ICASA's authority over the numbering plan, licensing and Sender-ID conventions.
ICASA numbering plan, alphanumeric Sender ID and RICA: an indaba on A2P SMS traffic into South Africa
The Independent Communications Authority of South Africa (ICASA) regulates the +27 numbering plan and alphanumeric Sender ID. WASPA (the Wireless Application Service Providers' Association) administers the industry code of conduct. 4notify routes over tier-1 direct interconnects with Vodacom, MTN, Telkom and Cell C and registers Sender IDs per network, with RICA-aligned subscriber records.
Section 1 — In terms of the Electronic Communications Act 36 of 2005 and the WASPA Code of Conduct, this Indaba is convened on the delivery of A2P SMS traffic into South Africa and the registration of alphanumeric Sender IDs.
SIM-card registration; subscriber identity records for interception lawfulness.
Industry rules on consent, opt-out keyword handling and content delivery.
ICASA registration + operator agreements
4notify is registered with the relevant ICASA framework and holds alphanumeric Sender-ID agreements with all four operators.
Alphanumeric Sender ID registration
Brands register Sender IDs (e.g. "FNB", "TAKEALOT") with each operator. Required: CIPC company registration, sample message. Activation: 5-10 working days.
RICA-aligned subscriber records
Two-way numbers carry RICA-registered subscriber records; mismatched or unregistered ranges are flagged at the API edge.
STOP keyword handling (WASPA)
Every marketing message processes STOP and OPTOUT within the WASPA window and updates the suppression list across all four networks.

Do I need a South African entity to send SMS into South Africa?
No. 4notify manages tier-1 interconnects from EU infrastructure. For Sender-ID registration the brand provides CIPC company registration and a sample message; WASPA consent records remain with the brand as the content provider.
What is WASPA and why does it matter?
WASPA is the self-regulatory body for wireless application service providers in South Africa. Its Code of Conduct governs consent, opt-out keyword handling and content; non-compliance can lead to fines and suspension of short codes.
