Colombia Legal Invoicer Verification

Verifik's Legal Invoicer Verification API helps you validate whether a Colombian company has a legal invoicer registered in DIAN (Dirección de Impuestos y Aduanas Nacionales). It's designed to streamline your KYB (Know Your Business) processes, prevent fraud, and ensure you meet all regulatory requirements effortlessly.

We built this integration for businesses that need a fast, secure, and automated way to confirm the invoicer registration status of Colombian companies, partners, or vendors.

What does this API validate?

Our API connects directly with official DIAN records to validate:

• Company NIT & electronic invoicing (facturación electrónica) registration: Supports Número de Identificación Tributaria (NIT).
• Invoicer contact: Returns the registered invoicer email and related fields when DIAN exposes them.
• Registration check: Confirms that the entity appears in DIAN’s legal invoicer dataset for electronic invoicing (distinct from general taxpayer status — see Colombia DIAN Verification).

By verifying these details, you can be confident that the company you're dealing with has proper invoicing capabilities and is compliant with DIAN requirements, significantly lowering the risk of fraud and ensuring compliance.

Notes

• GET query only — no body. Use Accept (not Content-Type) for JSON responses.
• This route returns legal invoicer / e-invoicing registration data (e.g. email when available). For general taxpayer status and obligations, use Colombia DIAN Verification (GET /v2/co/company/dian).
• 404 may occur when DIAN does not return invoicer email for that NIT (see integration logic).
