This page contains links to each state's department of alcohol beverage control. You can find information about direct shipping laws for beer (and wine), as well as permits for personal and commercial use.
Some states allow direct shipping or importation of beer and wine, some do not. Those that do sometimes require permits or place limits on the amount of beer you can ship. Those links are included as well.
If you cannot find the info you are looking for, then you can email or call a member of the state's ABC. In my experience, they are very responsive and helpful!
You can ship beer or wine TO YOURSELF without a permit
Again, if you cannot find the info you are looking for, then please contact your state or the state you are looking to ship beer to. It is best to be on the safe side when shipping your beer!
Have fun sharing the beers you love!
