A2P SMS regulations in Spain.
Compliance with CNMC + AEPD rules and sender-ID registration.
A2P SMS to Spain is regulated by the Comisión Nacional de los Mercados y la Competencia + Agencia Española de Protección de Datos (CNMC + AEPD). Alphanumeric sender IDs (aliases) must be registered in the CNMC alias registry, mandatory since 15 September 2026; the CNMC decides within 1 month. GDPR + LSSI-CE + AEPD enforcement. BroadNet carries this traffic over direct operator connections.
Who regulates A2P SMS in Spain?
Application-to-person messaging to Spain is overseen by the Comisión Nacional de los Mercados y la Competencia + Agencia Española de Protección de Datos (CNMC + AEPD), which licenses the operators that terminate A2P traffic and sets the conditions those routes run under. BroadNet delivers into Spain over direct operator connections — Movistar, Vodafone Spain, Orange Spain and MásMóvil — 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: Comisión Nacional de los Mercados y la Competencia + Agencia Española de Protección de Datos (CNMC + AEPD).
- Direct operator routes: Movistar, Vodafone Spain, Orange Spain and MásMóvil.
- Sender-ID registration: mandatory in the CNMC alias registry (Registro de Alias) since 15 September 2026.
- Typical lead time: up to 1 month (the CNMC decision deadline).
Sender ID registration in Spain
Since 15 September 2026, operators in Spain must block SMS, MMS and RCS messages sent with an alias that is not in the CNMC alias registry (Registro de Alias), or sent through a provider the alias holder has not authorised. A registered origin provider files on the holder's behalf through the CNMC e-office, or the holder files in its own name; the holder then authorises the alias and shows its link to a brand, trade name, internet domain or company name. The CNMC decides within 1 month (3 months for bulk filings), and no decision by the deadline counts as a refusal — so register before you need the route, not during a launch.
- Registry: CNMC Registro de Alias, mandatory since 15 September 2026.
- Decision: within 1 month, or 3 months for bulk filings; silence means refusal.
- The alias must be linked to your brand, trade name, domain or company name.
- BroadNet coordinates the filing during onboarding.
Consent and content rules
GDPR + LSSI-CE + AEPD enforcement. Robinson List honoured. 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.
- GDPR + LSSI-CE: GDPR plus Spanish LSSI-CE. AEPD enforcement.
- Robinson List: Spanish opt-out list honoured network-wide.
- STOP / BAJA: Both Spanish opt-out keywords honoured.
What this means for your integration
Practically, three things decide whether traffic to Spain performs: a registered sender ID on a CNMC + AEPD-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 Spain 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.
