IPQualityScore Phone Validation API review
A broad fraud-screening API with useful enrichment, but a high entry price and lookup limits.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
IPQualityScore Phone Validation API verifies phone numbers through real-time API lookups and bulk CSV validation. It returns validation, activity, carrier, line-type, location, identity, risk, and reputation signals, including checks for disconnected, invalid, disposable, and temporary-SMS numbers. The product is aimed at teams screening users, leads, applications, payments, or transactions, with positioning for small and medium-sized businesses, enterprises, and fraud-prevention organizations.
Pricing is structured as monthly plans. Free costs $0 per month and includes phone validation, API access, CSV uploads, and 1,000 lookups per month. Startup costs $99 per month and adds bulk CSV validation, while SMB Basic costs $499 per month and adds transaction scoring and extra scoring settings. SMB+ costs $999 per month and adds address verification, reverse identity checks, and a 99.5% SLA guarantee. Enterprise adds custom monthly lookups, bulk CSV reports, Mobile SDK access, a 99.9% SLA guarantee, and Enterprise support. Each plan requires a minimum monthly commitment, and the listed monthly lookup limit is 5,000.
Its ecosystem is a strong fit for teams that need phone checks inside existing business, communications, payment, or security workflows. Integrations include WordPress, Shopify, Salesforce, HubSpot, Klaviyo, Twilio, Stripe, Splunk, Rapid7, and Palo Alto Cortex XSOAR. The feature breadth suits fraud and risk screening better than a narrow phone-format checker, particularly when carrier, line type, reachability, reputation, and enrichment signals matter together. Choose it when those signals and bulk validation justify the paid tiers; smaller teams with light lookup needs may prefer the Free plan, while buyers seeking a simpler validation-only tool may not need its wider screening scope.
