1300 Numbers Australia: Cost, Rules, and Setup Guide

What Is a 1300 Number?

This guide explains everything Australian small businesses need to know about 1300 numbers: how they work, what they cost, ACMA regulations, and whether one is actually worth it for your business. Written by an independent editorial team, not by a number provider. By the end, you will know the real costs (not just the advertised ones), the regulatory rules you must follow, and how to set up a 1300 number on a modern VoIP phone system. Technically, 1300 numbers are classified as 'Local Rate Numbers' under Australian telecommunications regulation administered by the ACMA (Australian Communications and Media Authority). The number itself does not have a physical location. It is a routing number that forwards calls to a nominated destination, which can be a landline, VoIP number, or mobile.

1300 vs 1800 Numbers: What Is the Difference?

For most Australian small businesses, 1300 numbers offer the best balance of caller experience and cost. 1800 numbers are more appropriate for businesses that want to maximise inbound call volume and can absorb the higher per-minute termination costs.

How 1300 Number Calls Are Charged

When someone calls your 1300 number, the call is forwarded to your nominated destination number (your VoIP extension, office landline, or mobile). You as the business pay the call forwarding charges. These charges vary by provider and destination type.The key cost components are: the monthly number rental fee, the per-minute or per-call forwarding charges to your nominated destination, and optionally call management features like time-based routing or IVR menus (which may incur additional fees). Calls forwarded to VoIP numbers are typically cheaper than those forwarded to mobile numbers.

How to Get a 1300 Number

1300 numbers are supplied by Australian telecommunications carriers and resellers. You can obtain one through: a hosted PBX provider (many include 1300 numbers in their plans or offer them as an add-on), a dedicated inbound number provider, or directly through a carrier. If you are setting up a hosted VoIP phone system, check whether 1300 number support is included before choosing a provider.The number assignment process involves: choosing a number from available stock (some providers let you select a memorable or 'smart' number for a higher fee), nominating the destination number where calls will be forwarded, and configuring any call routing rules (time-of-day routing, overflow to voicemail, etc.).

For a step-by-step walkthrough of the full application and setup process, see our guide to how to get a 1300 number in Australia.

If you are setting up a hosted VOIP system, ask your provider whether 1300 numbers are included in standard plans or available as an add-on. Most specialist VOIP providers handle the number application process on your behalf as part of onboarding. You choose a number from available stock, and they manage the setup and routing to your service. This is simpler than applying directly and means your 1300 number is configured to work with your phone system from day one.

1300 Numbers and VoIP Phone Systems

Modern hosted PBX and VoIP systems integrate well with 1300 numbers. When a 1300 number is forwarded to a VoIP extension, it arrives like any other inbound call. Your auto attendant, ring groups, and call recording all work normally. The 1300 number is simply a public-facing number that routes into your VoIP system.This also means you can use the same 1300 number with multiple VoIP extensions across different locations or remote workers. Time-of-day routing can forward calls to your office extension during business hours and to voicemail or a mobile outside of hours. See our hosted PBX guide for more on how inbound number routing works.

Can You Port an Existing 1300 Number?

Yes. Australian 1300 numbers can be ported between providers in the same way as geographic numbers. If you have an existing 1300 number with a current provider and want to move it to a new hosted PBX provider, the new provider can initiate a port request. Porting timelines vary but typically take 5 to 15 business days. During porting, your existing 1300 number continues to forward calls until the port is complete. If you are still deciding between VoIP and your current phone setup, our VoIP vs traditional phone comparison covers the full trade-offs.

1300 Number Pricing in Australia: What You Will Actually Pay

The cost of a 1300 number in Australia has two components: the number rental fee and the per-minute inbound call charge. Unlike calling a standard geographic number where the caller bears the cost, 1300 inbound calls are charged partly or wholly to the business receiving the call. Understanding this structure before you commit to a plan is important, because the total monthly cost depends heavily on your inbound call volume.

