How Many Letters Can
My Phone Word Have?

You may have noticed that some Phone Words are longer than others.

The minimum number of digits required after dialing the 1300 / 1800 prefix is six. However most Phone Words are longer than six letters, and these ‘extra letters’ or digits are called Overdial. Phone Words with the ’13’ prefix have 4 letters after the prefix.


The maximum number of digits after dialing a 1300 / 1800 prefix is 10. The maximum number of digits after dialing a 13 prefix is 5.

Additional letters dialed are treated as ‘dead’ numbers and are ignored by the phone system, not affecting the call in any way.

In general, overdialing simply helps to make phone numbers easier to remember.

Keep your customers safe from your competition

You don’t want people to search through the yellow pages or the web for your phone number. It’s dangerous, as they can easily find some ‘new offer’ from a competitor and be snatched from you. Better to have a number that is on people’s minds straight away so they can call you directly.

Get more Leads and Bookings

This simple change makes all you’re marketing so much more effective as in example shown in the example of Focus Fitness above. This is because when people see your phone number they remember it (even they just see it in passing on a brochure or sign) and then can call when they get home at their convenience.

Develop a Large Company Brand Image

You only have 3 seconds to make a positive impression on your customers or they disappear from you like a ship in the night. This makes every phoneword, 1300 number, and smart number a great opportunity to brand your company in a very positive way.
