Geographic Regions and Area Codes

The newly introduced 645 area code serves specific regions in South Florida, primarily Miami-Dade County and the Florida Keys. This area code is an overlay, meaning it covers the same geographic areas currently served by the 305 area code and the 786 area code. This overlay ensures that businesses and residents in these regions have access to new phone numbers without changing their existing numbers.

Key regions covered by the 645 area code include:

  • Miami-Dade County
  • The Florida Keys

For businesses, understanding the area codes in their region is crucial for effective communication and customer service. The introduction of the 645 area code provides additional opportunities for businesses to secure new phone numbers as the demand continues to grow.
