I'm not sure how things are now that number portability is available. A couple of my previous employers were cellular phone companies. It was my understanding that we had to purchase blocks of numbers within a prefix. Thus, for any given prefix (NXX) we had the entire range of 10,000 number (0000-9999). There may be numbers within the range that were reserved for special purposes. These were loaded as individual rows in a database that could be searched and assigned as needed. Thus, we knew what numbers we "owned" and also knew, from our subscriber records which numbers were in service. At that point, it would be a matter of database joins. However, I haven't worked in the industry for almost 8 years now (and my job was not very technical at the time), so I'm not sure what wrinkles things like number portability have thrown in or how it is handled.
