UPC-E is a compacted form of the UPC-A barcode symbology that usually carries a GTIN-12 that has been zero compressed.

Also known as: UPC-E0.

UPC-E+2 is an extension of UPC-E that includes a two-digit add-on.
UPC-E+5 is an extension of UPC-E that includes a five-digit add-on.
UPC-A is the full size form of UPC-E.
UPC-E Composite is a variant of UPC-E that should be used when a CC-A or CC-B GS1 Composite 2D component is required.
UPC-E1 is a UPC-E with a number system of 1. This is not defined by any symbology standard.

Standards: ISO/IEC 15420, BS EN 797, GS1 General Specifications.

The data field takes either seven or eight digits, optionally followed by a space then two or five digits if an EAN-2 or EAN-5 add-on is required.
Alternatively, the data field may contain eleven or twelve digits of a UPC-A to produce the equivalent UPC-E symbol, provided that the input can be zero suppressed.
If seven digits of primary data are supplied then the check digit is calculated automatically. Otherwise the provided check digit will be verified.
For a regular UPC-E the primary data should start with "0". For a UPC-E1 the data should start with "1".
The includetext option should normally be supplied.
