1800 Code Number
In Australia, 1800 is the code for toll-free business numbers. Callers pay nothing and the business pays a published plan from $10 per month ex GST.
The 1800 code is the prefix at the start of Australia's toll-free business numbers. A number starting with 1800 is free for the caller to dial in the stated Australian 1800-number context, and the business pays the call charges through its plan. Published 1800 plans start at $10 per month ex GST. This page covers the Australian 1800 code only; it does not describe toll-free ranges used in other countries.
What the 1800 code signals
A caller who dials an 1800 number is not charged for the call. The cost of receiving it — the plan's per-minute rate, billed per second — sits with the business. That is the defining behaviour of the code in the Australian numbering context, it holds regardless of which published plan the number sits on, and it is why the range is commonly used for service, support and sales lines where the business absorbs the cost of the customer getting in touch.
1800 code versus the 1300 code
The two Australian codes differ in who pays. On a 1300 number the caller pays a local call rate and the business pays the per-minute rate for receiving the call — a shared-cost model. On an 1800 number the caller pays nothing and the business carries the whole call cost. Neither code changes what a caller pays beyond that: the difference is the split, not the dialling experience. If you are weighing the two, the 1300 vs 1800 page compares them side by side, and the pricing page lists the same plan structure for both ranges.
Getting a number with the 1800 code
Published 1800 plans run from $10 to $99 per month and the standard plans are month-to-month with no lock-in. The tier structure mirrors the 1300 range: $10, $15, $39, $79 and $99 per month, with the $39 tier offered in three variants that split their included minutes differently. Each plan carries per-minute call rates and either included minutes or call credit depending on the tier; the current tables are on the pricing page. Because the caller pays nothing on 1800, the plan tier decides the entire cost of every call the business receives.
You can also search for an 1800 Phoneword — a number that spells a word on the keypad — using Find a Number, which shows available 1300/1800 Phonewords without promising the availability or price of a specific word.
