Royal Mail requires you to create and print a Sales Order Summary, which you must then hand to the driver who picks up the parcels.
Important
Once you generate a Sales Order Summary, the labels included in it cannot be voided through ShipStation.
-
View the Open End of Day section.
You should now see your shipment count for the current date.
-
Click Close Shipments for the Royal Mail line item.
-
Click Close All, or select the desired shipments and click Close Selected.
Shipment Closing Limitations
You can close up to 500 shipments at once.
You can only close out past or current day shipments using the End of Day process. You cannot close shipments with dispatch dates in the future.
Repeat steps 4 - 5 if you need to close additional shipments.
-
Click the Print Selected button to print out the Sales Order Summary.
This will transmit your shipment information to Royal Mail electronically so you can be properly invoiced. Be sure to hand over the printed form to the driver or when you drop off your day's shipments.
Custom forms will print with the label for your international shipments.
ShipStation does not provide CN22 forms, only CN23. However, CN23 forms are sufficient for both low and high value shipments.
If there are too many different content types to fit on one page, the CN23 automatically extends to an additional page.
RoyalMail requires customs declarations for Channel Islands shipments. However, RoyalMail will not produce these forms if the country code is GB. Change the country code to IM, GE, or JE and then the proper forms will be included with the label.
Remember these points about ShipStation's integration with Royal Mail:
ShipStation cannot display estimated rates for Royal Mail services, as Royal Mail does not currently allow third-party apps, like ShipStation, to connect to their Rates API.
Address line has a character limit of 35.
Only Label Message 1 is supported. It has a character limit of 20.
You must set pickups (daily and other schedules) within Royal Mail, not in ShipStation.
-
While ShipStation does display a tracking number for shipments that include tracking, Royal Mail tracking events do not update in ShipStation. All tracking must be done on the Royal Mail tracking page. This also means the following ShipStation features cannot be used with Royal Mail services:
Delayed marketplace notifications
Delayed customer email notifications
Delivery email notifications
Branded Tracking Page
-
To create return labels, Royal Mail must approve you for at least one of the following services:
Tracked Returns 24 - TSN
Tracked Returns 48 - TSS
Royal Mail's connection pop-up does not validate your input. If you enter incorrect details into the fields, Royal Mail will contact ShipStation during the “pending” phase. If this occurs, ShipStation will then contact you so you can re-enter and resubmit it to Royal Mail.
Here are some common issues, potential causes, and troubleshooting tips.
Issue |
How to troubleshoot or resolve |
---|---|
Error submitting End of Day: "Error transmitting to OBA. Details: Access Denied (not authenticated)" |
If you receive this error message, it may indicate that you have a 'Pre-paid' Royal Mail account. This type of account cannot be accessed via a third-party shipping platform and thus is not supported. Direct any questions to Royal Mail. |
Error submitting End of Day: "Attempting to divide by zero" |
This means you are missing customs declarations information for one of your orders. Check the customs declarations for the orders contained in the End of Day to ensure they include all the required information: Description, Quantity, Value, Content Type, Country of Origin. |
Error on getrate/createlabel: "Royal Mail: The given key was not present in the dictionary" |
This error typically means that when you attempted to get a rate or create a label you selected Small Parcel for an international shipment. The package type Small Parcel is only available for domestic UK shipments. To correct this error, select the Parcel package type. If this option isn’t available in the drop-down menu, you likely have disabled the Parcel package type in your ShipStation account. Re-enable Parcel as a package type by going to |
