RIF
Registro de Información Fiscal: Venezuela's tax identifier consisting of a letter (J/V/E/G/P) and 9 digits + check digit.
The RIF (Registro de Información Fiscal) is Venezuela's tax identifier, issued by SENIAT (Servicio Nacional Integrado de Administración Aduanera y Tributaria). It's mandatory for every taxpayer — natural persons, legal entities, public bodies. Structure: an initial letter indicating type, followed by 9 digits and a check digit. Example: `J-12345678-9`. Valid prefixes: - `V`: Venezuelan natural person. - `E`: resident foreigner. - `J`: legal entity (company). - `G`: government body. - `P`: passport (non-resident foreigner). The check digit is computed with a custom modulo 11 that assigns a weight to the prefix (`V`=1, `E`=2, `J`=3, `P`=4, `G`=5) plus weights `3, 2, 7, 6, 5, 4, 3, 2` over the first 8 digits. Formula: `11 - (weighted_sum mod 11)`, with 0 if the result is 10 or 11. For natural persons, a V or E RIF is usually built from the Cédula de Identidad by appending the check digit. Normadata validates prefix, charset, length, and check digit. Verifying existence requires querying the SENIAT portal.
