Nobody Owns a Phone Number, Including Us
Start here, because almost every confused conversation about 1300 numbers begins with the wrong mental model.
All Australian telephone numbers — geographic numbers, mobile numbers, and 13, 1300 and 1800 inbound numbers — are a national resource, managed by the ACMA on behalf of the Commonwealth of Australia. They are not property. They are not assets anyone holds title over. No business owns one and no telco owns one either.
So what does “owning your 1300” actually mean?
It means holding the rights of use. Somebody holds those rights for every number in service in Australia, and the entire practical question — can you take this number with you, can somebody take it from you, does the goodwill you have built accrue to you — reduces to whose name is against it. “Own it, do not rent it” is shorthand for “make sure the rights of use are in your business's name”, and that is a checkable fact rather than a matter of opinion.
This matters more for a 1300 than for anything else you have, because a 1300 number is the one piece of your telecommunications setup that appears in your marketing. A mobile number can be replaced with mild inconvenience. A number printed on a fleet of vehicles, a decade of signage and every invoice you have ever issued cannot.
Two Ways to Have a 1300, and They Differ
Australian businesses acquire inbound numbers by two quite different routes, and most owners could not say which one applies to them.
| Allocated by a provider | Acquired as a smartnumber | |
|---|---|---|
| How you got it | Your telco gave you a number from a block allocated to them, usually as part of signing up for a service | You bought a specific number through the ACMA numbering system, choosing it deliberately |
| Typical number | Whatever came up. Rarely memorable | A pattern or a phraseword — 1300 222 222, or something spelling a word on the keypad |
| Up-front cost | Often nothing, or bundled into the plan | A one-off allocation charge, from $250 to $20,000 depending on classification, plus a registration charge |
| Who holds rights of use | Depends entirely on the arrangement, and this is exactly where the ambiguity lives | The registered holder in the numbering system, which should be your business |
| What you should verify | Your contract wording, and whether the number is described as supplied, licensed or leased | That the registered holder is your legal entity, and that you have the rights of use PIN |
Both routes are legitimate. Only one of them is commonly misunderstood
There is nothing wrong with taking a number from a provider's block — most Australian businesses do, and for a number that will never appear on a billboard it is perfectly sensible. The problem is the businesses that spent nine years advertising a number they believed was theirs, having never read the sentence describing it as licensed for the duration of the service.
Rights of Use: The Register That Decides It
The ACMA operates a numbering system, administered on its behalf by ZOAK Pty Ltd, and it is where rights of use are recorded. Three things about it are worth knowing.
The register is the answer
Whoever is recorded as the holder holds the rights. Not whoever advertises the number, not whoever pays the monthly bill, and not whoever believes they own it. If there is a dispute, the register is where it gets resolved.
There is a PIN
Smartnumber holders have a rights of use PIN used to manage and transfer the number in the numbering system. If you hold the rights and have never seen your PIN, you have found something worth chasing today.
Rights can be traded or licensed
Holders may trade smartnumbers, or licence another party to run a service on the number. That flexibility is useful. It is also the mechanism by which a number can end up registered to someone other than the business using it.
Rights lapse if disconnected
You hold rights while the number is connected to a phone service. If it is disconnected, rights continue for three years from the last date of service, after which the number returns to the pool for someone else to buy.
The three-year rule is not a footnote
If you inherited a smartnumber from a business sale, or you are holding one you are not currently using, check whether it is active and when the rights expire. The ACMA is explicit that if someone traded a smartnumber to you, you should check whether the number is active or when it will expire. A number that quietly lapses is not recoverable — it goes back to the pool and anyone can buy it, including a competitor.
What the Government Actually Charges
This is the section that changes how most people read their own invoice, and every figure in it is published.
Smartnumber allocation charges are set by the Telecommunications (Numbering Charges) (Allocation Charge) Determination 2025, and priced by how memorable the number is:
| Classification | Basis | 13 number | 1300 number | 1800 number |
|---|---|---|---|---|
| Platinum | Numeric pattern | $16,000 | $20,000 | $20,000 |
| Diamond | Word value | $8,000 | $8,000 | $8,000 |
| Gold | Numeric pattern | $6,000 | $4,500 | $4,500 |
| Opal | Word value | $2,400 | $1,500 | $1,500 |
| Silver | Numeric pattern | $1,200 | $750 | $750 |
| Standard | Low or no identified pattern or word value | $400 | $250 | $250 |
Those are one-off allocation charges, paid on top of a one-off registration charge, and there are no refunds — so choose carefully. Then there is the ongoing charge, and this is the number worth remembering.

