Signature instruction
Sur cet exemple : Signature required
Champ documenté / exemple de données
Signature requiredThe CN04 area includes an explicit signature-required instruction.
Vérifier avant utilisation
The signature instruction is printed outside the 13-character S10 identifier. It does not prove a signature was collected, establish live delivery status or mean that the RT or HK components encode a signature result. Check the issued label and applicable service conditions.

Additional non-S10 barcode
Sur cet exemple : Additional non-S10 barcode
Champ documenté / exemple de données
Additional non-S10 barcodeThe source explains that a second non-S10 barcode can coexist with the S10 identifier. It must not be mistaken for a second S10 tracking number.
Vérifier avant utilisation
The additional barcode is not a second S10 tracking identifier. Its presence alone does not establish a decoded payload, account, service code or accepted live shipment. Do not substitute it for RT011231107HK without documentation for that barcode and workflow.

Actual destination
Sur cet exemple : Melville SK S0A 2P0 CANADA
Champ documenté / exemple de données
Melville SK S0A 2P0 CANADAThe destination address supplies routing context. The HK suffix in the S10 number identifies the issuing authority.
Vérifier avant utilisation
Canada is the destination in this illustrated address; HK in the S10 identifier is the issuing authority. The address does not establish an internal depot or route token, actual transport mode, current booking or shipment status. Preserve the source redactions rather than reconstructing masked address details.
