What are freephone numbers?
Freephone numbers are special phone numbers that customers can call without paying. The organisation that owns the number pays for the call instead. They’re widely used for customer service lines, fault and emergency lines, sales enquiries and helplines, because removing the cost to the caller makes it easier for people to get in touch.
Freephone numbers are “non-geographic”: they aren’t tied to one location. Calls to them are routed through the phone network to whatever destination the owner chooses, such as a contact centre, an office or a cloud platform.
Freephone numbers in New Zealand
In New Zealand, freephone numbers begin with 0800 or 0508. Both are free for callers. 0800 is the most familiar to the public, while 0508 numbers work the same way and give organisations another range to choose from, which helps when looking for a memorable number.
Freecall and local-rate numbers in Australia
Australia has two common types of non-geographic customer service number:
- 1800 numbers (freecall). Free for the caller, with the organisation paying for the call.
- 1300 numbers (local-rate). Not free: the caller pays a charge, typically similar to a local call from a landline, and the organisation pays the rest. Charges from mobiles depend on the caller’s plan.
Both types can be routed anywhere in the country, which suits national organisations. Australia also has shorter six-digit 13 numbers, which work in a similar way to 1300.
How freephone numbers work
A freephone number is really a pointer. When someone dials it, the network looks up where the number should be delivered and sends the call there, often as a DDI number or directly into a cloud platform over SIP trunking. Routing can change by time of day, caller location or volume, so the same number can be answered by an in-house team during business hours and an after-hours answering service overnight.
Once the call arrives, the contact centre’s IVR and automatic call distribution take over, greeting the caller and connecting them to the right agent.
Why freephone numbers matter
- Accessibility. Customers who are worried about cost, including vulnerable customers, are more likely to call.
- Trust and recognition. A national freephone number signals an established, accessible organisation.
- Portability. The number stays the same even if the organisation moves offices, changes carrier or outsources its contact centre.
- Flexible routing. Calls can be spread across sites or partners, supporting business continuity.
Things to consider
Because the owner pays for every call, freephone costs rise with volume and with long waits on hold, so shorter queues save money as well as goodwill. Fault lines such as a utility fault line can see sudden spikes, so the number needs enough capacity behind it to keep accepting calls. And when changing providers, plan any number port carefully so customers never ring a number that doesn’t connect.
