If your QR code won’t scan at the post office, shows as “invalid,” or you don’t have a printer, you’re not alone. Below are steps you can try to resolve this issue and a fallback solution.
What you can try first
Switch to a stable Wi-Fi connection
QR codes generated over mobile data may fail to sync. Use a reliable Wi-Fi network and regenerate the QR code.Restart the PangoBooks app
Completely close and reopen the app, then try creating the QR code again.Generate the QR code just before shipping
Create it right before you visit the post office.
Please note that labels destined for military and diplomatic addresses, as well as some Territories and Freely Associated States, cannot be converted to QR codes as they require a customs form. In these cases, we recommend adding your own tracking number!
If it still doesn’t work: add your own tracking
If generating a working QR code doesn’t succeed after trying the steps above, you can bypass the QR entirely by using your own USPS Media Mail label and tracking number.
Purchase a USPS Media Mail label and obtain a valid tracking number.
In your PangoBooks account, go to Sold Books.
Find the order you need to update.
Scroll to the bottom of that order and click Add My Own Tracking Number.
When you do this, the original label becomes void, and the original label amount is released back alongside your PangoBooks earnings.
Using your own tracking ensures your buyer can follow the shipment without relying on the QR code.
