Chances are, there's a 13 number stuck in your head. Maybe from a catchy ad jingle, or just because it's easy to remember.

They're simple. They're memorable. But are 13 numbers actually good for business?

What is a 13 number?

13 numbers are six-digit numbers that start with 13, for example, 13 23 23.

They enable free inbound calls to your business from Australian numbers - and your business pays the call charge (currently 35c) on the caller's behalf.

What is a 1300 number?

1300 numbers are ten-digit numbers that start with 1300, for example, 1300 287 743. While they allow for using longer words as part of your number, they're otherwise harder to remember.

What's the difference between a 13 number and a 1300 number?

While they're collectively known as Smart Numbers, there are two main differences between 13 numbers and 1300 numbers. The first difference is, of course, the number of digits. 1300 numbers have ten digits an 13 numbers have six digits. The other difference is the cost. Australian Communication and Media Authority charges a monthly fee of $500 for use of 13 numbers. For 1300 numbers, the monthly fee is $1.

You can purchase 13 numbers and 1300 numbers (collectively known as Smartnumbers) from the Australian Communication and Media Authority. Your telco can also purchase them for you on your behalf.

13 and 1300 number is subject to an "allocation charge" that varies depending on the number's ACMA classification. The classifications are:

Platinum: Platinum numbers have a numeric pattern that makes them easy to remember. They are typically 13 numbers, such as 13 13 13 and some very memorable 1300 numbers, such as 1300 000 000. The allocation charge for Platinum numbers is $16,000 for 13 numbers and $20,000 for 1300 numbers.

Diamond: Diamond numbers are numbers that contain a memorable word, such as 13 4633 (13 HOME) or 1300 266 333 (1300 COMEDY). The allocation charge for Diamond numbers is $8000.

Gold: Gold numbers have a numeric pattern that is memorable, but not as memorable as Platinum numbers, such as 13 1000 or 1300 111 110. The allocation charge for Gold numbers is $6000 for 13 numbers and $4500 for 1300 numbers.

Opal: Opal numbers are numbers that contain a word that is not as memorable as Diamond numbers, such as 13 7246 (13 PACK) or 1300 272 263 (1300 APPEND). The allocation charge for Opal numbers is $2400 for 13 numbers and $1500 for 1300 numbers.

Silver: Silver numbers are numbers that contain a numeric pattern that isn't as memorable as Gold and Platinum numbers, such as 13 1123 or 1300 111 990. The allocation charge for Silver numbers is $1200 for 13 numbers and $1750 for 1300 numbers.

Standard: Numbers with no associated word or numeric pattern. The allocation charge for Standard numbers is $400 for 13 numbers and $250 for 1300 numbers.

Note: The numbers used as examples of each classification come from the ACMA's master list of numbers and their classifications. The prices quoted are those listed by the ACMA and are correct as of 4 August 2023.

13 numbers and 1300 numbers compared

  • Can position your business as premium.

The cons of a 13 number

  • High cost to use the number ($500 a month).

  • If you get a number previously used by another company, you risk wasting your business's resources dealing with a flood of wrong-number calls.

The pros of a 1300 number

  • Low cost for use of the number ($1 a month, a cost typically absorbed by your telco as part of your business phone plan).

  • Opportunity to get a number that's memorable for your business.

  • Premium "business-grade" number compared to traditional landline and mobile numbers.

The cons of a 1300 number

  • With ten digits, these numbers are harder to remember compared to 13 numbers

Case study: Was the 13 number worth it for this business?

Years ago, I had a client call asking how they could get a 13 number for their business. While we could easily register a 1300 number for them, getting the more premium 13 number would be a little more complicated.

I explained to the customer that you must buy these types of numbers through the Australian Communications and Media Authority (ACMA) at auction.

I directed the customer on where they can participate in these auctions on the ACMA website but also warned the customer that these premium 13 numbers can go for upwards of $10,000 with an annual fee of more than $8000. The customer didn't mind. They thought it was well worth the investment. A week or so later, they called me and said they'd got one.

We set up the number to ensure that calls to the 13 number would land on the hosted phone system we provided them. From a phone perspective, all was working well. Until calls to the number came flooding in…

On the new 13 number, they started receiving calls from customers asking for a different company. Curious, I Googled my client's new number. Sure enough, the 13 number they'd bought at auction previously belonged to another company. The company in question had been bought out by a larger organisation, and were now using their parent company's standardised number.

It would take time for these calls to stop. Or so we thought. Fast forward a year, and my client was still fielding thousands of calls for their number's previous tenant. In the end, we figured our client was wasting time and money fielding calls that weren't for them. So we decided to cancel the number, giving it back to the ACMA to auction off to another customer.

So, are 13 numbers worth the investment?

Whoever would become the next owner of that 13 number would have the same problem. Who knows, if they're a similar business, those wrong-number calls could be a lead generation opportunity and it might work out. But otherwise, if you are considering bidding for a 13 number, Google it first. That way, you'll make sure you aren’t getting a number that another organisation recently used.

Sure, my client's experience was a cautionary tale. But there are plenty of examples where 13 numbers have delivered astronomical returns on their relatively significant investment. Chances are if you can remember a 13 number, either from an ad or because you called an organisation on it, that 13 number was a good investment for that business. As for 1300 numbers, They're a more entry-level (and in many cases, affordable) alternative to the more premium 13 number.

And even 1300 numbers can make for some memorable advertisements:
