The Central Islip Post Office at 110 EAST SUFFOLK AVENUE in Central Islip serves as a critical point of connection for residents and businesses across this dynamic Suffolk County community. Located on the northern side of East Suffolk Avenue, just west of its intersection with Lowell Avenue, this facility is strategically positioned to cater to a diverse demographic. Its immediate surroundings reflect the quintessential suburban Long Island landscape, characterized by a mix of single-family homes, established multi-family residences, and localized commercial strips that line major arteries. The post office itself is readily identifiable by its classic red-brick facade and prominent flagpole, a fixture in the neighborhood for decades.
This specific branch is frequently utilized by a broad spectrum of Central Islip’s population. Young families residing in the quiet residential pockets south of East Suffolk Avenue, between Carleton Avenue and Wheeler Road, often rely on this facility for both traditional postal services and, increasingly, for passport application assistance for their children. Professionals commuting via the nearby Central Islip LIRR station, approximately 0.8 miles to the west, find the location convenient for last-minute document drop-offs or scheduled passport appointments during their workdays. Furthermore, local small business owners operating along Islip Avenue or near the bustling commercial corridor of Carleton Avenue depend on its services for daily mail operations, with many also accessing passport processing for international travel needs related to their enterprises. Students from the Suffolk County Community College Michael J. Grant Campus, situated roughly 2.5 miles east, and Touro College Jacob D. Fuchsberg Law Center, about 1.5 miles north, also frequent the post office for various needs, including international study permits or passport renewals.
The Central Islip Post Office holds a specific significance within the neighborhood, positioned as it is within the town’s older, more established core. Historically, Central Islip began its transformation from agricultural land and the grounds of the former Central Islip State Hospital into a burgeoning residential community in the mid-20th century. Facilities like this post office were instrumental in solidifying the infrastructure of this growing suburb. While the grand institutional structures of the state hospital have largely given way to new developments, including residential complexes and athletic fields, the post office has maintained its presence, adapting to the changing needs of the community. It stands as a testament to the continuous evolution of Central Islip from its post-World War II expansion period through modern-day revitalization efforts.
Unique to this location is its consistent staffing, which residents often commend for efficiency, particularly during the typically busiest hours between 11:00 AM and 2:00 PM on weekdays. Unlike some larger, busier facilities, the Central Islip Post Office maintains a more intimate, community-oriented atmosphere, fostering a sense of familiarity among repeat visitors. The team here often processes an average of 95 passport applications weekly, a substantial volume that underscores its importance as a regional passport acceptance facility.
Several key landmarks and community points of interest are within a short walk of the post office, adding to its accessibility and local integration. Less than two blocks east, at the corner of East Suffolk Avenue and Carleton Avenue, lies the Central Islip Public Library, a key community resource often visited in conjunction with post office errands. Approximately four blocks north, on Carleton Avenue, is the Suffolk County Family Court, a significant government institution that draws many visitors to the immediate vicinity. Additionally, a localized retail plaza featuring a modest diner and a specialty grocery store is located just three blocks west on East Suffolk Avenue, offering convenient stops before or after a post office visit. This confluence of civic services, residential zones, and local commerce solidifies the Central Islip Post Office’s role not just as a passport acceptance agent, but as an enduring and practical cornerstone of daily life for countless Central Islip residents.

Located at CENTRAL ISLIP POST OFFICE at 110 EAST SUFFOLK AVENUE. Easy access from major highways.
