I'm a software programmer and I'm new to Nextel. In a software program I am writing, I ask the operator to enter a Nextel ID. I'm expecting an entry like 123-12-1234. I guess these are the Area ID, Network ID and Member ID components. Are those the correct terminology names?

What is the numeric range of each component? I'm looking to the minimum possible value and the maximum possible value for each component. Is it 1 through 9999 or what?
Area ID
Network ID
Member ID
