NIE Validation (Spain)

What does the validator check?

Checks if the NIE control letter is correct, replacing the initial letter (X=0, Y=1, Z=2) and applying the same DNI algorithm (division by 23).

When is it considered invalid?

When it doesn't start with X, Y, or Z, doesn't have the correct length, or the control letter doesn't match the calculation.

Use in development

Systems serving foreigners in Spain need to validate NIE. The validator helps test implementations.
