I have tried that, but doesn’t give me the full tracking number.
“Upcoming Changes: Limiting display of reference number tracking details for improved security.
UPS is changing how the reference number tracking results are displayed to provide additional protection:
Tracking details will be mostly masked with only basic reference number tracking details available.
Senders that have saved the shipment's account number as a payment method in their profile, or in their company profile, will see the full tracking details.”
