What's the difference between a Spanish CIF and NIF number?
When sending parcels to Spain, or importing parcels from Spain, your customs declaration should include the correct ID numbers in addition to the EORI number.
Depending on the type of recipient or exporter in Spain, you will need to supply a CIF or NIF.
CIF is the tax ID number that identifies a company or legal entity in Spain.
NIF is the Spanish ID number, which can have two different forms:
If you are a Spanish national, it is called DNI. Then it will made up of 8 letters and a number.
Foreign nationals will need to use their NIE, made up of 8 numbers and a letter (which can only be X,Y, or Z).
Both of these two numbers are issued by the Interior Ministry in Spain.
