usps overnight time cutoff

usps overnight time cutoff refers to the latest time a package can be accepted at a USPS location for guaranteed overnight delivery via Priority Mail Express. Most post offices have a cutoff time between 3:00 PM and 5:00 PM local time. Shipments dropped off after this time may be processed the next day, delaying delivery. Customers should confirm the exact cutoff with their local branch to ensure timely service. Meeting the deadline is essential for time-sensitive mail, especially for legal documents or critical e-commerce orders that require next-day delivery.
