Online Scams in Mexico: SAT, Banks, Common Fraud
Mexico's National Commission for the Protection and Defense of Users of Financial Services (CONDUSEF) registered over 6 million fraud claims in 2025, with digital fraud growing 25% year over year. Mexico's expanding digital payment infrastructure — including SPEI, CoDi, and mobile banking — combined with widespread use of WhatsApp and social media creates a rich environment for scammers.
SAT (Tax Authority) Scams
The Servicio de Administración Tributaria (SAT) is impersonated through emails threatening tax penalties, offering refund requests, or claiming your RFC (Registro Federal de Contribuyentes) has been suspended. These scams peak during tax declaration periods.
"SAT: Su situación fiscal presenta irregularidades. Para evitar sanciones, actualice sus datos fiscales en: [phishing link]. Referencia: SAT-2026-MX-4829." — A fake SAT message. The SAT never sends links requesting personal or financial information via email or text.
Access SAT services only at sat.gob.mx. The SAT will never request your e.firma password, banking details, or CIEC via email.

Banking and SPEI Fraud
BBVA México, Banorte, Santander, Citibanamex, and HSBC are all impersonated. Fake messages about "transferencias sospechosas" (suspicious transfers) and "bloqueo de cuenta" (account blocks) lead to phishing pages. SPEI (Sistema de Pagos Electrónicos Interbancarios) — Mexico's interbank transfer system — is exploited similarly to Brazil's Pix for social engineering attacks.
CoDi (Cobro Digital), Mexico's QR code payment system, faces QR code replacement scams at businesses and fake payment confirmations.
WhatsApp and Social Media Scams
Mexico has over 80 million WhatsApp users. Account cloning, fake emergency messages from "family members," and fraudulent business accounts operate at massive scale. Scammers impersonate CFE (Federal Electricity Commission), Telmex, and other utility providers through WhatsApp to collect payments.
Marketplace and E-commerce Fraud
MercadoLibre fraud includes fake sellers, counterfeit products, and phishing links that bypass MercadoLibre's secure payment system. Facebook Marketplace scams targeting Mexican users often involve fake deposits, phantom vehicles, and non-existent rental properties.
