A numeric long code is available on select networks. | | Promotional messages | Send marketing only with verifiable consent, or to existing customers under POPIA's narrow exception, and always identify yourself. | | Sending hours | The WASPA Code bars direct marketing on Sundays and public holidays, on Saturdays before 09:00 or after 13:00, and on other days between 20:00 and 08:00. OTPs and alerts are transactional. | | Consent and opt-out | Keep timestamped consent records for at least 12 months. Every promotion carries STOP or opt-out wording, and STOP is honoured across campaigns. | | WhatsApp | Use approved templates for business-initiated messages.

Keep only the data you need and confirm your approach with counsel. | ## How to launch business messaging in South Africa 1. **Separate your traffic:** List your OTPs and alerts apart from promotions, and choose which use cases belong on WhatsApp and which on SMS. 2. **Set up consent:** Capture consent with the source, timestamp and wording, and plan one suppression list for STOP replies. 3. **Choose your sender IDs:** Pick a name that identifies your business, with separate names for transactional and promotional traffic. We prepare any filing with you. 4. **Connect WhatsApp:** Onboard through Meta Embedded Signup and submit your templates for approval. 5. **Test and launch:** Send test messages on all four networks, check delivery reports per network and schedule campaigns inside the allowed hours. ## Is this the right setup for your South Africa traffic? ### A good fit when - You send OTPs, alerts and promotions that must reach all four networks. - You need sending hours and opt-outs handled in the scheduler. - Your customers also use WhatsApp and you want one inbox for both. - You want delivery reports broken down by network. ### Good to know before you start - Marketing needs consent and a working opt-out, and a second consent request after a refusal is not allowed. - Promotions cannot go out on Sundays or public holidays. - Sender IDs need no pre-registration, but delivery still varies by network, so test each one. - Rules change, and we confirm current requirements at onboarding. ## South Africa business messaging questions ### Who regulates bulk SMS in South Africa? ICASA regulates electronic communications, the Information Regulator enforces POPIA, and WASPA is the industry body whose Code of Conduct binds its members and their clients. In practice your provider applies these rules to the traffic it carries. ### Do I need to register a sender ID in South Africa? No pre-registration is required under the WASPA Code, but the sender ID must identify your business. Alphanumeric IDs can be up to 11 characters, and a numeric long code is available on select networks. Test delivery on every network before launch. ### When can I send marketing SMS in South Africa? The WASPA Code bars direct marketing on Sundays and public holidays, on Saturdays before 09:00 or after 13:00, and on other days between 20:00 and 08:00. Transactional messages such as OTPs are not promotions. ### Do I need consent to send promotional SMS? Generally yes. POPIA section 69 requires consent before direct marketing by electronic communication, with a narrow exception for existing customers. Keep timestamped records and include your identity and an opt-out in every message. Confirm your approach with counsel. ### Which networks carry SMS in South Africa? Vodacom, MTN South Africa, Cell C and Telkom Mobile. OmniChannels.ai, powered by BroadNet, has direct routes to all four, and delivery reports show results per network. ### What happens when a customer replies STOP?

Yes, through the WhatsApp Business API with approved templates for business-initiated messages.
