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 50.00 USD per 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 is for
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.
What is good
- New signups receive 10,000 credits without a card.
- Returns validity and multiple phone-number formats.
- Can provide carrier, line type, location, and time zones.
- 4xx and 5xx requests do not incur credit charges.
What to know first
- Does not confirm handset availability or active subscriptions.
- Carrier data may show an original operator after porting.
- Successful requests cost 2 credits each.
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.
