Frequently Asked Questions
What is the Andorra NRT?
The NRT (Número de Registre Tributari) is the official tax identification number issued by Andorra's Department of Taxes and Borders (Departament de Tributs i de Fronteres) to all taxpayers — individuals and legal entities alike. It is required for opening bank accounts, filing taxes, and conducting regulated business in Andorra. Use Lookuptax to validate any NRT instantly without manually querying government registries.
Is NRT validation mandatory for invoices?
Yes. Andorran regulations require the NRT to appear on all commercial invoices, contracts, and official correspondence. Issuing an invoice with an incorrect or invalid NRT can lead to penalties and rejected deductions. Lookuptax lets you validate NRTs in bulk before your invoicing cycle, keeping you compliant automatically.
What data is returned when I validate an NRT?
A successful validation confirms the NRT format integrity and, where registry data is available, returns the registered entity name, address, registration status, and entity type. This is particularly useful for KYC workflows and supplier onboarding. Sign up at Lookuptax to access the full structured response via API.
