Sources: 5. Developments: 2. The Bank of Mexico (Banxico) has introduced new regulations, specifically Circular 10/2026, to simplify and standardize electronic fund transfers via mobile applications. To improve user experience and reduce errors associated with long digit sequences, the new rules allow users to move away from strictly entering 18-digit Standardized Banking Codes (CLABE) or 16-digit debit card numbers. Instead, transfers can be facilitated using alternative identifiers such as alphanumeric aliases, QR codes, or mobile phone numbers. Under the updated guidelines, mobile banking apps must implement a standardized four-stage process involving authentication, data entry, verification, and notification. For certain account levels (2, 3, or 4), users may associate the last 10 digits of their mobile number with their account to receive SPEI transfers upon request. Financial institutions have until December 14, 2026, to adapt their systems to these provisions. ## Timeline ### 2026-09-10: Banco de México introduces new rules for mobile bank transfers Banco de México is implementing new rules to simplify mobile bank transfers, allowing users to use phone numbers, aliases, or QR codes instead of long CLABE numbers to reduce errors. 3 sources. https://clstr.news/cluster/banco-de-mxico-introduces-new-rules-for-mobile-bank-transfers ### 2026-09-08: Banco de México simplifies mobile transfers with new identifier rules Banco de México is introducing new rules to simplify mobile transfers, allowing users to use aliases or phone numbers instead of the 18-digit CLABE code. 2 sources. https://clstr.news/cluster/banco-de-mxico-simplifies-mobile-transfers-with-new-identifier-rules --- Cite as: Mexico mobile banking transfer regulation updates.
