About this tool

This checklist covers common official steps for looking up an EU VAT number, deciding whether you need to register, and using OSS or IOSS. It is not a VAT-number registry and does not replace VIES (https://ec.europa.eu/taxation_customs/vies) or a national tax authority. Register for OSS or IOSS at the official portal https://vat-one-stop-shop.ec.europa.eu/. Thresholds, documents and filing cycles follow Your Europe and the competent authority; this page does not invent unverified threshold amounts.

How the formula works

This page is a process checklist, not a calculator. Follow the official sequence: confirm the transaction takes place in the EU, whether registration is required, apply or join OSS / IOSS through official channels, and check a counterparty’s VAT number in VIES where applicable.

FAQ

Can I check whether a VAT number is valid here?

No. Use the official EU VIES system at https://ec.europa.eu/taxation_customs/vies. This page does not connect to the official database or store VAT numbers.

What is the difference between OSS and IOSS?

OSS (One-Stop Shop) mainly covers certain intra-Union distance sales. IOSS (Import One-Stop Shop) covers low-value goods imported into the EU. The official scope is on https://vat-one-stop-shop.ec.europa.eu/.

What is the registration threshold?

Thresholds depend on the type of supply and national rules, and they can change. Use the current figures on Your Europe and the competent authority, not an undated reprint.
