How do you check a Colombian company and its NIT?
Use the NIT to identify the tax registrant, then check the business-register record and company evidence for the legal entity.

A Colombian NIT is a tax identification number associated with DIAN's Registro Único Tributario (RUT) (opens in a new tab). A NIT printed on an invoice is a starting identifier, not a substitute for matching the company in the Registro Único Empresarial y Social (RUES) (opens in a new tab). Keep the tax and business-register records labelled separately.
A practical two-record check
- Ask for the exact Spanish legal name, NIT and the document that supplied them. Use DIAN's RUT services (opens in a new tab) for the tax-register question.
- Search RUES for the legal business record. Compare its name and registration details with the contract and tax document; check the source and date of every result.
- If the invoice uses a trading name or the company reports a change, request the relevant current registry certificate or filed amendment before concluding that the records refer to the same entity.
For example, a supplier may give a NIT and a shortened brand on an invoice. Match the NIT to its DIAN context, identify the contracted legal company in RUES, and ask for evidence connecting the brand if the names differ. Do not treat a matching tax number as proof of signing authority or beneficial ownership.
Documents and availability
The selected company certificate or filing should answer the particular status, representative or ownership question. If the available record omits current holders, request company-held ownership evidence and later transfer documents.
