Do you use our standard labels from the portal? Then you don't need to do anything — these automatically meet all requirements.
Do you use your own labels? Make sure your labels meet the conditions below to avoid delays.
1. Required information on the label
To ensure correct delivery, the following details must be clearly readable on the label:
- Recipient name.
- Delivery address: Street name, house number (including additions), postal code and city.
2. Barcode requirements
The barcode is essential for scanning your shipment in our sorting center.
- Type: We use Code 128C as our standard. Other formats cannot be guaranteed and must be tested first.
- Unique: The barcode/shipment number must be unique (do not reuse old numbers).
Make sure to send this barcode value in the “order_reference” field. - Print quality: The print must be sharp and in black and white. Ensure sufficient white space between the bars and around the barcode.
3. Size and dimensions
- Standard size: We use the standard shipping label size 102mm x 152mm (also known as 4" x 6" or A6).
- API response: The API always returns a link to the standard Trunkrs label (PDF format).
