APIFreaks Phone Validation API

What APIFreaks Phone Validation API is

APIFreaks Phone Validation API checks phone numbers against international numbering plans and returns validity information and number metadata in real time. It distinguishes numbers that are structurally possible from those that match a country's official numbering plan. Results can include a carrier where available, one of twelve line types, geographic location, possible time zones, and E.164, international, national, and RFC3966 formats. Carrier data may identify the original operator for recently ported numbers. Inputs can use an international number with a plus prefix or a local number paired with a two-letter region code. The endpoint is POST https://api.apifreaks.com/v1.0/phone/validation. Each successful request costs 2 credits; 4xx and 5xx responses do not incur a charge, and charged credits are refunded. New signups receive 10,000 free credits without a credit card. A free plan is available, with paid plans from $50 a month. The API does not establish whether a handset is on or a subscription is active. APIFreaks says it offers direct engineer support and a written 99.99% uptime SLA.

Who it suits

It suits developers adding signup checks, trust-and-safety engineers, and teams cleaning contact lists before SMS campaigns. It is useful when a workflow needs numbering-plan validity and number metadata, rather than confirmation of an active handset or subscription.

Limits

The Monthly Subscription plan is $50 a month for 600K API credits per month, with eight concurrent requests and a listed monthly lookup limit of 300000. Surcharges are 30,000 credits per $5, up to 300,000 credits; successful requests cost 2 credits. The one-off plan costs $100, paid once for 600K credits, with eight concurrent requests and no surcharge.

Getting started

1. Open the APIFreaks Phone Validation API website.
2. Sign up to receive 10,000 free credits; no credit card is required.
3. Send a POST request to https://api.apifreaks.com/v1.0/phone/validation.
4. Provide a number with a plus prefix, or a local-format number with its two-letter region code.
5. Choose a paid option if you need more credits: monthly subscription, yearly subscription, or one-off credits.

Verdict

The API provides numbering-plan checks and a range of metadata, with 10,000 credits for new signups. It does not verify whether a handset is on or a subscription is active, and carrier details may lag number porting.
