Occasionally when sending international packages customs UPS tracking will show something along the lines of:
"POWER OF ATTORNEY DOCUMENTATION IS MISSING AND IS REQUIRED FOR CLEARANCE. WE'RE WORKING TO OBTAIN THIS INFORMATION."
This basically means the receiver of the package must authorize UPS on their behalf to manage that package through customs.
Usually UPS will contact the receiver directly to resolve this issue.
Providing UPS with Authorization
In order to provide authorization to UPS the receiver (you) must fill out the following form: https://www.ups.com/content/us/en/shipping/international/forms/power_attorney.html
On Step 3 Shipper Number the receiver should use Printfection's shipper number of R44Y99.
Once the form has been filled out the receiver (you) must either email the form to the UPS agent who contacted them or fax the form to the fax number provided at the bottom of the form (we know, fax sucks).
Once UPS has received the form they will then work to move the package through customs or follow up with the receiver if any additional information is needed.
