Messaging Compliance in Tanzania
SMS, WhatsApp, voice and RCS rules for businesses messaging customers in Tanzania.
Overview
Electronic communications in Tanzania are regulated by the Tanzania Communications Regulatory Authority (TCRA). Bulk SMS runs through licensed providers with sender names registered with the operators, and promotional messages should be consent-based.
Tanzania's Personal Data Protection Act, 2022, overseen by the Personal Data Protection Commission, requires registration of data controllers and consent-based processing.
Swahili is the national language and widely used online, alongside English for business, so bilingual creatives often perform better.
WhatsApp is a leading business channel in many African markets; Meta's policies and the local data protection law both apply.
Voice campaigns should use locally licensed numbers and follow consumer protection and data rules on direct marketing calls.
Advertising Rules
Advertising should follow Tanzanian consumer protection rules and platform policies.

Regulators, Registers and Practical Rules in Tanzania
Tanzania's Communications Regulatory Authority (TCRA) regulates telecoms, and the Personal Data Protection Act 2022 is enforced by the Personal Data Protection Commission (PDPC), with which data controllers and processors must register. Direct marketing requires consent, and people can object to it. The Electronic and Postal Communications regulations also govern SIM registration and content. The main operators are Vodacom, Airtel, Yas (formerly Tigo) and Halotel.
