Overview

Veriphone is a phone number validation API that also returns carrier and line-type details for numbers worldwide. It lets you check if a phone number is real and active, which helps reduce fraud in sign-up forms. Even the free tier supports a meaningful number of lookups per month.

Beginner Tip

Start with the free plan—it includes 1,000 verifications per month, which is plenty for testing. Include the country code as a separate parameter if you are not certain the number has one embedded.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Request 
const url = "https://api.veriphone.io/v2/verify?phone=+14155552671&key=YOUR_API_KEY";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"

});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
