Java Barcode EAN-13 Generator Introduction
Top
Java Barcode is a
Java barcode generator library which generates high quality 1D (linear) and 2D (matrix) barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects.
Barcode EAN-13 Introduction
EAN-13 barcode (originally European Article Number) is a barcoding standard which is a superset of the original 12-digit Universal Product Code (UPC) system developed in the United States. The EAN-13 barcode is defined by the standards organisation GS1. The numbers encoded in EAN-13 bar codes are product identification numbers which are called Japanese Article Number (JAN) in Japan. All the numbers encoded in UPC and EAN barcodes are known as Global Trade Item Numbers (GTIN), and they can be encoded in other GS1 barcodes.
EAN 13 Valid Data Scope
Java EAN 13 Generator encodes:
- 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
How to generate EAN-13 barcodes in Java class?
Top- Create a new object of
com.onbarcode.barcode.EAN13 - Set the encoding EAN-13 data using method
setData() - Print EAN-13 barcode in a PNG image file through method
drawBarcode()
EAN13 barcode = new EAN13(); barcode.setData("123456789012"); barcode.drawBarcode("c://Output//OnBarcode.com//java-ean13-demo.png");
EAN-13 Add-on Code
EAN-13 may include 2-digit or 5-digit add-on code. Call method
setSupData() to include add-on code in EAN-13 barcode using Java Barcode Generator library.
EAN13 barcode = new EAN13(); barcode.setData("123456789012"); barcode.setSupData("12"); barcode.drawBarcode("c://Output//OnBarcode.com//java-ean13-addon-2-digits.png");
EAN13 barcode = new EAN13(); barcode.setData("123456789012"); barcode.setSupData("12345"); barcode.drawBarcode("c://Output//OnBarcode.com//java-ean13-addon-5-digits.png");
EAN-13 Valid Encoding Character Set in Java
Top
EAN-13 barcode encodes digits (0-9) only.
The valid EAN-13 data size is 13 digits. It includes the first 12-digit data text and the last check digit.
Using OnBarcode Java Barcode Generator library, you can input the first 12 data digits or the complete 13 digits.

setTextFont()
EAN13 barcode = new EAN13(); barcode.setData("123456789012"); barcode.setTextFont(new Font("ocr-b", Font.BOLD, 42)); barcode.drawBarcode("c://Output//OnBarcode.com//java-ean13-text-font-adjusted.png");
Create and customize EAN-13 barcode in C# ASP.NET, MVC, WinForms apps
Top
Using OnBarcode Java Barcode Generator library, you
can apply the following barcode options to further customize the EAN-13 barcode labels in Java class, JSP page, Servlet, BIRT reports, Jasper reports applications.
Here we will show how to customize the EAN-13 barcode image below using the above EAN-13 barcode options in C# class.
- ShowQuietZoneIndicator: Display or hide EAN barcode quiet zone indicator. The default value is
true. - UPCEANLeadDigitSpace: The space between the first digit and the start character bar. The default value is
0. - UPCEANTrailDigitSpace: The space between the stop character bar and the quiet zone indicator. The default value is
0.
Here we will show how to customize the EAN-13 barcode image below using the above EAN-13 barcode options in C# class.
EAN barcode quiet zone indicator
You can choose to show or hide the EAN-13 barcode quiet zone indicator in EAN-13 barcode label. By default, the Java barocde generation library will print
the EAN-13 barcode quiet zone indicator mark on the end of the EAN-13 barcode.
The property
The property
ShowQuietZoneIndicator will allow you to show or hide the EAN-13 quiet zone indicator.
barcode.ShowQuietZoneIndicator = false;
EAN-13 the first and last digit space
Using Java Barcode library, you can increase the space between the EAN-13 first code and the start bar, and the space between the stop char and quiet zone indicator through
barcode options
UPCEANLeadDigitSpace and UPCEANTrailDigitSpace in your Java class, Servlet, Jasper or BIRT report projects.
barcode.UPCEANLeadDigitSpace = 10; barcode.UPCEANTrailDigitSpace = 10;
How to Create & Print Barcode EAN-13 Java web application?
TopEAN-13 in JSP pages
- Under demo package, copy barcode folder and its contents to your tomcat.
- Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=012345678912&TYPE=EAN13
- To create bar code images in html or jsp pages, you can insert a image tag (img) into your page.
- For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=012345678912&TYPE=EAN13"/>
EAN-13 in Java Servlet
OnBarcode Java Barcode Generator library supports EAN-13 barcode generation in both Jakarta Servlet and Javax Servlet.
import com.onbarcode.barcode.AbstractBarcode;
import com.onbarcode.barcode.EAN13;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
public class BarcodeServlet extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException
{
try {
EAN13 barcode = new EAN13();
barcode.setData("012345678912");
ServletOutputStream servletoutputstream = response.getOutputStream();
response.setContentType("image/jpeg");
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
// Generate EAN13 barcode & output to ServletOutputStream
barcode.drawBarcode(servletoutputstream);
} catch (Exception e) {
throw new ServletException(e);
}
}
}

Common Asked Questions
What is the EAN-13 code?
EAN-13 is a 13-digit barcode, which includes 12 GS1 data digits and 1 check digit. EAN is short for European Article Number,
and now it is renamed as GTIN (Global Trade Item Number). EAN 13 code will be used to uniquely identify retail products worldwide.
In Java class, you can input EAN-13 12 digits data text or whole 13 digits with check sum, the Java barcode generator library will generate and print the EAN13 barcodes through class

What is the difference between EAN and EAN-13?
EAN barcode includes EAN-13, EAN-8. You can use OnBarcode Java barcode library to encode and print EAN-13, and EAN-8 barcode images easily in Java projects
What is the EAN-13 barcode layout?
The whole 13 digits EAN-13 code is grouped as follows:
You will find more information here: EAN-13 barcode data structure.
- 2 or 3 digits for the number system or the country code
- 5 or 4 digits for the manufacturer code or prefix
- 5 digits for the product code
- 1 digit for the check digit
You will find more information here: EAN-13 barcode data structure.
How to check if the EAN-13 barcode created in Java is valid?
The last digit of EAN-13 is a check digit. It will be used to verify the first 12-digit GS1 data message.
Using Java barcode library,
the generated EAN-13 barcode check digit is calculated and verified by the barcode SDK API.
What is the minimum size for EAN-13?
The GS1 recommended minimum size for an EAN-13 barcode is 30mm in width and 20 mm in height.
You can customize the EAN-13 barcode image with and height through method
setBarcodeWidth and setBarcodeHeight in
Java class com.onbarcode.barcode.EAN13
How do I print high quality EAN-13 barcodes in Java?
To print good quality EAN-13 barcodes in Java projects, you need follow the rules below.
- The EAN-13 barcode image resolution (DPI) is the same or higher than the printer's resolution.
In Java class
com.onbarcode.barcode.EAN13, customize the barcode image resolution through methodsetResolution() - The EAN-13 barcode human readable text is using the legible fonts. The GS1 System recommends use OCR-B font to draw EAN-13 text label.
Here is the sample Java source code to apply fonts:
setTextFont(new Font("OCR-B", Font.PLAIN, 13))
