Alltel 1300, 1800 and 13 Numbers help your business in various ways. While similar in function as virtual inbound numbers, there are differences between 1300, 1800, & 13 numbers that you should consider before choosing which is right for your business. These factors can be categorised into three: memorability, call cost for customers, and cost to the account holder.

How memorable does your inbound number need to be?

One of the most important features of inbound numbers is their high recall ability. But for businesses where memorability is not a priority, Normal issue 1300/1800 numbers are a great choice. These are random 1300 and 1800 numbers, trailed by six digits. What makes it better than a regular landline or mobile number is that their prefixes is automatically recognised by people as a business number.

For businesses that need a shorter mnemonic number, a normal issue number simply won’t do. Alltel 13 numbers are highly memorable inbound numbers which are only trailed by four digits. If you are willing to spend more for high recall ability, this is the inbound number for you.

Another option for businesses that want something memorable but don’t want to pay the annual government fees that come with 13 numbers are 1300/1800 Smartnumbers. These numbers come in combinations that correspond to words when dialed (1 300 ALLTEL or 1300 255 835) or come in repetitive patterns. Unlike normal issue numbers, these can be tailed by up to 10 digits.

So how do longer Smartnumbers work? Though longer than the standard 1300 and 1800 number, these function just the same. The only difference is that when you dial it, the provider will only recognise the first 10 digits of and ignore the extra digits. This is commonly known as overdialling.

How much does it cost to call 13, 1300, and 1800 numbers?

1300 numbers are also known as ‘Local Call’ numbers. The cost of calling a 1300 number from any Australian landline is fixed at local rates. This allows your business to expand your market beyond your local area by offering affordable call rates. The same goes for 13 numbers. 13 number calls are charged based on local rates.

On the other hand, 1800 numbers are commonly referred to as ‘Free Call’ numbers. Calls to 1800 numbers are free from any landline in Australia. These are great for customer service centres or as a consumer hotline.

All calls to 13, 1300, and 1800 numbers originating from mobiles are charged as determined by the caller’s mobile provider. There are mobile providers that offer ’13 friendly plans’ that include calls to 13 and 1300 numbers in their call allowance. Efforts are also being made to offer free mobile calls to 1800 numbers. Consumer groups, in cooperation with ACMA, have already successfully convinced a majority of mobile providers to make calls to 1800 numbers free.

What is the cost of getting a 13, 1300, or 1800 number for your business?

The account holder (business) pays as little as $14 per month for their inbound number service. The call rates you shoulder depend on whether you answer calls on your landline or on your mobile. Basic routing schemes like Australia-wide, State-based, Time and Day-based, Call splaying, and Call Forward come with your number at no added charge. Complex configurations and other optional add-on features can also be added to your plan for a low cost.
