Australia Number Phone Formats
Australian number formats for business — 13, 1300, 1800 and their word variants — what each carries on the published record, and how to get one.
Australia number formats for business come down to three prefixes: 13, 1300 and 1800 — plus the word variant (Phoneword) that rides on any of them. The formats are the published products on this site, and each carries a caller arrangement that matters more than its digits. This page sorts the formats and shows the getting path.
The formats, one by one
- 1300 (ten digits): shared cost — the caller pays a local call cost and the business pays the remainder. Plans start at $10 per month.
- 1800 (ten digits): free for callers in the stated Australian 1800-number context; the business pays the call charges.
- 13 (six digits): the shorter format described in the published FAQ as typically used by larger national companies.
- Phoneword (word variant): a word spelled on the keypad after any of the three prefixes — 4 letters on 13, 6 letters on 1300 and 1800 bases — from $40 per month.
Choosing by caller arrangement, then availability
The format choice is really a caller-cost choice: 1300 for the shared arrangement, 1800 when callers should pay nothing, 13 where brevity fits the use case. Then availability decides the specific number: the Find a Number search lists available 1300 and 1800 Phonewords by word or last six digits, and the team confirms the exact number before connection — a search result is a snapshot, not a reservation.
What the formats do not carry
Stated plainly: no geographic area codes (the 02–08 landline prefixes are not published products here), no mobile-network numbers, and no coverage or presence claims anywhere in the published material. The formats are inbound business numbers connecting to the answering point named at signup. Service terms are governed by the terms and conditions.
