What do the RIF prefixes mean?

V is a Venezuelan natural person, E is a foreign natural person, J is a company (jurídico), P is passport-based, and G or C indicate government and public entities. Each prefix maps to a numeric weight used in the check-digit calculation.

How is the RIF check digit calculated?

It is a modulo-11 calculation. The prefix value is multiplied by 4, then the eight body digits are multiplied by the weights 3,2,7,6,5,4,3,2. The products are summed, the remainder modulo 11 is taken, and the check digit is 11 minus that remainder, with 10 and 11 collapsing to 0.

Does a valid RIF mean the taxpayer is registered?

No. A valid result confirms the RIF passes the SENIAT check-digit rule and is internally consistent. It does not confirm registration or active status. Check the official SENIAT portal before issuing invoices.

Why does my RIF fail?

A failure usually means a digit was mistyped or transposed, the wrong prefix was used, or the number is not 8 body digits plus a check digit. The tool shows the expected check digit so you can spot a single wrong digit.

Is my RIF sent anywhere?

No. Prefix detection and the modulo-11 maths run entirely in your browser. Nothing is uploaded, so it is safe for validating supplier and customer records in bulk.

Venezuela RIF Validator

The RIF (Registro de Información Fiscal) is Venezuela’s tax identification number issued by SENIAT. It pairs a letter prefix that classifies the taxpayer with an 8-digit number and a single check digit. This free validator confirms the prefix type and verifies the check digit using SENIAT’s modulo-11 rule.

How it works

A RIF looks like J-12345678-9: a letter prefix, eight body digits, and one check digit. The prefix sets a numeric weight, and the rest follows a modulo-11 calculation:

Map the prefix to its value — V = 1, E = 2, J = 3, P = 4, G = 5 (C is treated as a public-entity value).
Multiply the prefix value by 4.
Multiply the eight body digits by the weights 3, 2, 7, 6, 5, 4, 3, 2 and add them to the running sum.
Take sum mod 11 to get a remainder r. The check digit is 11 - r, where a result of 10 or 11 collapses to 0.

The tool shows the prefix meaning, the expected check digit, and the actual one so you can see exactly why a number passed or failed.

Example and notes

Enter J-12345678-9. The tool maps J to 3, computes the weighted sum, takes modulo 11, and compares the derived check digit to the entered 9. If they match, the RIF is internally valid.

A valid result means the RIF is consistent under the SENIAT rule — it does not confirm the taxpayer is registered or active. For invoicing, always confirm status on the official SENIAT portal. All processing is local, so your RIF never leaves your device.
