Area Code Overview
Area code 313 is one of Michigan's original 1947 area codes, now serving the City of Detroit and several inner-ring municipalities — Dearborn, Hamtramck, Highland Park, River Rouge, and Ecorse — after suburban areas split to 248 and 734. Detroit is the global center of the American automotive industry, home to Ford, General Motors, and Stellantis (Chrysler) headquarters and their massive supplier ecosystems. The city's population is approximately 630,000, with a predominantly African-American majority and a significant Arab-American community — particularly in Dearborn, which has the largest Arab-American population of any city in the United States. Wayne County, which 313 primarily serves, has one of the highest property tax delinquency rates in Michigan, a documented vector for specific fraud patterns.
Scam Patterns in 313
Automotive Recall Safety Notice Phishing
Detroit's auto industry workforce — including factory workers, suppliers, engineers, and dealers — receives regular legitimate NHTSA recall notices and manufacturer safety communications by text. Scammers impersonate the National Highway Traffic Safety Administration (NHTSA) or specific automakers (Ford, GM, Stellantis) with texts claiming a vehicle has an open safety recall requiring immediate dealer scheduling or a "compliance confirmation" click. Links harvest vehicle identification numbers (VINs), personal information, and dealer portal credentials. NHTSA recall alerts are published at nhtsa.gov and do not require clicking a link in an unsolicited text.
Wayne County Property Tax Delinquency and Auction Fraud
Wayne County manages one of the largest property tax delinquency and auction processes in the country — thousands of Detroit properties are offered at county tax auction annually. Scam texts impersonate the Wayne County Treasurer's Office claiming a recipient's property is facing imminent tax auction, offering to prevent it for an immediate fee paid by wire or CashApp. A separate variant targets investors browsing legitimate tax auction listings, offering insider "early access" to desired properties for a deposit. The Wayne County Treasurer does not conduct tax foreclosure outreach via text.
Detroit Water and Sewerage Department Shutoff Fraud
DWSD serves Detroit's residents with water and sewer billing. Scam texts impersonate DWSD claiming an account is past due and water service will be shut off within hours unless immediate payment is made via a provided link or prepaid card. Detroit's persistent water affordability crisis — where legitimate shutoff rates are high — makes these texts unusually believable. The City of Detroit's Human Rights Department has specifically warned residents about water shutoff scam texts targeting Detroit zip codes.
VoIP and Spoofing Risk Assessment
Risk Level: MODERATE
313 retains a larger share of legacy landlines than many comparable urban codes, reflecting Detroit's older housing stock and established business presence. This gives the code a moderate baseline legitimacy in line-type distribution. However, Detroit's economic vulnerability — documented high poverty and housing instability rates — makes residents particularly exposed to utility shutoff and property tax fraud, where financial stress reduces the window for careful verification.
What To Do If You Receive a Text From a 313 Number
Step 1: Verify auto recalls at nhtsa.gov using your VIN directly. Enter your VIN at nhtsa.gov/recalls to see all open recalls — no text link is ever necessary. NHTSA does not solicit compliance confirmations via text.
Step 2: Look up the number. Search at Who Sent That Text Message to check for prior reports, particularly for automotive recall fraud, property tax scams, or water utility shutoff texts.
Step 3: Contact DWSD directly for any water account questions. Detroit water billing is managed at detroitmi.gov/water or by calling 313-267-8000. Water shutoffs require mailed notice — not a text. See our guide on how to identify utility impersonation scams.
Step 4: Report. Forward to 7726 (SPAM). Report property tax fraud to the Wayne County Treasurer at waynecounty.com. Report water utility fraud to the Detroit DWSD. File with the FTC at reportfraud.ftc.gov.

Why are Wayne County property tax scams so effective in Detroit?
Wayne County's annual tax foreclosure process is real, well-publicized, and affects thousands of Detroit homeowners each year. When a scam text references an impending auction deadline with geographic and timing accuracy, it arrives in a context where many recipients know someone who has faced foreclosure — making the threat feel plausible. The Wayne County Treasurer's actual outreach occurs by certified mail; a text claiming to prevent foreclosure is a scam.
