Post office

A post office is a public facility and a retailer that provides mail services, such as accepting letters and parcels, providing post office boxes, and selling postage stamps, packaging, and stationery. Post offices may offer additional services, which vary by country. These include providing and accepting government forms, and processing government services and fees. The chief administrator of a post office is called a postmaster. During the 19th century, when the postal deliveries were made, it would often be delivered to public places. For example, it would be sent to bars and/or general store. This would often be delivered with newspapers and those who were expecting a post would go into town to pick up the mail, along with anything that was needed to be picked up in town.

Before the advent of postal codes and the post office, postal systems would route items to a specific post office for receipt or delivery.
