How does mail travel from state to state

In the United States, mail travels from state to state through a network of postal facilities and transportation systems managed by the United States Postal Service (USPS). Here's an overview of the process:

1. Collection: Mail is collected from post offices, mailboxes, and businesses across the country. This is done by postal carriers, who sort and bundle the mail into larger collections.
2. Sorting: The collected mail is taken to a local post office or a mail processing facility, where it is sorted by zip code, destination, and type of mail (e.g., first-class, priority, package).
3. Barcoding: Each piece of mail is scanned and barcoded with a unique identifier, which helps track its journey and ensures it reaches its destination efficiently.
4. Transportation: The sorted mail is then transported to a regional processing facility, often by truck or plane. This is where the mail is transferred to larger vehicles or aircraft for further transportation.
5. Regional Processing: At the regional processing facility, the mail is sorted again by zip code and destination. This is where the mail is prepared for transportation to its final destination.
6. Long-Distance Transportation: The mail is then transported to a national processing facility, often by truck or plane. This is where the mail is sorted and prepared for delivery to its final destination.
7. Delivery: The mail is finally delivered to its destination post office, where it is sorted and delivered to the recipient's mailbox.
