Phone Numbers That Start With 1
Australian numbers that start with 1 in the inbound business context: how 1300 and 1800 numbers both begin with the digit 1, and what that means for callers.
In the Australian inbound business context, the numbers that start with 1 are the 13, 1300 and 1800 ranges — 1300 and 1800 numbers both begin with the digit 1, and so does the shorter 13 range that Phonewords can be built on. If a business number you have seen starts with 1, it is almost certainly one of these inbound types. This page explains that context. It does not catalogue every Australian service that begins with 1 — emergency, directory and operator services sit outside this site's products — and it makes no landline, mobile or area-code claims.
The inbound ranges that start with 1
- 1300 numbers: a ten-digit format — the 1300 prefix plus a six-digit number. A 1300 number is a shared-cost business number: callers pay a local call rate and the business pays the per-minute rates.
- 1800 numbers: the same ten-digit shape with the 1800 prefix. An 1800 number is free for callers in the stated Australian 1800-number context; the business pays the call charges.
- 13 numbers: the six-digit range that also starts with 1. A Phoneword can use a 13, 1300 or 1800 number, so all three ranges can present as a word on the keypad.
Why businesses use 1-prefixed inbound numbers
The shared prefix is the visible edge of a shared purpose: these are inbound numbers, published by a business so customers have one contact point to call. The differences between them are about who pays for the call and how the number presents. On a 1300 number the caller contributes a local call rate and the business pays the rest; on an 1800 number the caller pays nothing in the Australian context and the business carries the charge. A Phoneword changes the presentation rather than the cost structure — the digits spell a word, which is why availability and desirability affect Phoneword pricing, published from $40 per month.
Plans for these numbers are published at $10, $15, $39, $79 and $99 per month for both the 1300 and 1800 ladders, ex GST, with standard plans month-to-month. The current tables are on the pricing page.
What the prefix does not tell you
A leading 1 does not indicate where a business is located — these inbound numbers are not area-coded, and this page does not claim any geographic or local-presence effect for them. It also does not indicate device or network details; caller cost is defined per number type, not per handset. And a number starting with 1 is not automatically a business number — other Australian services use the prefix for their own purposes, and they are not covered here.
Numbers starting with 1: questions
Do all Australian business inbound numbers start with 1?
The 13, 1300 and 1800 ranges do — they are the inbound business numbers this site publishes. This page does not attempt a complete catalogue of every number range in Australia, so other 1-prefixed services are outside its scope.
What is the difference between a 1300 and an 1800 number?
Caller cost. On a 1300 number callers pay a local call rate and the business pays the per-minute rates. On an 1800 number callers pay nothing in the stated Australian 1800-number context and the business pays the call charges.
Can a number starting with 1 spell a word?
Yes. A Phoneword can use a 13, 1300 or 1800 number, so a word can be spelled on any of the 1-prefixed inbound ranges. Pricing starts from $40 per month and varies with the word's desirability and availability.
How do I find an available number that starts with 1300 or 1800?
Search Find a Number, which searches available 1300/1800 Phonewords. Availability is not guaranteed for any specific number. The 1300 numbers overview covers the range in depth, and 1800 numbers covers the toll-free side.
