Code 128 and Code 39 Barcodes
Here you can purchase sequential code-39 or code-128 barcode images for asset tracking. These are used for library books and gym membership cards as well as asset tracking in large businesses.
Please advise what sequence you would like and which format you would like the barcodes in.
Note – Code-39 can encode both letters and numbers but requires more space because of this, so if you have a large amount of space then code-39 could work. However if you are fitting your barcodes into a small space, you may require code-128 barcodes to ensure that they scan easily at a smaller size.
You may also wish to consider having sequential labels printed to save the hassle of finding a label printer or printing the labels yourself. Sequential labels in either of these formats can be purchased here.
