Yep.  The address on their FCC license, anyway, if it's a street  
address and not aPO box.

There is a method to assigning street address numbers in the US, and  
geocoders will make a reasonable effort (some better than others) to  
derive a lat/lon from an address.

Xastir uses data derived from the census TIGER data, and it does  
quite a reasonable job based on the few addresses I've been able to  
verify; YMMV.
