The Digits in an Australian Phone Number
An Australian inbound number here is 1300 or 1800 plus six digits — ten digits in all. How the digit structure works, and how the search uses it.
The digits in the Australian inbound numbers sold here follow a fixed structure: the 1300 and 1800 formats are the four-digit prefix plus a six-digit tail — ten digits in all — and the shorter Phoneword base, 13, adds four. The prefix is fixed and carries the caller arrangement; the tail is the part you choose. This page works the structure, and the practical consequences for choosing.
Which digits you actually choose
On a 1300 or 1800 number, all the choice sits in the six-digit tail. That is why the published search hint works the way it does — search the last six digits of the number you want, without typing the 1300 or 1800 prefix. The prefix is not decoration (it decides the caller cost), but it is not variable: two businesses comparing the same tail on both prefixes are choosing between caller arrangements, not between different tails.
How words live in the digits
Under the published keypad mapping — 2 carries ABC through 9 carrying WXYZ, with 0 and 1 carrying no letters — the tail can spell up to six letters. A six-letter word fills the tail exactly; shorter words leave spare digits; 0 and 1 in a tail mean no complete word fits it. On the 13 base, four letters fill the four digits after the prefix. The site's own 1300 327 934 shows the finished article, published as the Phoneword 1300 EASY DIAL.
Practical uses of the structure
- Search both directions: the tail you want and the word you want are different queries against the same listing on Find a Number.
- Read patterns: repeated pairs, ascending runs and sayable groupings are properties of the tail, visible before any word mapping is applied.
- Compare bases: the same tail can exist on 1300 and 1800 with independent availability — the digit structure makes that comparison possible.
- Stay within the format: a tail is exactly six digits on 1300 and 1800; shorter or longer sequences are not valid formats on these bases.

Reading a number's shape at a glance
The structure makes quick reads possible. Spoken groups — most tails are said as three-plus-three — determine whether the number scans when dictated. Repeat patterns — doubled digits, mirrored runs — mark tails that survive a noisy radio ad. Letter density — how many of the six digits come from a real word versus spare choices — tells you how much of the number's identity is load-bearing. None of these reads requires anything beyond the published format, and none of them promises outcomes; they are ways of seeing the digits, not claims about what the digits will do for the business.
Digit questions
How many digits is a 1300 number?
Ten: the 1300 prefix plus a six-digit tail. The 1800 format is the same shape, and the 13 base is six digits in total — 13 plus four.
Why does the search only want six digits?
Because the prefix is fixed, the six-digit tail is the only part that identifies availability. Searching the prefix adds nothing the format does not already fix.
Can a tail contain 0 or 1 and still spell a word?
Not completely — those digits carry no letters under the published mapping. A tail with 0 or 1 can still be a fine plain number; it just cannot spell a full word.
Does the digit structure differ between states?
No — the inbound formats are national, with no state component in the digits. Any page claiming state-specific digit patterns for these numbers would be beyond what this site establishes.
