Routing Label vs Shipping Label: Key Differences And When To Use Each

Routing Label A carton, pallet, or shipping label used to communicate the identification, routing, receiving, or compliance information described by 'Routing Label'.

The term "shipping label" is often used interchangeably with routing label, but operationally the two serve different priorities. A shipping label focuses on the carrier and postage—who pays, how to route the parcel from origin to destination, and what service to use. A routing label emphasizes internal and consignment movement: matching pallets to ASNs, routing within multi-tenant warehouses, and providing receiving staff with the identifiers needed to process goods. Distinguishing the two helps prevent data gaps that cause delays, missed scans, or chargebacks.

Primary Purpose Differences

Shipping labels primarily enable movement through the carrier network. They display carrier account numbers, service codes, and the carrier’s tracking number. Routing labels primarily enable movement through the supply chain and the receiving process at the consignee: they contain SSCCs, ASN references, retailer location codes, and internal handling instructions.

Who Uses Each Label

Carriers, sort facilities, and postal networks use shipping labels. Warehouse staff, 3PL sortation teams, cross-dock operations, and retailer receiving docks use routing labels. In many operations both labels are required: a shipping label for the carrier and a routing label for the consignee's inventory systems.

How The Data Differs

• Shipping Label Data: Carrier account, carrier tracking number, weight, service level, and postage or freight bill indicators.
• Routing Label Data: SSCC or pallet ID, PO/ASN references, consignee location code, content descriptors, and handling instructions.

Examples Of When Both Are Needed

If a 3PL ships Consolidated LTL for multiple retailers, every pallet needs a routing label (so each retailer knows which pallets belong to them when breaking the load) and a shipping label or freight bill for the carrier (so drivers can route trailers and billing is correct). For direct-to-consumer parcels, a single shipping label often suffices because the parcel’s carrier tracking and address are both carrier- and consignee-facing.

Practical Risks Of Confusing The Labels

Using only a shipping label when a routing label is required can lead to missed matches at receiving, causing put-away delays or rejected shipments. Using only a routing label can leave carriers without the payment or service information they need, resulting in refused pickups or re-billing. Common issues include unreadable barcodes due to poor print settings, missing SSCCs, and label placement that interferes with carrier scanning software.

How Systems Should Support Both

ERP, WMS and TMS platforms should be configured to print both label types when required and to validate label fields before print. Rules should enforce which fields are mandatory depending on destination, carrier, and trading partner agreements. Integrations with carriers reduce duplicate manual entry; GS1 identifiers and agreed code lists reduce exceptions at consignee receiving.

Best Practices

• Standardize Label Formats: Define when a routing label is required and the data it must contain for each trading partner.
• Agree With Trading Partners: Confirm the identifier list (SSCC, PO, ASN) and barcode symbology with the consignee and carrier before volume shipments.
• Automate Validation: Use WMS/TMS validation rules to prevent labels from printing with missing or mismatched data.
• Label Placement: Ensure both labels can coexist on a pallet/carton without obscuring each other; designate primary scannable faces.

In short, the Routing Label and the shipping label each play complementary roles: routing labels drive internal logistics and receiving efficiency, while shipping labels enable carrier routing and billing. Using both correctly avoids exceptions and keeps goods moving on schedule.
