fglock++ beat me to the punch. However, please note that there are a few slight bugs with Lingua-EN-Numericalize. For instance, if you just feed in "Third Math St." it will return "3 Ma St.". Also, if any word ends in zero, four, fif, six, seven, eigh, or nin, it will put the corresponding number there. So "Thornin" becomes "thor9". This only happens at the end of the string. In the past, I've had to split /[\s-]/ the address and check each string to make certain it is numeric by checking str2nbr =~ /^\d+$/ then reevaluate the numerics together to come out with what it ought to be.

Just wondering, what cc processor do you use?
