This is now going off on two different things, one radio related and one not. yea each store has an internal corporate ID #. Now, the curve radios have the ability to be programmed to communicate with each other using a 4 digit code as a profile ID # they call it. The default stated in the curve manual is 0000. Each radio must be on the same profile ID to communicate. The old RDM2070d's were similar in that specific DPL codes could be changed by the user. The walmart default code would show on the screen as code 057 which the manual charts to DPL 131. I'd imagine their walmart ordered curve radios would be similar, all walmart ordered models would have the same profile ID unless changed locally by the store. and rest of the discusssion, they also have the same internal wifi store network login, a zebra handheld could go from store to store, and there was an additional box for the store ID number, in addition to the users credentials
