Who Called Me from Area Code 605?
Quick answerA 605 call usually comes from Sioux Falls or nearby communities, but caller ID can be spoofed, so a local-looking number isn’t proof. If there’s no voicemail, let it go: legitimate callers leave messages.

Is Area Code 605 a Scam?
No. 605 is a legitimate Sioux Falls area code.
It’s one of the original 1947 codes and serves Sioux Falls and surrounding communities. But legitimacy of the code says nothing about any single call. Scammers spoof local numbers constantly.
The code is realOriginal 1947 code for the Sioux Falls area with 744 assigned carrier prefixes.
Spoofing happens“Neighbor spoofing” fakes local numbers. No voicemail? Let it go.

Scam texts from area code 605 numbers
The most common area code 605 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 605
Caller ID is easy to forge. Spoofing fakes the number a call displays. The real owner of that 605 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 605 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 605 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.
605 Area Code Prefix & Carrier Lookup
The three digits after the area code identify the carrier a number was issued to. All 744 assigned 605 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 605 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.

The 605, explained
Area Code 605: More Than a Number in Sioux Falls
In Sioux Falls, the 605 is more than digits on a caller ID. It’s one of the original area codes of 1947, and it has meant Sioux Falls and surrounding communities ever since — 744 carrier prefixes keep its lines busy today, and an established 605 number still says you’ve been here a while.
The map tells its own story: Sioux Falls and surrounding communities, with no overlay on its territory. The area and the code are still one and the same — rare in South Dakota and getting rarer nationwide.
Keeping a 605 matters here. An existing 605 number ports to a new phone, a new carrier, or a new AT&T line, and stays yours anywhere in the U.S.
