Please improve telephone number recognition

International phone numbers starting with the + symbol seem not recognized. Note that all the possible international prefixes are known (a list can be found at http://en.wikipedia.org/wiki/List_of_country_calling_codes ) so the regexp could be very strict. Something like:
\+(code1|code2|...)[ \-\(\)0-9]{3,}
(or possible requiring an even longer sequence of digits to protect from recognizing numbers with a leading explicit positive sign).

Right now the regex recognizes only numbers roughtly in US format (XXX) XXX-XXXX .

Oops, sorry, it looks like the regexp should already handle international number. However, we format them as:
+1 202-371-2121
and it looks like they are not recognized.

Also, please note that for international numbers starting with a +, the tel: url should include the + character; eg:

+1 212 555 1212 -> tel:+12125551212 and NOT tel:12125551212 as a phone call software would not be able to understand wether to add the international calling prefix (001 for the US, 00 for most of Europe) when placing the call.

Hey, thanks for the info. Great to know. Will update for this.

English numbers, e.g. 020 1111 1111 are not being recognised also.

Here's an example:

(Regex from https://github.com/gregjacobs/Autolinker.js/blob/master/src/matchParser/MatchParser.js#L114 )

Seems like it doesn't stop on newlines either. (fixed at #129)

@Gdelprete @mfc-julius @gregjacobs would this work better:

http://rubular.com/r/KzyezB1d0I

/((\+|00)[1-9]{1}[0-9\040]{7,14})|((?:(\+)?\d{1,3}[-\040.])?\(?\d{3}\)?[-\040.]?\d{3}[-\040.]\d{4})/

It basically has its own part for European numbers (first) and second part for the rest.

Thoughts?

[gregjacobs]

Nicely done. Let me give this a try and I'll let you know!

[simison]

FYI; I wanted to do more checking on length of the European numbers (that {7,14} bit) — but didn't yet find time to dig more.

[simison]

FYI, this looks interesting: https://github.com/chriso/validator.js/blob/master/validator.js#L83-L100

[simison]

Woah. So Google's phone number i18n recognition is massive

[garychapman]

@gregjacobs Would it be possible to make the various regex patterns externally configurable? We'd love it if Autolinker could recognise various Australian phone numbers, for example. Thanks!
