About DNI (Spain)

What is the Spanish DNI?

The Documento Nacional de Identidad (DNI) is Spain's official identification document, issued by the Dirección General de la Policía. It consists of 8 numeric digits followed by a control letter, in XXXXXXXX-L format.

Control letter algorithm

The control letter is obtained by dividing the 8-digit number by 23 and using the remainder as an index in the table: T, R, W, A, G, M, Y, F, P, D, X, B, N, J, Z, S, Q, V, H, L, C, K, E.

Use in development

Systems targeting the Spanish market — e-commerce, banks, and government platforms — require DNI as mandatory identification. Numbers generated by Help4Dev pass control letter validation and are safe for testing.
