City population is shown in full. The share of each city inside 667 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.

Caller ID is easily spoofed, so these figures reflect the number shown on caller ID, not the caller's true location – an area code alone never identifies a caller. The FTC does not verify the facts in these complaints. Source: FTC Do Not Call (DNC) Reported Calls Data, retrieved 2026-08-17.

Frequently Asked Questions about the 667 Area Code
Who called me from a 667 number?
A 667 number is assigned to Baltimore, Maryland, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 667 code to look nearby, so a 667 number doesn't prove the caller is local. Recently, 1,003 unwanted-call complaints were reported to the FTC for numbers showing the 667 code (72% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 667 a scam area code?
No area code is a scam on its own. 667 is a normal, officially assigned code for Baltimore, Maryland. Spam callers spoof local codes to raise the odds you answer, so 667 on your caller ID says nothing about who is really calling. Recently, 1,003 unwanted-call complaints were reported to the FTC for numbers showing the 667 code (72% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 667 area code?
Repeated calls from different 667 numbers are usually spoofing: a robocaller rotates through 667 numbers so each call looks local and slips past simple blocks. Recently, 1,003 unwanted-call complaints were reported to the FTC for numbers showing the 667 code (72% 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 667 number?
If you aren't expecting a 667 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 667 area code?
Block a single 667 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 667 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 667?
Area code 667 covers Baltimore and the surrounding area in Maryland, spanning 208 cities with about 3,212,271 residents. It shares its area with overlay codes 410, 443.
When did area code 667 go into service?
Area code 667 went into service on March 24, 2012. It was added as an overlay of 443, so 667 numbers serve the same area that 443 already covered.
Is 667 a real area code?
Yes. 667 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Baltimore, Maryland. A real code can still show up on spoofed spam calls, so treat unknown 667 calls with normal caution.
What timezone is the 667 area code in?
The 667 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 667 caller may not be in that zone.
How do I call a 667 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 667 and the seven-digit number. From a mobile phone you can usually just enter +1 667 followed by the number and let the phone add the exit code for you.
