1300 Number Format: The Complete Anatomy

Format questions
What is the structure of a 1300 number?
Two parts: the 1300 service prefix and six service digits — 1300 XXX XXX. The prefix identifies a national, shared-cost inbound service; the digits identify yours. There is no area code at any position.
How is a 1300 number written internationally?
+61 1300 XXX XXX — the country code with a plus, then the prefix, then the digits. No leading zero needs dropping because there is no area code. Remember the caveat: the written form is correct but not diallable from overseas, since the range has no international route.
Why do some 1300 numbers read as words?
Those are phonewords: the six digits spell a word on the keypad — 1300 356 937 as 1300 FLOWERS. The diallable number is always the ten digits; the word is presentation, leased at a premium.
Every number format is a small language, and 1300 numbers speak a short one. Ten digits in two blocks, a prefix that replaces geography, and three presentation forms depending on audience. This page is the complete spec — the kind of reference to check before printing anything.
The structure
1300 XXX XXX — two parts, always:
- 1300 — the service prefix. In the position where geographic numbers carry a state area code, 1300 instead identifies a national shared-cost inbound service: callers pay a local-style rate from fixed lines, the business pays for the call received.
- Six digits — the service identifier, allocated as a fixed block. Ten digits total, the same length for every business on the range; the consequences of that fixed length are in 1300 number length.
The three presentation forms
| Form | Example | Audience | |---|---|---| | Domestic written | 1300 234 567 | Australian materials — the standard | | International written | +61 1300 234 567 | Documents and sites with overseas readers | | Spoken | "thirteen hundred, two-three-four…" | Radio, menus, verbal directions |
Formatting rules: blocks separated by spaces, no brackets, no dashes, the + written literally. The international form carries one honest caveat — it is the correct representation, but the range has no international route, so overseas callers cannot dial it; pair it with a +61 geographic alternative per 1300 number country code.
The word layer
The six digits map to keypad letters, which is where phonewords come from: 1300 356 937 spells 1300 FLOWERS, and over-dialling extends the trick — 1300 4SIMPLE presented as "1300 4 SIMPLE" while callers dial the underlying ten digits. The word tier carries a premium lease, and the economics are in smart numbers.
Common format mistakes
Three, seen constantly: adding an area code in front (the number is already complete — the classic mis-dial); hyphenating or bracketing (blocks and spaces read cleaner and dial cleaner); and assuming the +61 form is diallable abroad (it is not, for this range). Each mistake is prevented by the spec above.
The takeaway
Ten digits, two blocks, three forms, one caveat. The digits themselves are the only variable — pick them from the live pool on available numbers, and the product behind the format is on 1300 numbers, priced on the pricing page.
