Phone number validator: valid or fake, mobile or landline, and why

It checks the country code, the number of digits and the prefix against the national numbering plans of 245 countries and territories. If all three match, the number can exist.

Yes, in most countries: each prefix has a line type, like 06 and 07 for French mobiles. In the US and Canada, mobiles and landlines share ranges, so those numbers show as “Landline or mobile”.

No. An HLR lookup queries the mobile network live to see if the line is active. This tool checks the numbering plan: it tells whether a number can exist and what type it is.

Partly: it catches wrong lengths, unknown country codes and ranges no operator holds, like the UK's 07700 900xxx. A made-up number that falls in a real range still passes.

Not necessarily: it's the operator the number's range was originally allocated to. With number portability, the line may have moved to another one since.

No: the verdict is worked out in your browser. For the operator, area and time zone, a valid number goes through Enrow's server, which doesn't store it.

Yes, with no sign-up and no limit, one number at a time. For a whole list, use the Phone Number Formatter, also free.
