You will only be able to purchase "Florida Resident" passes with some kind of Florida id. You cannot buy "Florida Resident" passes for anyone but yourself. You must prove that you live or own property in Florida. If not, then you must buy a regular-price pass. I cannot buy a "Florida Resident" ticket for my son who lives in GA. AAA use to have a deal that would allow grandparents to buy tickets for their grandchildren, but they discontinued that a while ago.
This chart helps - scroll down to look at Florida Resident prices:
