How it works
Three steps from sign-up to your first validated field.
- 1
Get your API key
Sign up for free — no credit card required. Your API key is ready in seconds.
- 2
Send a request
POST a VAT number, IBAN, national ID, email or phone number to our REST endpoint. Works with any language or framework.
- 3
Get instant results
Get JSON back with the verdict and the normalized value. For VAT: what VIES answered, and whether it came live or from cache. For email: MX, typo and disposable checks and a 0–100 quality score.
Every call shows up in your dashboard
VAT audit trail
Proof of every VAT check, ready when the tax office asks
Put your own VAT number on file and every EU VAT lookup is kept with the consultation number VIES issues — the reference that proves which number you checked, when, and what VIES answered. Search it in your dashboard, export it as CSV.
How long we keep it
- Free
- 30 days
- Starter

Each record keeps the window of the plan you were on when the check was made, so downgrading never shortens evidence you already collected. Retention rules vary by member state; nothing here is tax advice.

Frequently Asked Questions
Everything you need to know about VerifNow.
VerifNow is a real-time API that validates the fields billing and onboarding forms depend on: EU VAT numbers (checked against VIES, answered from cache when a registry is down), IBANs, national IDs, emails and phone numbers — one API key, one quota, one bill.
We run multi-layer checks: syntax verification, DNS and MX record lookups, typo detection (e.g. gmail.con → gmail.com), disposable and role-based address detection, domain reputation signals, and a quality score from 0 to 100. The depth of checks depends on your plan.
No. VerifNow is a REST API — just send an HTTPS request with your API key and get a JSON response in milliseconds. Official SDKs are available for Java and Spring Boot (io.verifnow:verifnow-spring-boot-starter on Maven Central) and for Node.js and TypeScript (@verifnow/sdk on npm), plus ready-to-paste cURL examples.
Yes. The Free plan gives you 250 validations per month running the full STANDARD check set — DNS and MX lookups, typo detection, disposable and role-based detection, and a 0–100 quality score. Same checks as the Starter plan, no credit card, no time limit.
Your API keeps working — there is no service interruption. Extra requests beyond your plan's quota are billed per unit at the end of the billing period. The higher your plan, the lower the overage price.
Typical response time is under 50 ms (p50), measured on our production endpoints. VerifNow runs with monitoring, alerting and zero-downtime deployments. We do not publish a contractual uptime guarantee at this stage — get in touch if you need an SLA.
Absolutely. All traffic is encrypted over HTTPS, API keys are stored securely with rotation support, and validation inputs are never persisted beyond the processing window. We collect the minimum data necessary to operate the service.
Yes. The client dashboard lets you track requests, errors, and latency in real time. You can filter by endpoint, monitor trends after deployments, and manage your API keys — all from one place.
Start for free — no credit card required
Wire it once: one integration for VAT, IBAN, IDs, email and phone, and a checkout that keeps working when a registry goes down.
