RegEx expression in phone number format (no more than 10 digits) that does not accept 0 or 1 as first number

I would like a reg ex expression that is in phone number format (XXX)XXX-XXXX ..that can be no more than 10 digits, and does not accept 0 or 1 as the first number.

Right now I have - 

/^(?!\(?[0-9]11\)?|\(?1[0-9][0-9]\)?|\(?0[0-9][0-9]?)(\(?\d{3}\)?\s?)(\(?\d{3})(\s?-?\s?)(\d{4})$/;

But it does not work.

Any help with this would be greatly appreciated.

You can use expression:

^\([2-9][0-9]{2}\)[0-9]{3}-[0-9]{4}$
  • ^ Assert position beginning of line.
  • \( An opening bracket (.
  • [2-9] First digit between 2 and 9.
  • [0-9]{2} Two digits.
  • \) A closing bracket ).
  • [0-9]{3} Three digits.
  • - A hyphen character.
  • [0-9]{4} Four digits.
  • $ Assert position end of line.

You can test it here.

We'll match 3 numbers not starting with 0 or 1 surrounded by parenthesis with \([2-9]\d{2}\) then 3 numbers alone with \d{3} then 4 numbers following a dash with -\d{4}.

Your full expression is /\([2-9]\d{2}\)\d{3}-\d{4}/

const regex = /\([2-9]\d{2}\)\d{3}-\d{4}/;
const valid = '(211)222-3333';
const invalid = '(111)222-3333';

console.log(regex.test(valid));
console.log(regex.test(invalid));
