What is SmartPhoneValidator?

SmartPhoneValidator is a phone number validation API and web app. It tells you whether a phone number is valid, what kind of line it is, which carrier it belongs to, where it was issued and how risky it looks, for US, Canadian and international numbers.

What a check returns

  • ValidityWhether the number is real and correctly formed for its country, shown as Valid, Risky or Invalid.
  • Line typeMobile, landline, VoIP, toll-free or premium.
  • CarrierThe network the number belongs to, where the data is available.
  • Location and timezoneThe country, region or city the number was issued in, and its timezone.
  • E.164 formatThe international +countrycode format that SMS providers and databases expect.
  • Risk scoreA 0–100 score with the reasons behind it, such as VoIP, disposable or made-up looking numbers.

What it does not do

  • A valid result does not prove who owns the number, and it does not guarantee that a text message will arrive. Use a one-time code if you need to confirm ownership.
