Why Code 39 for Internal Tracking?

Code 39 (or Code 3 of 9) is one of the oldest and most widely used barcode formats. It supports uppercase letters (A-Z), digits (0-9), and a handful of special characters. Its simplicity makes it compatible with almost any barcode scanner, making it great for closed-loop inventory or asset management systems.

Step 1: Prepare Your Asset ID List

Create a CSV or Excel (`.xlsx`) file with your asset IDs. Remember that Code 39 is typically uppercase. The first row must be a header, such as `AssetID`.
