Mexico's National Commission for the Protection and Defense of Users of Financial Services has launched a new section on its website that allows the public to check whether a telephone number has already been reported as suspicious and to register numbers linked to possible fraud calls or messages. The measure is designed to help users identify warning signs before becoming victims and to build a citizen-sourced database of suspected scam numbers. The authority presented the tool as a response to continued telephone fraud using social engineering and impersonation of financial institutions, tax authorities, e-commerce businesses and digital service providers. Between January and April 2026, CONDUSEF received 27,862 complaints, with 37.5% linked to possible fraud, and 54.7% of those cases associated with multiple banking institutions. The tool is already available on the CONDUSEF website.
