 string phoneNumberPattern = @"^\s*(?:\+?(\d{1,3}))?[-. (]*(\d{3})[-. )]*(\d{3})[-. ]*(\d{4})(?: *x(\d+))?\s*$";
 Regex phoneNumberRegex = new Regex(phoneNumberPattern);

Do you want to match (a subset of) phone numbers or numbers? (Your code indicates the former, your text the latter.) — Richard, Feb 19 '18 at 16:18

You can try the following :

^(\+)?\d{11}$

Explanation:

^          // should start with
(\+)?      // this makes sure + is at start only once
\d{11}    // followed by 11 digits
$         // end of line
