When advertising a phone number for your business, two popular options in Australia are 1300 and 1800 numbers. Both are inbound, non-geographic numbers that help establish a professional presence. While similar, they work a little differently when it comes to cost and customer experience.
Here’s what you need to know:
1800 numbers (Toll-free)
ℹ️ Caller pays nothing. You cover the cost.
1800 numbers are toll-free for callers, which is perfect if you want to remove any barrier for customers calling your business. This makes them especially useful for nationwide customer service or marketing campaigns where you want to encourage high call volumes.
Best for:
- National reach.
- High-volume customer support.
- Businesses prioritising accessibility and customer experience.
1300 numbers (Shared-rate)
ℹ️ Cost is shared between your business and the caller.
1300 numbers offer a shared-cost model. Customers calling a 1300 number pay the cost of the call per their provider’s rates, while your business picks up the rest. It’s a great balance between affordability and accessibility. Note: Many modern mobile plans offer unlimited or included calls to 1300 phone numbers, meaning no extra cost for your customer.
Best for:
- Local or national businesses, e.g. franchises.
- Professional helplines and customer support lines.
- Companies managing large call volumes.
Which one is right for your business?
➡️ Want to maximise accessibility and remove costs for your customer? Go with a 1800 number.
➡️ Need a cost-effective option with nationwide reach? A 1300 number might be the better fit.
