Nearly Half of Mexicans Would Ditch Phone Numbers Over Data Registration, Survey Finds

A survey indicates 47% of Mexicans would rather lose their phone number than register their mobile line with personal data. 42% of respondents will complete the registration due to reliance on mobile phones for work and daily life. Concerns about data security, hacking, and potential government surveillance are significant among users.

Nearly half of Mexicans would prefer to lose their phone number rather than share personal data for the mandatory registration of mobile lines, according to a recent survey. The study by market research agency Research Land found that 47% of respondents would stop using their phone number if it meant avoiding providing personal information for registration. Conversely, 42% stated they would complete the process, citing their dependence on mobile phones for work, family contact, and daily activities.

The survey results were released after the regulatory authority extended the deadline for mobile line registration until December, implementing a staggered schedule. The study highlights that beyond operational challenges, significant concerns persist regarding the protection of personal data and user trust. Pablo Levy, general director of Research Land, noted, "The extension of the deadline provides more time to complete the process, but the results show that user confidence will remain an important element during its implementation. Communication, transparency, and certainty about information handling can help strengthen public perception of this measure."

Information security remains a primary concern for users. 40% of participants believe the main risk of sharing their CURP (unique population registry code) and other personal data is vulnerability to hackers. Another 29% fear their data could be used for phone-based extortion. Additionally, 20% expressed worry about potential government surveillance or control, while 11% reported no concerns about the handling of their personal information.

These anxieties arise in the context of recent cybersecurity incidents. In early 2026, a cybercriminal group claimed to have obtained 2.3 terabytes of information from at least 25 Mexican government agencies, potentially affecting up to 36 million individuals. This case reignited the debate on personal data protection held by public institutions. Globally, IBM estimated the average cost of a data breach in 2024 reached a record $4.88 million, underscoring the economic and reputational impact such incidents can have on both public and private organizations.
