Frequently Asked Questions about the 305 Area Code
Who called me from a 305 number?
A 305 number is assigned to Miami, Florida, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 305 code to look nearby, so a 305 number doesn't prove the caller is local. Recently, 798 unwanted-call complaints were reported to the FTC for numbers showing the 305 code (66% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 305 a scam area code?
No area code is a scam on its own. 305 is a normal, officially assigned code for Miami, Florida. Spam callers spoof local codes to raise the odds you answer, so 305 on your caller ID says nothing about who is really calling. Recently, 798 unwanted-call complaints were reported to the FTC for numbers showing the 305 code (66% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 305 area code?
Repeated calls from different 305 numbers are usually spoofing: a robocaller rotates through 305 numbers so each call looks local and slips past simple blocks. Recently, 798 unwanted-call complaints were reported to the FTC for numbers showing the 305 code (66% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.
Should I answer an unknown 305 number?
If you aren't expecting a 305 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.
How do I block calls from the 305 area code?
Block a single 305 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 305 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 305?
Area code 305 covers Miami and the surrounding area in Florida, spanning 86 cities with about 2,718,784 residents. It shares its area with overlay codes 645, 786.

What timezone is the 305 area code in?
The 305 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 305 caller may not be in that zone.
How do I call a 305 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 305 and the seven-digit number. From a mobile phone you can usually just enter +1 305 followed by the number and let the phone add the exit code for you.
