What Can Be in a Phone Number
What can sit in a business phone number on the published record — prefixes, digits, mapped words — and what cannot (area codes, 0-and-1 letters, custom strings).
What can be "in" a phone number, on this record? The published business numbers have a fixed internal anatomy: a range prefix (1300 or 1800), a fixed-length span of digits after it, and — optionally — letters mapped onto those digits under the published keypad rules. What cannot be in them is just as definite: no area codes, no letters on 0 or 1, no arbitrary custom strings. This page walks the inside of the number.
What is in it
- The prefix: 1300 or 1800 — fixed by the range, and it carries the caller arrangement (shared cost on 1300; free for callers in the stated Australian context on 1800).
- The digit span: six digits after the prefix on 1300/1800 (four on 13) — standard numbers fill it with digits arranged through the team.
- Mapped letters: on a Phoneword, letters occupy the span through the published mapping — 2 = ABC through 9 = WXYZ. FLOWER maps to 356937; BAKERY to 225379.
What cannot be in it
Stated plainly: no area code — the numbers are state-neutral; no letters on 0 or 1 — those digits carry none; no custom digit strings beyond the word mapping; and no words longer than six letters (four on 13). Word pricing starts from $40 per month with availability and desirability affecting the word; candidates are searchable on Find a Number, with availability settling at the team's confirmation.
Plan rows run $10, $15, $39, $79 and $99 per month on the pricing page; no activation timeframe is published; terms sit in the terms and conditions.

Inside-the-number questions
Can letters and digits mix in one number?
The published mapping describes words occupying the span. Mixed letter-and-digit formats are not documented on this page — confirm specifics with the team.
Why can't my word contain a 0 or 1?
Those digits carry no letters on the keypad, so no mapped word can cross them.
Can I put my suburb's area code in the number?
No — area codes are not part of these numbers; they are state-neutral by design.
How long is the number altogether?
Ten digits for 1300/1800 (prefix plus six), six for 13 (prefix plus four).
