Collier County contains 21 deliverable postal ZIP codes, covering roughly 815 square miles, or about one-third of the total county area. The remaining area consists of water bodies and undeveloped land, which the U.S. Postal Service classifies as undeliverable.

Naples Geo Codes

The NABOR Geo Codes refer to geographic codes established by the Naples Area Board of Realtors® (NABOR) to categorize and define specific areas within Collier and Lee Counties, Florida. These codes are used in the Multiple Listing Service (MLS) to help real estate professionals, buyers, and sellers accurately identify property locations based on predefined boundaries.

Each NABOR Geo Code corresponds to a particular neighborhood, community, or region within the Naples and Southwest Florida area. These codes simplify property searches, allowing users to filter listings by specific geographic areas rather than relying solely on ZIP codes or city names.

Key Features of NABOR Geo Codes:

  • Standardized Mapping: Ensures consistency in property location classification.
  • Efficient Property Searches: Helps buyers and agents find listings in their preferred areas.
  • Community-Based Organization: Many codes correspond to well-known communities and developments.
  • Market Insights: Used for tracking real estate trends and market reports
