CoDi had 21.8 million validated accounts at the end of September 2025. Those accounts had produced 17.8 million transactions in six years of operation. The Asociación de Bancos de México said in late August 2026 that banks will simplify CoDi and DiMo flows in their apps through unified function placement and fewer steps. ABM president Emilio Romano said CoDi is not for everyone nor for every payment.
CoDi is a platform developed by Banco de México to facilitate payment and collection transactions through electronic transfers at no cost. The payee generates a collection message, delivered by QR code or NFC, and the payer's acceptance triggers a SPEI transfer with instant confirmation to both sides. DiMo began operations in early 2023 as an additional service offered by SPEI participants that lets customers identify the beneficiary account by mobile phone number alone. Linking an account in DiMo is free, although transfers may carry a charge set by the customer's institution.
Banco de México reported 5.28 million registered DiMo users at the end of 2023. Sixteen participants were enabled on DiMo at that date, with 18 more in the process of joining. By November 2024 the central bank counted more than 11 million linked accounts across 21 institutions. BBVA México said in January 2025 that DiMo users had executed about 250,000 transactions since the service was created. Most CoDi accounts remain inactive, according to Fintech Expert.
Banco de México's Circular 9/2026 gives financial institutions until 14 December 2026 to complete the standardisation of SPEI, DiMo, CoDi and QR transfer flows in their mobile apps. From that date, entering the 18-digit CLABE or a debit card number will no longer be mandatory to complete a transfer. The ABM also intends to introduce automatic enrolment so that customers can use CoDi without a separate registration process. The December cutover is likely to be the first real test of whether simpler screens convert enrolled accounts into regular payments.
