Thanks for checking in with us about this. Although we do intend to update our USPS shipping label service to support the creation of Parcel Select shipping labels with a future site update, I am unable to
provide you with a specific date on which this option will be available at this time.
At this point, I expect that we will most likely be able to offer Parcel Select shipping labels at some point this spring and I will update this thread again to let you know when the feature has been added or any other important details become available.
If you need any further assistance with your account, please feel free to contact our Customer Support team by mousing over the “Help” tab and selecting the “File Support Case” option.
