In the United States, free city delivery did not start until 1863. Prior to that, letters had to be mailed at the post office and picked-up at the post office, unless the sender or recipient paid an extra 1˘ or 2˘ for semi-official post office carrier service to or from the post office, or used a private local post.
The cover below used a private local post, Messenkope's Union Square Post Office, to carry the letter to the post office.
