Queation for you experts. Do the DNI numbers for extranjeros have a different format? I am waiting on my DNI card from Migraciones, but the receipt/confirmation they gave me when I left their office has my DNI number. The only problem is that it has 7 digits, unlike my wife's DNI (she is Argentine) which has 8 digits. The number actually shows a dash, followed by 7 digits. Anyone have insight into this?
