PhoneValidationAPI review
A focused validation API with disposable detection, diagnostics, and a free plan.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PhoneValidationAPI is a hosted REST service for developers who need to validate phone numbers without sending SMS or placing calls. It accepts E.164 and national-format input, then returns validity, country and region data, line type, carrier information where available, disposable-number detection, confidence labels, and per-check diagnostics. The API is suited to signup-form cleaning, contact-data hygiene, routing decisions, and fraud-signal reduction. It runs through web and API access, with Bearer-token authentication over HTTPS.
Pricing follows a freemium structure with monthly billing. The Free plan includes real-time validation, country and line-type detection, carrier identification, disposable and VoIP filtering, and HTTPS and Bearer authentication. Basic costs $14.99 per month and adds standard email support. Professional costs $59.99 per month and adds an asynchronous batch endpoint for up to 10,000 numbers per batch. Enterprise costs $129.99 per month and adds priority email support with a 24-hour response target plus a custom rate limit on request. Custom offers bespoke pricing for high-volume usage, with dedicated support or volume discounts. Basic, Professional, and Enterprise include a 14-day money-back guarantee when less than 10% of quota is used.
Its strongest distinction is diagnostic depth within a narrow API-focused workflow. Developers can combine format handling, regional and line-type classification, carrier data, disposable-number detection, and confidence labels in one validation response. Asynchronous batches make the Professional tier more suitable for larger contact-cleaning jobs than a synchronous-only service. The trade-off is that validation remains data- and signal-focused: HLR lookups are unavailable for now, and carrier identification depends on available data. Choose PhoneValidationAPI when your application needs REST validation and richer phone-number diagnostics; consider an alternative if SMS or call-based verification is required.
