The most common cause of no tracking records is incorrectly typed tracking number. It is advised to check with the sender if you are not sure what the number is. Besides, it takes up to 24 hours for a new package to show up in the system.
It is advised to check with local office for accurate results, because the hours of delivery vary by product and location.
