Overview

DID numbers to South Africa

A DID (direct inward dialing) number gives you a real South Africa number on your SIP trunk. It receives calls from local customers and, because you hold it, it is also the strongest caller ID you can present on outbound traffic to South Africa.

South African geographic numbers in Johannesburg, Pretoria, Cape Town and Durban are available with local documentation under RICA.

South Africa is a fast-growing English-language BPO hub serving the UK and Australia, and a destination with clear consumer-protection rules.

FAQ

South Africa DID numbers: FAQ

Can’t find what you need? Our routing team answers within the hour, around the clock.

Can I originate from a South African call center?

Yes. Many South African operations use our routes for UK, Australian and US traffic. Destination rules apply to the country you call.

Do you provide South African DIDs?

Yes, South African geographic numbers are available for inbound and as authorised CLIs.

Does POPIA apply to voice marketing calls?

POPIA section 69 covers electronic direct marketing, and the Information Regulator has indicated that it applies to voice calls. Treat consent or an existing-customer relationship as required.

How do power interruptions affect my calls?

Mobile towers can lose power during outages, temporarily reducing coverage. Expect more 480 responses in affected areas and retry later rather than marking numbers as dead.

Is there a national do-not-call list?

Consumers can opt out through industry registries, and the Consumer Protection Act provides for a national pre-emptive block. Keep your own opt-out records regardless.

What documents do I need for South Africa DIDs?

It depends on the number type. Many geographic numbers in South Africa require proof of a local address or business registration; toll-free and non-geographic numbers usually need less. The portal lists requirements per number type before you order.
