An Island Apart

Sapelo Island sits off Georgia's coast, accessible only by ferry from Meridian. This barrier island spans nearly 55 square miles but is home to just 128 year-round residents. Most housing sits empty for much of the year. Of the island's 164 total housing units, 98 are seasonal (60%), creating dramatic population swings between summer and winter.

Why PO Boxes Are Essential

Mail delivery on Sapelo Island works differently than on the mainland. This is a PO Box Only Zone. There's no alternative mail delivery across the entire island. The post office maintains 32 PO Boxes for 46 occupied households, a 70% adoption rate that reflects both the small year-round community and seasonal property owners who maintain boxes to receive mail during their stays.

Island Geography and Street Names

Rural carrier route R001 serves the island's 45 named streets, from E Perimeter Rd (22 delivery points) to coastal roads like Shell Hammock Rd, Marsh Landing Rd, and Lighthouse Rd. Street names capture the island's character: Old Beach Rd, Nanny Goat Rd, Turkey Fountain Way, and Enchanted Forest Rd. Historic settlement patterns persist. 76 housing units predate 1939, and another 36 are mobile homes, creating a mix of old island homes and newer seasonal structures.

A Small, Diverse Community

Sapelo Island's year-round population is small but diverse. Of 128 residents, 58 are White (45%), 46 are Black (36%), and 16 identify as two or more races (12%). The Hispanic population is 26 (20%). Median age is 36.5 years. With just 5 children under 18 and 4 residents over 65, this isn't a typical family community or retirement destination. The island supports one business delivery point but no registered establishments, reflecting its primarily residential and conservation character.

Island Isolation and Mail Access

The island's isolation shapes daily life. No bridge connects Sapelo to the mainland. Residents depend on ferry service, making the post office a critical access point for mail, packages, and prescriptions. General delivery (route G001) is available for those without permanent addresses. The nearest mainland neighborhoods are Drum Point, Half Moon, and Cedar Point, all 15 to 17 miles away across the water.
