Spam calls from area code 575? Here's how to stop them.
Area code 575 covers Las Cruces, NM — 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 575 calls, here's the truth: it's almost certainly not someone in Las Cruces, NM. It's a robocaller spoofing a southern New Mexico number so the call looks local and you pick up. You hang up, they dial the next 575 number. You're one row in a spreadsheet.
Don't block 575 — screen it. Real calls come from 575 too. Known callers should ring through; unknown 575 numbers should hit a wall first.
What 575 actually is
Across a sample of 18,440 recent FTC reports (through 2026-07-23), consumers logged 32 complaints about calls that displayed a 575 number. Because caller ID is spoofed, almost none actually originated in Las Cruces — the number is a costume, and this is how often it gets worn against people who share it.
575 is a newer code. Its middle digit (7) 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 575 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.
575 is one of 2 area codes serving New Mexico — the others are 505 — and 575 specifically covers southern New Mexico. 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 575 belong to the Mountain time zone. A "local" 575 call that rings at 3 a.m. almost always originated in a boiler room several zones away, dialing your daytime from their own.
Why 575 keeps calling you
Spoofing engines pull the first six digits of your number and dial matching 575 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 575?
Because auto-dialers spoof it. They fake a 575 (Las Cruces, NM) number so the call looks local and you answer. The caller is almost never actually in Las Cruces — the number is a mask, and a newer overlay like 575 picks it precisely because it looks close to you. See neighbor spoofing.
Is a call from 575 always spam?
No. Real people and businesses in Las Cruces use 575 too, so blanket-blocking it costs you real calls. Screen instead: known contacts ring through, unknown 575 numbers get checked first.
