Hello, based on what you're describing, it could be possible the representative at the store was referring to the different rate center. The government has set-up "rate centers" or geographical areas for phone numbers. If the rate center for the previous address does not match the rate center for the new address, then the active AT&T telephone number cannot be ported over. We can look into this further and see what can be done to assist. If you're interested, please send this over to cox.help@cox.com, and we'll be delighted to assist further. -Kevin M.
