NHS Number

The NHS number is a unique number used by the National Health Service in England, Wales and the Isle of Man to identify patients. Scotland's equivalent is called a CHI number.

The NHS number was introduced in 1996 replacing a previous system. It is a ten digit number in a 3-3-4 format with the final digit being a check digit. Examples given are 943-476-5919 and 943-476-5870. Currently issued numbers are in two ranges from 400-000-000 to 499-999-999 and 600-000-000 to 708-800-001.

A person gets an NHS number at birth, or when they first make contact with the NHS by registering with a GP. It comes from a record being made on the Personal Demographics Service, a national patient database.

Famous quotes containing the word number:

    I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.
    Carolyn Wells (1862–1942)
