Question 1

How do I check if a phone number is valid?

Accepted Answer

Enter it in the validator above, ideally with its + country code. It checks the number against the country's numbering plan and returns whether it's valid, its country, its line type and a formatted version.

Question 2

Can it tell if a number is a mobile or a landline?

Accepted Answer

Yes, in most countries the number's prefix shows whether it's mobile, landline, VoIP or toll-free. In the US and Canada many prefixes can be either, so the result may say landline or mobile.

Question 3

Can it detect VoIP numbers?

Accepted Answer

Yes, where the numbering plan identifies VoIP ranges. Through the API, live carrier data (where available) also detects VoIP on numbers that have been ported.

Question 4

Does it call or text the number?

Accepted Answer

No. Nothing is sent to the number; it's a lookup only.

Question 5

Is the phone validator free?

Accepted Answer

Yes, 5 checks a day without signing up. Create an account for the API, list cleaning and more checks.
