Key Findings
Area code 314 (St. Louis, Missouri) ranks #44 nationally with 47,561 FTC complaints from 18,734 unique scam numbers. ScamVerify™ analysis reveals a dual-threat profile: medical scams lead at 4,818 complaints while debt reduction at 4,601 has an 82.4% robocall rate, placing 314 in both the medical targeting and automated debt campaign categories simultaneously.
St. Louis is the only major city in our series where AI voice cloning has been documented as a specific local threat. A St. Louis County man was targeted by a scammer who cloned his daughter's voice to demand emergency money (KSDK). St. Louis Police are considering tracking AI-driven scams as a separate crime category. The 314-880-7 scam ring prefix averages an extraordinary 56.7 complaints per number, the highest concentration found in any deep-dive area code. In March 2026, fake traffic violation texts with QR codes mimicking St. Louis County Court documents flooded the area. Missouri's HB 564, if passed, would make the state one of the first allowing private citizens to sue over caller ID spoofing.
314 in the Missouri Context
St. Louis dominates Missouri's scam landscape with the 557 overlay added in August 2022.
| Area Code | Region | Complaints | Nat'l Rank | In-State % |
|---|---|---|---|---|
| 314 | St. Louis city / inner ring | 47,561 | #44 | 59.3% |
| 816 | Kansas City | 31,196 | #154 | 67.9% |
| 636 | West St. Louis suburbs | 18,274 | #245 | 63.6% |
| 417 | Springfield | 21,701 | #216 | 67.6% |
| 573 | Jefferson City | 21,146 | #221 | 60.9% |
| 660 | Northern MO | 9,350 | #309 | 58.6% |
The St. Louis metro (314 + 636) generates 65,835 combined complaints, 44.1% of the state total. For full Missouri state context, see ScamVerify's Missouri Phone Scam Report.
The Dual-Threat Profile
Area code 314 is unusual in having two near-equal top categories with very different automation levels.
| Rank | Scam Category | Complaints | Robocall % |
|---|---|---|---|
| 1 | Medical and prescriptions | 4,818 | 53.0% |
| 2 | Debt reduction | 4,601 | 82.4% |
| 3 | Government/business impersonation | 3,608 | 63.1% |
| 4 | Home improvement and cleaning | 716 | 26.7% |
| 5 | Warranties and protection plans | 572 | 55.6% |
| 6 | Vacation and timeshares | 391 | 21.7% |
| 7 | Energy, solar, and utilities | 385 | 60.8% |
| 8 | Charities | 343 | 52.2% |
Medical (4,818) and debt (4,601) are separated by just 217 complaints. But their automation profiles are sharply different: debt runs at 82.4% robocall (automated campaigns) while medical runs at 53.0% (nearly half live-operator). This suggests two distinct scam ecosystems operating through 314 numbers.
Home improvement ranks #4 with 716 complaints at just 26.7% robocall rate, meaning nearly three-quarters use live operators. The 206 Seattle area code has a similar elevated home improvement profile (1,146 complaints at 20.8% robocall rate), driven by expensive housing markets attracting renovation fraud. Vacation and timeshares at 391 (21.7% robocall) are elevated for a non-tourism city.
AI Voice Cloning: The St. Louis Threat
St. Louis is at the forefront of a new scam technology. KSDK reported that a St. Louis County man was called by someone who sounded exactly like his daughter, claiming she needed emergency money. The voice was an AI-generated clone built from publicly available audio, likely social media videos.
- St. Louis Police Department is considering tracking AI-driven scams as a separate crime category
- UMSL cybersecurity program director Abde Mtibaa is studying the pattern
- The FBI warns scammers need only 3-5 seconds of audio to create a convincing voice clone
- St. Louis families are advised to establish a secret code word that only family members know
This represents an evolution beyond traditional phone scams. A spoofed caller ID showing a 314 number combined with an AI-cloned familiar voice bypasses both technical screening and human judgment simultaneously.
