C39+ Barcode Generator

What is a Code 39+ Barcode?

Code 39+ (also known as Code 39 Extended) is an enhanced version of the traditional Code 39 barcode. While standard Code 39 supports only uppercase letters (A-Z), numbers (0-9), and a few special characters, Code 39+ extends this capability to include lowercase letters and additional symbols, making it more versatile for modern applications.

Key Features of Code 39+

✔ Supports Full ASCII Characters – Encodes uppercase, lowercase, and special symbols.
✔ Backward-Compatible – Scanners that read standard Code 39 can still decode the basic characters.
✔ No Mandatory Checksum – Like Code 39, it doesn’t require a checksum by default (but can include one for extra security).
✔ Widely Recognized – Used in industries needing extended character support.

How Does Code 39+ Work?

Code 39+ uses double-character encoding to represent lowercase and special ASCII characters. For example:

• The lowercase letter a is encoded as +A

• The symbol @ is encoded as +V

This method ensures compatibility with standard Code 39 scanners while expanding functionality.

Example of a Code 39+ Barcode:

If you encode the text Hello@123, the barcode will translate to:
* H +E L L +O +V 1 2 3 *

Applications of Code 39+ Barcodes

Code 39+ is useful in industries requiring extended character support, such as:

• Healthcare – Patient records with mixed-case names.

• Logistics & Shipping – Tracking codes with special characters.

• Retail & Manufacturing – Product labels with detailed descriptions.

• Asset Management – Serial numbers containing lowercase letters.
