Is Area Code 667 a Scam?
It’s added to the 443 region in 2012 and serves Baltimore and surrounding communities. But legitimacy of the code says nothing about any single call. Scammers spoof local numbers constantly.
Been targeted? Report it to the FTC at reportfraud.ftc.gov. Reports feed the complaint data that powers spam blocking.
Scam texts from area code 667 numbers
The most common area code 667 text scam is the “wrong number” opener: a friendly message that pretends to know you, then moves the chat to WhatsApp and eventually to an investment pitch. Scripts currently circulating:
- “U at home?” · “Are you busy tomorrow?” · “How are you doing?”
- Delivery-problem and job-offer texts that link out to a login page
Don’t reply. A response marks your number as live. Forward scam texts to 7726 (SPAM), and AT&T ActiveArmor® filters known senders automatically.
How number spoofing works in area code 667
Caller ID is easy to forge. Spoofing fakes the number a call displays. The real owner of that 667 number isn’t involved and usually has no idea. That’s why blocking one number rarely stops the calls.
- A call from a number almost identical to yours (same 667 and prefix) is “mirror spoofing.” A missed call from your own number is never worth returning.
- Strangers calling you back saying you called them? Your 667 number is being spoofed. It typically passes within days, and you don’t need a new number. Report it at reportfraud.ftc.gov.
- The caller-ID checkmark: AT&T verifies network calls (STIR/SHAKEN). A verified mark means the displayed number wasn’t faked. No mark doesn’t always mean scam, but treat it with more caution.
Spoofed or not, the rule holds: unexpected caller, no voicemail? Let it go.
667 Area Code Prefix & Carrier Lookup
The three digits after the area code identify the carrier a number was issued to. All 446 assigned 667 prefixes below are real, from the public numbering registry. Type to filter.
This isn’t a reverse phone lookup: no legitimate free service can tell you who owns a specific number. What a 667 prefix does show: the carrier that issued it, whether it’s wireless, landline or VoIP, and the community it belongs to, which is often enough to judge whether a call was worth returning.

Area Code 667: More Than a Number in Baltimore
In Baltimore, the 667 is more than digits on a caller ID. It arrived in 2012, layered onto the 443 region, and it has meant Baltimore and surrounding communities ever since — 446 carrier prefixes keep its lines busy today, and an established 667 number still says you’ve been here a while.
The map tells its own story: Baltimore and surrounding communities, with 410 and 443 sharing the same streets today. Several codes, one local calling area, no long-distance between any of them — only the 667 came first.
Keeping a 667 matters here. An existing 667 number ports to a new phone, a new carrier, or a new AT&T line, and stays yours anywhere in the U.S. New lines in the area often draw 410 instead — one more reason locals hold on to theirs.
