The 72-hour window and the one-year rule: the two postal exam deadlines that cost applicants a year
Two rules decide more carrier, handler, clerk and window applications than any question on the exam. You have 72 hours from the moment the invitation is sent to finish the assessment, and if you don't pass, you can't retake that exam for a year. Both are published rules; both catch people who treat the email as something to deal with over the weekend.

The 72-hour window
- The clock starts when the invitation is sent, not when you open it. Check spam the day you apply, and add the official hiring and testing email domains to your contacts.
- The assessment takes about 30 to 45 minutes; one sitting is recommended but not required.
- If you apply to several jobs that use the same exam, finish within 72 hours of the first invitation. One completed assessment counts for all of them.
- Miss the window and you're no longer considered for that job. You can still apply to other postings.
- Not everyone who applies is invited, and postings say testing continues until capacity is reached, so apply the day a posting opens.
The one-year rule
- If you don't pass (70 is passing), you can't retake that same exam for one year (12 months) from your most recent attempt, and you won't be considered for jobs that use it meanwhile.
- You can take a different exam right away by applying to a job in another group: fail 474 and carrier jobs are closed for a year, but mail handler (475), mail processing (476) and customer service (477) jobs are not.
- A passing result is reused automatically for later postings that use the same exam until it expires (described as two years). A low pass follows you until then, so your first attempt matters.
- The one-year wait is a Virtual Entry Assessment rule. Other postal exams (955, for example) use their own retest dates.
What to do with the 72 hours
Plan to start within the first day, from a quiet room on a plugged-in computer with a stable connection, and do a short, timed practice test first so the format isn't a surprise. The exam isn't something to study for in the sense of memorizing answers; it's something to show up prepared, rested and unhurried for, because you only get one attempt a year.

Questions people ask
- Does the 72 hours start when I open the email?
- No. It starts when the invitation is sent.
- Can I apply again right after failing?
- Not for a job that uses the same exam; that's closed for a year. You can apply to a job that uses a different exam immediately.
- If I pass, do I have to take the exam for every posting?
- No. Your result is reused automatically for later postings that use the same exam until the expiration date on your results.
- What if something goes wrong technically during the exam?
- Use the help or support contact in your invitation, and do it while there's still time on your 72 hours. That's one more reason not to start on the last day.
