Spam calls from area code 516? Here's how to stop them.
Area code 516 covers Hempstead, NY — 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 516 calls, here's the truth: it's almost certainly not someone in Hempstead, NY. It's a robocaller spoofing a Nassau County number so the call looks local and you pick up. You hang up, they dial the next 516 number. You're one row in a spreadsheet.
Don't block 516 — screen it. Real calls come from 516 too. Known callers should ring through; unknown 516 numbers should hit a wall first.
What 516 actually is
Across a sample of 18,440 recent FTC reports (through 2026-07-23), consumers logged 109 complaints about calls that displayed a 516 number. Because caller ID is spoofed, almost none actually originated in Hempstead — the number is a costume, and this is how often it gets worn against people who share it.
516 is an original-era code. Its middle digit (1) dates it to the 1947–1995 numbering plan, when the middle digit could only be 0 or 1. Codes this old cover long-settled, densely-dialed territory — which is exactly why spoofers love wearing them: a 516 number reads as established and trustworthy.
516 is one of 17 area codes serving New York — the others are 212, 315, 332, 347, 518, 585, 607, 631, 646, 716, 718, 845, 914, 917, 929 and 934 — and 516 specifically covers Nassau County. 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 516 belong to the Eastern time zone. A "local" 516 call that rings at 3 a.m. almost always originated in a boiler room several zones away, dialing your daytime from their own.
Why 516 keeps calling you
Spoofing engines pull the first six digits of your number and dial matching 516 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?
