How 1300 Numbers Work in Australia

A 1300 number works by sitting between your caller and the phones you already use. The caller dials ten digits, the network hands the call to the number's virtual exchange, and the exchange applies the business's routing rules to connect the call to a real answer point — a landline, a mobile or a call centre line. The caller pays up to the local call rate and the business pays the rest.

The journey of a 1300 call

1. The caller dials your number — 1300 plus six digits, from anywhere in Australia, with no area code.
2. The network recognises the 1300 prefix and passes the call to the virtual exchange attached to your number rather than to a physical line.
3. Your routing rules decide the destination. Simple setups send every call to one mobile or landline; more advanced rules sort by time, origin or keypress.
4. The call lands on a real phone. The answer point rings, the caller hears ordinary ringing, and the conversation proceeds exactly like any other call.
5. The cost is split. The caller is charged up to the local call rate; your business pays the remaining call cost against its plan, calculated per second.

Nothing in that journey needs new hardware. The number is a routing instruction, not a line — which is why a 1300 number keeps working when you move office, change carriers or answer on a mobile instead of a desk phone.

The routing rules a 1300 number can follow

Routing is the working part of a 1300 number. The modes available:

• Single destination. Every call rings one number — the setup most sole traders start with.
• Time-based routing. Business-hours calls go to the office; after-hours calls divert to voicemail-to-email, another number, or a message service.
• Location-based routing. Callers from different regions route to the office or representative that serves them.
• Overflow routing. Calls dial through a list of answer points in order, so a busy or unanswered phone hands the caller to the next instead of losing them.
• Round-robin routing. Incoming calls distribute across a team so the same phone does not take every enquiry.
• IVR / auto-attendant. Callers hear a menu — "press 1 for sales, press 2 for support" — and the exchange routes by keypress before any phone rings.

These modes combine: a common setup routes business-hours calls through an IVR into an overflow list, then switches to voicemail-to-email after hours.

The shared-cost model

A 1300 number is a shared-cost number. The caller contributes up to the local call rate — the same whether the business sits in the next suburb or across the country — and the business pays the balance of the call cost. For the caller, the number is affordable to dial; for the business, the per-call cost stays below what a fully toll-free 1800 number would cost, because every caller contributes something. 1300 vs 1800 numbers compares the two models call by call.

The business side bills as a monthly plan fee plus call charges. Plans run from $10 to $99 per month, cap inclusions absorb the first slice of call time at a fixed fee, and charging is calculated per second. 1300 number pricing works through the full cost structure.

The features layered on top

Because the number is virtual, features attach to the number rather than to a handset:

• Voicemail-to-email — after-hours messages land in your inbox as audio so enquiries are not lost overnight.
• Call recording — record inbound calls for training and quality review, with playback in the online console.
• Call reporting — volumes, durations and origins by day, so staffing and plans match real traffic.
• Number portability — bring an existing 1300 number with you when you change provider, and keep it when you relocate.

What a 1300 number does for a business

The mechanics translate into three practical benefits. One national number: a single contact point that never changes, advertised from Cairns to Hobart. A professional front: callers reach a routed, recorded, menu-sorted line instead of one person's mobile. Portable reach: the business can move, grow or redistribute its answering points without ever changing the number customers know. How the number presents to callers — local call rate, ten digits, no area code — is covered step by step in how to call a 1300 number.

If that model fits your business, choose a number from the available 1300 numbers pool, point it at the phone you already answer, and adjust the routing as your team grows. 1300 numbers covers the full product detail.
