Validating international phone numbers

However, to match the full phone number as well, we can use the expression 1?

', and the rest of the digits '\d' and '\d' respectively. ' to catch the space or dashes between each component.

This should be combined with good regex [email protected] Q I disagree. After reading through these answers, it looks like there wasn't a straightforward regular expression that can parse through a bunch of text and pull out phone numbers in any format (including international with and without the plus sign).

The original problem is trying to handle phone number validation because it was trying to handle all the possible formatting options. Here's a regex for a 7 or 10 digit number, with extensions allowed, delimiters are spaces, dashes, or periods: ^(? Here's what I used for a client project recently, where we had to convert all phone numbers in any format to tel: links.

I answered this question on another SO question before deciding to also include my answer as an answer on this thread, because no one was addressing how to require/not require items, just handing out regexs: Regex working wrong, matching unexpected things From my post on that site, I've created a quick guide to assist anyone with making their own regex for their own desired phone number format, which I will caveat (like I did on the other site) that if you are too restrictive, you may not get the desired results, and there is no "one size fits all" solution to accepting all possible phone numbers in the world - only what you decide to accept as your format of choice. Note that it doesn't have any special rules for how many digits, or what numbers are valid in those digits, it just verifies that only digits, parenthesis, dashes, plus, space, pound, asterisk, period, comma, or the letters are present.
