If your mailer creates its own Receptacle IDs and labels using a non-GSS system, click the Scan Receptacle link to open the Scan Receptacle page.
On this screen, scan the receptacle label. The receptacle ID appears in the Receptacle ID field. Enter the Piece Count, Weight, and Package Shape for the receptacle. The Weight should be the net weight (gross weight minus tare weight) in pounds. These fields are required if your facility manifests its IPA and ISAL packages.
For manifesting mailers, when the submitted receptacle ID's foreign office of exchange maps to more than one destination country, you will be prompted to choose the destination country from the list.
Click the Add Receptacle button to add it to the shipment.
Each receptacle ID must be unique and consist of 24 characters comprising discrete, required pieces of information. GSS validates each portion of the receptacle ID, necessitating that the information included be both accurate and in the correct order.
The following table shows what information should be included at each position in the receptacle ID:
