Neutrino Phone Validate vs Veriphone

Neutrino Phone Validate is an API for parsing and checking local and international phone numbers, with location information in its responses. It accepts international numbers in E.164 format; local numbers require a country code or an IP address. Depending on the number, results can include validity, line type, local and international formats, location, country, currency code, and prefix network. Line type is inferred from the prefix and is unavailable in some countries, including most of the NANP region; Neutrino says HLR Lookup can provide carrier-level detection. The product page lists average round-trip latency of 15 ms for requests within the same data center or region, a maximum inbound rate of 500 requests per second, and concurrency of 250. A free account has limited daily requests, around 10–25 depending on the API, with no expiry. Paid Phone Validate tiers are £8 per month for 10,000 requests per 24 hours, £38 per month for 100,000, and £190 per month for one million. Paid API plans can include any or all Neutrino APIs, with separate daily quotas.

Veriphone validates phone numbers through an API or a web CSV workflow, returning validity, carrier, line type, and country information. The service says it supports 243 countries and territories and can format numbers as E.164, international, or local. Validation checks whether a number follows its country’s official numbering plan; it does not confirm that the phone is currently switched on. The instant API uses a GET request and returns JSON, while CSV uploads can be downloaded with results for each row. Current Carrier Lookup consults national portability registries and can return original carrier, current carrier, and ported status; a resolved lookup costs 10 credits. Standard validation costs 1 credit. The Free plan is free and includes 1,000 credits each month. One-time packages range from $24, paid once for 10,000 credits to $999, paid once for 5,000,000 credits; purchased credits do not expire. Veriphone also offers Zapier and Make integrations. API numbers are processed in memory, while infrastructure request URLs are retained for 30 days and CSV uploads remain until deleted or may be removed after 90 days.
