What Is a National Insurance Number?
A National Insurance Number (NIN) is a unique identifier assigned to individuals in the UK. It helps track tax contributions, benefits, and state pension eligibility. Every resident who works or claims benefits needs a National Insurance Number to ensure accurate records of their financial contributions.
The format of a National Insurance Number is two letters, six digits, and a final letter (e.g., AB123456C). This number is personal and remains the same throughout an individual’s life. It is used by HM Revenue and Customs (HMRC) and the Department for Work and Pensions (DWP) for administrative purposes.

A National Insurance Number (NIN) is a unique identifier used in the United Kingdom to track an individual’s contributions to the National Insurance system. It is essential for anyone working or claiming benefits in the UK. The format of the National Insurance Number follows a specific structure to ensure consistency and ease of verification.
The standard format of a National Insurance Number is two prefix letters, six numeric digits, and one suffix letter, displayed in the following way: AB123456C.
- Prefix Letters: The first two characters are always letters. These letters are assigned randomly but adhere to specific rules. For example, the letters D, F, I, Q, U, and V are never used in the prefix.
- Numeric Digits: The six digits following the prefix are numeric. These digits serve as the primary identification component, ensuring uniqueness for each individual.
- Suffix Letter: The final character is a single letter, either A, B, C, or D. This suffix does not directly affect the identification but helps with administrative classifications.
