Free Code 39 Barcode Font Download

Code 39 Barcode Generated with the Free Code 39 Font

This free barcode font can be used to generate medium-size Code 39 barcodes in TrueType or OpenType format, which can encode uppercase letters, numbers and some special symbols. This is a fully-functional freeware font, not a demo or evaluation.

This Code 39 barcode font may be used by individuals and organizations that have a gross annual revenue of less than $500,000 USD or are classified as nonprofit for tax purposes, excluding government and military organizations. For details, please review the free product section of the License Agreement.

The free barcode font may also be used with an accompanying hardware product provided by IDAutomation and educational organizations such as schools and universities. Any other use requires the purchase of the Code 39 Font Advantage Package.

Download the Free Barcode Font

If a scanning device is needed to read barcodes for testing or other purposes, consider these barcode scanners.

Windows Installation

To install the TrueType barcode font in Windows, run the INSTALL.EXE program in the downloaded .zip file or perform the following for manual installation:

Mac OSX Installation

To install the TrueType font in Mac OSX, run the MPKG file in the downloaded .zip file or perform the following for manual installation. Mac support for classic OS (7.1 - 9x) requires the Code 39 Font Advantage Package.

Using the Code 39 Barcode Font

This free barcode font is supplied in the M (medium) size. If other heights or the Mac Classic, PCL, LaserJet soft font or PostScript formats are needed, consider purchasing the Code 39 Font Advantage Package, which supplies the font in 6 different heights (XS, S, M, L, XL, XXL).

To generate a Code 39 barcode from a font, the data-to-encode is to be surrounded by asterisks as the start and stop characters, i.e. *153969*. In Microsoft Word, the start and stop characters should be "!" instead of the asterisk because of a formatting issue, i.e. !153969!. To hide the asterisks from appearing in the human-readable below the barcode, use the parenthesis surrounding the data, i.e. (12345).

If the font is not in font selection list of the application after installation, check the application settings. Most applications allow the ability to disable a feature that lists the font names in the fonts list. For example, if the font is not in the Microsoft Office fonts list, follow these steps:

  1. Select Customize from the Tools menu.
  2. In the Options tab, unselect the "list font names in their font" check box.
  3. Click close.

IDAutomation provides Microsoft Access, Excel and Word examples in the Windows version, and additional examples for OpenOffice Calc, iWork Numbers and Pages for the Mac version of the package. After installation, there will be icons for these examples in the Start - Programs - IDAutomation.com Code 39 Font program group on Windows and Applications - IDAutomation Free Code 39 Font for Mac on OSX. There are also several application integration guides available to assist.

If a higher-density barcode than Code 39 is required, consider Code 128 or a 2D barcode such as PDF417 or DataMatrix for something that can withstand damage and still scan correctly. For an evaluation of barcode sizes and types, refer to that section in the Barcoding for Beginners Tutorial.

To learn more about the Code 39 barcode, refer to the Code 39 FAQ and Tutorial.

Reading Code 39 Barcodes

Code 39 is one of the most common barcodes in use today, and thus virtually every barcode scanner will be capable of reading Code 39. IDAutomation provides several Code 39 barcode readers for many different systems, including Windows, Mac and Linux.

Barcode scanners act as an external keyboard, so that anything scanned with the scanner is output wherever the cursor is blinking on the computer screen as though it had been typed on the keyboard. This process is called keyboard emulation. Learn how to scan data into applications with a barcode scanner.

Free Code 39 Font Distribution within Applications

This free Code 39 font may not be distributed within an application, or as part of an application's installation files. This type of bundling requires a Developers License for the Code 39 Font Advantage package.

Developers may create a distributed application that accesses the IDAutomationHC39M font name and request that users download this free font only if they meet the free license qualifications. If a user does not meet the free license qualifications, they must be instructed to purchase the Code 39 Font Advantage Package, which includes the IDAutomationHC39M font. Developers may also utilize the IDAutomation affiliate program to receive 20% commission on fonts that are purchased from IDAutomation for their programs.

Code 39 True Type Font Specifications

The free Code 39 font X dimension (width of the narrow bar) for various point sizes is listed below. The narrow-to-wide ratio is 3:1 which is recommended by international standards.

Point Size Approximate X Dimension (1 mil = .001")
48 .102 cm 40 mil
36 .076 cm 30 mil
32 .069 cm 27 mil
30 .064 cm 25 mil
28 .058 cm 23 mil
24 .051 cm 20 mil
20 .043 cm 17 mil
18 .038 cm 15 mil
16 .033 cm 13 mil
12 .025 cm 10 mil
8 .018 cm 7 mil
6 .013 cm 5 mil
* To print at a different X dimension, find the point size that has the X dimension closest to what is needed and use this formula to find the point size needed:
12 * (X dimension needed) / (X dimension at 12 points) = (point size)

When using a printer with less than 600 DPI, the following point sizes should be used to create accurate barcodes:

203 DPI Printer (thermal printer) 300 DPI Printer
6, 12, 18, 24, 30, 36... 4, 8, 12, 16, 20, 24, 28, 32, 36...

IDAutomationHC39M is the only free size provided. In the Code 39 Font Advantage package, however, 24 different versions of the fonts are provided to support human-readable versions in addition to different height-width requirements. The last character in the font name determines the height of the barcode with the shortest being "XS" and the tallest being "XXL".
