ADT in South Africa is part of the Fidelity Services Group and trades as Fidelity ADT. It publishes separate emergency numbers for the coastal and inland regions, which is the most important thing to get right — an armed response call to the wrong region wastes time you may not have.
Official contact channels
- Emergencies, Coastal: 086 12 12 300
- Emergencies, Inland: 086 12 12 400
- Head office: 011 697 7000
- Customer care, coastal: [email protected]
- Customer care, inland: [email protected]
The coastal and inland split runs through both the emergency numbers and the customer care mailboxes. Establish which region your property falls into once, and record it — it applies to every future contact.
What this organisation provides
The regional split is not administrative convenience — armed response is dispatched from a control room covering a defined area, so the number you dial determines which control room receives the alarm.
Fidelity ADT provides armed response, alarm monitoring, and related security services to homes and businesses. Its website publishes a branch locator, because much of the service is delivered locally by the branch covering your suburb rather than nationally.
That local structure explains a common frustration. A national number can dispatch a response, but questions about a specific installation, a technician visit or a contract are usually resolved by the branch that services your address.
Address and operating information
ADT is a well-known international brand name, and in South Africa the business operating under it is Fidelity ADT within the Fidelity Services Group. Correspondence, invoices and email addresses therefore carry the Fidelity name rather than ADT, which sometimes causes people to think they have reached the wrong company.
Fidelity ADT does not publish a single public walk-in address on its contact page; it directs customers to the branch locator instead. Emergency lines operate continuously by the nature of armed response, though the site does not publish office hours for administrative queries.
Also note the page invites customers to update their contact details — worth doing, because an alarm activation is verified by calling the numbers on file, and out-of-date details are a common cause of a delayed or cancelled response.
Support and escalation routes
Keep the regional emergency number stored in the phones of everyone in the household, not only the account holder. An activation frequently happens when the person who signed the contract is not the one at the property.
For an activation or an emergency, call the regional number rather than emailing. For billing, contracts and technical matters, use the regional customer care mailbox and ask for a reference number.
Private security in South Africa is regulated by the Private Security Industry Regulatory Authority, which registers service providers and handles complaints about the conduct of registered security businesses. Contractual and billing disputes fall under general consumer protection through the National Consumer Commission.
