Question

What does the last five digits of barcode indicate

Answer 1

Answer:

UPC-A barcodes carry GTIN-12 numbers as defined by GS1 US.

In its standard version (UPC-A), the bar code consists of a five digit manufacturer number and a five digit product number.

In addition there is a 1 digit number system identifier at the start of the code. The 100% code is the same size as a 100% EAN.
