Marietta Post Office Phone Number The Trick Locals Actually Use
The Marietta post office phone number depends on which Marietta you mean: in Marietta, Georgia, the main USPS location at 257 Lawrence St NE can be reached at (770) 590-9771, while the Marietta, Ohio post office at 275 Front St uses (740) 373-0737. Both locations also list the USPS customer service line at 1-800-ASK-USPS (800-275-8777) for general help.
Why the number is harder to reach than expected
People searching for the Marietta post office often run into a simple problem: there is more than one Marietta in USPS databases, directories, and local listings, so the first result is not always the right office. The Georgia and Ohio branches have different phone numbers, different hours, and even different service patterns, which makes a quick call less straightforward than most users expect.
That confusion is amplified by the way USPS location pages, third-party directory sites, and review platforms present local office details. Some listings highlight retail hours, others highlight lobby access, and some surfaces are outdated or mismatched, so the same search can produce several conflicting "Marietta" entries before you find the right branch.

Hours and access
The Georgia Marietta office at 257 Lawrence St NE lists weekday retail hours of 8:30 AM to 6:00 PM, Saturday hours of 8:30 AM to 1:00 PM, and Sunday closure. The Ohio Marietta office at 275 Front St lists weekday hours of 8:00 AM to 5:30 PM, Saturday hours of 8:30 AM to 1:00 PM, and Sunday closure.
Hours matter because many callers are trying to confirm same-day services, and a closed lobby or limited counter schedule can make a phone inquiry feel urgent. In practical terms, the busiest window is usually late morning through early afternoon, when customers are checking package status, holiday mail timing, and post office box access.
Best way to reach them
- Confirm which Marietta you need: Georgia or Ohio.
- Use the exact street address to match the correct office listing.
- Call the local number first for branch-specific questions.
- If you need general USPS help, call 1-800-ASK-USPS (800-275-8777).
- If the line is busy, check whether the issue can be handled online through USPS tracking or location tools.
Why search results vary
Search results for the Marietta post office can vary because directories often index multiple branches, nearby ZIP codes, and user-submitted business data all at once. That is why one result may show a Georgia address, another may show Ohio, and a third may route you to a national USPS contact page instead of the local counter.
Third-party listings can be useful for a quick phone lookup, but they are not equally reliable for hours or service updates. The most dependable pattern is to match the office by street address first, then confirm the phone number, then check hours before you call.
"The fastest way to avoid a wrong number is to verify the street address before dialing."
