It's usually displayed on a sticker over the coin and dollar bill mechanisms. If no information is available, go to step two. If it's a Coke or Pepsi machine, look for the machine information on the side. A serial number and an outlet number (for a Coke machine) or an asset number should be present (for a Pepsi machine). Check the bottom of each cup for a recycling code. Some machines take coins, some will only take bills. Some will take both, while others are restricted to one type of currency. If you find that the machine is disabled but still contains money, call the phone number listed on the sticker. Most companies will send an employee to collect the machine. If you cannot find this number, check with your local bottler. They may have more information on what to do with abandoned soda machines. Finally, if all else fails, put up a sign and pay a small fee to have someone remove it.
