A National Insurance number is a unique reference number issued by HM Revenue and Customs (HMRC) to UK citizens and residents. It is used to track an individual’s National Insurance contributions and is essential for accessing certain benefits and services, such as the National Health Service (NHS) and state pension.
There are several ways to check your National Insurance number. One way is to look at your National Insurance card. This card is usually issued when you first start working and contains your National Insurance number, as well as other personal information. Another way to check your National Insurance number is to contact HMRC. You can do this by phone, online, or by post.
