If you’re operating a business in Australia, it’s in your best interest to invest in the right tools to give you an advantage in your respective field. One tool that many local entrepreneurs often overlook is a business number, particularly an 1800 number.
1800 numbers are a special type of inbound phone number that can improve your customers’ perception of your brand and business. Unlike a traditional phone number, these numbers accommodate multiple callers simultaneously due to their built-in routing system.
Furthermore, unlike the more common 1300 number, 1800 numbers allow customers to call your business entirely free of charge, removing any cost barrier on the customer’s end.
There are pros and cons of using an 1800 number for your business, and it entirely depends on how you want to structure your customer service operations. Regardless of the reason, there are various providers that can offer your company an 1800 number with unique features, price points, and support levels.
If you’re curious to know the best 1800 number providers in Australia, then you’ve come to the right place. We’ll showcase some of the most notable 1800 number providers, as well as specific perks in each, to help you come to an informed buying decision.
Let’s jump right into it!
What is an 1800 number, firstly?
Before taking a peek at some of 2025’s best 1800 number providers, it’s important to understand what this number accomplishes in the first place.
An 1800 number not only distinguishes itself with a unique starting sequence from your standard phone number. It also has a host of features that make it a very useful business communications tool.
For starters, an 1800 number is a toll-free inbound phone number that customers from all over Australia can call at no cost to them. Because of this advantage, this number can encourage callers and customer engagement, as the cost-free features incentivise callers to pick up the phone.
Beyond that, 1800 numbers grant businesses operational flexibility: you can route calls to mobiles, landlines, VoIP systems or contact-centre queues; set time-based rules and IVR menus; record calls; and pull real-time analytics to spot trends and improve your service.
In essence, an 1800 number is a simple yet effective tool to help build your business’s touchpoint and accessibility. It also comes with a range of features, like a built-in dashboard, enabling your company to deliver top-tier customer service based on performance metrics taken straight from the tool.
With all that said, numerous providers in Australia offer 1800 numbers: What separates each of them from one another? In the section below, we’ll highlight some of the best 1800 numbers across various categories, from beginner-friendly providers to full-scale platforms.
Let’s jump right into it.
Best beginner-friendly 1800 number: Teleca
If you’re looking to get your first 1800 number for your call centre business, small enterprise, or not-for-profit organisation, but are unsure where to start, consider partnering with Teleca.
This 1800 number provider takes the crown when it comes to its affordability and its host of features, making it a great choice for growing businesses that want to scale their customer communication without spending a lot of time learning how the tool works.

Teleca doesn’t only have great 1800 numbers. Teleca’s inbound 1300 number plans are also excellent if you want to share costs with your customers for every call you take. If you want an Enterprise/High Volume plan, Teleca offers that as well, and the per-minute call rates are generally more favourable under that plan too.
