Barcodes for Logistics Labels
Encode carton IDs, ASN strings, and job tickets for dock and line scanners.
Logistics label barcodes encode carton IDs, ASN strings, and routing data for dock scanners and conveyor imagers. Code 128 carries dense alphanumeric payloads; ITF-14 marks standard retail cases when GTIN-14 is required. Build labels in the Code 128 generator and ITF-14 generator, then test with warehouse hardware.
Why teams use this
Mislabeled cartons misroute inventory, trigger chargebacks, and stall cross-docks. Labels must survive rain, friction, and repeated scans across hub sortation.
How to implement it
Use thermal transfer on corrugated, standardize field order in Code 128 strings, and mirror label data in your TMS/WMS integration tests.
- Document delimiter characters between SSCC, PO, and SKU fields.
- Print duplicate labels on opposing case faces when conveyors flip cartons.
- Validate ASN barcodes against EDI 856 test environments.
- Replace worn printheads before bars lose edge definition.
- Scan samples at inbound and outbound lanes before go-live.
Common mistakes
Mixing Code 39 guns with Code 128 labels silently fails picks. Another mistake is truncating SSCC check digits during manual edits. Do not use retail EAN art on logistics-only cartons without partner approval.
Tools to get started
Use Code 128 with shipping cases and warehouse labeling for end-to-end flows.
