Do the recycling code numbers that appear on the bottom of plastic containers apply only to the United States, or are they international?
The numbers are called the resin identification code, and they indicate what type of plastic the product is made of. (To learn what the numbers mean, download this chart from the American Chemistry Council.) This system is used all over the world, so no matter where you are, you’ll know whether your plastic is safe and if it’s recyclable.
