Shipper Generated Labels

Merchants may generate their own labels—commonly used in high-volume fulfillment centers or asynchronous workflows.

Required Label Elements

DashLink requires the following on every label:

1. Recipient name & full address​

Must be prominent and clearly readable.

2. Scannable barcode​

Barcode must represent the tracking code (external_delivery_id or pickup_reference_tag).

Supported barcode types:

  • Data Matrix
  • AZTEC
  • Code 128
  • Code 39
  • Code 93
  • CODABAR
  • EAN-13
  • EAN-8
  • ITF
  • UPC-A
  • UPC-E
  • PDF417

3. Tracking code​

  • 15–35 characters
  • Must be unique
  • Recommended: 3-letter alpha prefix (e.g., DLK for DashLink)

Label Recommendations (Strongly Suggested)

From the PDF's label guidelines:

  • Do NOT include other prominent barcodes on the label → scanners may read the wrong one
  • Include ship date to help operations identify old shipments
  • Include shipper name in upper-left corner
  • Avoid tiny fonts or cramped layout
  • Ensure barcodes have adequate quiet zone margins

When to use shipper-generated labels

Ideal for:

  • Asynchronous / batch workflows
  • Merchants with their own label-printing pipelines
  • Fulfillment centers with automated sortation equipment
  • Multi-carrier routing engines
