I need a reg ex which accepts 10 to 11 digits phone number, hyphen , parenthesis (in right order) and spaces are allowed (I will remove all of the afterwards).
So all following string should be accepted by it.

12223334444

2223334444

1(222)333-4444

1(222) 333-4444

1 (222) 333-4444

1 (222) 333 - 4444

(222)333-4444

(222) 333-4444

(222) 333 - 4444

1-222-333-4444

1 - 222 - 333 - 4444

222-333-4444

222 - 333 - 4444

I have made this , but it accepts many other strings

^(.*?[.-|( |]|[0-9][^d]*(d+)[^d].* [.-|)].*)$

I am using C#.

Try this:

^(?:1[s-]*)?(?:(d{3})|d{3})[s-]*d{3}[s-]*d{4}$

See it here

Breakdown:

• 
  ^ start of string


• 
  1[s-]* _(optional) Matches a literal 1 and zero or more whitespace characters and/or dashes


• 
  (?:(d{3})|d{3}) matches one of the following:
  
  
  
  
  • 3 digits d{3} surrounded by opening ( and closing ) parenthesis
  
  
  • 3 digits d{3} not surrounded by parenthesis
  
  
  
  


• 
  [s-]* zero or more whitespace characters and/or dashes


• 
  d{3} another 3 digits


• 
  [s-]* zero or more whitespace characters and/or dashes


• 
  d{4} another 4 digits


•
