Answer 4

You can check out Parsify Format here - https://www.mashape.com/parsify/format#endpoint-Phone-Number

It will return your number in several formats e.g.

{ "e164": "+1234567890", "national": "234567890", "international": "+1 234567890", "valid": false, "type": "UNKNOWN" }

You can get a more extensive response if it's a real number

Answer 5

At http://www.geonames.org/ they have a database you can download, theres regEx rules for phone numbers included in the country info dataset.

http://download.geonames.org/export/dump/

Look for the 'countryInfo.txt' file.

I suggest you build your own validator based upon that.

Answer 6

Like it was said in the answers to the other question, no one's seen any for Java, and like you said, it would be nearly impossible due to the difference of phone number formats across the world.

And if you know the different formats for the regions that you're targeting, then it's usually pretty easy to implement it in regular expressions.
