1D linear Digits only 11-12 digits No No*

Retail barcode used heavily in North America. Give it 11 digits and the check digit is computed; give it 12 and the check digit is validated.

Example

036000291452 
UpcA::create('03600029145')->render();

Usage

use Atelier\Barcode\UpcA;

echo UpcA::create('03600029145')
    ->scale(2)
    ->height(80)
    ->render();

Options

Method Default Description
scale(int) 2 pixels per module
height(int) 80 bar height in pixels
margin(int) 9 quiet zone, in modules
foreground(string) #000000 bar color
background(string) #ffffff background color
withText(bool) true show the human-readable value

modules() returns the raw bar pattern. value() returns the full 12-digit code.

foreground() and background() take any CSS colour. Scanners read contrast, not hue, so a dark-on-light pair works and the reverse does not.

Limits

  • Exactly 11 or 12 digits, nothing else: throws InvalidCodeException otherwise.
  • If 12 digits are given, the 12th must be the correct check digit.

UPC-A has no phone-number semantics; it is digits-only product identification.
