Why doesn't a Boca Raton ZIP code settle the question?
The City of Boca Raton states that having a Boca Raton address does not necessarily mean you live within City limits. ZIP codes were never designed to follow city boundaries.
According to the US Census Bureau, the ZIP Code is a US Postal Service trademark created to coordinate mail handling and delivery, and ZIP Codes are assigned to delivery routes. To map them, the Census Bureau builds ZIP Code Tabulation Areas (ZCTAs), which are generalized areas built from 2020 census blocks, so a ZCTA approximates a ZIP code rather than matching it exactly.[1][2]
How do the main Boca Raton ZIP codes split?
The Census Bureau's 2020 ZCTA-to-Place Relationship File reports how much of each ZCTA's land area falls inside each incorporated city. For the residential ZIP codes commonly used for Boca Raton addresses, the share of land area inside the City of Boca Raton (2020 boundaries) is:
- 33431: 100% inside the city
- 33432: 100% inside the city
- 33486: 100% inside the city
- 33487: about 71% inside the city, about 8% in the Town of Highland Beach, and the rest outside any city or town
- 33496: about 35% inside the city
- 33434: about 20% inside the city
- 33433: about 11% inside the city
- 33428: no land inside the city
- 33498: no land inside the city[3]
How do I confirm a specific property?
Percentages describe land area, not individual homes, and they reflect 2020 boundaries. For a specific address, use the City's Boca Raton Residency Map, which shows whether a home is a City of Boca Raton residence (blue), a Greater Boca Raton Beach and Park District residence (yellow), or a Palm Beach County residence (green).
The City's beach permit page makes the same point: parts of Boca Raton are in the Greater Boca Raton Beach and Park District and some are in unincorporated Palm Beach County. Check the exact address before assuming which taxes, permits or services apply.[1][4]
Key takeaways
