The shift from DUNS to UEI Numbers has introduced key differences and implications. Businesses need to understand these changes for federal contracting and grants.
In April 2022, the system for award management (SAM.gov) made a big change. It replaced DUNS numbers with something new called UEI numbers. This was part of an effort to make things simpler and more direct.
Every business that already had a DUNS number from Dun & Bradstreet got a UEI number given to them automatically. This switch helps in making business dealings with the federal government smoother.
The move from DUNS to UEI makes dealing with the federal sector easier for businesses.
By using UEI numbers, small business owners now have a clear path when working on federal contracts or grants. The idea was not just to change names but to improve how companies are seen and managed within federal systems like acquiring loans or taking part in auctions under Federal Acquisition Regulation rules.
Now, services like checking your entity’s status or updating sensitive information through SAM.gov require your unique identifier: your UEI number.
The move from DUNS numbers to UEI marks a big change. Now, every business working with the federal government needs a unique entity identifier (UEI), not just the data universal numbering system (DUNE) number they might have had before.
This switch means that instead of going through a credit bureau for identification, companies register directly on SAM.gov. It simplifies things since one central spot handles it all.
This update affects how small businesses handle federal contracting and grants. The old system relied on third-party credit reporting agencies and could get complicated. With UEI numbers coming directly from SAM.gov, there’s less confusion and more direct control over your company’s information.
This ensures clarity in governance and helps meet Office of Management and Budget standards without mixing up with employer identification numbers or social security numbers used for other tax purposes.

UEI numbers play a crucial role in federal contracting and grants. They enhance transparency and efficiency, allowing small business owners to access opportunities for growth and support.
For small business owners like us aiming to work with the government, having a UEI number is crucial. It serves as your ticket into federal contracting and grants. This unique identifier is now mandatory for all entities before they can apply for federal funds or contracts.
With it, the government tracks how they distribute their money to ensure everything runs smoothly and fairly.
This system boosts transparency in how funds are allocated and used. We all want our businesses to grow, right? By getting involved in projects funded by the government, we find new opportunities to expand.
But first, we need that UEI number. Once you have it, you’re ready to compete for contracts and win grants that could take your business to new heights.
Next up, let’s look at enhancing transparency and efficiency through this process.
UEI numbers help us show the world our business is clear and direct. This number means we can work with the federal government without confusion. Our dealings become open for everyone to see.
This openness helps our small business grow trust with big partners like government agencies and other companies.
Getting a UEi number makes signing up for federal projects faster. We fill out less paperwork and spend more time doing what we love—running our business. The Federal Service Desk (FSD) keeps track of all our questions about UEI or SAM.gov, making sure we stay on track.
Next, let’s look at how to get your very own UEI number.



Get a UEI number by registering on SAM.gov and providing necessary documents. Follow the steps for registration and ensure you have the required documentation.
To start getting your UEI number, first, you need to visit SAM.gov. Here, creating a Login.gov account is the initial step. You will fill out your basic information such as name and email address.
After setting up a strong password, you’ll move on to completing your user profile. This includes details like your federal tax IDs and mailing address with zip code.
Next, follow SAM.gov’s guide to finish registering your business or entity. They ask for more detailed info about your small business. Make sure all data is accurate so there are no delays in getting your UEI number.
Streamlining processes makes obtaining a UEi number through SAM.gov efficient for small businesses.
Keep in mind that updating this info is crucial if things change with your business status or contact details. Always log in with your credentials at gsa.gov to manage or renew your information well before it expires to stay active in federal contracting and grants opportunities.
To get your UEI number, you’ll need some important papers. First, make sure you have your business’s legal name, address, and contact details ready. These are crucial for identifying your company correctly.
You also need to know how many people work for you as this information is required too.
If the person running your account isn’t known, a notarized letter is necessary. This step ensures everything is official and ties back to making the process smoother for per diem rates discussions later on.
Getting all these documents together before you start makes things much faster and easier.



1. Check your entity status to ensure compliance and eligibility.
2. Keep your UEI updated through the renewal process as required by SAM.gov registration.
We often check our entity’s status on SAM.gov under “Workspace.” This step shows if everything is up to date or if we need to fix something. If there are pending FSD ticket updates, we get an email.
We can also call the FSD Help Desk for help if things seem confusing.
Next, let’s talk about how to keep our UEI number current with renewal and update procedures.
After checking your entity’s status, it’s time to focus on keeping your SAM.gov registration current. Our team guides you through the renewal process, which must happen every year.
Keeping your registration active is crucial for federal contracting and grants. The entity administrator has a key role here. They must actively submit the renewal through SAM.gov.
To stay ahead in federal opportunities, annual recertification is a step none of us can skip.
Documents ready and details up-to-date make this process smoother. This yearly recertification ensures your business keeps its edge in government contracting and funding opportunities.
