About official service availability
The verification services monitored here are operated by government bodies and international organisations. They are generally highly available but experience occasional planned and unplanned outages.
- VIES occasionally has individual member state connections go offline while the main interface remains accessible. If a specific country's VAT cannot be verified, the member state's national tax authority website is often the alternative.
- EORI validation is linked to the European Commission's DDS2 (Data Dissemination Service 2) customs platform, which is periodically maintained.
- GLEIF maintains a highly available public API. LEI data is also accessible through multiple commercial data providers as an alternative.
- HMRC APIs are subject to scheduled maintenance windows, which HMRC announces on their developer hub and status page.
