How to Work for the United States Postal Service (USPS)

First, you would need to apply through the USPS’s website. You would need to create an account before you can apply. The process is simple. You’re only required to input your first and last name, email, username, and password.

Requirements to Work at USPS

There are several qualifications you have to check in order to be eligible to apply to the USPS. After all, they are the second-largest employer in the United States. This already brings some competition. Therefore, you would need to pass the minimum requirements to work at the USPS.

  • Have to be at least 18 years old at the time of the appointment, or 16 years old with a high school diploma.
  • Be a United States citizen, permanent resident, or citizen of a U.S. territory.
  • Have recent employment history.
  • Ability to pass a criminal background check, drug screening, and medical assessment.
  • Residency requirement for background checks (proof of U.S. citizenship or other).
  • Safe driving record (if applicable).
  • Registered with Selective Service if applicable.

If you meet all of these minimum requirements, then you’re qualified to apply for the USPS. However, there are some other things you have to be aware of. Many postal service jobs require workers to stand for hours at a time. Unless you’re a driver. There may also be further requirements that you must meet depending on the job listing.

What is the Postal Exam 473?

The Postal Exam 473 is an entrance examination that the USPS requires you to complete depending on the job you applied for. This assessment is not available for every applicant. There will only be a limited amount of applicants who receive the invitation to take this assessment. Each job posting has a predetermined number of applicants that can be tested. Once the maximum is reached, no further invitations will be sent.

Updates on Postal Exam 473

There are other postal exams that have replaced it according to the appropriate job listing. The exam is not necessary for every job listing. However, it is required for over 70% of the USPS’s jobs. Here are jobs in the USPS that require you to pass a postal exam:

  • 474 – City and Rural Postal Carrier
  • 475 – Mail Handler and Mail Handler Assistant
  • 476 – Mail Processor
  • 477 – Customer Service Clerk
  • 955 – Mechanic and Technician

Depending on the job you applied for, your exam may be proctored, un-proctored, or both. If the exam is proctored, you will need to test at a USPS testing-approved facility. The span to complete this assessment ranges from three to seven days. The timeframe is dependent if it is being proctored or not. Make sure to give yourself enough time to prepare and study!

You can only take the exam once per job listing.

More on Exams

The following questions can be found in postal exams 474, 475, 476, and 477. Postal exam 955 is completely different from other assessments. Overall, you will be expected to answer questions based on personal experiences and work scenarios.

  • Work Scenarios: Tests your ability to work out an issue and to resolve them. These questions gauge your reaction to different scenarios.
  • Tell Us Your Story: Prompts questions based on your work experience and background.
  • Describe Your Approach: Formatted as a personality test based on how you approach daily tasks.

These three categories will appear on all aforementioned exams (with the exception of 955). Other than exam 474, all other exams will have an additional category that is different depending on the job you applied for. The Work Scenarios category has the least amount of questions, while the last category, Describe Your Approach, has about 56-79 questions.

While there is no time limit, you are still encouraged to give yourself a certain amount of time per question. Applicants with the highest scores will be invited to an interview much more quickly than someone who scored lower. The minimum score to pass is 70. Any lower, and you will be ineligible to continue. You can retake an exam after 12 months. If you score higher than the minimum, expect the USPS to take an interest in you much sooner than expected.

In order to take the postal exam, you will have to schedule an appointment to take it as an approved testing center. Remember that you have roughly three to seven days to complete it. So prepare wisely!
