.NET EAN-8 Generator - Barcode EAN-8 Introduction

EAN-8, also known as European Article Number 8, UPC-8, GTIN-8, GS1-8, EAN/UCC-8, is a linear barcode and is derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large.

  • Under demo package, copy barcode folder and its contents to your IIS, and create a new virtual directory.
  • Restart IIS, navigate to http://YourDomain:Port/barcode/linear.aspx?DATA=1234567&TYPE=12.
  • To create barcode EAN-8 image in html or aspx pages, you can insert a image tag (img) into your page.
