How is SKU different from Barcodes (UPC, ISBN, etc.)?

Mainly, barcodes are series of unique characters that is issued by a standard organization. Also, these barcodes are used globally.

For Example:

  • UPC (Universal Product Code) is a 12-digit code that serves as retail product identity. Do you notice that barcode scan by cashiers/clerk in a grocery store? That is an example of UPC.
  • ISBN (International Standard Book Number) is a numeric commercial book identifier. If you see those codes at the back of a book, that is the ISBN.

Thus, SKU is different from a barcode.