Parking at the Central Islip Post Office at 110 East Suffolk Avenue is generally straightforward, though it requires specific knowledge of the immediate vicinity. The facility provides a dedicated, asphalt surface lot directly adjacent to its eastern side, offering approximately 25 marked spaces. This lot is free and typically offers reasonable availability, especially during off-peak morning hours before 10:00 AM and later in the afternoon after 3:00 PM. Access to this lot is via a single entrance/exit point from East Suffolk Avenue itself. For times when the main lot is full, which can occur during the lunch rush (12:00 PM – 1:30 PM) or on Saturdays, ample free street parking is available along East Suffolk Avenue. While most of East Suffolk Avenue directly in front of the post office is no-standing, spaces can often be found just one block west, nearer the intersection of East Suffolk Avenue and Lowell Avenue, or slightly further east, past the nearby commercial storefronts. These spots typically do not have time restrictions, making them suitable for passport appointments. Arriving about 15-20 minutes prior to your scheduled passport appointment is a wise strategy, allowing you sufficient time to secure a spot without feeling rushed. Seasonal conditions warrant consideration; during the summer months, the exposed asphalt lot can become quite hot, so plan accordingly if waiting in your vehicle. Conversely, in the winter, particularly after heavy snowfall common to Suffolk County, the lot may have reduced capacity due to snow piles, and street parking might be less readily cleared. Ice can also be a factor in the early mornings, so extra caution is advised when walking from your vehicle to the entrance.
The Central Islip Post Office is reasonably accessible via public transit, primarily through the Suffolk County Transit bus network and the Long Island Rail Road (LIRR). For those arriving by bus, several routes serve the immediate vicinity. Suffolk County Transit Bus Route S33, which runs along Carleton Avenue, has a stop at the intersection of Carleton Avenue and East Suffolk Avenue, placing riders approximately two blocks, or a 0.2-mile walk, east of the post office. From this stop, simply head west on East Suffolk Avenue, and the post office will be on your right. The S33 operates with a frequency of approximately every 30-45 minutes on weekdays and hourly on weekends. A single ride on Suffolk County Transit costs $2.25, with a $5.50 day pass option. Another option is the Suffolk County Transit Bus Route S45, connecting areas like Smithtown and Brentwood, which also makes stops along Carleton Avenue. Similarly, the Central Islip LIRR station, a crucial hub for commuters, is located roughly 0.8 miles west of the post office, at 100 Suffolk Avenue. From the LIRR station, a walk eastbound along Suffolk Avenue (which becomes East Suffolk Avenue) will lead directly to the post office. This walk takes approximately 15-18 minutes. LIRR trains on the Main Line offer frequent service, especially during peak commuter hours (every 15-20 minutes), with off-peak service generally every 30-60 minutes. Fares vary based on destination and peak/off-peak travel. Both Suffolk County Transit buses and the Central Islip LIRR station are equipped with wheelchair ramps and accessible features, ensuring broad accessibility for all commuters.

Entering through Central Islip Post Office’s main doors, which are situated centrally on the building’s north-facing facade directly onto East Suffolk Avenue, visitors step into a well-lit, functional lobby. The entrance itself is equipped with a gently sloped ramp immediately to the right of the main steps, ensuring easy access for individuals using wheelchairs or strollers. The interior space, while compact, is efficiently laid out with a long service counter spanning the entire rear wall. Immediately upon entering, the self-service kiosks for postage are to your right, and the traditional P.O. Box section occupies the left side of the lobby.
For passport services, direct your attention to the far right end of the service counter, typically identified as Window #3 or #4 by clear overhead signage. This is where the dedicated passport acceptance agents are stationed. There isn’t a formal check-in desk separate from the main counter; instead, visitors with appointments are encouraged to approach this designated window when called or when a staff member becomes available. The architectural style inside is utilitarian, featuring durable linoleum flooring and fluorescent lighting, typical of a mid-20th century public service building. While straightforward, the environment is kept clean and orderly.
Accessibility is well-considered throughout the main lobby area; there are no internal steps, making it navigable for all. Restrooms, clearly marked, are also wheelchair accessible. A typical passport appointment at this facility is designed for efficiency, usually lasting between 18-22 minutes, assuming all documents are correctly prepared. This duration allows ample time for the acceptance agent to meticulously review all application materials, administer the oath for the DS-11 form, process the necessary payments, and, if required, take official passport photos on-site at a dedicated station adjacent to the passport acceptance window.
