What is a UEI number?

The UEI, or Unique Entity Identifier, is a number that acts as a de facto social security number for your business. Getting the UEI is one of the first steps to becoming a GSA contractor, and so it is crucial for you to understand how it works.

Using this unique number, you can become easily searchable and identifiable to the government. If you’ve been in this industry for some time, you may know that this was previously the job of the DUNS number.

What does a UEI do?

Having a UEI number, as mentioned above, is crucial for you to be accessible to the government. It helps to make the process of organization quick and simple, and is also a huge step forward for automation. Since the UEI system is completely operated by the federal government, there is no third-party involved anymore.

This helps eliminate issues and unwanted changes, and aids contractors as well as the government itself. The process for registration is now far less time-consuming, and does not require you to jump from one website to another.

As the transition towards the use of UEI is made, there may be a quick learning period - but the end result is hoped to be far smoother and accessible for all entities involved.
