Phone validation regex
RegexPhone NumberRegex Problem Overview
I'm using this pattern to check the validation of a phone number
^[0-9\-\+]{9,15}$
It's works for 0771234567
and +0771234567
,
but I want it to works for 077-1234567
and +077-1234567
and +077-1-23-45-67 and +077-123-45-6-7
What should I change in the pattern?

Solution 1 - Regex
Please refer to this SO Post
/\(?([0-9]{3})\)?([ .-]?)([0-9]{3})\2([0-9]{4})/
- (123) 456 7899
- (123).456.7899
- (123)-456-7899
- 123-456-7899
- 123 456 7899
- 1234567899
are supported
Solution 2 - Regex
This solution actually validates the numbers and the format. For example: 123-456-7890 is a valid format but is NOT a valid US number and this answer bears that out where others here do not.
If you do not want the extension capability remove the following including the parenthesis: (?:\s*(?:#|x.?|ext.?|extension)\s*(\d+)\s*)? :)
edit (addendum) I needed this in a client side only application so I converted it. Here it is for the javascript folks:
var myPhoneRegex = /(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})\s*(?:\s*(?:#|x\.?|ext\.?|extension)\s*(\d+)\s*)?$/i;
if (myPhoneRegex.test(phoneVar)) {
// Successful match
} else {
// Match attempt failed
}
hth. end edit
This allows extensions or not and works with .NET
(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})(?:\s*(?:#|x\.?|ext\.?|extension)\s*(\d+))?$
To validate with or without trailing spaces. Perhaps when using .NET validators and trimming server side use this slightly different regex:
(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})\s*(?:\s*(?:#|x\.?|ext\.?|extension)\s*(\d+)\s*)?$
All valid:

800 555 1212

Invalid #s
234-911-5678
314-159-2653
123-234-5678
> EDIT: Based on Felipe's comment I have updated this for international.
Based on what I could find out from here and here regarding valid global numbers
This is tested as a first line of defense of course. An overarching element of the international number is that it is no longer than 15 characters. I did not write a replace for all the non digits and sum the result. It should be done for completeness. Also, you may notice that I have not combined the North America regex with this one. The reason is that this international regex will match North American numbers, however, it will also accept known invalid #
such as +1 234-911-5678
. For more accurate results you should separate them as well.
Pauses and other dialing instruments are not mentioned and therefore invalid per E.164
\(?\+[0-9]{1,3}\)? ?-?[0-9]{1,3} ?-?[0-9]{3,5} ?-?[0-9]{4}( ?-?[0-9]{3})?
With 1-10 letter word for extension and 1-6 digit extension:
\(?\+[0-9]{1,3}\)? ?-?[0-9]{1,3} ?-?[0-9]{3,5} ?-?[0-9]{4}( ?-?[0-9]{3})? ?(\w{1,10}\s?\d{1,6})?

Solution 3 - Regex
Consider:
^\+?[0-9]{3}-?[0-9]{6,12}$
This only allows +
at the beginning; it requires 3 digits, followed by an optional dash, followed by 6-12 more digits.
Note that the original regex allows 'phone numbers' such as 70+12---12+92
, which is a bit more liberal than you probably had in mind.
The question was amended to add:
> +077-1-23-45-67 and +077-123-45-6-7
You now probably need to be using a regex system that supports alternatives:
^\+?[0-9]{3}-?([0-9]{7}|[0-9]-[0-9]{2}-[0-9]{2}-[0-9]{2}|[0-9]{3}-[0-9]{2}-[0-9]-[0-9])$
The first alternative is seven digits; the second is 1-23-45-67; the third is 123-45-6-7. These all share the optional plus +
followed by 3 digits and an optional dash -
prefix.
The comment below mentions another pattern:
> +077-12-34-567
It is not at all clear what the general pattern should be - maybe one or more digits separated by dashes; digits at front and back?
^\+?[0-9]{3}-?[0-9](-[0-9]+)+$
This will allow the '+077-' prefix, followed by any sequence of digits alternating with dashes, with at least one digit between each dash and no dash at the end.
Solution 4 - Regex
I have a more generic regex to allow the user to enter only numbers, +
, -
, whitespace
and ()
. It respects the parenthesis balance and there is always a number after a symbol.
^([+]?[\s0-9]+)?(\d{3}|[(]?[0-9]+[)])?([-]?[\s]?[0-9])+$
false, ""
false, "+48 504 203 260@@"
false, "+48.504.203.260"
false, "+55(123) 456-78-90-"
false, "+55(123) - 456-78-90"
false, "504.203.260"
false, " "

