What is a Code 39 Barcode?

Code 39, also known as Code 3 of 9, is a variable-length barcode that can encode uppercase letters, numbers, and several special characters. Developed in 1974, it was the first alphanumeric barcode symbology and is still widely used in industries like automotive manufacturing, defense, and healthcare due to its simplicity and ease of implementation.

Code 39 is a predecessor to more modern formats like Code 93 and Code 128, but remains widely used in industries that have established standards around it.
