UPC-A and UPC-E look similar but serve different purposes. If you are choosing a barcode for your packaging, here is what sets them apart.
UPC-A: the standard choice
UPC-A is the familiar 12-digit barcode you see on almost every retail product. It is widely scannable, universally accepted, and the default for nearly all listings.
Unless your packaging is unusually small, UPC-A is the right format.
UPC-E: built for small packages
UPC-E compresses a UPC-A by removing zeros, producing a shorter barcode that fits on tiny items like cosmetics, gum, or small electronics accessories.
It encodes the same underlying product number, just in a space-saving form. Scanners expand it back to the full 12 digits automatically.
Which should you use?
Choose UPC-A by default. Only consider UPC-E when physical space is genuinely too tight for a standard barcode.
Whichever you use, the product identification number behind it is what matters for your listings.
Frequently Asked Questions
Is UPC-E just a shorter UPC-A?
Essentially yes — it is a zero-suppressed version of a UPC-A that encodes the same product number in less space.
Do all scanners read UPC-E?
Modern retail scanners read UPC-E and expand it to the full number automatically.
Which is better for online selling?
For online listings the format barely matters — what counts is a valid GTIN. UPC-A is the simplest default.
