How to protect your checkout against VIES downtime
1. Never block checkout on MS_UNAVAILABLE
National database downtime does not mean the buyer's VAT ID is invalid. Blocking the purchase causes immediate cart abandonment. Validate format structure via regex/checksum first, and accept the order if format passes.
2. Asynchronous validation retry queue
Put pending validation requests into an asynchronous background job with exponential backoff (e.g. 2m, 10m, 30m). Most national maintenance windows resolve within 1–2 hours.
3. Store timestamped audit evidence
Under Directive 2018/1910, you must prove due diligence. When VIES recovers, archive the official consultation number alongside the original transaction timestamp for complete audit protection.
Orientation only. Uptime indicators reflect real-time response checks against the European Commission's public VIES monitoring gateway. Network transit latency and local maintenance may cause temporary variations.

Why does VIES show some Member States as Unavailable?
The European Commission's VIES system is not a centralized database. It is a distributed gateway that forwards verification requests in real time to national tax servers across the 27 EU Member States and Northern Ireland. When a national tax database (such as Germany's BZSt or Italy's Agenzia delle Entrate) undergoes batch maintenance, updates, or experiences high volume, it returns an MS_UNAVAILABLE or TIMEOUT response.
How should an e-commerce or SaaS checkout handle MS_UNAVAILABLE errors?
Never block a customer checkout or mark their VAT number as invalid when a national database is offline. Best practice is to proceed with the transaction, log the timestamp and official error code as due diligence, and queue the validation for automatic retry with exponential backoff once the national server recovers.
What is the difference between the VOW Gateway and Member State availability?
VOW (VAT on the Web) is the central European Commission infrastructure that routes requests. Even when the central VOW gateway is fully operational, individual national tax databases can independently be down for nightly maintenance or weekend batch updates.
How often is this availability radar updated?
The radar queries the official European Commission check-status endpoint live with a 30-second cache window to provide up-to-the-minute reliability metrics without spamming authority endpoints.
The VAT Tools API provides automated offline queuing, cached historical evidence, and 99.9% uptime guarantees so your checkouts never drop.
