Test 473 is an entry-level test designed by the U.S. Postal Service (USPS) to measure general aptitude and suitability for certain types of postal work. It is not a test of factual knowledge.

Test 473 and Test 473-C are identical exams; in other words, they are one and the same test. Sometimes the test is administered only to fill City Carrier positions, in which case the exam is called Test 473-C. So the C stands for “City Carrier.”This article will answer most of your questions about Test 473. First, you’ll familiarize yourself with the format and various parts of the exam.

Note: Since Test 473 and Test 473-C are exactly the same, we’ll refer to both simply as Test 473 throughout the rest of this article.

The following is a brief description of each of the exam’s four parts.

Part A: Address Checking

Part A will present 60 correct addresses and ZIP codes, numbered 1 through 60. To the right of each address and ZIP code, another address and ZIP code will appear. The two should be the same, but the one on the right might contain one or more errors; in other words, it might not match the correct address exactly. Your job is to determine whether there are any errors and, if so, whether the error is in the address, the ZIP code, or both.

For each of the 60 items in Part A, you select one of four answer choices: (A) if the address and ZIP code are exactly the same, (B) if there’s a difference in the address only, (C) if there’s a difference in the ZIP code only, or (D) if there’s a difference in both the address and the ZIP code.
