Phone Number Verifier – Real-Time Active Number Check

IPQualityScore’s IPQS phone number validator verification solution uses global carrier intelligence to verify the validity of phone numbers during registrations, checkouts, and lead form submissions. It also performs a real-time phone provider lookup to determine if the number is active and connected to their service. This is important because a number that is active can help you identify fraudulent users and chargebacks.

Carrier Details & Line Types globally (Landline, Cellular, VOIP, Prepaid) – IPQS connects directly to telecom backbones from major carriers worldwide to quickly and accurately detect if a phone number is active or disconnected. This allows you to enrich data with risk information including if the number is registered in the Do Not Call Registry and whether or not they have a prepaid plan or a credit card account.
