Key Takeaways
- Your business numbers are portable. Landlines, mobiles, 1300 and 1800 numbers can almost always move to a new provider, and your customers keep dialling exactly what they always have.
- Timeframes vary by type: mobile ports are usually same-day, a simple single line is typically a few business days, and a complex multi-line or inbound number port can take several weeks.
- Nearly every delayed port comes down to one thing - the details on the porting form not matching the losing provider's records exactly.
- Never cancel your existing service to "clear the way" for a port. That is the one mistake that can lose a number permanently.
- A well-planned port has no customer-visible downtime. The switch happens in a short cut-over window you choose, not a day of dead phones.
Ask a business owner why they're still with a provider they complain about constantly, and the answer is usually the same: "we can't risk the number." That number is on the vehicles, the invoices, the signage, ten years of Google results and every business card in the district. Losing it would cost far more than the monthly bill.
It's a fair concern, but it's based on an assumption that hasn't been true for a long time. In Australia, phone numbers are portable. When you switch providers, your numbers come with you. Here's exactly how that works, what to prepare, and where ports actually go wrong.
What Porting Actually Means
Porting is the industry process for moving a phone number from one provider (the "losing" provider) to another (the "gaining" provider). The number itself stays the same. What changes is which network is responsible for delivering calls to it.
It helps to understand the ownership question, because it trips people up. Strictly speaking, no business "owns" a phone number - numbers are allocated under Australia's national numbering rules and licensed for use. What you have is the right to use that number, and critically, that right travels with you rather than with your provider. Your current telco does not get to keep your number as a hostage when you leave.
That applies across the board:
- Fixed line and local numbers, including the numbers on an old copper service or a hosted phone system.
- 1300 and 1800 inbound numbers, which are the ones businesses worry about most because they're the ones on the advertising.
- Mobile numbers on business mobile plans, including numbers currently sitting on a staff member's personal account.
How Long It Takes
There's no single answer, because "porting" covers several quite different processes. Realistic expectations:
Mobile numbers: usually same day
A mobile port is the fastest of the lot. When the details match, it typically completes within a few hours of being lodged, often much less. This is why moving a whole team's mobiles is less disruptive than most managers expect.
Simple fixed-line ports: a few business days
A "simple" port is a single standard line with no unusual features attached to it. These generally complete within a small number of business days once the paperwork is lodged and validated.
Complex ports: allow weeks, not days
A port becomes "complex" when it involves multiple numbers, a number range or block, ISDN services, or a service with a phone system sitting behind it. Complex ports run to a longer industry timetable and commonly take several weeks from lodgement to cut-over. If you're migrating an office ahead of the copper and ISDN shutdown, build that time into your plan rather than discovering it at the deadline.
1300 and 1800 numbers: a few weeks is normal
Inbound numbers move under their own process and typically take a few weeks. The good news is that these are the least disruptive numbers to move, because the number itself just gets pointed at a new answering point when the port completes.
What You Need Before You Start
Ports get delayed for boring administrative reasons, not technical ones. Have these ready and you remove most of the risk:
- A recent bill from your current provider, ideally the most recent one.
- The account number exactly as it appears on that bill. Not the customer reference, not the invoice number.
- The exact legal entity name on the account. If the bill says "Smith Family Trading Pty Ltd" and your porting form says "Smith Plumbing", the port will reject.
- The full service address as the losing provider has it recorded, including unit or level numbers, spelled their way.
- A complete list of every number you want to move. Main line, direct numbers, fax lines that still take calls, 1300 and 1800 numbers, and every mobile.
- A signed customer authorisation. Only the account holder or an authorised representative can approve a port, which is a protection against numbers being moved without consent.
The single most common cause of a rejected port is a mismatch between what you believe your account details are and what your provider has recorded. When in doubt, copy the bill character for character.
The One Mistake That Loses Numbers
If you take nothing else from this article, take this: do not cancel your existing service before the port has completed.
It feels logical. You're leaving, so you close the account to stop being billed, and then move the number across. In practice, cancelling the service releases the number back to the network. Once released, it can go into quarantine and become effectively unrecoverable - and no provider, old or new, can conjure it back for you.
The correct order is always the same. Port first. Confirm calls are arriving on the new service. Then cancel whatever is left of the old service. A good provider will tell you when it's safe to close the old account, and will usually handle the cancellation timing as part of the migration.
What Happens on Cut-Over Day
For a well-planned port, cut-over is far less dramatic than people expect.
- The port is scheduled for a specific window, usually one you nominate. Choosing a quiet period (early morning, or outside trading hours for a retail business) keeps any brief disruption away from your busiest calls.
- At cut-over, call delivery switches to the new network. There can be a short window of minutes where a call could land on either service, which is why it's worth having someone watching both during the changeover.
- Your new service should already be built and tested before that moment. Handsets registered, call routing configured, voicemail set up, hunt groups and after-hours rules in place. The port then simply points live traffic at a system that is already working.
- Test immediately afterwards from an outside line: main number, each direct number, your 1300 or 1800, and a call out to check the number your customers see.
Nothing changes for your customers. Same number, same experience, and no need to update a single piece of signage or advertising.
Things Worth Checking First
A few situations need a conversation before you commit to a date:
- Contracts and early termination fees. Porting a number and exiting a contract are separate matters. The port can proceed, but check what leaving costs you.
- Bundled services. If your phone number rides on a bundle with internet, moving the number can affect the rest of the bundle. Plan the internet side of the move at the same time.
- Geographic limits. Local numbers move freely between providers, but they remain tied to their standard zone. Moving offices interstate is a different conversation from switching providers.
- Numbers on a staff member's personal account. These can port to the business, but the port has to be authorised by the person whose name is on the account, so have that conversation while the relationship is good.
- Emergency service address details. Once your calls run over an internet-based service, make sure the address registered against your numbers is current.
The Real Reason This Matters
Number portability exists precisely so that businesses aren't trapped with a provider that has stopped earning their custom. If you've been putting up with slow support, mystery charges or a system that no longer fits how your team works, the number was never the anchor you thought it was. That's exactly why so many Australian small businesses have moved on from the big telcos over the last few years.
The businesses that port smoothly all do the same things: they gather accurate account details up front, they list every number, they build and test the new service before cut-over, and they never, ever cancel the old service early.
