Informal and comprehensive human-readable definition of a concept. Description	The National Health Service (NHS) Number in the UK is a unique identifier used within the NHS to identify individuals for health records and services. The NHS Number is used across the UK’s healthcare system to accurately link patients to their health records, enabling continuity of care. It is typically issued upon first registration with a GP or another NHS service. It is a ten-digit number issued to everyone registered with the NHS, and it follows a specific format with a check digit to ensure accuracy. The NHS Number has the following structure: Ten digits, written in the format 123 456 7890. Digits 1–9: The first nine digits are a unique sequence. Digit 10: The last digit is a check digit, calculated using a weighted modulus 11 algorithm on the first nine digits. The check digit (last digit) is calculated using a weighted system, where each of the first nine digits is multiplied by a specific weight (from 10 down to 2). The sum of these products is divided by 11, and the remainder is subtracted from 11 to produce the check digit. If the result is 10, the NHS number is invalid.
