303 Area Code Scam Report
Area Code 303
The 303 area code covers Area Code 303 and ranks #123 out of all U.S. area codes for scam call complaints. The FTC has logged 49,191 complaints from 27,852 unique phone numbers in the 303 prefix. The FCC independently recorded another 2,675 complaints, meaning people are reporting these numbers to multiple federal agencies.
But here is what makes 303 distinctive: 73.1% of victims are Colorado residents, and 65% of victims have a 303 number themselves. This is a textbook neighbor spoofing pattern. Scammers fake a 303 caller ID because people in the Colorado 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 303 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 303 because it is a large, recognizable Colorado area code. When your phone rings and shows a 303 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 303 numbers:
- 73.1% of victims are in Colorado, confirming local targeting
- 65% of victims have a 303 number themselves, meaning scammers match the victim's own area code
- The remaining 27% of complaints come from all 50 states, showing these numbers also appear in broader campaigns
What 303 Scam Calls Are About
Not all 303 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 84.3%, meaning 8 out of 10 calls are robots. Reducing your debt (credit cards, mortgage, student loans) follows at 73.4%. If your phone rings from a 303 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 303 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 303 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.

Fort Worth's 817 has the highest in-state targeting rate at 84%, while 469 sits at 73.1%. This suggests 817 is used almost exclusively for neighbor spoofing, while 469 sees slightly more use in broader nationwide campaigns.
