Spec score 7.9 #8 of 25 in Phone Number Validation Software

What it is

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.
