No, 645 is a new Miami area code that entered service in 2023 as an overlay to the existing 305 and 786 prefixes. Its very recent introduction means many residents may not yet recognize it as a genuine local number, creating confusion that spoofing campaigns can exploit.
Miami's established fraud patterns across its overlapping codes suggest 645 will be used for the same high-volume campaigns already documented in 305 and 786. The Miami area is particularly active for Medicare fraud given its large senior population, and government impersonation scams are consistently among the top complaints across South Florida's area codes.
Phone numbers with the 645 area code prefix originate from southern Florida, encompassing Miami, Miami-Dade County, and the Florida Keys area within Monroe County.
Area code 645 is part of an overlay system that serves the same geographic region as area codes 305 and 786 . Area code 305 was the original code for this region. Area code 786 was installed as an overlay on March 1, 1998, and area code 645 was activated on August 4, 2023, before the anticipated exhaustion of central office codes in 305 and 786. Within this overlay system, ten-digit dialing is required for calls.
Area code 645 is a general purpose code which was placed in service on August 4, 2023.
