How Do 1300 Numbers Work?

A 1300 number works by acting as your business's front door on the phone network. The caller dials your ten-digit number — 1300 plus six digits — and the network delivers the call not to a physical line but to a virtual exchange that follows your instructions: ring my mobile, or the office, or the first free phone in a list. The caller pays up to the local call rate and your business pays the remaining call cost.

The three moving parts

The number. A 1300 number is a virtual number: ten digits, nationally dialable, not attached to any line, address or piece of hardware. That is why it moves with the business — point it somewhere else and it works identically from day one.

The routing rules. You choose where calls go and when. The simplest rule sends everything to one phone. More advanced rules split by time of day (office by day, voicemail-to-email after hours), by caller location, or through an overflow list that tries one phone and then the next. An IVR menu can sort callers by keypress before any phone rings.

The cost split. Every call is shared cost. The caller contributes up to the local call rate — the same from anywhere in Australia — and the business pays the balance against its plan, charged per second. Plans run from $10 a month, with cap inclusions that cover the first slice of call time at a fixed fee.

What the caller experiences

From the caller's side, nothing unusual happens: they dial ten digits with no area code, hear a ring or two, and talk. Depending on your setup they might meet an IVR menu first, or reach voicemail-to-email after hours. The full caller sequence is in how to call a 1300 number.

What the business sets up

1. Choose a number from the pool of available 1300 numbers — a standard number, or a phoneword that spells your brand.
2. Point it at an answer point — the mobile or landline you already use.
3. Add routing as you grow — time-based rules, overflow lists or an IVR menu.
4. Use the reporting to see volumes, durations and origins, and adjust the plan and rules to match.

There is no hardware, no technician and no new line; the number is virtual, so it answers on whatever phones you already run. If you already advertise a 1300 number with another provider, it can be ported across rather than replaced.

Where to go deeper

That is the whole system: a portable number, rules that decide where calls land, and a cost split that keeps the call affordable for both sides. The detailed mechanics — every routing mode, the feature layer and the setup sequence — are in how 1300 numbers work in Australia, the product overview is at 1300 numbers, and 1300 number pricing covers what it costs to run one.