Year of the last smartnumber auction
The ACMA charges telcos an Annual Numbering Charge for the numbers they hold in the numbering system. For 2026 the fee for a ten-digit number is $0.5697110391 — about fifty-seven cents a year. The regulator's rules also state that a telco may pass the fee on to customers, but the fee must match the fee the ACMA sets for that type of number.
Read that against your invoice
A monthly charge for a 1300 number is a perfectly legitimate commercial fee — you are paying for inbound routing, call delivery, configuration and support, all of which cost real money. What it is not is a government fee. If a line on your bill is labelled as a regulatory or ACMA charge and it is more than about fifty-seven cents a year, the label is wrong even if the amount is fair. Ask what it is for. A provider who can explain it has nothing to hide, and one who cannot has told you something.
What Renting Costs, and When It Is Fine
It would be dishonest to write this article as though leasing an inbound number were inherently fraudulent. It is a real commercial model and it suits some businesses. Here is the balanced version.
| Renting is fine when… | Renting is a problem when… |
|---|---|
| The number is a routing convenience that appears nowhere in your marketing | It is on your vehicles, your signage, your invoices and a decade of printed material |
| You are testing a campaign or a new service line and may drop it in six months | It is your brand, to the extent that customers dial it from memory |
| You genuinely understood the arrangement and priced it accordingly | Nobody ever mentioned it, and you have assumed for years that the number was yours |
| You need a premium pattern you could not justify buying outright | You are paying a monthly fee indefinitely for a standard number that costs $250 once |
The specific risks of renting a number you have built a brand on are worth naming plainly, because they are not theoretical:
| Risk | What it looks like in practice |
|---|---|
| The number does not follow you | You leave, the number stays, and every piece of material you have ever printed points at your former provider's customer |
| The goodwill accrues to somebody else | Years of advertising spend build recognition of a number you do not control. That value is transferable, and not to you |
| Pricing leverage runs one way | A renewal negotiation where leaving means rebranding is not a negotiation. It is a notification |
| Rebranding costs land at the worst time | Signage, vehicle wraps, stationery, directory listings, website, Google Business Profile, and every customer who has your old number saved |
The Porting Rules Are Stronger Than You Think
Before this reads as more alarming than it should, the protections are genuinely substantial and most business owners do not know they exist.
Chapter 10 of the Telecommunications Numbering Plan 2025 sets out the porting rules, and the Inbound Number Portability Code covers freephone (1800) and local rate (13 and 1300) numbers specifically. The obligations on a losing telco are unambiguous:
They must port
If another telco asks, at your request, to port out a local, mobile, freephone or local rate number, the losing telco must port the number.
Money owed is not a reason
They cannot refuse or delay porting even if you owe them money. A debt is a debt; it is not a hold over your number. This is the single most useful sentence in the rules.
Do not disconnect first
Only an active service can be ported. The gaining telco is obliged to tell you this, and cancelling your old service before the port completes is the most common self-inflicted disaster in the whole process.
You must be told the costs
The gaining telco must have your permission, warn you about costs such as early termination fees, and give you contract terms. Exit costs are legitimate. Hostage-taking is not.
These rules have teeth, and they have been enforced
It has been reported that in 2021 Telstra paid a penalty of $1.5 million to the ACMA over breaches of number porting requirements, in relation to refusing to port local numbers for customers changing providers. If a provider tells you they will not release your number, that is not the end of the conversation — it is the beginning of a complaint. The Telecommunications Industry Ombudsman is free, and the ACMA is the regulator that sets these rules.
The honest limit of that protection
The porting rules govern moving a service between providers, and they are strong. The rights of use register governs who controls the number itself over the long run, and that is a separate layer. If your contract characterises the number as licensed to you for the term rather than as yours, do not assume the porting rules alone settle the question. Establish who holds the rights, in writing, rather than reasoning from first principles about what ought to be true.
