Spam calls from area code 620? Here's how to stop them.
Area code 620 covers Dodge City, KS — but the spammers calling from it are faking the number. Here's why, and how to block it free.
If your phone keeps lighting up with area code 620 calls, here's the truth: it's almost certainly not someone in Dodge City, KS. It's a robocaller spoofing a southern Kansas number so the call looks local and you pick up. You hang up, they dial the next 620 number. You're one row in a spreadsheet.
Don't block 620 — screen it. Real calls come from 620 too. Known callers should ring through; unknown 620 numbers should hit a wall first.
What 620 actually is
Across a sample of 18,440 recent FTC reports (through 2026-07-23), consumers logged 12 complaints about calls that displayed a 620 number. Because caller ID is spoofed, almost none actually originated in Dodge City — the number is a costume, and this is how often it gets worn against people who share it.
620 is a newer code. Its middle digit (2) was impossible before 1995 — back then the middle digit was locked to 0 or 1. When those ran out, the plan opened up 2–9, and codes like 620 were minted, almost always as overlays stacked on an older code in the same place. Newer overlay codes are prime spoofing material because they still look local but nobody has them memorized.
620 is one of 4 area codes serving Kansas — the others are 316, 785 and 913 — and 620 specifically covers southern Kansas. That geographic specificity is the whole point of the spoof: a scammer picks the code that looks closest to you.
One tell the spoof can't hide: time. Numbers on 620 belong to the Central time zone. A "local" 620 call that rings at 3 a.m. almost always originated in a boiler room several zones away, dialing your daytime from their own.
Why 620 keeps calling you
Spoofing engines pull the first six digits of your number and dial matching 620 numbers — the “neighbor” trick. A call sharing your area code and prefix feels safe, so answer rates jump. That's the whole scam: familiarity. Read the mechanics in neighbor spoofing, and why you got picked in why me?

Why am I getting spam calls from area code 620?
Because auto-dialers spoof it. They fake a 620 (Dodge City, KS) number so the call looks local and you answer. The caller is almost never actually in Dodge City — the number is a mask, and a newer overlay like 620 picks it precisely because it looks close to you. See neighbor spoofing.
Is a call from 620 always spam?
No. Real people and businesses in Dodge City use 620 too, so blanket-blocking it costs you real calls. Screen instead: known contacts ring through, unknown 620 numbers get checked first.
