RegEx Phone Number Validation

Question

I want to validate a phone number this format +905555555555.

How can I write a regex expression to test for this?

maybe not difficult for you, but if it wasn't for the OP he/she wouldn't post this question. — jackJoe, May 13 '11 at 08:13
@jackJoe but to learn something he should try it. maybe he can post some examples he tried before. — DanielB, May 13 '11 at 08:15

one "+" and 12 numbers. hint: escape the "+".

^\+(90)\([2-5]{1}\)[0-9]{9}

or not starts with +;

\+(90)\([2-5]{1}\)[0-9]{9}

thank you but The number after +90.. 5.. must be [2-5] like +90(2)642586989 or +90(3)642546987 +90(4)642546987 +90(5)642546987 you got it? – PsyGnosis May 13 '11 at 08:21
And starts with only +90 – PsyGnosis May 13 '11 at 08:25
this is What I want Thanks again /^\+(90)[2-5]{1}[0-9]{9}$/; – PsyGnosis May 13 '11 at 08:48
I hope this also guides you to write some basic regex :) – Mert Susur May 13 '11 at 09:10

if you need it to start with a "+" and a "9" and 11 digits:

^[+]9\d{11}$

I recommend that you understand how regEx work, take a look at this usefull tester: http://www.sweeting.org/mark/html/revalid.php

At the bottom they explain what each operator means.

Also there are all sort of examples at the internet.

EDIT: after reading the OP's comments, in order for the number to start with "+90" and then have 10 digits, you can use the following expression:

^[+]90\d{10}$

<script type="text/javascript">

var test = "+905555555555";
var re = new RegExp(/^\+[0-9]{12}$/gi);

if(re.test(test))
{
alert("Number is valid");
} else {
alert("Number is not valid");
}
</script>

To cover your additional specifications use this:

^\+90\([2-5]\)\d{9}$

You definitely need the anchors ^ and $ to ensure that there is nothing ahead or after your string. e.g. if you don't use the $ the number can be longer as your specified 12 numbers.

Adjusted a bit to answer question for a 12 digit regex.

// +905555555555 is +90 (555) 555-5555
let num = '+905555555555';
/^\+90\d{10}$/.test(num);

If it's exactly that format then you could use something like: /^\+\d{12}\z/

If you'd like to allow some spaces/dashes/periods in it but still keep it at 12 numbers: /^\+(?:\d[ .-]?){12}\z/ Then you could remove those other chars with: s/[ .-]+//g (Perl/etc notation)
