What is the SKU number used for?

I never understood what is the SKU used for. I always put a random number. Anyone knows its real use?

That's your own code number for the product. short for Stock Keeping Unit: http://en.wikipedia.org/wiki/Stock-keeping_unit

Apple uses SKU numbers to distinguish multiple versions of the same app.

As TSB said you can put any random numbers.

I have a company and use project number. it's just for my own records.
If you don't have a company you can ad a random number.
