Resource CentreCountry-by-country compliance requirements for enterprise A2P messaging. All data cross-referenced from multiple sources and national regulatory bodies before publication.
The information in this regulatory index is compiled to the best of our knowledge from multiple independent industry sources. All data is cross-referenced and verified against at least two independent sources before publication and is updated as soon as changes are verified by two or more sources. Where sources conflict, we default to the most recent regulatory body guidance and note the discrepancy. Telecommunications regulations change frequently and without notice — always confirm requirements directly with local regulatory authorities and your messaging provider before launching campaigns. This index does not constitute legal advice.

Each country entry is checked against multiple provider documentation sources, then validated against the relevant national regulator’s published rules or press releases. Where a provider reports a change but no regulatory confirmation is yet available, the entry is flagged as provider-reported. Where the regulatory body has published a rule but providers have not yet updated, the regulatory source is primary. Each country card displays its specific verification sources.
