| Common Labels | Robocaller, SSA impersonator, fake civil lawsuit filer, fake PCH prize caller, IRS threat |
| Spoofing Risk | Scammers fake their caller ID to display local or familiar 903 numbers — if you live in or near Texas (Tyler, Longview, Sherman), scammers know you are more likely to answer what appears to be a local East Texas call |
| Typical Strategy | Neighbor spoofing — appearing as a familiar Tyler, Longview, or Sherman number to build trust before making fraudulent requests |
| Signature Scam — SSA Legal Enforcement Threat | Automated calls targeting East Texas residents claim "a legal enforcement action has been filed on your Social Security Number for fraudulent activity" such as money laundering or drug trafficking, threatening to block your SSN and begin state court proceedings unless you press 1 immediately — using your fear of losing benefits to extract personal information |
| Signature Scam — "Karen Haynes" Fake Civil Suit | The 903 and 430 area codes are specifically targeted by the "Karen Haynes" fake civil suit scam and "Complaint Filed Against You" threats, where callers impersonate legal officials claiming a complaint has been filed in your name and demanding immediate settlement to avoid court |
| Signature Scam — Fake PCH Prize | Callers claim you have won a large PCH (Publisher's Clearing House) prize and leave a callback number — once you call back, they demand fees or taxes be paid before the prize can be released, keeping your money while the non-existent prize is never delivered |
| Signature Scam — Fake SSA Banking Verification | A woman calling from a VoIP number pretends to be from the "Social Security Office in Longview, TX" and calls to "verify your banking and direct deposit information," impersonating an SSA employee to extract financial account details |
| Signature Scam — Fake Police/Firefighter Charity | The 903 region is also targeted by police and firefighter donation scams, with robocallers soliciting for fake law enforcement or fire charity funds and becoming evasive when pressed for organizational details |
| Key Risk Indicator | Automated threats about SSN being used for criminal activity, civil complaint notices demanding immediate settlement, unexpected PCH prize notifications, or requests to verify banking details over the phone |
| Safety Tip | The Social Security Administration never calls to threaten legal action — they send letters through U.S. mail. Publisher's Clearing House Prize Patrol shows up in person with a camera crew. Real prizes never cost money to collect |
