VIES Uptime Monitor

VIES availability varies significantly by member state. Some countries like Germany and the Netherlands maintain near-perfect uptime, while others experience regular outages due to rate limiting, maintenance windows, or infrastructure issues. This page shows real data from our production traffic so you can see the current state.

Each EU member state operates its own national VAT database. VIES acts as a gateway, routing your request to the relevant national system. Response times depend on each country's infrastructure. Some member states impose rate limits (MS_MAX_CONCURRENT_REQ) that cause additional delays. Vatly mitigates this with automatic retries and caching.

When a member state is unavailable, Vatly returns cached results from the last 25 days (with meta.cached: true) so your application stays functional. If no cached data exists, you receive a clear 503 error with a machine-readable error code. Vatly never silently fails or returns incorrect data.

Vatly uses a multi-layer reliability strategy: automatic retries with exponential backoff, 25-day response caching, per-country circuit breakers, and transparent error reporting. Your integration stays up even when individual member states go down.

This page refreshes every 5 minutes with data from real production traffic through Vatly. The 'recent status' indicator reflects the last 15 minutes of activity. All metrics are calculated from actual upstream calls to VIES and HMRC.

VIES (VAT Information Exchange System) validates VAT numbers for all 27 EU member states plus Northern Ireland. HMRC validates UK VAT numbers separately since Brexit. Vatly provides a single endpoint that automatically routes to the correct service based on the VAT number prefix, so you don't need to integrate both services.