How to Find Out Which One You Have
Twenty minutes, and you will know exactly where you stand. Do it before you need to know, not during a migration.
| Step | What to do | What you are looking for |
|---|---|---|
| 1. Read the contract | Find the original agreement and search for the number itself, plus the words “licence”, “lease”, “supplied” and “rights of use” | Anything describing the number as licensed or supplied for the term. That wording is the whole answer |
| 2. Check for a purchase | Look for an invoice for the number itself — an allocation charge or registration charge, separate from monthly service fees | If you paid $250 or more once, for the number, you probably bought it. If you never paid anything, ask harder |
| 3. Look for a rights of use PIN | Search your records and your email for a rights of use PIN issued when the number was acquired | Having the PIN is a strong indicator that the rights were registered to you |
| 4. Ask your provider in writing | “Who is the registered rights of use holder for this number in the ACMA numbering system?” | A clear, specific answer naming your legal entity. Evasion or a change of subject is itself informative |
| 5. Ask the numbering system | The ACMA publishes contact details for numbering system support: 1300 463 580, or by email | Confirmation independent of your provider. This is the step nobody takes and the only truly authoritative one |
| 6. Write down the answer | Record the holder, the PIN if you have it, and where the documents are | So that the next person in your job does not have to repeat this exercise from scratch |
Fixing It If You Are Renting
If the answer comes back that your provider holds the rights, you have options. They are better if you act while the relationship is still good.
| Option | How it works | When to use it |
|---|---|---|
| Ask them to transfer the rights | Holders may trade smartnumbers. The receiving party must ensure the register is updated, and the ACMA provides a trade of rights of use form for both parties to complete | First move, always. Ask now, while you are a happy customer, not during an exit |
| Negotiate it at renewal | Make transfer of the rights a condition of signing the next term. It costs them very little and it is worth a great deal to you | Your single best moment of leverage in the whole relationship |
| Buy your own and run both | Acquire a smartnumber in your name, point it at the same place, and migrate your marketing to it over twelve months while the old number still rings | If transfer is refused. Slower and cleaner than a hard cutover, and entirely within your control |
| Port the service and sort the rest | The porting rules require the losing telco to port and forbid refusal for money owed. Move the service, then resolve the register position | When you need to leave regardless. Get advice on the register question rather than assuming |
| Complain | The Telecommunications Industry Ombudsman is free. The ACMA sets the porting rules and has enforced them | If a provider refuses a valid port request. Do not accept a flat refusal as the final word |
Buying One Properly From the Start
If you are getting a 1300 for the first time, or replacing one, this is the sequence that leaves you in the strongest position.
Decide how much it matters
Will this number go on a vehicle, a building or a billboard? If yes, buy it properly. If it is a routing convenience, take one from a provider block and stop worrying about it.
Choose the classification honestly
A standard 1300 is $250 once. Platinum is $20,000. A memorable number is genuinely worth money in some businesses and nothing at all in others. Be honest about which you are.
Register it to your legal entity
The company or trustee, not a director personally and not your provider. Get the name exactly right — this is the record that decides everything later.
Keep the PIN and the paperwork
Rights of use PIN, allocation records and the registration confirmation, stored where the business will still find them in eight years when the person who set it up has left.
Then connect it to whoever you like
This is the whole point of doing it in this order. Once the rights are registered to your business, the phone provider becomes a service decision rather than a hostage situation. You can move, negotiate and compare on the merits, because the thing printed on your van comes with you. We are happy to be judged on that basis, and any provider worth using should be.
Seven Clauses Worth Reading Twice
What to look for in any agreement involving an inbound number, before signing.
| Clause | Why it matters |
|---|---|
| 1. How the number is described | “Allocated”, “supplied”, “licensed” and “leased” are not synonyms. If it is licensed for the term, you are renting |
| 2. What happens at termination | Look for anything saying the number reverts, is withdrawn, or is retained by the provider. This is the clause that bites |
| 3. Whether transfer is permitted | Some agreements permit transfer of rights on request. If yours does, exercise it now rather than relying on goodwill later |
| 4. Any fee to release the number | A release or administration fee attached to leaving. Get the amount in writing before you sign, not after you have decided to go |
| 5. Minimum term tied to the number | A number provided free with a three-year commitment is not free. It is financed, and the financing is the term |
| 6. What the monthly number fee covers | Routing and delivery are real costs. A charge described as a government or regulatory fee at more than about 57 cents a year is mislabelled |
| 7. Who is named in the numbering system | The most important item and the one almost never mentioned in a contract at all. Ask, get it in writing, and keep it |
The summary
Nobody owns a phone number; somebody holds the rights of use, and it should be you if the number is on your van. The government's annual charge is about 57 cents, a standard 1300 costs $250 once, and a losing telco must port your number even if you owe them money. Renting is a legitimate product that becomes a problem when nobody discloses it. Spend twenty minutes finding out which one you have, while you still have a choice about it.
