Overview

PhoneValidationAPI is a phone-number validation service delivered through an HTTP API and web interface. It is best suited to developers who need number metadata and disposable-number screening in signup, routing, or data-cleaning workflows without contacting the number. Its breadth is useful, but its results do not confirm that someone controls or answers a number.

Key features

It accepts E.164 numbers or national-format numbers paired with a country parameter, parsing them with Google's libphonenumber. A single API call can return format, country, region, line type, carrier, and disposable or burner-number signals. Line classifications include mobile, fixed line, VoIP, toll-free, premium-rate, and shared-cost, among other categories. Putting these checks together can simplify screening, though the value depends on how much your workflow needs carrier and line-type data.

Disposable-number detection checks carrier information and known prefix ranges against a maintained list of VoIP and burner numbers. Responses also carry a confidence label—verified, likely, uncertain, low, or invalid—giving an application a way to distinguish stronger from weaker signals. Confidence varies by country, and some numbering plans make line types ambiguous; there is no universal accuracy percentage to rely on. Treat the label as one input to a decision, not a guarantee.

The service validates metadata without sending an SMS or placing a PSTN call. That avoids contacting the number, but means it does not establish current reachability or user control. Integration uses HTTP requests with Bearer-token authentication, and the provider says no SDK is required. OpenAPI 3.0 documentation and a Postman collection offer practical starting points for developers.

The privacy policy says communications use HTTPS/TLS, passwords are hashed with Argon2id, and API keys are hashed at rest with SHA-256. Submitted numbers are stored in validation logs as SHA-256 hashes; plain numbers are not retained beyond the immediate request except when batch processing requires it. The operator says it is based in France and complies with the EU GDPR and French Data Protection Act. Support typically replies within 24 hours on business days.

Pricing

The Free plan costs $0 per month and includes 100 API requests per month, real-time validation, country and line-type detection, carrier identification, disposable/VoIP filtering, HTTPS, and Bearer authentication. It is a useful allowance for small prototypes, but 100 requests a month is a tight ceiling for production signup flows.

Basic costs 14.99 USD per month, billed $14.99 /month, for 6,000 API requests per month and standard email support. It fits modest recurring workloads, but has no batch endpoint in its listed features. Professional costs 59.99 USD per month, billed $59.99 /month, and raises the quota to 60,000 requests per month while adding an asynchronous batch endpoint for up to 10,000 numbers per batch. That is the more suitable tier for scheduled bulk work.

Enterprise costs 129.99 USD per month, billed $129.99 /month, and includes 300,000 requests per month, priority email support (24h), and a custom rate limit on request. It suits higher-volume services that need the larger quota or priority support. Custom plan pricing is bespoke for more than 300,000 lookups per month, with dedicated support or volume discount. There is no published paid-plan annual term or trial to factor into these prices.

Platforms

PhoneValidationAPI is available through an API and on the web. The HTTP interface can be used with any HTTP client, so teams are not tied to a particular SDK.

Who it's for

Choose it if your application needs phone-number parsing, carrier and line-type metadata, and disposable-number signals together, especially when you want to screen numbers without sending a message or call. It is less suitable when a decision requires proof of reachability or ownership, or when country-level ambiguity makes a confidence label too weak for the consequences of a mistake.

Pros and cons

Pros: One call returns multiple useful metadata and screening signals, reducing the need to combine separate checks.
Pros: No SMS or call is sent, which suits workflows that need validation without contacting users.
Pros: The Professional plan supports asynchronous batches up to 10,000 numbers, a meaningful option for bulk processing.
Cons: Confidence varies by country and some line types are ambiguous, so results should not be treated as definitive.
Cons: Validation does not prove that a number is reachable or controlled by the person submitting it.
Cons: The free allowance is 100 requests per month, and the Basic plan's 6,000-request cap may constrain growing workloads.

Alternatives

libphonenumber-js is a free, open-source JavaScript/TypeScript library under MIT and Apache-2.0 licenses; choose it when you want a library rather than a hosted validation service. For another phone API, IPQualityScore Phone Validation API has a free plan and trial, with monthly volume tiered flat-rate pricing, no monthly contracts, and 1,000 free lookups per month. numlookupapi.com offers a Basic plan at $9.99 /mo with 5,000 requests and batch validation, so it may suit a lower-cost, lower-quota starting point. Veriphone includes 1,000 validations per month on its free plan, with carrier and line-type data plus bulk CSV and API access, making it worth considering when a larger free allowance matters. Abstract Email Validation API is an email-validation alternative rather than a phone-number service. Accessibility Test Framework for Android is another alternative in the directory. Neutrino Phone Validate provides a phone validation API with a free account limited to around 10–25 requests per day. Numverify is a freemium phone validation API built and maintained by APILayer. See the phone number validation software directory for more options.

Verdict

PhoneValidationAPI is a strong fit for developers who want parsing, carrier and line-type data, and disposable-number screening in one HTTP integration, with a clear path from a small free allowance to batch and higher-volume plans. Choose it for metadata-driven screening, not as proof of reachability or ownership; look elsewhere if your workflow needs that assurance or cannot tolerate country-dependent ambiguity.
