Short answer
Updated
Business SMS in South Africa is overseen by ICASA, with consent governed by POPIA and sending conduct by the WASPA Code of Conduct. Alphanumeric sender IDs of up to 11 characters need no pre-registration, but the name must identify your business. OmniChannels.ai, powered by BroadNet, sends over direct routes to Vodacom, MTN, Cell C and Telkom Mobile, and adds the WhatsApp Business API, RCS, voice and fallback in one platform.

What to know before sending in South Africa
A practical summary, not legal advice. ICASA, WASPA and Information Regulator requirements change, so we confirm the current position for your traffic during onboarding.
| Item | Details |
|---|---|
| Sender ID | Alphanumeric IDs of up to 11 characters are not pre-registered under the WASPA Code, but the name must identify your business. 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. |
| Use approved templates for business-initiated messages. Meta charges per delivered message by category, so check Meta's current rate card. | |
| Personal data | POPIA, enforced by the Information Regulator, applies to your contact lists. Keep only the data you need and confirm your approach with counsel. |

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.
