United States Postal Service 


The United States Postal Service (USPS), also referred to as the US Post Office, or simply the Post Office, is a federal institution that is independent of the government in that they are self-supporting, have a Board of Governors and rely on executive management usps_logorather than congressional legislation to function. The USPS delivers more mail to addresses in a larger geographical area than any other post, accounting for 40% of the world’s mail delivery. In 2014, the USPS….

  • Processed 155,400,000,000 pieces of mail,
  • Changed 34,400,000 addresses,
  • And delivered to over 153,900,000 locations nationwide.

First class mail alone accounts for over $28 billion of a more than $1 trillion mailing industry that employs more than 8 million people. Needless to say, the USPS has earned it’s place in the “Big Three”. 

The most common issues I deal with or questions I have regarding the Post Office:

  • Just because it’s a single sheet of paper, rather than an envelope does NOT make it a post card (read more on my article about postcards.)
  • Stamps are 49¢ but I do not sell any in Mail Services.
  • A good rule of thumb for figuring out if your letter needs one or two stamps… if you can easily fit the envelope in between the tines of a fork (without damaging the envelope. Well, or the fork, I suppose) and it stays, then you’re probably safe. I’m always able to weigh things just to make sure too.
  •  And yes, mail is still delivered by Mule Train, but only in Arizona. Okay, that’s not a commonly asked question, but it’s interesting, right?

The post office excels at large amounts of mail being sent accurately and efficiently for a fair price. So, if you have a birthday card, and on-time payment, a package to send that has little to no value… the USPS is going to give you the most bang for your buck in my opinion.
