What did Benjamin Franklin have to do with Zip codes?

Benjamin Franklin is often associated with the early development of the postal system in the United States, which laid the groundwork for modern mail delivery, including the use of zip codes. In the 18th century, he served as the first Postmaster General, improving mail service and establishing postal routes. While he did not create zip codes, his efforts in organizing the postal system eventually contributed to the need for a more efficient way to sort and deliver mail, leading to the introduction of zip codes in the 20th century.
