The phone number will all be in the format of the example number, but they won't all be that same number.

:point_right: In your regex, "5" only represents 5. To represent any digit, use the code "\d".

You're so close! The format is for them to be in is "555-555-5555". So this could be any combination of numbers, but in this format. For example, you could be looking for "123-456-7890" or "098-765-4321". Your regular expression is only looking for the values "555-555-5555". To fix this, you need to check for any combination of numbers. (Try using the \d regEx)! Good luck!
