Is BE0403170701 valid?

Yes: BE0403170701 returned valid:true from VIES at the time of this check and resolved to SA ELECTRABEL.

What does BTW stand for?

BTW is short for BTW-identificatienummer (Belasting over de toegevoegde waarde). It is the local name for Belgium's VAT identification number.

vatverify queries VIES directly for every validation. Valid responses are cached for 30 days; invalid responses are cached for 24 hours. The "Re-check now" button bypasses the cache and forces a fresh registry call.

Can I integrate this in my own code?

Yes. POST /v1/validate with {"vat_number":"BE0403170701"} and an Authorization Bearer header. Free plan: 500 validations per month, no credit card.
