NHS NUMBER

Change to Data Element: Change to Description

Format/length: n10
HES item: NEWNHSNO
National Codes:
Default Codes:  

Notes:
It is mandatory to record the NHS NUMBER for each PATIENT. The exception to this rule is A&E care. The NHS NUMBER, the primary identifier of a PERSON, is a unique identifier for the PATIENT.It is mandatory to record the new NHS NUMBERS for each PATIENT. Exceptions to this rule are A&E care and babies under six weeks. The new NHS NUMBERS, the primary identifier of a PERSON, is a unique identifier for the PATIENT.

The NHS NUMBERS is 10 numeric digits in length. The tenth digit is a check digit used to confirm its validity. The check digit is validated using the Modulus 11 algorithm and the use of this algorithm is mandatory. There are 5 steps in the validation of the check digit:

Step 1 Multiply each of the first nine digits by a weighting factor as follows:

Digit Position
(starting from the left)
Factor
1 10
2 9
3 8
4 7
5 6
5 6
4 7
3 8
2 9

Step 2 Add the results of each multiplication together.

Step 3 Divide the total by 11 and establish the remainder.

Step 4 Subtract the remainder from 11 to give the check digit.

If the result is 11 then a check digit of 0 is used.
If the result is 10 then the NHS NUMBERS is invalid and not used.

Step 5 Check the remainder matches the check digit. If it does not, the NHS NUMBERS is invalid.
