Will You Lose Your Phone Number If You Switch Telcos?
Moving telco providers can be nerve-wracking for any organisation. But porting a phone number that's been with your business its entire history can feel like something closer to terror.
It makes sense why. That number is on every flyer, every piece of signage, every donor letter for years - sometimes decades. It's the one thing an elderly donor, a person in crisis, or a long-term supporter has memorised and trusts. Losing it doesn't feel like a technical change. It feels like losing continuity with everyone who's ever relied on you.
Here's the part that gets missed: porting a number is typically seamless. It needs proper preparation, the right documentation, and coordination on timing - but that's standard process for any competent telco, not a leap of faith.
Below, we've answered the questions we get asked most often by organisations considering a switch - so you can make the decision based on how porting actually works, not the fear of what might go wrong.
Number Porting: Your Questions Answered
Will we lose our phone number if we switch providers?
No. Moving to a new telco does not mean getting a new number. Porting lets you keep your existing number exactly as it is while your service moves to the new provider. This applies to landline, mobile, and 1300/1800 numbers.
How long does number porting take?
Most ports are completed within a few business days once the right documentation is submitted. Complex ports - such as numbers with multiple services attached — can take a little longer, which is why timing and preparation are agreed upfront rather than left to chance.
Is there downtime while the number ports?
When it's planned properly, no. A good provider schedules the port for a low-traffic window and coordinates the cutover so calls keep connecting throughout. Any disruption is almost always the result of missing paperwork or poor timing, not the porting process itself.
What information do we need to provide to port a number?
Typically your current account details, the number(s) being ported, and authority to port from the account holder. Your new provider should tell you exactly what's needed upfront and handle the coordination with your old provider directly - you shouldn't be left to chase this yourself.
Can we port a number that's decades old, or tied to a founder who's no longer with the organisation?
Yes. The age of the number or who originally set it up doesn't affect whether it can be ported. What matters is that the current account holder can authorise the port - this is a documentation step, not a technical barrier.
What's the difference between porting and getting a new number with call forwarding?
Porting transfers full ownership and control of your existing number to the new provider - it becomes your number, on your new service. Call forwarding just redirects calls from an old number you no longer control. Porting is almost always the better long-term option for an organisation whose number is part of its identity.
Does porting affect our ability to move to a cloud-based phone system?
No - in fact, porting is usually the first step. You can move to a cloud PBX with better call handling, routing, and reporting while keeping the exact same number your donors and clients already know.
What "Proper Preparation" Actually Looks Like
Confirm account details matchThe name and address on your new order need to match your current provider's records exactly. This is the single most common cause of a delayed port. |
Agree a cutover windowChoose a time with the lowest call volume - sometimes that is outside business hours or over a weekend. |
Map every number in useMain line, direct lines, fax, EFTPOS - anything attached to your account needs to be identified before the port, not discovered afterwards. |
Get it in writingA confirmed timeline from your new provider - not a vague "it'll be sorted" - is what separates a seamless port from a stressful one. |
