Before we begin
AF2M (Association Française pour le développement des services et usages Multimédias Multi-opérateurs) is the regulatory body in France responsible for overseeing and coordinating messaging services across mobile network operators. It plays a key role in standardizing commercial and technical frameworks for SMS, MMS, RCS, and other mobile messaging services, ensuring compliance, transparency, and fair practices in the French telecom ecosystem. AF2M also works closely with operators and service providers to manage sender ID registrations and prevent fraudulent messaging activity.
Due to requirements in France, you must complete and return a Letter of Authorization (LOA) to Twilio in order to continue using Sender IDs to send messages to France.
To avoid potential traffic interruption, you must complete the LOA and send it to senderid@twilio.com
