Question:

Apple is asking for a SKU number when I'm filling out the information in iTunes Connect, what is that?

Answer:

■ The unique UTF-8 alphanumeric identifier for the app. Keep the following points in mind:

■ The SKU is any alphanumeric sequence of letters and numbers you’d like to use to be uniquely identified in our system. You are free to create any string of UTF-8 letters and numbers, as long as it is unique to your developer account.

■ Your SKU Number is not editable after submitting your metadata.
