your manufacturing company has ever applied for government contracts or grants, you've probably heard of DUNS numbers or UEI. But with recent updates from the federal government, there's been a shift from DUNS to UEI identifiers. Understanding what changed, why it matters, and how it impacts your business is essential. Let’s break it down in simple terms.
What Is a DUNS Number?
A Dun & Bradstreet (D&B) Data Universal Numbering System (DUNS) number has been around for decades. It's a unique nine-digit identifier assigned to every business entity. When you wanted to work with the government or big corporations, having a DUNS number was often a requirement.
Think of the DUNS as your company’s unique social security number—used to verify your identity and creditworthiness. It’s helpful for building business credit and showing your company's legitimacy on official records.
What Is a UEI?
The Unique Entity ID (UEI) is a newer identifier introduced by the U.S. federal government. It’s a 12-character alphanumeric code that serves the same purpose as the DUNS, but with some important differences.
> Why the change? The federal government decided to move away from DUNS to streamline processes, reduce costs, and improve data accuracy. The UEI is issued directly through the System for Award Management (SAM), which is the federal system for federal grants and contracts.
Key Differences Between DUNS and UEI
Feature | DUNS | UEI |
|---|---|---|
Issuer | Dun & Bradstreet | Federal government’s SAM system |
Format | 9 digits | 12 characters, alphanumeric |
Availability | Required by many companies and agencies | Mandatory for federal grants and contracts |
Cost | Often free, but some D&B services charge fees | Free |
Integration | Stand-alone, outside of federal systems | Embedded within SAM.gov |
What Changed?
The federal government now requires new entities registering for federal awards to generate a UEI instead of obtaining or maintaining a DUNS number.
If your company already has a DUNS, you don’t need to get a new one. Your DUNS remains valid for most purposes outside of federal awards.
All new registrations or re-registrations in SAM.gov will use the UEI as your primary ID.
The transition was completed by April 2022 for most federal processes.
Why Does This Matter for Small and Mid-Sized Manufacturers?
Simplified and Cost-Effective
The switch to UEI reduces the number of identifiers you need to manage. Plus, obtaining a UEI is free—no expensive credit checks or third-party services required.
Streamlined Federal Applications
If you work with federal agencies, your company’s UEI is now the key number for grants, contracts, and reporting. This can make applying faster and less complicated.
Better Data Accuracy
The federal system now maintains its own identifiers, reducing errors and outdated info tied to DUNS numbers. This means more reliable data about your company in government databases.
What Should You Do?
If you don’t have a UEI yet: Register your company in SAM.gov to obtain a UEI. It takes just a few minutes and is free.
If you already have a DUNS: You’re still good for most purposes, but ensure your SAM registration is updated with your UEI when applying for federal funds.
Keep your SAM registration current: The federal government requires your company to keep your SAM profile active to continue receiving awards and grants.

In Summary
The move from DUNS to UEI is part of the federal government’s effort to make doing business easier and more efficient. Small and mid-sized manufacturers engaging with federal agencies should get familiar with the UEI — it’s now the primary way to identify your company in federal transactions.
Understanding these changes helps you stay compliant, avoid delays, and maintain your opportunities to work with the government. Keep your registration current, and don’t hesitate to reach out if you need help navigating the new system.
