App Description

Spanish Fiscal Identity Number consists of eight digits followed by a check letter for Spanish people with DNI, or a letter, seven digits and a check letter for the rest of individuals.

If we restrict ourselves to DNI, the check letter is one of the following 23 uppercase letters:

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
T R W A G M Y F P D X B N J Z S Q V H L C K E

ABCDEFGHJKLMNPQRSTVWXYZ
That is, all the letters from A to Z except I, O and U. Letters I and O are not used to avoid confusion with the numbers 1 and 0, and U is not used so that the total number of letters is 23, which is a prime number and better suited to calculate the check letter.

If you want to see the NIF letter corresponding to a given DNI, please download the application an enter the number.
