Question 1

Do I need to dial the area code for local calls in 305?

Accepted Answer

Yes, ten-digit dialing (area code + seven-digit number) is required for all local calls in the 305/786/645 overlay region. This has been mandatory since 1998 when the 786 overlay was introduced. You must dial all ten digits even when calling another number with the same area code.

Scammers use a technique called 'neighbor spoofing' to display fake 305 area code numbers on caller ID, making calls appear to come from local Miami numbers.

Question 3

Can I get a 305 number if I don't live in Miami?

Accepted Answer

This is ideal for businesses wanting a Miami presence without a physical office in the area.
