Title: Incorrect syntax.

The [\(]{1} simplifies to \( here. The [\)]{1} simplifies to \) here. The [ ]{1} simplifies to \s here. The [\-]{1} simplifies to - here. When there is only one character there is no need to use 'character group' syntax. In any case, stating {1} is aways redundant too.

It allows for some invalid phone number where the area code and local code start with 0. ex: (011) 012-1234 ^([\(]{1}[2-9]{1}[0-9]{2}[\)]{1}[ ]{1}[2-9]{1}[0-9]{2}[\-]{1}[0-9]{4})$ <----http://www.area-codes.com/area-code-faq.asp----> “NPA” stands for Number Plan Area, commonly called Area Code. “NXX” refers to the three digits of a phone number immediately following the area code, also called the “exchange” or the “Central Switching Office Designation. In the number (555) 222-3333, the NPA is “555” and the NXX is “222”. The “N” numbers, or the first number of the NPA and of the NXX, can be any number from 2-9; 0 and 1 are reserved for special purposes. All the remaining numbers, or “X” numbers, can be any number from 0-9. The last four digits of a phone number are called the “Subscriber Line Identifier,” or “SLID”, and can be any number from 0-9..

the extra brackets and quantifiers are completelly unnecessary... @"^\(\d{3}\) \d{3}-\d{4}$" is just as good only more 'readable' :-)
