Issuing a Zonos Postpaid Mail Slip (後納郵便物等差出票)

By saving your Yu-Bin Biz Card number (Japan Post's ゆうびんビズカード番号) in your Zonos account settings on the "Carriers" screen and then issuing your shipping labels, you can generate a postpaid mail slip that reflects your shipping label data.
＊ Customers who wish to pay postage (shipping charges) via Japan Post's postpaid billing are required to submit a postpaid mail slip when sending international mail items.
 

Creating a Postpaid Mail Slip

Follow these steps to create a postpaid mail slip:

1. After finishing your label creation work for the day's shipments, go to the Report in the Ship&co app, and select the Zonos icon's postpaid slip (後納差出票) option in the "Create a report with" section.
2. A PDF postpaid mail slip will be generated, reflecting the history of Zonos Japan Post international mail labels issued since your last postpaid slip was created. Click "Open report" to download and print it.

Notes:

• For customers who were already using Zonos before the update released on the night of July 14, 2026: Any Zonos label history created before you saved your Biz Card number in Ship&co's "Carriers" screen > Zonos settings will not be reflected on the postpaid slip. 
   
• Each slip covers all label history not yet included in a previous slip (excluding labels voided after issuance). For example, if you skip creating a slip for one day's labels, the next slip you create will include two days' worth of history. Please also note that only labels created within the last 7 days are eligible to be included — if a label record is not reported within 7 days of creation, it will no longer appear in any future slip. We recommend creating a slip every day after finishing that day's shipping work.
   
• Each postpaid slip generated can include up to 250 entries. If there are more than 250 entries to ship at one time, please click the "後納差出票" button as many times as needed.
   
• There is no edit function. If corrections are needed, please cross out the entry by hand with a line.
   
• The "Sender's Address" (ご依頼主住所) field that appears on page 2 and onward of the postpaid mail slip is always left blank due to a limitation of our integration partner's system (API), and cannot be configured to print. If needed, please fill it in by hand or with a stamp after printing. That said, the shipping labels you create in Ship&co for EMS, international parcels, etc automatically include a "Sender's Copy" and "Accepting Post Office Copy" on the label itself. Since these are always generated automatically along with the label, submitting them together with your labels means you do not need to separately print or submit the list-style pages (page 2 onward) of the postpaid mail slip to the post office.

*Creating a postpaid mail slip is not a billable Ship&co usage item.
