Colombia TIN validator
Review the expected Colombia NITstructure before you save it, send it to an API, or include it in a tax workflow. Interactive validation appears only after this country's rules pass authoritative-source verification.
Private by design
Transient validation, no public history
TINs are sent securely to the canonical validation API, processed in real time, and not persistently stored by the public checker.
How Colombia tax IDs are formatted
In Colombia, the tax identifier is commonly known as NIT (NIT). The expected format is Private: cédula-based NIT with DIAN check digit. Entity: 9 digits (800–999M) plus check digit.. Teams usually need a Colombia NIT check around tax filing, financial reporting, business registration, or before a record moves into billing, onboarding, or compliance review.

How to check a Colombia NIT
Use this check before a record reaches billing, tax reporting, or manual review.
Enter the NIT
Paste or type the Colombia tax identifier exactly as it appears in your source record. Spaces and separators are fine when they are part of the expected format.
Review the format result
Check whether the number matches the Colombia syntax currently implemented here. The result does not query a tax-authority registry or confirm ownership.
Confirm important records
For onboarding, tax reporting, or compliance work, treat the result as a data-quality signal and confirm high-risk records with OECD or your internal process.
