Thanks for you help, I have a web form and get spammers putting 12345 as their # all the time! How would I incorporate this into a standard php contact form? Thanks for you time and the script!

This is incorrect.

The 4 digit (1 after area code) can never start with a 0 or a 1. It can be 2-9 only.

Valid: 5552221234
Invalid: 5551231234

Thus the correct regexp is:
[2-9]{1}[0-9]{2}[2-9]{1}[0-9]{2}[0-9]{4}

I tried this code in my order form on the site and it works perfectly, just what I needed.

Actually, I don’t think the exchange (middle 3) can start with a 1 or 0 either