The 314-880-7 Scam Ring
ScamVerify identified 10 organized number blocks within 314, led by an unusually concentrated operation.
| Block | Numbers | Complaints | Avg/Number |
|---|---|---|---|
| 314-880-7xxx | 6 | 340 | 56.7 |
| 314-408-1xxx | 28 | 259 | 9.3 |
| 314-794-0xxx | 14 | 217 | 15.5 |
| 314-834-9xxx | 16 | 169 | 10.6 |
| 314-936-9xxx | 17 | 159 | 9.4 |
| 314-542-8xxx | 15 | 132 | 8.8 |
The 314-880-7 block has just 6 numbers averaging 56.7 complaints each, over 22 times the national average. This is the most concentrated scam ring per number of any area code in our entire deep-dive series. The lead number (314) 880-7703 has 181 complaints with 94 (51.9%) for medical scams. Its neighbor (314) 880-7718 has 66 complaints with 12 medical.
The 314-408-1 block is the largest by number count: 28 sequential scam numbers generating 259 complaints, indicating an industrial-scale VoIP operation. Adjacent prefix 314-794-0 has 14 numbers, and block 314-936-9 has 17 numbers. Combined, these 10 blocks contain 123 sequential scam numbers generating 1,781 complaints.
The 557 Overlay Confusion
Area code 557 was added to the St. Louis metro in August 2022 as an overlay of 314. Both codes serve the exact same geographic area. The overlay introduces confusion that scammers exploit:
- New numbers provisioned with 557 are unfamiliar to residents, making them look "suspicious" when legitimate and "local" when spoofed
- Scammers can alternate between 314 and 557 numbers for the same campaign
- Residents may not recognize 557 as a local St. Louis code
Top 10 Most Reported 314 Phone Numbers
| Rank | Phone Number | Complaints | Primary Category |

| 4 | (314) 888-6257 | 125 | Impersonation (45, 36%), mixed |
| 5 | (314) 470-4753 | 115 | Robocaller (92%), dropped calls |
| 6 | (314) 794-0942 | 102 | Charities (6), mixed |

The Traffic Court QR Code Scam
In March 2026, fake traffic violation texts flooded the St. Louis area with fraudulent "Notice of Hearing - Toll Violation" messages. The texts included:
- A fabricated court document with a fake St. Louis County Court seal
- A fictional clerk named "John Smith"
- A QR code leading to a payment portal that harvested financial information
The 16th Judicial Circuit issued a press release confirming the scam. Missouri courts never collect fines by text or QR code. This campaign targeted multiple Missouri cities simultaneously, including Kansas City.
314 vs. Other Top Area Codes
| Area Code | Location | Complaints | Per # | In-State % | #1 Category |
|---|---|---|---|---|---|
| 502 | Louisville KY | 56,834 | 2.5 | 46.7% | Debt (89.0%) |
| 314 | St. Louis MO | 47,561 | 2.5 | 59.3% | Medical (53.0%) |
| 816 | Kansas City MO | 31,196 | 2.4 | 67.9% | Medical (74.6%) |
| 313 | Detroit MI | 38,925 | 3.1 | 56.2% | Debt (87.4%) |
St. Louis's 59.3% in-state targeting places it between the nationwide campaign codes (502, 313) and local targeting codes (816). Its dual-threat profile (medical + debt) is rare: most area codes are dominated by one category or the other. The 314-880-7 ring's 56.7 per-number average exceeds the highest concentration in 313 Detroit (29.0 per number in the 313-380-9 block).
What to Do If You Get a Scam Call From a 314 Number
- Check any 314 number on ScamVerify's phone lookup before calling back. We have 18,734 known scam numbers in the 314 area code.
- Report the call to the FTC at ReportFraud.ftc.gov and to the MO AG at 800-392-8222.
- Establish a family code word. The AI voice cloning threat in St. Louis means a familiar voice is no longer proof of identity. If a "family member" calls requesting emergency money, hang up and call them directly on their known number.
- Ameren never calls about solar panels. If someone claims to represent Ameren offering solar installation, it is a scam. Call Ameren at 1-800-552-7583.
- Missouri courts never collect fines by QR code. If you receive a text about a traffic violation with a payment link, delete it.
