Here is a thing most prep sites will not tell you, because it is bad for selling two products: the 475 and the 476 are nearly the same exam. Same four sections, same rules, same 70% bar, both including Check for Errors. The real choice between them is not about the test at all. It is about which plant job you want, and that difference is real.
Same test structure, different day
Mail Handler (475): the muscle. USPS's duty list: loading, lifting, and carrying moderate to heavy mail from trucks and sorting equipment, separating bulk mail, loading trucks, operating machinery, rewrapping damaged parcels. You live at the docks and the staging floor.
Mail Processing Clerk (476): the machine operator. Duty list: sorting mail using automated equipment, keeping the sorting operation organized and fed, occasional public window service for non-financial transactions, prolonged standing. You live at the machines.
Both are physical, both are plant-based, both often run overnight, and both USPS duty lists warn about weight and standing in nearly the same words. The federal hiring audit clocks both pipelines at roughly a month from application to start.
How to actually choose
- Check what is posted near you first. Postings go up and close within days; your real choice is usually whichever plant job is hiring in your area this month.
- Prefer trucks, variety of motion, and heavier lifting? That is the handler's day.
- Prefer running equipment with a steadier station and rhythm? That is the clerk's day.
- Applying to both is allowed and often smart: they are separate exams with separate results, and preparation for one is nearly complete preparation for the other.
The strategic angle nobody mentions
Because the lockout rule is per exam version, the two plant exams back each other up. Fail the 475 and the 476 is open immediately, with the same section formats you just practiced and a different pool of jobs behind it. A bad day on one exam does not have to cost you the plant.
Quick answers
Does passing the 475 count for 476 jobs?
No. Results are per exam version. One passing 475 covers mail handler postings for about two years; 476 postings need their own result.
Which pays more?
Pay is set by the applicable union contracts and updates with each agreement, and the posting in front of you carries the real number. Check the posting, not a blog.
Is one exam easier?
USPS publishes no pass rates for either. Structurally they are the same four sections, so "easier" mostly means "the job you would rather preview honestly".
