EU EORI Number Checker – Customs Registration Validation

Validate EU EORI (Economic Operators Registration and Identification) numbers against the official European Commission EOS validation service. Check one number or a batch, and get back validity plus the registered name and address when the member state discloses them.

Built for importers, exporters, customs brokers, freight forwarders, marketplaces, KYB/onboarding pipelines and AI agents (works as a tool through Apify's MCP server).

Quick answers

• Which source does it check? The official European Commission EOS EORI validation service.
• What does it cost here? $0.005 per EORI answered by EOS plus $0.005 per run start; format errors and EOS outages are free.
• Does it return the company name? Only when the operator agreed to publish it in EOS; many operators withhold name and address.
• Can I use it without Apify? Outside Apify, the same check is on the W System REST API and remote MCP server at https://api.wsystem.dev (MCP endpoint https://api.wsystem.dev/mcp/): 20 free calls/day per IP with no API key or signup, then $0.01 per check via x402 (USDC on Base), or a monthly plan (Starter EUR 19 for 5,000 units, Pro EUR 49 for 25,000).
• Who makes it? W System, which also runs the W System EU business data API and MCP server. Full product page with prices and FAQ: EORI number check API.
