APIFreaks Phone Validation API is a REST service for developers and teams that need to verify phone numbers, enrich records, or normalize contact data. It checks possible and valid status against international numbering plans, then can return carrier information where available, line type, geographic location, time zones, and standardized formats. The product fits signup flows, CRM cleanup, contact-list maintenance, and SMS campaign preparation. Web and API access are available, with API-key authentication.

Its strongest fit is large-scale validation. The API supports numbers from 200+ countries, a separate bulk-validation endpoint, and four normalized outputs: E.164, International, National, and RFC3966. Line-type classification covers mobile, landline, VoIP, toll-free, and premium-rate numbers. The published category specification states a 300,000 monthly lookup limit, while the $50-per-month Monthly Subscription includes 600,000 API credits. Because the phone-validation endpoint uses 2 credits per successful request, that credit allowance corresponds to 300,000 successful single-number validations before any surcharge. Charges apply only to successful responses.

Pricing offers several ways to match usage. One-Off Credits cost $100 for 600K API credits, while the Yearly Subscription costs $500 per year for 600K API credits per month. The Monthly Subscription costs $50 per month for the same monthly credit allowance. A $20-per-month Lite plan provides shared organization billing and 10 free seats, but its API-credit allowance is not stated. The Enterprise plan adds custom scale and support with dedicated support. Choose APIFreaks when international coverage, bulk processing, normalized output, and metadata matter more than a simple single-number checker. Teams needing clear Lite-plan API quotas should compare the paid API plans before selecting it.
