Eligibility, Requirements, and Benefits

The official U.S. postal system was created during the American Revolution, primarily to facilitate the delivery of important messages among various divisions of the Revolutionary army. Meeting in July of 1775, the Second Continental Congress named Benjamin Franklin, who had been instrumental in devising the system’s framework and recommending it to the Congress, as the postal system’s initial Postmaster General.

Today, the U.S. Postal Service (USPS) is one of the nation’s largest civilian employers, currently employing more than 700,000 people in career positions throughout the country. A career position with the Postal Service can be rewarding work: the compensation and benefits packages are among the best you’ll find anywhere, and you’ll enjoy the additional satisfaction of knowing that you are part of a long tradition of providing vital services to the country and its people.

Understandably, Postal Service employment is attractive to many, many people, and the market for Postal Service career jobs is very competitive. Application exams such as Test 473 are one means that the Postal Service uses to screen applicants and identify those who are best qualified for various positions. Test 473 is officially known as Test 473 for Major Entry-Level Jobs and is also referred to as the 473 Battery Exam. (It replaces the old 470 Battery Exam.)

If you’re applying for a job that requires you to take one of the exams given by the Postal Service, it’s imperative that you gain a competitive edge by preparing thoroughly for the exam. This is especially true for Test 473 because more applicants take this exam than any of the other Postal Service exams. .

Postal Jobs Requiring Test 473 Scores

Applicants for most types of delivery, distribution, and retail jobs with the USPS must take Test 473 (or Test 473-C for City Carriers). There are four positions that fall into this category:

  • City Carrier
  • Mail Processing Clerk
  • Mail Handler
  • Sales, Services, and Distribution Associate

Applicants for permanent, or career, positions as City Carrier, Mail Processing Clerk, Mail Handler, or Sales, Services, and Distribution Associate must take and pass Test 473 in order to qualify for these positions. New employees in these four positions are usually paid an hourly wage and work on a somewhat flexible schedule, which varies depending on the work flow, especially the volume of mail during a particular day or season. Following is a brief description of each of these four positions.

Note: The Postal Service also offers temporary, or so-called casual, job positions in the same four categories. A casual job position may last from a few weeks up to a maximum of 90 days, usually during the Christmas holiday season. Applicants for casual positions do not need to take Test 473 or any other exam.
