Voice Call Compliance in Cameroon
A practical overview of the rules that affect voice call messaging and marketing in Cameroon, with a checklist before you launch.
Key Rules for Voice Calls in Cameroon
Telemarketing must respect consent and objections, and the Telecommunications Regulatory Board (ART) sets rules for operators.
Voice campaigns should use locally licensed numbers and follow consumer protection and data rules on direct marketing calls.
Data Protection
Cameroon adopted a personal data protection law in 2024, and its implementing measures are being phased in, so we check current requirements before campaigns.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Check whether the call is promotional or a service call, as the rules differ.
- Use permitted calling numbers and caller ID, and never hide or spoof the calling number.
- Screen numbers against any national do-not-call register before promotional campaigns.
- Call only within permitted hours in the recipient's time zone and keep recorded messages short.
- Offer an easy way to stop further calls and record call consent where required.
Contact data
Format numbers in international E.164 format with the +237 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
Cameroon follows the Africa/Douala time zone (UTC+01:00 in October 2026). The usual working week is Monday to Friday. Schedule voice call campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Douala, customers commonly use French, with English. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in Cameroon
Cameroon has growing mobile internet use, and WhatsApp and Facebook are the main channels for reaching customers. MTN Mobile Money and Orange Money are used for payments and transfers.
Law No. 2024/017 of 23 December 2024 introduced Cameroon's first comprehensive personal data protection framework, including consent requirements. Campaigns may need French and English versions depending on the region. Back-to-school, Christmas and New Year are key periods.
Cameroon is officially bilingual, with French dominant in eight regions and English in the North-West and South-West regions, so campaigns often need both languages. Its economy relies on oil, cocoa, coffee, cotton, timber and aluminium, and the Port of Douala handles trade for neighbouring landlocked countries such as Chad and the Central African Republic. Prices are in Central African CFA francs, pegged to the euro. Mobile money from MTN and Orange is the main way to pay, and the VAT rate is 19.25%.
Advertising Alongside Messaging
Advertising must be truthful and follow consumer protection rules.

Voice Call in Cameroon: FAQs
