Compliance with IFT rules and sender-ID registration.
A2P SMS to Mexico is regulated by the Instituto Federal de Telecomunicaciones (IFT). IFT + operator sender ID registration. Spanish characters in UCS-2 or GSM-7, with approval typically taking 5-10 business days. LFPDPPP (Mexican Federal PDP Law) enforced by INAI. BroadNet carries this traffic over direct operator connections.
Who regulates A2P SMS in Mexico?
Application-to-person messaging to Mexico is overseen by the Instituto Federal de Telecomunicaciones (IFT), which licenses the operators that terminate A2P traffic and sets the conditions those routes run under. BroadNet delivers into Mexico over direct operator connections — Telcel, AT&T Mexico and Movistar Mexico — rather than through resold or grey routes, so the sender ID, the delivery receipt and the audit trail all come back from the licensed path.
- Telecoms regulator: Instituto Federal de Telecomunicaciones (IFT).
- Direct operator routes: Telcel, AT&T Mexico and Movistar Mexico.
- Sender-ID registration: IFT + operator sender ID registration. Spanish characters in UCS-2 or GSM-7.
- Typical lead time: 5-10 business days.
Sender ID registration in Mexico
IFT + operator sender ID registration. Spanish characters in UCS-2 or GSM-7. Registration is not a formality — an unregistered or mismatched sender ID is the most common reason otherwise-valid traffic is filtered, and the failure is usually silent rather than a hard rejection. Plan 5-10 business days for approval and register before you need the route, not during a launch.
- Lead time: 5-10 business days.
- BroadNet files sender IDs on your behalf through the IFT-licensed operators.
- Spanish: Spanish characters supported.
- Time to production: Live in 5–15 business days from test-access request to production.
Consent and content rules
LFPDPPP (Mexican Federal PDP Law) enforced by INAI. PROFECO consumer-protection rules. Transactional messages — one-time passcodes, delivery and account alerts — are treated differently from marketing, but the distinction is decided by the content of the message rather than by how the campaign is labelled.
- IFT sender ID: Sender IDs registered via operator route.
- LFPDPPP + INAI: Mexican Federal Personal Data Protection Law enforced.
- Spanish: Spanish characters supported.
What this means for your integration
Practically, three things decide whether traffic to Mexico performs: a registered sender ID on an IFT-licensed route, a consent and opt-out record you can evidence, and message content that matches the category it was registered under. BroadNet's compliance engine checks each submission against the Mexico ruleset before it reaches the operator, so a non-compliant send is rejected back to you rather than filtered silently downstream — which is the difference between a fixable error and traffic that quietly disappears.
- Every message returns a delivery receipt (DLR); BroadNet does not publish per-country delivery percentages.
