Regular Expression - numeric only (Either a zero or 10 digit number)

Hello Experts,

I need a regular expression that will force the user to enter ether:

1) a zero
2) a ten digit number

So this needs to be numeric only, no spaces, dashes, ect.

Thanks!

I think you meant
^(0|\d{10})$

otherwise $ would not be required after 0 and ^ would not be required before \d{10}
