I want to find a number that starts with "221" and is an 11 digit number.

For example: 221XXXXXXXX

Does Google support any method to find something like this? Perhaps with regex or wildcards?

This is not a duplicate of the regex question, as having an incidental answer to an unasked question elsewhere is not the same as a direct answer to a direct question. – Myrddin Emrys Feb 21 '12 at 2:10
This is not duplicate question. – I'll-Be-Back Feb 21 '12 at 10:21
I've tried to modify the question to make it clear it's not a duplicate. – Al E. Dec 11 '12 at 3:00
The "regex" question referred to above is webapps.stackexchange.com/questions/19673/… – Al E. Dec 14 '12 at 14:14

This used to be possible. As far as I can tell, this capability has been removed. I suspect that they were uncomfortable with how easy it was to find lists of credit card numbers, phone numbers, and social security numbers using this function.
