Both of USPS's entry doors into carrying mail - City Carrier Assistant (CCA) and Rural Carrier Associate (RCA) - run through the same gate: Postal Exam 474, 70% to pass, same one-year lockout if you fail. The jobs on the other side of that gate, though, are more different than the titles suggest. Here's what official USPS sources actually document about each.
What each job actually is
CCA - City Carrier Assistant. USPS describes CCAs as "full-time alternates for regular letter carriers": sort, lift, and push moderate to heavy loads, deliver an assigned city route, collect mail, handle postage due, and work "indoors and outdoors in all weather: rain, snow, cold and heat" (their words, not ours). City routes mean denser stops, more walking loops, and USPS vehicles.
RCA - Rural Carrier Associate. Same core: sort, deliver, collect along a rural route. Two documented differences. First, RCAs also sell - stamps, stamped paper, money orders - because on a rural route, the carrier often is the post office. Second, per the USPS Inspector General, some RCA postings require using your personal vehicle. If your car can't do a mail route daily, read the posting carefully before falling in love with the job.
The honest part nobody puts in recruiting ads
The same federal audit surveyed people who left. 45% of departing RCAs said the job was more physically demanding than they expected, and most delivery facilities expect carriers to walk portions, if not all, of their routes. CCA turnover ran 67% in fiscal year 2023. Neither number means the jobs are bad - both are real paths to career USPS positions - but both numbers say the same thing: people quit when the day-to-day surprises them. The Realistic Job Preview video at the start of your 474 exists precisely because of this. Watch it like it's information, not an ad.
How to actually choose
- Check what's posted near you first. New postings typically go up Fridays and close within days. Your real choice is often "which one is hiring here", not an abstract preference.
- Have a reliable car you'd use for work? RCA postings that need a personal vehicle become an option; without one, filter for CCA or for RCA postings that provide a vehicle.
- Want the retail flavor too? RCA includes selling services; if you'd rather purely deliver, that leans CCA.
- Check pay on the posting itself. Carrier pay is set by union contracts (NALC for city carriers, NRLCA for rural) and changes with each agreement, and any specific number we print today will be stale. The posting's number is the real one.
Quick answers
Do CCA and RCA take different exams?
No, both take Postal Exam 474 (Virtual Entry Assessment MC). One passing result covers City Carrier, Rural Carrier, CCA, and RCA applications for roughly two years.
Can I apply to both at once?
Yes. If both are posted in your area, apply to both; you take the 474 once (within 72 hours of the first invitation) and the result serves every carrier application.
Do RCAs always need their own car?
No, but some postings require it, and the requirement appears in the posting itself. Read before applying.
Which pays more?
Pay is set by the respective union contracts and updates with each agreement, and the honest answer is: whatever the current postings in your area say. Check the posting, not a blog.
Is either a path to a career position?
Yes, both are the standard pre-career entry roles for their routes; CCAs are explicitly "full-time alternates for regular letter carriers" per USPS.
