Does this tool verify a check digit?

No, and that is deliberate. SIN does not publish a universal public check-digit algorithm for the current NIT format, so the honest validation is structural — digits only, the correct length band, and no leading zero. Any tool claiming a NIT check digit for the modern format is inventing one.

How long is a Bolivian NIT?

It varies. Natural-person NITs are frequently the 7 to 8 digit CI (cédula) number, while entities can have longer assigned numbers. This tool accepts 7 to 12 digits, which covers the common issued range.

Does a valid format mean the taxpayer is registered?

No. A valid format only means the NIT is well-formed. It does not confirm the taxpayer is registered or active. Confirm status through the SIN online padrón before issuing electronic invoices.

Why does my NIT fail?

Common reasons are non-numeric characters, a leading zero (issued NITs do not start with 0), or a length outside the 7 to 12 digit band. The message tells you which rule was broken.

Is my NIT sent anywhere?

No. The format check runs entirely in your browser. Nothing is uploaded, logged, or stored, so it is safe for validating supplier and customer records.

Bolivia NIT Validator

The NIT (Número de Identificación Tributaria) is the tax identifier issued by Bolivia’s SIN (Servicio de Impuestos Nacionales). Since the migration to the biometric padrón, the NIT is effectively the taxpayer’s CI number for natural persons or an assigned number for entities. This free validator checks the NIT’s structural format honestly, without fabricating a check digit.

How it works

There is no published, universal public check-digit algorithm for the current Bolivian NIT, so the meaningful validation is structural. The tool:

Strips grouping spaces, dots, and dashes.
Confirms the value is digits only — any letter or symbol fails.
Rejects a leading zero, since issued NITs do not start with 0.
Confirms the length is within the issued band (7 to 12 digits).

It also indicates the likely taxpayer type: shorter NITs (7-8 digits) are typically natural persons whose NIT is their CI, while longer numbers are usually entities. This is informational, not a strict rule.

Notes and honesty

Some online checkers assert a modulo-11 check digit for the Bolivian NIT. For the current SIN format that algorithm is not officially published, so asserting it would produce false negatives on perfectly valid numbers. This tool therefore reports a format pass, not a check-digit verification — the correct, honest answer.

A format pass means the NIT is well-formed; it does not confirm the taxpayer is registered or active. For invoicing under Bolivia’s electronic billing system, confirm the taxpayer status via the SIN online padrón. All processing is local, so your NIT never leaves your device.
