UPC-E is a compressed six-digit form of UPC-A that suppresses zeros to fit on small packages.
How it works
It algorithmically removes runs of zeros from a UPC-A number and reconstructs the full code at scan time.
Where it's used
Small North American retail products such as travel-size goods and single-serve items.
