About the 305 region
305 covers Miami in Florida, including Hialeah, Coral Gables and Key West. The code has been in service since 1947 and is one of the original North American area codes.
As the Miami region grew, 305 ran low on available numbers, so 786 was added as an overlay code over the same geographic area. Both codes are local to each other and 10-digit dialing applies throughout.

Who called me from 305?

- Avoid calling back unknown one-ring numbers — some premium-rate scams rely on curiosity callbacks.
- Never share verification codes, payment details, or remote access during an unsolicited call, even if the caller claims to be your bank or a government agency.
- When a 305 call pressures you to act immediately, hang up and contact the organization directly through its official number.
