How many pieces of mail are lost each year

According to the United States Postal Service (USPS), the exact number of lost pieces of mail each year is difficult to determine, as it's a complex issue that involves various factors such as mail volume, processing efficiency, and customer reporting. However, I can provide some statistics and insights that might give you an idea of the scope:

  1. In 2020, the USPS reported that it processed over 142 billion pieces of mail, including letters, flats, and packages. (Source: USPS Annual Report 2020)
  2. According to a 2020 report by the Government Accountability Office (GAO), the USPS estimates that about 1.4% of mail is lost or undeliverable each year. This translates to around 2 billion pieces of mail. (Source: GAO Report 2020)
  3. A 2019 study by the market research firm, Pitney Bowes, estimated that the average household in the United States receives around 100 pieces of mail per year, with about 10% of that mail being lost or undeliverable. This would translate to around 1.4 billion pieces of mail lost or undeliverable annually. (Source: Pitney Bowes Study 2019)
  4. Another study by the marketing firm, Valpak, estimated that in 2018, around 4.3 billion pieces of mail were lost or undeliverable in the United States. (Source: Valpak Study 2018)

It's essential to note that these numbers are estimates and may vary depending on the source, methodology, and time frame considered. Additionally, the USPS and other mail carriers have implemented various measures to improve mail processing and reduce losses, such as using advanced tracking technologies and optimizing mail sorting and delivery routes.

In summary, while the exact number of lost pieces of mail each year is difficult to determine, estimates suggest that it could be anywhere from 1.4 billion to 4.3 billion pieces, which is a significant portion of the total mail volume processed annually.
