Multiple ways are there. For example:

var regex = /^\d{3}-\d{3}-\d{4}$/;
console.log(regex.test('999-999-9999'));
console.log(regex.test('9999-999-99999'));

//OR
var regex2 = /^[0-9]{3}-[0-9]{3}-[0-9]{4}$/
console.log(regex2.test('999-999-9999'));
console.log(regex2.test('9999-999-99999'));

You can also write specific to a country or area. See this example.

If you are taking it from user input validate it like this:

var val = document.getElementbyId('yourInputId').value;
if(regex2.test(val)){
  alert("Success!!");
}
else{
  alert("Failure!!");
}
