Vatlayer is a JSON-bases REST API offering free, instant & secure EU VAT number validation, VAT compliant price calculations and accurate VAT rates for all 28 EU member states. Its system is secured by HTTPS and focused on ease of use & integration, delivering all EU VAT data in lightweight and highly portable JSON format.

At vatlayer we aim to provide the highest possible level of data accuracy and response speed possible. In order to achieve this for every API request, our VAT information API relies on multiple servers and a distinct “fallback & validation” mechanism, consisting of a fairly large number of different data sources, which include the European Commission’s databases.
