Advanced Phone Number Risk Scoring for Fraud Prevention

Streamline verification of users and payments with powerful phone number reputation, totaling to over 30 phone number risk signals that prevent fraud and abusive behavior. IPQS enhances your team's awareness of bots, fake accounts, and suspicious payment with both positive and negative signals for comprehensive phone number fraud risk scoring.

Improve identity verification and fraud prevention with real-time phone number intelligence. IPQS calculates an overall Fraud Score which can be used to quickly block or flag suspicious accounts and high risk payments. While many phone numbers look legitimate to the naked eye, these are some of the factors that IPQS machine learning algorithms use to detect fraudulent phone numbers:

  • Phone Number Blacklists — Access the Internet's most comprehensive phone number blacklist to improve fraud prevention for risky users, bad actors, and high risk payments.
  • Carrier Lookup — Lookup phone number data including carrier, line type (landline, cell phone, VOIP), location, fraud risk score, and much more. Check any number.
  • Number Activity — The velocity and frequency of phone number can provide greater feedback to identify legitimate behavior, such as account registrations, purchases, etc. These signals help indicate that a real user is actually using the number, rather than a fraudster that is cycling through 30+ different phone numbers for malicious purposes.
  • Phone Number Identity Verification — Append data such as first and last names, location, email address, and similar identity data points that can help verify the user is legitimately associated with a phone number. Reverse identity checks and live appends can quickly verify a phone number matches a user.
  • VOIP & Disposable/Temporary Numbers & SMS ServicesPhone number reputation is a powerful signal for quality, especially when a fraudster is using a disposable phone number or any type of abusive VOIP. Known fraudulent virtual numbers can quickly elevate a score to 90 or higher.
  • Reverse Phone Lookups - Combine phone number identity resolution with world class phone number risk scoring services. Advanced risk analysis paired with phone validation identifies fake, disconnected, and temporary phone numbers.

What is Phone Number Fraud Risk Scoring?

Phone number fraud & risk scoring is the process of detecting fraudulent behavior by analyzing the phone number reputation associated with a user or payment. High risk numbers, such as phone numbers associated with multiple or fake accounts, fraudulent payments, and suspicious behavior are likely to represent bad actors with malicious intent. Virtual numbers such as VOIP can also elevate risk as they can be used to mask a user's true identity.

What is Phone Number Intelligence?

Phone number intelligence enriches phone numbers with additional data to analyze the risk score and quality of a user or payment. View important phone number attributes such as identity (name, email, address), location, number line type, risk score, carrier & provider details, and similar analytics.
