How many letters are mailed each day

According to the United States Postal Service (USPS), the exact number of letters mailed each day is difficult to determine, as it varies depending on the day of the week, season, and other factors. However, I can provide some statistics on the volume of mail processed by the USPS:

• In 2020, the USPS processed over 142 billion pieces of mail, which includes letters, flats, and packages. (Source: USPS Annual Report 2020)
• On average, the USPS processes around 500 million pieces of mail per day. (Source: USPS Fact Sheet)
• In 2020, the USPS delivered over 143 billion pieces of mail, which includes letters, flats, and packages. (Source: USPS Annual Report 2020)

To give you a better idea, here's a breakdown of the average daily mail volume in the United States:

• Letters: around 200-250 million per day
• Flats (envelopes, catalogs, etc.): around 150-200 million per day
• Packages: around 100-150 million per day

Keep in mind that these numbers are estimates and may vary depending on various factors, such as holidays, weather, and economic conditions.
