Phone Reputation screening is a great way to automatically prevent fake accounts and fraudulent behavior.
Please note, if you wish to verify phone numbers without passing an IP address, please use our dedicated phone number validation API. Test our phone validation service anytime with our free phone number validator tool.
Phone numbers are validated and analyzed for fraudulent activity by verifying the phone number exists with the carrier, without an SMS message or phone call. Forensic scoring and checks against our high risk user database, powered by Fraud Fusion™, are performed to determine if the phone number has been associated with confirmed reports of fraudulent behavior. Risk analysis for phone numbers will be returned in the "transaction_details" object.
Each phone number is validated to verify the correct syntax and country code. If a country code is not provided, our system can automatically detect the country code based on the IP address or similar user data. All phone numbers are validated against the local carriers in each country. This service supports phone validation for any country or region including cellular, VOIP, and land lines.
Verify users, payments, and applications with accurate phone number fraud prevention, combining advanced phone number risk scoring with deep phone reputation checks. Match names to phone numbers detect risky virtual numbers like VOIPs, disposable phone numbers, and similar high risk behavior signals. The IPQS phone number reputation API can also identify mobile and landline numbers that have been recently associated with bad actors and abuse.
Detect a wide range of suspicious phone numbers such as digital voice and VOIP lines. Accurately prevent robo callers and temporary or disposable phone numbers often used to bypass OTP (one time password) verification methods. IPQS supports worldwide coverage for high risk disposable numbers.
Retrieve the phone carrier and line type with each lookup request. Examples of the carrier include "AT&T", "Verizon", "Vodafone", "T-Mobile", etc. The telephone line type will be classified as Landline, Wireless, Toll Free, VOIP, Satellite, Premium Rate, Pager, Internet Service Provider or Unknown.
If the country dial-in code is known, then please supply it with the billing or shipping phone and include "+" symbol at the start of the number. This ensures our system can accurately verify the phone number. If the country code is unknown or the user's input is unvalidated, please pass the billing or shipping number without a "+" symbol. Our algorithms will attempt to detect the country code based on the IP address and billing/shipping country variables.
Additional user data such as physical addresses, email addresses, full names, devices, and IP addresses, can also be scored for risk analysis. Please view the Transaction Scoring documentation to learn more.
The example below incorporates scoring a phone number with an IP address. Phone numbers without a valid country code will assume the country code of the request's IP address. New to IPQS? View our base Proxy Detection API Documentation to get started..
