Changing a SASSA phone number
If your registered number changed, the old SIM was lost, or you cannot receive a one-time PIN, start by confirming exactly what changed. Many people confuse a SIM replacement with a full number change, yet the next step can differ.
Good preparation
Keep your own ID details, the application information and the correct contact record together. Avoid substituting another person's number unless the official process specifically allows it.