Number rental fees typically run from $10 to $40 per month depending on whether the number is a standard (non-memorable) number from available stock or a selected number with a specific pattern. The rental fee covers the number assignment and routing rights. On top of this, you pay a per-minute inbound call charge for calls received on the number. Standard 1300 inbound rates from Australian carriers range from approximately $0.05 to $0.15 per minute for calls from landlines, with mobile calls typically attracting a higher rate ($0.15 to $0.25 per minute) because mobile carriers charge termination fees. Some plans bundle a set number of included minutes per month before the per-minute rate applies.

To calculate your realistic monthly cost, estimate your inbound call volume (number of calls per month multiplied by average call duration in minutes) and apply the per-minute rate to that figure. Add the rental fee. For a business receiving 200 calls per month averaging three minutes each, the inbound charge at $0.10 per minute would be $60 per month, plus the rental fee. At $200 calls: $60 plus $20 rental equals $80 per month total. This is a manageable cost for most businesses, and should be weighed against the professional credibility and national reach a 1300 number delivers.

Vanity 1300 Numbers: Are They Worth the Cost?

A vanity 1300 number is a number that spells a word or phrase on a telephone keypad: 1300 PLUMBER (1300 758 623), 1300 LAWYER (1300 529 937), or similar. These numbers command a premium because they are memorable, easy to advertise, and directly communicate your service category. The premium varies depending on how desirable the word is and whether the number is already in use and available for purchase from its current owner.

Acquiring a vanity number typically involves searching a number broker or carrier's available inventory, or approaching the current owner of a desired number if it is already registered. Prices for desirable vanity numbers range from a few hundred dollars to tens of thousands for the most sought-after combinations. The annual rental fee on a vanity number is usually no different from a standard 1300 number once it is in your name. The premium is the acquisition cost, not the ongoing cost.

Whether a vanity number is worth the investment depends on your marketing context. For businesses that advertise on radio, outdoor signage, or in print where a memorable phone number has direct conversion value, a vanity number can pay for itself quickly. For businesses where customers primarily find you through Google search and click-to-call, the memorability advantage of a vanity number is less significant. If you are evaluating a vanity number, consider whether your customers are likely to remember and manually dial your number versus finding you digitally and calling from a search result or website.

1300 Numbers for Multi-Location and Remote Businesses

One of the most underappreciated advantages of a 1300 number for Australian businesses is the ability to route inbound calls flexibly regardless of where your staff are located. A 1300 number is not tied to a physical location or a single phone line. It is a virtual overlay number that can be configured to route to any destination: a hosted PBX, a geographic number, a mobile, or multiple destinations simultaneously.

For a business with staff across multiple locations, a single 1300 number can present a unified front to callers while routing internally based on time of day, caller location, or IVR selection. A customer calling from Brisbane routes to the Queensland office during business hours and failovers to the Sydney team if the Brisbane office does not answer. After hours, the call routes to a voicemail-to-email box monitored by whoever is on call. This level of sophistication is available without complex IT infrastructure, because it is managed through your hosted PBX provider's call routing configuration.

For businesses where staff work from home or from different locations, a 1300 number integrated with a hosted PBX means the caller experience is seamless regardless of where your team physically is. The business number rings all extensions simultaneously, or in a round-robin pattern, or through an auto attendant. The caller has no visibility into the distributed nature of your operation. This is a meaningful operational advantage for small businesses competing against larger organisations with established physical presence.

Common Mistakes When Setting Up a 1300 Number

The most common mistake is setting up a 1300 number without a proper phone system behind it. Some businesses acquire a 1300 number and route it directly to a single mobile phone or geographic number. This works, but defeats most of the purpose. Callers cannot be queued, held, or transferred. If the single destination number is busy, the 1300 call fails. If the mobile owner is unavailable, there is no after-hours message. A 1300 number is most effective as the inbound layer of a properly configured hosted PBX, not a simple forward to a mobile.

The second common mistake is choosing a carrier without checking porting rules. Some carriers offer 1300 numbers on contracts that make porting expensive or restrictive. If your business grows, changes direction, or you find a better provider, you want the flexibility to move your 1300 number without paying a significant exit fee or fighting a porting dispute. Ask any provider about their porting terms before committing to a contract. Under ACMA rules, 1300 numbers are portable, but contract exit fees are a separate commercial matter.

