Finding the correct Mount Vernon USA zip codes can get confusing quickly. Because multiple states feature cities named Mount Vernon, looking up a postal code without checking the state often leads to misaddressed mail or shipping delays.
Whether you're mailing a package to George Washington's historic estate in Virginia or handling logistics for a business in Ohio, Illinois, New York, Washington, or Iowa, you need accurate, state-by-state postal data. This reference breaks down every major Mount Vernon across the United States, listing their exact ZIP codes, regional contexts, and delivery boundaries.
Mount Vernon, New York Zip Codes
Located in Westchester County just north of New York City, this densely populated city uses multiple postal codes to manage its heavy mail volume.
- 10550: Covers the western and central sections of the city near the border with Yonkers.
- 10552: Serves the eastern residential neighborhoods and commercial strips.
- 10553: Handles the northern portions of the city up toward Eastchester.
- 10551: Reserved strictly for Post Office box allocations within the municipality.
If you're sending legal or financial documents to this area, double-check street numbers. Parts of the adjacent neighborhood of Bronxville (such as ZIP code 10708) directly border Mount Vernon addresses, making precision critical for prompt delivery.
Mount Vernon, Washington Zip Codes
Situated in Skagit County in the Pacific Northwest, this agricultural and commercial hub relies on two primary standard ZIP codes.
- 98273: Covers the southern and eastern portions of the city, including wide rural expanses stretching toward Skagit flats.
- 98274: Encompasses downtown Mount Vernon and the northern residential sectors up toward Clear Lake and Burlington fringes.
Local businesses shipping agricultural products or retail goods across the Pacific Northwest often use these codes in conjunction with automated USPS Lookup tools to ensure automated sorting systems route freight without manual intervention.
Mount Vernon, Ohio Zip Codes
Serving as the county seat of Knox County in central Ohio, this community keeps postal routing straightforward.
- 43050: This is the primary standard ZIP code covering the entirety of the municipality as well as surrounding townships.
Because it's a single-code city, mail routing rarely gets complicated by overlapping boundaries. However, matching street names to the correct county remains important for local courier services operating outside standard postal routes.
Mount Vernon, Illinois Zip Codes
Located in southern Illinois within Jefferson County, this regional crossroads utilizes a single main postal designation.
- 62864: Covers the entire city along with outlying areas like Summersville and local industrial parks near the Mount Vernon Outland Airport.
When filling out freight bills or ecommerce fulfillment software, make sure to enter the exact ZIP+4 extension if you're shipping to larger commercial facilities within this zone to speed up local sorting.
Mount Vernon, Virginia and Iowa Zip Codes
Two other notable locations carry the name, each serving distinct geographic and cultural purposes.
- Mount Vernon, Virginia (22121 / 22309): Home to George Washington's historic estate. While the estate and surrounding unincorporated Fairfax County communities use specific local codes like 22121 and 22309, mail is closely tied to Alexandria regional distribution centers.
- Mount Vernon, Iowa (52314): Located in Linn County and home to Cornell College, this eastern Iowa town operates entirely under the 52314 postal code.
Common Addressing Mistakes to Avoid
Mailing errors happen most frequently when senders rely on autocomplete tools that guess the state based on partial text inputs. Keep these tips in mind to protect your mail delivery rates:
- Verify the state abbreviation: Mixing up NY, OH, IL, WA, IA, and VA will cause immediate misrouting.
- Check for PO Box exclusivity: Some codes are designated solely for post office boxes rather than street delivery.
- Use official databases: Always cross-reference unfamiliar addresses using the Official USPS Postal Explorer rather than generic mapping directories.
