559 Area Code Scam Report
Fresno, CA
Updated Jun 28, 2026 · FTC complaint data
The 559 area code covers Fresno, CA and ranks #126 out of all U.S. area codes for scam call complaints. The FTC has logged 49,044 complaints from 25,089 unique phone numbers in the 559 prefix. The FCC independently recorded another 1,369 complaints, meaning people are reporting these numbers to multiple federal agencies.
But here is what makes 559 distinctive: 73.7% of victims are California residents, and 46% of victims have a 559 number themselves. This is a textbook neighbor spoofing pattern. Scammers fake a 559 caller ID because people in the California area are far more likely to answer a call that looks like it is coming from their own neighborhood. The number on your screen is fabricated.

Why Scammers Spoof 559 Numbers
Caller ID spoofing is trivially easy with modern VoIP technology. Scammers operating from anywhere in the world can make your phone display any number they choose. They pick 559 because it is a large, recognizable California area code. When your phone rings and shows a 559 number, your instinct is that it might be a local business, a doctor's office, or someone you know. That instinct is exactly what scammers exploit.
The data confirms this. Of all FTC complaints about 559 numbers:
- 73.7% of victims are in California, confirming local targeting
- 46% of victims have a 559 number themselves, meaning scammers match the victim's own area code
- The remaining 26% of complaints come from all 50 states, showing these numbers also appear in broader campaigns
What 559 Scam Calls Are About
Not all 559 scam calls run the same playbook. The FTC categorizes complaints by subject, and the automation rate (robocall percentage) reveals which scams are run by machines versus live callers.
Warranties & protection plans scams have the highest automation rate at 90.8%, meaning 9 out of 10 calls are robots. Reducing your debt (credit cards, mortgage, student loans) follows at 76.6%. If your phone rings from a 559 number and you hear a recorded message about debt, tech support, or a government agency, it is almost certainly spoofed.

What to Do If You Get a Call from a 559 Number
If you did not answer
Do not call back. Scammers spoof real people's numbers, so calling back may reach an innocent person. Instead, check the number on ScamVerify™ to see if it has been reported. If there is no voicemail, it was almost certainly a robocall.
If you answered
Hang up immediately if you hear a recorded message. If a live person asks for personal information, payment, or claims to be from the IRS, Social Security, or your bank, do not engage. Legitimate agencies do not cold-call demanding immediate payment. Check the number below, then report it to the FTC at donotcall.gov.
Remember: the number is not real
The 559 number that appeared on your screen was almost certainly spoofed. The actual caller could be anywhere. This is why blocking individual numbers has limited value. Scammers generate thousands of spoofed numbers and discard them after a few calls.
