Where is an SKU number found?

Answer 1

When you go shopping, and pick up a box or can of something, do you see the bar code on it? It's usually on the bottom side of the container.

On that bar code - usually on the bottom - is the SKU number (Short for Stock-keeping Unit). It tells the computer system what the product is, the model or size, various other information the company uses, and the price. The number itself is the human language version of the bar code.

The clerk runs it over the computer scanner to ring the item up.
