How Long Does a National Insurance Number Take?

Standard applications for a National Insurance number typically take 2 to 4 weeks after you complete your identity verification. The process involves several steps, and the actual timeline depends on a few factors.

Several factors can affect how quickly you get your NI number:

• Identity verification: The GOV.UK ID Check app process usually takes 10-20 minutes. Delays here can slow everything down.
• Application accuracy: Errors or missing information can cause HMRC to query your application.
• Time of year: HMRC may be busier at certain times, particularly during peak hiring seasons.
• Your immigration status: Some statuses require additional checks.

The most important step after submitting your application is verifying your identity using the GOV.UK ID Check app. This is a secure app that scans your passport or biometric residence permit and takes a photo of you. The faster you do this, the faster HMRC can process your application.

Once you've verified your identity, we submit your application to HMRC, and your NI number letter is typically dispatched within 2-4 weeks.

• Complete the GOV.UK ID Check app immediately after submitting your application
• Ensure your name matches your passport exactly
• Provide a correct UK postal address — your NI number is sent by post
