Marketing SMS in Mexico are governed by the Federal Law on Protection of Personal Data Held by Private Parties (LFPDPPP), the Federal Consumer Protection Law (LFPC) and PROFECO’s “Registro Público para Evitar Publicidad” (REPEP). They require a prior, free, informed consent and respect for the do-not-contact registry.
Key requirements
| Requirement | What it means |
|---|---|
| Prior opt-in | Free, informed, specific consent (LFPDPPP) |
| Identification | Sender clearly identifiable in every SMS |
| Easy opt-out | Free and immediate (typically “BAJA” or STOP) |
| REPEP | Check the do-not-contact registry before campaigns |
| Records | Keep date, source and content of consent |
The REPEP registry
Mexican consumers can register their phone number on REPEP to block commercial messages. Even with a documented opt-in, you must verify your B2C lists against this registry before each campaign or risk a complaint.
Other rules
Sender IDs and short codes must comply with IFT (Federal Telecommunications Institute) rules. For an overview across countries, see SMS laws and restrictions.
