A closer look at UTR numbers
Find out the fastest way to get your UTR number and how long your UTR number lasts once it’s activated.
How long does it take to get a UTR number?
This depends on how you apply for your UTR number. The quickest way to get your UTR number is usually by applying online. This is because postal and phone entries may require additional requests from HMRC for information.
Once HMRC has all of the information they need, you’ll receive your UTR number by post within 10 days. If you’re abroad, your UTR number can take up to 21 days to arrive. Activation codes usually follow a week to 10 days after.
Do you always have the same UTR number?
Yes, your UTR number stays the same and cannot be changed after it has been issued. This is to allow HMRC to track all tax payments and bills you are responsible for. If you de-register for self-employment and then register again at a later date, HMRC will provide you with the same UTR number.
