What are 13 Numbers?

A guide to 13 numbers in Australia

Image 1300number


YOU run a small or medium business and want that professional look. A customised 13 number is a great way to impress your customers, because it lifts your company profile.

With just six digits – 13 followed by four digits – these numbers are easy to remember. Six-digit numbers are short, punchy and customers can recall them in a snap. They can be matched with numerical sequences or phone words. Even large enterprises use 13 numbers to stand out from the crowd.

If you have a 13 number, a customer can get in touch with you from any fixed line in Australia and pay only the cost of a local call. However, fees apply when the customer calls from a mobile.

A 13 toll number allows your business to take control of incoming calls and direct them where you want almost in real time. With features such as call overflow, you will not miss out on calls – they will be diverted from a busy line to your selected number.

Your business gets a very professional image as callers to your 13 number are greeted with a tailored message. Your call is then routed to your mobile, your voicemail, or any designated line. Customer messages can be converted into audio files and sent to your email as attachments.
This Q & A provides a simple explanation of how 13 numbers work in Australia, what is the cost involved in establishing the service, what are the advantages to your business, and how you can go about obtaining your very own 13 number.

What are 13 numbers?

A 13 number is a four-digit number prefixed by 13. These numbers carry calls from the point they originate (the caller) to the answer point, where they terminate. These numbers are also referred to as inbound or virtual numbers or toll-free numbers.

Setting these numbers up is simple because they require no cabling system or costly infrastructure but use existing landlines and mobile networks throughout Australia. 13 numbers are said to “piggy-back” on the existing landline and mobile networks across Australia.

Customers can call your business from any Australian landline or mobile. Leading 13 provider Zintel Australia offers you flexible options like call overflow, voice to email, call announce to enable you to be in touch with your client enquiries around the clock.

How do 13 Numbers work in Australia?

Toll-free numbers are numbers that can be used anywhere, regardless of geography (unlike a fixed phone line). Inbound calls to these numbers are then directed to a landline or mobile service number. When a call is placed to a 13 number, the call enters the network and a search is conducted to find the relevant routing strategy that applies to the toll-free number. The routing strategy can consist of a number of options, which will determine where the call goes to. Once the routing strategy is established, the call proceeds to its destination. This all happens instantaneously, so the caller doesn’t experience any delay.

Can my 13 number be dialled from outside Australia?

You will need to research which countries can dial a 13 number in Australia. It may work for some countries, while it may not work for some others. If a caller can make contact with an Australian 13 number from overseas, they will be charged based on their home network’s rates. They will have to dial the overseas code of their country, followed by the Australian code (61), and then your 13 number.

13 Number benefits that will change your business.

A 13 number is short and punchy and easy to remember. Having that recall will prove invaluable for your business. The Australian Communications and Media Authority, the government body responsible for the regulation of broadcasting, the internet, radio communications and telecommunications, gives the example of 13 CATS.

A six-digit easy-to-recall number could become a marketing tool for your business if you have it on the side of a van or if a potential customer hears it on TV or the radio or sees it on your website. It gives your enterprise a professional look, branding it with a local and national appeal. Having a 13 number encourages customers all over the country to call at a low, local rate, thus helping give your business more reach.

How you manage your incoming call traffic is important to your operation. A 13 number allows you to redirect your inbound calls to other numbers or areas within your office. It also offers you the facility of diverting calls during times of busy call traffic. You can take your number with you wherever you move in Australia, thus increasing your mobility. You can also have audio voicemails sent to multiple emails of your choosing.

An ‘always-on’ 13 number ensures that your business is perennially connected to potential customers. A Call Routing strategy ensures your phone calls are redirected based on your preferences ie percentages, the time or day of the call, or geographic region of the call. If, for instance, your business has staff located overseas, your 13 number can be set up to be answered in several countries across the world.

Zintel’s routing solutions for 13 numbers include:

Call Distribution – splitting calls based on percentages, i.e. 50% to one answer point and 50% to an alternative answer point.

Postcode Prompting – prompting the caller to enter a postcode, to determine where their call is sent.

Regional Routing – routing the call based on the town or city the caller is in.

State Routing – routing the call based on the state the caller is in

Customised Greeting – presenting the caller with a greeting, and then prompting the caller to select a number to determine where their call is sent.
