UPC is the standard bar code for items for sale to the public. It is the code seen on items at the local supermarket. UPC-A is a fixed-length, numeric only bar code.
It contains:
1 digit for a system number
5 digits for the manufacturer number
5 digits for the product number
One checksum digit
The position and value of the digits is standardized by a grocery industry committee. UPC-A and UPC-E also allow two- or five-digit supplemental numbers.
UPC-A and UPC-E codes have an automatic checksum.
UPC-E is ideal for small packages, because it is the smallest bar code available. This symbology contains the same information as UPC-A, except that at least four zeros are suppressed.
Only tags with the system character of 0 can be encoded with this symbology.
UPC-A and UPC-E codes have an automatic checksum.
