Saint Marks (ZIP 32355) operates as a PO Box-only ZIP code serving 284 residents in Wakulla County, Florida. The post office maintains 218 PO Boxes for 155 households, giving it an adoption rate of 1.41. That's higher than the local household count, meaning people from surrounding areas also use this post office. This isn't uncommon for small coastal Florida communities where the post office serves as a regional mail hub.
The community skews older, with a median age of 54.7 years. About 88% of the population is white, and median household income sits at $57,083. The 199 total housing units include 155 occupied homes and 34 seasonal or vacation properties. Home values run higher than you might expect for such a small place, with a median of $270,800. The ZIP covers just 0.13 square miles along Florida's Gulf Coast.
Street delivery exists but it's minimal. The postal service maintains one city carrier route, one rural route, and one general delivery route. Port Leon Drive has the most delivery points with four records, while Parnewood Drive shows just one. Two named buildings appear in postal records: the Postmaster office and the Supervisor Accountable Paper facility. This delivery mix—mostly PO Boxes with limited street routes—fits the pattern for older coastal communities where residents prefer the security and convenience of post office boxes.
Port Leon Drive references the historic Port Leon settlement that was destroyed by a hurricane in 1843. The minimal street network—just two streets in postal records—reflects the tiny geographic footprint and heavy reliance on PO Box delivery. This isn't a traditional street-grid community but rather a small coastal settlement where most mail goes to post office boxes.
ZIP Code 32355 has 284 residents and 155 households (average 1.83 persons per household).

The gender split is 51.1% male and 48.9% female, which is slightly higher than the state male share (48.6%), making this a male-majority area. Largest groups are White (88.0%, much higher than the state average of 57.7% and well above the national average of 61.6%) and Hispanic or Latino (2.5%); Hispanic or Latino residents make up 2.5%, which is much lower than the state average (26.5%).
