Australian Phone Number Digits
How Australian 1300 and 1800 numbers are structured — a four-digit prefix plus six digits, the shorter six-digit 13 option, and how digits spell Phonewords.
For the business number types 1300 Easy Dial publishes, the digit structure is straightforward. A 1300 number or 1800 number is a four-digit prefix followed by six further digits — ten digits in total. The site's own number search reflects this: it asks you to type just the last six digits, because the 1300 or 1800 prefix is already fixed. A 13 number is the shorter variant at six digits, typically used by larger national companies. And in a Phoneword, those six trailing digits double as letters, spelling a word on the telephone keypad.
The 1300 and 1800 structure
Both number types share the same shape: a fixed four-digit prefix (1300 or 1800) plus the six digits that make your number yours. When you search or apply for one, the distinguishing part is those last six digits — which is why the Find a Number search tool asks for "the last 6 digits" and says there is no need to include the prefix.
The prefixes differ in what they signal to callers about cost. A 1300 number is presented as a shared-cost business number. An 1800 number is presented as free for customers to call in the stated Australian 1800-number context, with the business paying the call charges. Public plans for both start at $10 per month.
The shorter 13 option
A 13 number drops the long prefix: it is six digits in total and is typically used by larger national companies. A Phoneword can use any of the three prefixes — 13, 1300 or 1800 — so the word you want to spell can ride on the shorter or longer format. What differs between the families is call-cost treatment, not the way digits map to letters.
Digits that spell words
Telephone keypads put letters on the number keys, which is how a Phoneword works: the digits of the number spell a word when read through the keypad. Because a Phoneword is still a phone number, it can be dialled from any phone — the published FAQ puts it simply: numbers work on any phone, whether mobile, landline or VoIP. Phoneword pricing starts from $40 per month, with availability and desirability affecting the price of a specific word.
Choosing by structure and cost
Structure is the memorable part; cost is the ongoing part. A ten-digit 1300 or 1800 number with six digits of your own choosing — including digits that spell a word — pairs with published plans of $10, $15, $39, $79 and $99 per month, each with its own call-rate table on the pricing page. Prices are in Australian dollars and include GST. When you have a word or digit pattern in mind, search it first: availability is not guaranteed, and desirable words carry higher prices.
Phone number digit questions
How many digits does a 1300 number have?
Ten in total: the four-digit 1300 prefix plus six further digits. The number search on this site asks for just those last six digits because the prefix is fixed.
Is an 1800 number a different length?
No — an 1800 number has the same structure as a 1300 number: a four-digit prefix (1800) plus six digits. The difference between the two is call-cost treatment, not length.
How long is a 13 number?
Six digits in total. The published FAQ describes 13 numbers as the shorter option, typically used by larger national companies.
How do digits become a word?
Through the letters on the telephone keypad: a Phoneword's digits spell a word when read through the keypad, using a 13, 1300 or 1800 prefix. You can search available Phonewords by word or by digits.
