English, Welsh and Scottish driving licence numbers contain information about the applicant's name, sex and date of birth. This information is written in a special format but can be gleaned and matched against the information provided by the applicant in Section A.
Please note that the date of birth on English, Welsh and Scottish driving licences, issued before1977, is not recorded as a separate entry on the licence.
The date of birth can be deciphered from the driving licence number and checked against the date of birth field on the application form.
For example the format of the number for Christine Josephine Robinson, born 2 July 1975
R O B I N 7 5 7 0 2 5 C J 9 9 9 0 1
N N N N N Y M M D D Y I I C C C C C
* N = 1st five letters of the surname (if the surname begins MAC or MC it is treated as MC for all).
* Y = YEAR of birth.
* M = MONTH of birth (In the case of a female, the number represented by the first M will have the value 5 added to the first digit e.g. a female born in November (i.e. 11) would display '61' in the MM boxes or if born in February (i.e. 02) would display "52").
* D = DAY of month of birth.
* I = Initial letter of the first two forenames - if only one, then 9 will replace the second letter. If the licence indicates that the applicant has a middle name, ensure that one has been provided in Section A.
* C = Computer generated.
Please note, for Northern Ireland; Isle of Man and Jersey driving licences the licence number is in a different format. The licence number is unique to the driver and the "name" or "date of birth" validation, as shown above, cannot be used.
