Situated in Marathon, the Marathon Post Office at 5171 Overseas Highway plays a crucial role for residents and visitors alike, especially those residing in Key Colony Beach and the neighborhoods surrounding Sombrero Beach Road. This particular stretch of the Overseas Highway, just south of the intersection with 53rd Street, sees heavy traffic from both locals heading to Publix for groceries and tourists exploring the Florida Keys. The post office, more than just a place to mail letters, offers vital passport application and renewal services, primarily serving families, retirees, and seasonal residents in the area. Marathon, known as the heart of the Florida Keys, has a unique character. The Marathon Post Office serves a diverse demographic, from Conch locals whose families have been here for generations, to snowbirds escaping the northern winters, and a growing number of younger families drawn to the area’s laid-back lifestyle and excellent fishing. A significant portion of the local economy depends on tourism and fishing, so quick and efficient passport services are essential for those working on charter boats or in the hospitality industry. Its position on the Overseas Highway makes it easily accessible, though parking can sometimes be a challenge, especially during peak tourist season. The Marathon Post Office is within a short walk of several landmarks, including the Marathon Community Park located a few blocks away on 36th Street and the Marathon City Hall, which often hosts local events. The Marathon area’s history is deeply rooted in the railroad era. Before the Overseas Highway, Flagler’s Railway connected the Keys, and Marathon was a key stop. While the railway is long gone, its legacy lives on in the names of streets and the town’s overall character. The Post Office itself, constructed in the late 1970s, has undergone renovations over the years to keep up with the growing demands of the community. As a designated passport acceptance facility, the Marathon Post Office helps facilitate international travel for its residents. Unlike larger cities with dedicated passport agencies, this post office provides a more personal touch, with staff members often knowing many of their customers by name. The staff are skilled in guiding applicants through the complex paperwork involved in the passport application process. The Marathon Post Office provides more than just standard mailing and shipping services. The facility also offers services such as money orders, PO boxes, and notary services. This comprehensive array of services ensures that the Post Office remains a cornerstone of the Marathon community. The local branch also handles mail forwarding for the significant seasonal population that migrates between Marathon and northern states each year. This task is often complex, requiring careful attention to detail to avoid misdirected mail. The Marathon Post Office is integral to the social fabric of Marathon. Its role in providing essential communication and identification services continues to be essential to the community’s well-being. The branch’s commitment to excellent customer service underscores its critical role in the daily life of Marathon residents and visitors.

Located at MARATHON POST OFFICE at 5171 OVERSEAS HWY. Easy access from major highways.
Parking at the Marathon Post Office can be somewhat limited, especially during the peak tourist season between December and April. The facility has a dedicated parking lot directly in front of the building, offering approximately 25 spaces. These spaces are free of charge but tend to fill up quickly. During busier times, especially around midday, you may need to circle the lot a few times or wait for a spot to open up. There’s no street parking directly along the Overseas Highway in front of the post office. However, there are some limited side street parking options further down towards 51st Street, about a block away. Be mindful of parking regulations and avoid blocking any driveways or fire hydrants. During the hotter months, the asphalt in the parking lot can get quite hot, so wearing appropriate footwear is recommended. For those who anticipate difficulty finding parking, arriving early in the morning or later in the afternoon may increase your chances of securing a spot. Consider arriving 10-15 minutes before your scheduled appointment to allow time to find parking and avoid rushing. There are no dedicated disabled parking spaces, so people with accessibility requirements may have to walk a short distance from the closest available spot.
Public transportation options to the Marathon Post Office are limited but available. The Monroe County Transit, specifically the Lower Keys Shuttle, provides bus service along the Overseas Highway (US 1). Route 1 stops near the post office. The nearest bus stop is located at the intersection of Overseas Highway and 52nd Street, approximately a 5-minute walk (0.2 miles) from the post office. The bus operates on a fixed schedule, with service frequency ranging from every 60 to 90 minutes, depending on the time of day. A single ride fare costs $2.00, and a day pass is available for $4.00. Exact change is required. The buses are equipped with wheelchair lifts to accommodate passengers with mobility devices. There are no designated bus shelters at the stop near the post office, so waiting passengers may be exposed to the elements, including sun and rain. It’s advisable to check the Monroe County Transit website or app for the most up-to-date schedule and route information. While taxis and ride-sharing services like Uber and Lyft are available in Marathon, they can be more expensive than the bus, especially during peak tourist season. The bus stop at 52nd Street is located on the east side of Overseas Highway, requiring passengers traveling from the south to cross the highway at the crosswalk.
