Request a specific range of barcodes for use in your shipping processes.
You can use this endpoint to create your own number ranges and use them for generating the tracking numbers provided for offline barcoding shipments. This means that you do not need to integrate with the Royal Mail system to generate the barcode ranges.
Note: Offline Barcoding is only available if it has been activated on your customer account in the GUI.
