Finding the right postal designation on the Big Island can get confusing fast, especially since Kailua-Kona covers multiple zones and nearby coastal communities rely on entirely different numbers. The primary Kona Hawaii zip code for the main town center and residential areas is 96740, while post office boxes use 96745. If you're shipping gear, booking a rental, or looking up addresses along the western coast, getting these numbers right matters.
Beyond the town center, the broader Kona district spans several distinct postal zones from North Kona down through South Kona. Knowing these specific boundaries keeps your mail from getting delayed and helps you navigate the region accurately.
Core Kona Town Postal Codes
The urban and commercial center of Kailua-Kona splits its postal routing into standard delivery routes and designated box numbers.
- 96740: This is the primary standard delivery code covering most residential neighborhoods, businesses, and resorts stretching along the immediate coast and up the lower slopes of Hualalai.
- 96745: This code is dedicated strictly to Post Office Box (PO Box) deliveries located at the main Kailua-Kona post office.
If you are shipping physical packages via couriers like FedEx or UPS, they deliver directly to physical street addresses using 96740. USPS mail sent to a PO Box requires 96745. Mixing these up frequently causes delivery exceptions.
Surrounding Kona District Zip Codes
The "Kona" region isn't just a single town; it encompasses a massive coastal and mountain strip. Depending on where you are heading along the Hawaii Belt Road (Route 19 or Route 11), the postal numbers change entirely.
North Kona and Coastal Suburbs
- 96725: Covers areas just north and inland, including Holualoa and portions of Kalaoa. Coffee farms tucked into the slopes often use this designation.
- 96738: Assigned to the Waikoloa resort and village area just north of the Kona airport corridor.
South Kona Communities
- 96750: Primarily serves Kealakekua, home to the regional hospital and historical Captain Cook areas just south of Kona town.
- 96739: Designated for Keauhou, covering the bay, shopping center, and resort properties immediately south of Kailua-Kona.
- 96704: Used for Captain Cook and Honaunau (near Pu'uhonua o Honaunau National Historical Park).

Common Shipping and Mailing Mistakes to Avoid
Mailing items to the Big Island comes with unique logistical hurdles. Avoid these frequent errors:
- Confusing Hilo and Kona: Hilo (on the east side) uses 96720. Mail sent with a Kona address but a Hilo zip code routinely spends extra weeks in transit sorting facilities.
- Omitting the Island Name: Always include "Hawaii" or "HI" alongside the zip code. Automated sorting machines occasionally misroute ambiguous state abbreviations.
- Assuming Street Delivery Works Everywhere: Many rural properties in South Kona do not receive home mail delivery from USPS. Residents rely entirely on local PO boxes, making 96745 or nearby station boxes essential.
