1800 Numbers Australia: What They Cost and Who Should Use One

What is an 1800 number?

An 1800 number is an Australian inbound freecall number. It always starts with the prefix 1800 followed by six digits, like 1800 555 123. When someone calls it, the call is free for them. The business that owns the 1800 number pays a per-minute charge to receive the call.

1800 numbers do not belong to a specific area code. They route to whatever phone line the business nominates. The line could be a Sydney landline, a Perth mobile, or a Brisbane call centre.

Here is what most businesses get wrong before buying one: an 1800 number is not a growth lever, it is a friction-removal tool. It reduces the cost-to-call barrier for buyers who were already going to call. It does not generate new demand. If you are reading this because you think a freecall number will lift enquiry volume, you probably need a different fix first.

How is 1800 different from 1300?

Both are non-geographic Australian numbers, but the cost structure is different. 1800 calls are free for the caller. 1300 calls cost the caller the price of a local call from a fixed line, and a per-call charge from a mobile that varies by carrier and plan. For the business owner, 1800 numbers cost more per call than 1300 because the business absorbs the caller's cost too.

• 1800 number = free for caller, business pays per call
• 1300 number = local-call rate for caller, business pays per call (cheaper than 1800)
• 13 number (6 digits) = same as 1300 but reserved for big national brands
• Geographic number (02, 03, 07, 08) = caller pays normal call rate, business pays nothing per call (line rental only)

What does an 1800 number cost a business?

1800 number pricing has two parts: a monthly platform fee that includes the number, attribution, and routing, plus per-minute usage charges billed on consumption. Through Gibson, 1800 numbers come inside the standard call tracking platform from $99/mo tiered packages. Per-minute usage rates depend on call origin (mobile calls cost the business more than landline calls).

“1800 numbers are about removing call cost as a barrier. The maths only works if the caller actually changes behaviour because the call is free.”

When should an Australian business use an 1800 number?

Four commercial scenarios where 1800 actually changes caller behaviour, rather than just adding cost to your phone bill.

• Customer service lines where existing customers might not call if it costs them anything. Retention is worth more than the call cost.
• Returns and warranty enquiries. You already lost the sale if a return is needed. Do not lose the rebuy too by making the caller pay to complain.
• Enterprise sales lines where a single deal pays for a year of 1800 traffic. Removing any friction at the consideration stage is rational.
• Direct-response B2C campaigns where call cost is a measurable psychological barrier. Insurance, finance, legal, and disability services typically benefit.

When does an 1800 number not make sense?

Three cases where 1800 adds cost without lifting outcome. First, local trades and professional services where the caller is committed (a plumber's customer is calling about a leak, not comparing). Second, businesses where 80% or more of enquiries already come from a single region. A 1300 number works for the same trust-signal effect at lower per-call cost, and a geographic number (02, 03, 07, 08) works even better. Third, any business that has not first solved its tracking problem. If you do not know which channel drives your calls, an 1800 number just makes the unattributable calls more expensive.

What is the better default for most Australian businesses?

A geographic tracked number (02 in NSW, 03 in VIC, 07 in QLD, 08 in WA/SA/NT) outperforms 1800 for most businesses spending under $50,000 a month on marketing. The local trust signal lifts call rate. Per-call cost is lower. Attribution is the same as any tracked number. The right time to add an 1800 to the mix is for a specific use case (customer service, returns, enterprise) on top of the geographic numbers, not as a replacement.

“1800 numbers solve a specific problem: call cost as a barrier. If that is not your problem, the number is a tax, not a tool.”

Can I track which campaigns drive 1800 calls?

Yes. Gibson treats 1800 numbers like any other tracked number. Each campaign, ad creative, or web page can have its own 1800 number, with the call attributed back to the source in real time. This works the same way for AI-engine attribution (ChatGPT, Google AI Overviews, Perplexity) as it does for Google Ads and organic search.

How do I get an 1800 number in Australia?

Three steps, 3 to 5 business days. Step one: pick the number from Gibson's available inventory, including memorable digit patterns where available. Step two: nominate where calls route (any AU or NZ phone line, mobile or fixed, with optional time-of-day rules). Step three: confirm the package tier. The 1800 number sits inside the standard call tracking platform from $99/mo tiered packages, so attribution, recording, and CRM integration are all included from day one. No setup fee. No lock-in. Monthly billing on consumption. If you are not sure whether an 1800 is the right shape for your business, the 15-minute call audit reviews your current setup and shows exactly which number ranges would actually move the needle, with findings delivered within 24 hours.
