1300 Number vs Mobile vs Local Landline: Which Phone Number Is Right for Your Business?

23 February 2026 5 min read

You need a business phone number. But should you get a 1300, stick with your mobile, or use a local landline? Each has trade-offs. Here's what actually works—and what customers prefer.

Choosing a business phone number seems simple but isn't. A 1300 looks professional but costs money and requires infrastructure. A mobile is flexible and free but looks less professional. A local landline is trustworthy but ties you to one area.

Here's how to pick the right one for your business.

Option 1: 1300 Numbers

What It Is

A national landline number starting with 1300 (e.g., 1300 555 123). Calls are treated as local rates, no matter where the caller is in Australia.

Pros

Professional image. Customers instantly see you as established. 1300s signal you're not a solopreneur.
National presence. You look like a nationwide business even if you only operate in 1 suburb.
Local-rate calling. Customers everywhere pay local rates, increasing willingness to call.
Call routing. Calls can be routed to multiple team members or locations.
Professional voicemail & IVR. You can set up proper menus and call queuing.

Cons

Cost. $10–$30/month for the number, plus call charges (typically 7–15¢/minute). Setup: $100–$200.
Not geographic. Customers don't get local connection (if that matters to your area).
Requires PBX or provider. You need a phone system or VoIP service to run it.
Less SEO benefit. Unlike a local number, a 1300 doesn't help your local search ranking.

Best for: Established service businesses, multi-location companies, professional services (legal, accounting, consulting), any business wanting a national image.

Option 2: Mobile Number

What It Is

Your personal mobile number or a dedicated business mobile (e.g., 0412 345 678). Costs $30–$80/month depending on your plan.

Pros

No setup cost. Already have a mobile? Just use it. No infrastructure needed.
Flexibility. You can answer calls from anywhere—the office, your van, home.
Always reachable. Customers can reach you 24/7 (if you want).
Built-in features. Voicemail, call history, contacts—all standard.
Personal touch. Some customers prefer the informal feel of a mobile.

Cons

Less professional. Customers may assume you're a one-person operation (rightly so).
No call routing. Only 1 person can take calls. If you're busy, calls go to voicemail.
No professional IVR. No call menus, no queuing, no automated options.
Privacy concerns. You're mixing personal and business communications on the same device.
Harder to scale. When you hire staff, you can't easily route calls to them.
No geographic benefit. Doesn't help local SEO unless it's a local area code.

Best for: Solo traders, startups, flexible professionals, anyone getting started (before upgrading later).

Option 3: Local Landline (Geographic Number)

What It Is

A local number with the area code of your region (e.g., 02 for Sydney, 03 for Melbourne). Typically $10–$25/month through a landline or VoIP provider.

Pros

Local trust. Customers in your area see your area code and feel connected ("They're local").
SEO benefit. A local number helps your Google Business Profile ranking in your area.
Low cost. Cheaper than a 1300 and often cheaper than a mobile plan.
Professional voicemail. You can record a professional greeting.
Call routing. Depending on your provider, you can route calls to multiple people.

Cons

Geographic limitation. Only looks professional in your local area. Customers elsewhere may view it as regional.
Requires a phone system or VoIP. You need a provider; it's not as simple as a mobile.
Less call flexibility. Tied to a physical location or VoIP service (you can't easily take calls in your van like a mobile).
Higher call costs for distant customers. Long-distance calls to your landline may cost more (though rare in 2026).

Best for: Local service businesses (plumbers, electricians, cleaning, real estate), established businesses in a specific area, anyone wanting SEO benefit + professionalism without the cost of a 1300.

What Customers Actually Prefer

Research shows:

1300 numbers win on trust. 68% of customers rate 1300 numbers as "most professional." Trades and services see higher call volumes with a 1300.
Local numbers win on familiarity. If your customer is local, a local number (02, 03, etc.) creates comfort. "They're in my area."
Mobile numbers lose on professionalism. Only 22% of customers rate a mobile as highly professional for a service business. It works for trades where customers expect to reach you on-site, but hurts healthcare, legal, and corporate services.

How to Choose

Ask yourself these questions:

Are you a solo trader or growing a team? Solo → mobile or local landline. Growing → 1300 or local landline.
Do you operate in one location or nationwide? One location → local landline. Nationwide or multi-location → 1300.
Is your customer base local or spread across Australia? Local → local landline. Spread out → 1300.
Do you need to answer calls on the go? Yes → mobile or mobile + local landline. No → local landline or 1300.
What's your budget? Tight → mobile. Medium → local landline. Good budget → 1300.

The Smart Strategy

Many businesses use multiple numbers:

Mobile + Local Landline: Use a local landline for your website and marketing. Use your mobile as backup. Costs $10–$25/month, gives you professionalism + flexibility.
1300 + Mobile: Use a 1300 as your main business number. Route calls to your mobile for flexibility. Costs $30–$50/month but signals you're professional and scalable.

If you only pick 1: Choose based on your growth stage. Solo and local? Local landline. Established and growing? 1300. Just starting? Mobile, upgrade later.
