NIF/CIF format invalid in Spain

This is the rejection, word for word: „[FACE-001] Spanish tax ID must be valid NIF (individuals) or CIF (companies) format with correct checksum letter. NIF uses 8 digits + letter, CIF uses letter + 7 digits + control character.“

Why this matters in Spain

Spain requires (B2G) e-invoicing using Facturae 3.2.x. An invoice with this error is rejected; it cannot be processed under Spain's rules.

What to have readyThe missing value from your purchase order, contract or bookkeeping.

What we doVerify the NIF/CIF format and checksum letter are correct.
