How to become a postal worker?

To start a career as a postal worker, you need a high school diploma or GED and U.S. citizenship or permanent resident status. The postal service has qualifications you must meet to be eligible for hire. First, you must pass the post office written exam. The four parts of the test cover topics like memory and coding, address cross comparison, forms completion, and personal experience. You must also pass a criminal background check, undergo a drug test, and demonstrate that you are physically able to lift heavy mail sacks and crates.
