They are allocated - to the phone company that owns the NXX. The only way you can find out if that phone company is willing to rent them to you is to ask them.<br>
<br>
What you are asking for is like a centralized directory of which apartments are occupied. There is no such thing. You have to decide which building (NXX) you're interested in and then see who the property manager (LEC) is. Then find out from the property manager
either by asking them or seeing if they publish their own list somewhere. It's unlikely they would have a public list because it would not only be used by prospective tenants but also by door-to-door salespeople and competitive landlords.<br>
<br>
A block of 50 DIDs is pretty tiny. For such a small amount, I would probably begin my search by just calling a few random numbers from the 50 and see where the call ends up.<br>

<br>
Right, but that report doesn't have granularity below the NXX level, so I can't find out if the 50 DIDs after my block of 00 to 49 are allocated to anyone else. :(<br>
