The Number in a Phone Number
What the digits in a phone number actually carry — the prefix, the dialled digits, the word variant — explained from the published business number formats.
The number in a phone number is not one thing — it is a prefix that tells the caller what kind of call it is, plus the digits that identify the specific business line. On the published business formats here, that anatomy is easy to see: a 1300 number is the 1300 prefix plus six digits; an 1800 number is the same shape; a 13 number is the 13 prefix plus four digits; and a Phoneword makes the digits spell a word. This page unpacks each layer and what you can choose.
Layer 1: the prefix
The prefix is the part you cannot choose — it is fixed by the format, and it sets the caller-cost arrangement:
- 1300: shared cost — the caller pays a local call cost and the business pays the remainder.
- 1800: free for callers in the stated Australian 1800-number context; the business pays the call charges.
- 13: the six-digit format described in the published FAQ as typically used by larger national companies.
Layer 2: the digits
The digits after the prefix are the part you can shape. On a standard number they are chosen from what is available; on a Phoneword they are selected so the keypad letters spell a word, using the published mapping (2 ABC through 9 WXYZ). That is the whole difference between the two number styles — the digits carry either arbitrary digits or a word you chose. The Find a Number search accepts the word or the last six digits, without the prefix, and lists available 1300 and 1800 Phonewords as they stand today.
Layer 3: what the number connects to
Behind the digits sits the third layer: the answering point. The signup flow asks for the number the service will connect to — the line or system that actually takes the call. The published pages describe that step only; what happens to calls beyond it, and any device setup, is not documented and should be confirmed with the team if it matters to you.

Digits in a phone number: questions
How many digits does a 1300 number have?
Ten in total: the fixed 1300 prefix plus six digits. The word format uses those six digits to spell a word on the keypad.
Can I choose the digits after the prefix?
Within availability, yes — a Phoneword chooses digits that spell a word, and standard digits are selected from what is listed or discussed with the team.
What do the first digits of a business number tell you?
The prefix tells you the format and the caller-cost arrangement: 1300 shared cost, 1800 free for callers in the Australian context, 13 the shorter six-digit format.
Does the number itself ring a particular phone?
The published record says the signup flow asks for the number the service will connect to — your answering point. Beyond that step, the pages make no device claims.
