Choosing the right business phone number is an important branding and communication decision. The number you use affects how customers contact you, how professional your business appears, and how easily people remember your brand.
For Australian businesses, the most common options include:
- local phone numbers
- mobile numbers
- 1300 numbers
- 1800 numbers
- phonewords
This guide explains how each option works and how to choose the right number for your business.

Questions to Ask Before Choosing
When choosing a business phone number, consider the following.
1. Are you local or national?
If your business serves one suburb or city, a local number may be enough.
If you serve customers across Australia, a 1300 or 1800 number may be a better fit.
2. Do you want to look more established?
If professionalism and scale matter, a business number such as 1300 or 1800 usually creates a stronger impression than a mobile number.
3. Do you need flexible routing?
If calls need to go to different staff, locations or devices, a virtual number is usually the better choice.
4. Is advertising important?
If you are marketing heavily, a memorable 1300 number or phoneword can improve recall.
5. How cost-sensitive is your setup?
Mobile and local numbers are often cheaper initially, but they may limit your ability to scale or manage calls professionally later.
Common Business Number Scenarios

A mobile number or local number may be enough initially.

Customer Support Team
An 1800 number may be better if reducing caller cost is important.
National Brand Running Ads

Summary
The right business phone number depends on:
- your size
- your service area
- your brand goals
- your call handling needs
- your growth plans
For many small and growing Australian businesses, a 1300 number is a strong middle ground between professionalism, flexibility and cost.
If your business needs one national number that can route calls to the right people, virtual business numbers are often the most practical long-term solution.
