13 Number Phone Numbers, Explained
The 13 number format — six digits, the shorter business number the FAQ describes as typical for larger national companies. What is and is not published.
A 13 number is the shortest Australian business number format published here: six digits, beginning with the 13 prefix. The published FAQ describes it as the shorter format typically used by larger national companies, and the Phoneword format table shows it carrying a word of up to 4 letters. This page sets out what is published about the 13 format — and just as clearly, what is not.
What is published about 13 numbers
- Format: the 13 prefix plus four digits — six digits in all, the shortest of the three business prefixes.
- Typical use: the published FAQ describes 13 numbers as typically used by larger national companies.
- Word variant: 13 Phonewords exist, carrying up to 4 letters on the keypad, per the published format table.
- Caller arrangement: the published FAQ's format comparison describes 13 numbers as sitting alongside 1300 (shared cost) and 1800 (free for callers) — but the published pricing page does not list 13 plan tables.
What is not published — and where to go
The pricing page publishes plan and rate tables for 1300 and 1800 numbers; it does not publish 13 plan pricing. No page on this site quotes a 13 monthly fee, a 13 call rate, or 13 availability — so this one will not either. If the six-digit format is the requirement, the honest path is to ask the team directly via the contact page about current 13 arrangements. Service terms are governed by the terms and conditions.
13 versus 1300: the short version
Both are shared-cost formats in the published comparison; the difference is length — six digits against ten — and the word limit that follows from it (4 letters on 13, 6 on 1300). The published FAQ frames 13 as the format typically used by larger national companies, which is descriptive rather than a rule: nothing published restricts who can hold one, and nothing published promises 13 availability for a specific number. The 1300 vs 1800 vs 13 comparison lays out all three formats.
