CODE-39 Barcode Format
CODE-39 was developed in 1974 by U.S. firm Intermec and was the first alphanumeric coding created. A total of 43 symbols can be used on CODE-39 barcodes, including all roman alphabet characters, numbers 0-9 and certain symbols.
CODE-39 symbols are larger than CODE-128 symbols, and cannot be used on small items. They can be read by the majority of barcode scanning systems. Readable symbols such as letters and numbers are not required on these symbols, CODE-39 bar codes can consist of bar code only.
Unlike the similar CODE-128, CODE-39 does not include a check digit. CODE-39 is selfchecking.
Standard CODE-39 features that are supported by the Barcode Software include:
- Optional mod 43 check digit;
- Optional full ASCII charset support;
- Adjustable bar widths for printing error compensation;
- Optional start/stop characters and star marks in text;
- Manual and automatic bar height modes;
- Font customization; and
- Customizable front and back colors with spot color support for EPS file export.
High-quality PNG and TIFF CODE-39 barcode images can be exported to your desktop, or dragged-and-dropped into Adobe Photoshop and Illustrator, using the Barcode Generator.
