1. UPC-E Barcode Introduction
UPC-E is also known as Universal
Product Code version E, UPC-E Supplement 5/Five-digit Add-On, UPC-E Supplement
2/Two-digit Add-On, UPC-E+5, UPC-E+2, UPC-E0, E0, UPC-E1, E1, GTIN-12 with lead
"0", GS1-12, UCC-12
UPC-E is a variation of UPC-A
which allows for a more compact barcode by eliminating "extra" zeros.
Since the resulting UPC-E barcode is about half the size as an UPC-A barcode,
UPC-E is generally used on products with very small packaging where a full
UPC-A barcode couldn't reasonably fit.
A UPC-E barcode represents 6 digits with an implied number system 0.

Sample of a UPC-E Barcode with Data property = " 123450".
The data displayed by UPC-E barcode image has the following structure:
-
1 digit for Number System (0), set by library automatically.
-
6 digits for UPCE data set through Data property
-
1 digit for checksum, calculated automatically by barcode library.
Add-On or Supplement code
The Add-On Symbols were designed to encode information
supplementary to that in the main bar code symbol on periodicals and paperback
books. The Add-On can be composed of 2 or 5 digits only.

Sample of an UPC-E Two-Digit Add-On Barcode

Sample of an UPC-E Five-Digit Add-On Barcode
2. UPC-E Encoding Data Scope
UPCE Barcode for Java supports
- 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
3. How to Generate UPC-E Barcode in Java Class?
The following Java code illustrates how to create a UPC-E barcode, and output to various formats
1 Linear linear = new Linear();
2 linear.setType(Linear.UPCE);
3 linear.setData("123450");
4 linear.renderBarcode("c:/barcode.gif");
5 BufferedImage bufferedImage = linear.renderBarcode();
6 byte[] barcodeBytes = linear.renderBarcodeToBytes();
7 Graphics2D g = ...
8 Rectangle2D rectangle = ...
9 linear.renderBarcode(g, rectangle);
10 OutputStream outputStream = ...
11 linear.renderBarcode(outputStream);
- Create a Linear barcode object (line 1)
- Set Linear object barcode type to UPC-E (line 2)
- Set UPC-E barcode data to encode (line 3)
- Encode generated UPC-E barcode into gif image file (line 4)
- Generate UPC-E and output to BufferedImage object (line 5)
- Generate UPC-E in bitmap and output to byte[] (line 6)
- Generate UPC-E and draw to defined area (Rectangle2D) on Graphics2D (line 7-9)
- Generate UPC-E and output to OutputStream (line 10-11)
4. How to Generate UPC-E Barcode Image in Java Web Applications?
There are two methods to create UPC-E barcode images in your Java web applications.
-
The simplest way is to stream barcode image using our buildin barcode servlet application.
- Download the Barcode for Java Trial Package, and unzip it.
- Under java_barcode_trial package, copy barcode folder to your java servlet container like tomcat.
- Restart tomcat. Now you have installed successfully.
- To test your installation, open your web browser and navigate to
http://YourDomain:Port/barcode/linear?Data=123450&Type=UPCE
- To create barcode image in your JSP or html page, you need pass the url to IMG tag src value.
For example,
<img src="http://YourDomain:Port/barcode/linear?Data=123450&Type=UPCE" />
Using this method, it will not generate any barcode images in your server side.
-
The second method is to generate barcode images in your server side

6. Java UPC-E Barcode Property Settings
-
Set the type property to Linear.UPCE, or Linear.UPCE_2, or Linear.UPCE_5
Servlet URL Parameter: "Type". Value: 43 (UPCE), 44 (UPCE +2), 45 (UPCE +5). Sample: &Type=43
-
Set the data property with the value to encode.
Type is String.
- Valid Data Scope:
- 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
- Valid Data Format:
6 digits. DO NOT include the first digit (the UPCE number system) and the last digit (the checksum character).
- Sample: "123456"
Servlet URL Parameter: Data.
-
Set the sData property with the supplement value to encode. Type is String.
User should only provide 2 digits for UPCE_2, and provide only 5 digits for UPCE_5.
Servlet URL Parameter: SData.
-
addCheckSum property is not applied here. Barcode Library will always add a check character in the last digit (modulo 10). The UPC-E check digit has the same value of the check digit on the equivalent UPC-A number.
-
Set upceNumber property. UPCE number system.
Default is 0. Valid values are: 0 or 1.
Servlet URL Parameter: UPCENumber. Sample: &UPCENumber=0
-
Barcode image size settings:
-
Set property uom (Unit of Measure) for properties X, Y, leftMargin, rightMargin, topMargin and bottomMargin.
Default is Linear.UOM_PIXEL (0). Valid values are Linear.UOM_PIXEL (0), Linear.UOM_CM (1), Linear.UOM_Inch (2).
Servlet URL Parameter: "UOM". Value: 0 (pixel), 1 (cm), 2 (inch). Sample: &UOM=0
-
Set the X (for barcode module width) and Y (for barcode module height) properties.
Both types are float. Default X is 3. Y is 75.
Servlet URL Parameter: "X", "Y". Sample: &X=3&Y=75
-
Set the leftMargin, rightMargin, topMargin and bottomMargin properties, and types are all float.
Default values are 0 for all 4 margin settings.
Servlet URL Parameter: "LeftMargin", "RightMargin", "TopMargin", "BottomMargin". Sample: &LeftMargin=0
-
Set the resolution property (Value is expressed in DPI - Dots per inch).
Default is 72 dpi.
Servlet URL Parameter: "Resolution". Sample: &Resolution=72
-
Setting up text style in barcode image:
-
Set the showText properties. If this value is true, barcode data will be displayed with the barcode.
Default is true.
Servlet URL Parameter: "ShowText". Value: "t" (true), "f" (false). Sample: &ShowText=t
-
Set the textFont property. The font used to display text in barcode image.
Default is new Font("Arial", Font.PLAIN, 11).
Servlet URL Parameter: "TextFont".
Value format: [font name]|[font style]|[font size].
Sample Values: &TextFont=Arial|Bold|12
-
With rotate property, you can display barcode horizontally or vertically.
Value can be
- 0 (Linear.ANGLE_0),
- 1 (Linear.ANGLE_90),
- 2 (Linear.ANGLE_180),
- 3 (Linear.ANGLE_270)
Default value is 0.
Servlet URL Parameter: "Rotate". Sample: &Rotate=0
