    Please click the [ Mark Complete ] button at the bottom of this page when you’ve achieved these goals: 

  • Understand the use of asset-tracking barcode images (Code 128 and Code 39), and the process of ordering from International Barcodes.
  • Be able to explain the difference between Code 128 and Code 39 asset tracking barcodes and how they should be respectively used.
  • Understand why Code 128 and Code 39 should not be used for products that are for sale in retail stores.
  • Explain why we recommend that you label very small items using a Code 128 barcode.
  • Explain why it is safest to use only numeric digits on Code 128 and Code 39 barcodes.

 

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.

We can supply code 128 or code 39 barcodes in your preferred format – either jpeg, pdf, eps, tiff or bmp.

Please advise what format you want (e.g. jpeg), what size barcodes you want (e.g. 3cm wide x 2cm high), what sequence you would like (e.g. 1000 barcodes, starting at 39123000 and ending at 39123999) and which type of code you want (e.g. Code 128).

Once we receive your order, we will manually create the barcodes for you, and email them to you. This will normally take 12-24 hours (between Monday-Friday) depending on the time of day/week that you make the order. Our normal office hours are 9am-5pm Mon-Fri (NZ time).

 

The Difference between Code 128 and Code 39:

Code 128 barcode:

Code 39 barcode, with a higher data density:

 

TIP: We recommend that you label very small items using a Code 128 barcode.
As you can see from the example images above, the main difference between Code 39 and Code 128 is that Code 128 has a much higher data density than Code 39.

TIP: It is safest to use only numeric digits.
Most scanning machines can read both types of barcodes easily, but some scanners are unable to read barcodes that contains alphabetic letters.

TIP: If you don’t know which format to use, we recommend Code 128 because it is suitable for any size item/label. 

 

IMPORTANT: Code 128 and Code 39 should not be used for products that are for sale in retail stores (retail products need EAN barcodes).