The third mistake is not testing the routing thoroughly before going live. A 1300 number with misconfigured routing can present customers with a dead number, an endless ring, or an unexpected voicemail box. Test inbound calls from both landlines and mobile phones, at different times of day, including after-hours. Test what happens when all extensions are busy. Test the failover path. Document your routing configuration so that if something changes (a staff member leaves, an extension is removed), you know exactly what needs to be updated.

Your Next Steps

1. Decide if you need a 1300 or 1800 number. If your customers are other businesses (B2B), a 1300 number signals professionalism. If you serve consumers who expect free calling, consider 1800.
2. Choose a number. Standard numbers are often free to activate. Vanity numbers (easy-to-remember patterns) cost more but have measurable recall benefits.
3. Set up through your VoIP provider. If you already have a hosted PBX, your provider can usually provision a 1300 number and route it through your existing phone system. See our phone system guide for provider recommendations.
4. Configure call routing. Decide where 1300 calls go: ring group, auto-attendant, specific extension, or mobile fallback after hours.
5. Check ACMA advertising rules. If you advertise the 1300 number, you must also display a geographic or mobile number alongside it in certain contexts.Want help choosing between a 1300 number and other options? Get a free recommendation.

How much does a 1300 number cost in Australia?

A 1300 number typically costs between $15 and $50 per month in Australia, plus per-call or per-minute forwarding charges. The monthly rental covers number provisioning and basic call management features. Forwarding charges depend on the destination: VoIP numbers are cheapest (often 2-5c/min), landlines are slightly more, and mobile numbers are highest (typically 12-20c/min). Exact pricing varies significantly between providers.

Can callers from mobile phones call a 1300 number?

Yes, 1300 numbers can be called from any Australian phone including mobiles. However, mobile callers pay their standard mobile call rate (not a local rate) when calling a 1300 number. This is a common source of confusion. Only calls from fixed landlines are charged at local call rates. For callers who want a number that is genuinely free from mobiles, an 1800 number is required.

Can I choose my own 1300 number?

You can choose from available 1300 numbers in a provider's number pool. Most providers let you search for numbers and select from those available. 'Smart' or 'gold' numbers (e.g. 1300 FLORIST or sequences like 1300 123 456) attract a premium setup fee as they are in higher demand. If your current 1300 number is with another provider, you can port it rather than choosing a new one.

What happens to a 1300 number if I switch my phone system?

Your 1300 number can be pointed to a new destination at any time through your provider's portal. If you change your phone system, you simply update the forwarding destination from your old system to your new VoIP extension or phone number. If you also switch 1300 number providers, you can initiate a port to transfer the number. You do not lose the number when changing phone systems.

Can a 1300 number receive SMS messages?

1300 numbers in Australia are not SMS-capable by default. The 1300 number format is designed for voice calls only. If you need a business number that can both receive calls and SMS messages, you would need a mobile number or a virtual mobile number (VMN) instead. Some businesses operate both: a 1300 number for inbound calls and a separate mobile number published for SMS enquiries. Confirm SMS requirements with your provider before assuming a 1300 number covers all inbound channels.

Is there a difference between a 1300 number and a 1800 number for a small business?

The key difference is who pays for the call. With a 1300 number, callers from landlines pay a local call rate (typically around $0.25 to $0.55 depending on their carrier plan), while the business pays a per-minute inbound charge for the call. With a 1800 number, the call is free to the caller from any phone (landline or mobile), and the business pays the full inbound cost. For a small business with a primarily local or regional customer base, a 1300 number is usually sufficient. A 1800 number is more appropriate when you want to maximise inbound call conversion by eliminating any cost barrier for the caller, which matters more at scale.

How long does it take to get a 1300 number?

New 1300 number assignments from available stock typically happen within one to two business days of completing the application with a carrier. The number becomes active and routable within that timeframe. If you are porting an existing 1300 number from another carrier, the process follows the standard number porting timeline of five to ten business days. You can begin using the new number as soon as it is assigned, well before any porting is required, and update your website and marketing materials from that point.