Solution 5 - Regex
/^[0-9\+]{1,}[0-9\-]{3,15}$/
so first is a digit or a +, then some digits or -
Solution 6 - Regex
First test the length of the string to see if it is between 9 and 15.
Then use this regex to validate:
^\+?\d+(-\d+)*$
This is yet another variation of the normal* (special normal*)*
pattern, with normal
being \d
and special
being -
.
Solution 7 - Regex
I tried :
^(1[ \-\+]{0,3}|\+1[ -\+]{0,3}|\+1|\+)?((\(\+?1-[2-9][0-9]{1,2}\))|(\(\+?[2-8][0-9][0-9]\))|(\(\+?[1-9][0-9]\))|(\(\+?[17]\))|(\([2-9][2-9]\))|([ \-\.]{0,3}[0-9]{2,4}))?([ \-\.][0-9])?([ \-\.]{0,3}[0-9]{2,4}){2,3}$
I took care of special country codes like 1-97... as well. Here are the numbers I tested against (from Puneet Lamba and MCattle):

Here is the regex for Ethiopian Phone Number. For my fellow Ethiopian developers ;)
phoneExp = /^(^\+251|^251|^0)?9\d{8}$/;
It matches the following (restrict any unwanted character in start and end position)
- +251912345678
- 251912345678
- 0912345678
- 912345678

The following regex matches a '+' followed by n digits
var mobileNumber = "+18005551212";
var regex = new RegExp("^\\+[0-9]*$");
var OK = regex.test(mobileNumber);
if (OK) {
console.log("is a phone number");

console.log("is NOT a phone number");

^+?\d{3}-?\d{2}-?\d{2}-?\d{3}$
You may try this....
How about this one....Hope this helps...
^(\\+?)\d{3,3}-?\d{2,2}-?\d{2,2}-?\d{3,3}$
Solution 13 - Regex
^[0-9\-\+]{9,15}$
would match 0+0+0+0+0+0, or 000000000, etc.
(\-?[0-9]){7}
would match a specific number of digits with optional hyphens in any position among them.
What is this +077 format supposed to be?
It's not a valid format. No country codes begin with 0.
The digits after the + should usually be a country code, 1 to 3 digits long.
Allowing for "+" then country code CC, then optional hyphen, then "0" plus two digits, then hyphens and digits for next seven digits, try:
^\+CC\-?0[1-9][0-9](\-?[0-9]){7}$
Oh, and {3,3} is redundant, simplifes to {3}.
Solution 14 - Regex
This regex matches any number with the common format 1-(999)-999-9999 and anything in between. Also, the regex will allow braces or no braces and separations with period, space or dash. "^([01][- .])?(\(\d{3}\)|\d{3})[- .]?\d{3}[- .]\d{4}$"

JS code:
function checkIfValidPhoneNumber(input){
"use strict";
if(/^((\+?\d{1,3})?[\(\- ]?\d{3,5}[\)\- ]?)?(\d[.\- ]?\d)+$/.test(input)&&input.replace(/\D/g,"").length<=15){
return true;
} else {
return false;
}
}
It may be primitive in terms of checking phone number, but it checks that input text is compliant with E.164 recommendation.
- Maximum phone length is 15 digits
- Country code consists of 1 to 3 digits, could be preceded with plus (could be omitted)
- Region (network) code consists of 3 to 5 digits (could be omitted but only if country code is omitted)
It allows some delimiters in phone number and around region code (.- ) For example:
> +7(918)000-12-34 > > 911 > > 1-23456-789.10.11.12
all are compliant with E.164 and validated
