About NIE (Spain)

What is NIE?

The NIE (Número de Identidad de Extranjero) is the tax identification number for foreign residents in Spain. Format: L-XXXXXXX-C, where L is a letter (X, Y, or Z) and C is a control letter calculated by the same algorithm as the DNI.

Verification algorithm

The initial letter (X, Y, Z) is replaced by a number (0, 1, 2 respectively), forming an 8-digit number. The control letter is calculated by the same DNI method: division by 23 and letter table lookup.

Use in development

Platforms serving foreigners in Spain — banks, real estate, government services — need to validate NIE. The generator creates fictitious numbers with correct control letters for testing.
