Jupiter Florida ZIP Codes & Maps

Jupiter, Florida, is served by five primary ZIP codes: 33458, 33477, 33478, 33469, and 33410 (partially). This article explains which areas each code covers, how to look up an exact address, and what to know about mailing, property lines, and hurricane evacuation zones.

Formula

There is no mathematical formula for a ZIP code. A ZIP code is a geographic routing label assigned by the U.S. Postal Service (USPS). The first digit (3) covers a multi-state region, the next two digits (34) narrow it to a sectional center facility, and the last two digits identify a specific post office or delivery area. Jupiter’s codes all begin with 334.

Worked Example

Using the default values from the calculator above: if you run 10 km in 50 minutes, your average pace is 50 ÷ 10 = 5.00 min/km, and your average speed is 10 ÷ (50/60) = 12.00 km/h. The calculator block demonstrates the speed/pace conversion, but it is unrelated to ZIP codes—it is here to show how the calculator works.

Background: How Jupiter’s ZIP Codes Were Assigned

Jupiter is a coastal town in Palm Beach County, about 20 miles north of West Palm Beach. The USPS assigns ZIP codes based on delivery logistics, not city boundaries. That is why some codes cover unincorporated areas, and why a small part of Jupiter falls under a neighboring city’s code. The 334 prefix is shared by many Palm Beach County communities, so the last two digits are what distinguish Jupiter from, say, Palm Beach Gardens (33410, 33418) or North Palm Beach (33408).

The Five Main Jupiter ZIP Codes

• 33458 – The largest and most central code. Covers downtown Jupiter, Jupiter Inlet Colony, and most of the mainland west of US-1. Includes Jupiter High School, Jupiter Medical Center, and the Jupiter Town Hall area.
• 33477 – Covers Jupiter Island (the barrier island) and the eastern part of the town, including the Jupiter Beach area and the Jupiter Inlet Lighthouse. This is the most exclusive and hurricane-exposed zone.
• 33478 – Covers the western and northwestern parts of Jupiter, including communities like Jupiter Farms and Limestone Creek. This is a more rural, equestrian-oriented area with larger lots.
• 33469 – Covers the northern coastal area, including Tequesta and Jonathan Dickinson State Park. Technically, Tequesta is a separate village, but its ZIP code is often used for Jupiter mailing addresses.
• 33410 – Partially covers the southern edge of Jupiter, especially the area around Donald Ross Road and the Intracoastal Waterway. This code is shared with Palm Beach Gardens and North Palm Beach.

How to Look Up an Exact Address

If you need the precise ZIP code for a street address, use the USPS ZIP Code Lookup tool on their official website. Enter the street number, street name, city, and state, and it will return the correct ZIP+4. The +4 extension identifies a specific block or building, which is useful for bulk mailers or property records. For a property’s legal description, check the Palm Beach County Property Appraiser’s website, which lists the ZIP code for every parcel.

Common Problems and Misconceptions

One common mistake is assuming that a Jupiter mailing address means the property is within Jupiter city limits. Many addresses in 33458 or 33478 are in unincorporated Palm Beach County, which means they pay county taxes and follow county zoning rules, not town ordinances. Another misconception is that ZIP codes determine hurricane evacuation zones—they do not. Evacuation zones are based on storm surge risk and are assigned by the county, not by ZIP. Always check the Palm Beach County evacuation zone map before a storm.

How to Choose a ZIP Code for Mailing or Moving

When choosing a home or a mailing address, consider these factors:

• Flood risk: 33477 (barrier island) has the highest flood risk; 33478 (western) has the lowest.
• School zones: 33458 and 33477 feed into Jupiter schools; 33478 may feed into different schools.
• Homeowners insurance: Premiums vary by flood zone, not ZIP, but ZIP can be a rough proxy.
• Delivery times: All Jupiter ZIP codes get similar USPS service, but 33477 may have limited mail delivery due to island access.

Safety and Emergency Planning

Jupiter is prone to hurricanes, and the barrier island (33477) is often ordered to evacuate first. The town’s emergency management office publishes a map showing evacuation zones A, B, C, and D. Zone A is the most vulnerable. Even if you live in 33458, you may be in Zone B or C. Keep a hurricane kit with water, non-perishable food, medications, and important documents. Also, note that 33478 has a higher wildfire risk due to rural vegetation.

Frequently Asked Questions

What is the ZIP code for Jupiter, FL?

The primary ZIP code is 33458, but the town also uses 33477, 33478, 33469, and 33410. The correct one depends on the specific street address.

Are Jupiter and Jupiter Island the same ZIP code?

No. Jupiter Island (the barrier island) is in 33477, while the mainland town is mostly in 33458. The island is a separate municipality, but it shares the Jupiter name.

Does 33410 cover Jupiter or Palm Beach Gardens?

Both. The 33410 ZIP code straddles the boundary between Jupiter and Palm Beach Gardens, especially near Donald Ross Road. Always verify with a full address.

Why does my mailing address say Jupiter but my property taxes go to the county?

Because the USPS assigns ZIP codes for mail delivery, not for government jurisdiction. Many areas with a Jupiter mailing address are in unincorporated Palm Beach County and are governed by the county, not the town of Jupiter.

How do I find the ZIP+4 for my address?

Use the USPS ZIP Code Lookup tool on the official USPS website. Enter your full street address, and it will give you the complete ZIP+4 code.

What is the best ZIP code to live in Jupiter?

There is no single “best” code—it depends on your priorities. 33477 offers beach access but higher flood risk and cost; 33478 offers larger lots and a rural feel; 33458 offers convenience and schools. Visit the areas to decide.
