UPC-E
| Kind | Charset | Capacity | URL | Phone |
|---|---|---|---|---|
| 1D linear | Digits only | 6-8 digits | No | No* |
Zero-compressed UPC for small packaging. It accepts the 6-digit payload, 7 digits with number system, or the full 8 digits with check digit. It can also compress a compatible UPC-A value.
Example
UpcE::create('042100')->render();

use Atelier\Barcode\UpcE;
echo UpcE::fromUpcA('004000002101')

modules() returns the raw bar pattern. value() returns the UPC-E value, and
expandedValue() returns the equivalent UPC-A value.
The UPC-A that this symbol expands to, from expandedValue(). Same product, same check digit, and about two thirds wider: that difference is the whole point of UPC-E.
Limits
- Number system must be
0or1. - Full 8-digit input must carry the correct check digit.
fromUpcA()throws when the UPC-A value is not compressible to UPC-E.
UPC-E has no phone-number semantics; it is digits-only product identification.
