An individual's NIF is personal data. This page keeps nothing and sends nothing, and it has no ads, but do not check other people's numbers without a reason.

Portugal

Nine digits, the last being a check digit. For individuals, Decree-Law 14/2013, article 4, says the first digit runs from 1 to 4, and that the initial digits 45 are for non-residents with only income taxed by final withholding.

Spain

Nine characters. Individuals: 8 digits and a letter; foreigners (NIE): X, Y or Z, 7 digits and a letter. The Ministry of the Interior gives the rule: divide the number by 23 and look up the letter, as in its example 12345678Z. For a NIE, X counts as 0, Y as 1, Z as 2. Companies: a letter for the legal form, 7 digits and a check character, under Order EHA/451/2008.
