Sender ID Registration Information
From 1 July 2026, businesses and organisations that send branded SMS messages using a Sender ID will need to have that Sender ID registered. If a Sender ID is not registered, messages sent with that Sender ID will be labelled “Unverified”. Summit One is making this information available to help clients understand the changes and prepare to apply through our platform.

–Sending text messages with your business or organisation name
Why this is important
The register has been introduced to reduce impersonation and scam messaging. From 1 July 2026, if your Sender ID is not registered, your text messages may be labelled “Unverified” and grouped with other unverified messages, including scam messages, on recipients’
phones. ACMA also recommends applying as early as possible and not waiting until June, because late applications may not be approved in time.
Registering your Sender ID helps customers recognise that messages from your organisation are genuine. It also makes it harder for scammers to impersonate your organisation and reduces the risk of confusion, reputational damage and disruption to your customer
communications.
Sender ID Registration Information
What is a Sender ID?
A Sender ID is the branded name that appears at the top of a text message instead of a phone number. It tells the recipient who the message is from. For example, a business, club or organisation name. not properly registered can show as “Unverified”.
Sender ID guidelines
Your Sender ID must meet ACMA’s validation rules before it can be registered. In general, a Sender ID must:
- be 2 to 11 characters long
- use standard characters only
- not consist only of numbers
- not start or end with a space or underscore
- not contain the word “Unverified”
- not be offensive, deceptive or misleading
- have a valid use case, meaning it must clearly match and be linked to your
organisation.
For organisations with an ABN, your Sender ID should match or clearly relate to one of the following:
- your registered business name
- your company name linked to an active ABN
- your registered trade mark
- your registered domain name, where that domain is linked to a legitimate website or active email address.
A Sender ID may be the same as your organisation name, a shortened version, an acronym, an abbreviation or an initialism. It may also include extra words connected with your organisation’s function, location or the purpose of the message, provided it still clearly identifies your organisation.
What is not permitted?
Sender IDs will not be accepted if they are offensive, deceptive, misleading, made up only of numbers, contain “Unverified”, or do not have a valid use case. A Sender ID also cannot consist solely of a restricted word published by ACMA. Restricted words include examples such as account, alert, bank, bill, delivery, info, message, notice, service, support, urgent, verify and verified. Restricted words may only be used when combined with other characters that clearly identify your organisation, such as “ACMA Alert”.
What to do before applying through Summit One
1. Review the Sender ID you want to register
Before applying, make sure the Sender ID you want to use meets the rules above and is clearly linked to your organisation. Useful checks include:
- ABN Lookup for your ABN and business name
- IP Australia Trade Mark Search for registered trade marks
- auDA WHOIS for your domain name registration.
2. Confirm your authorised contacts are up to date on the ABR
To access the register after Summit One applies on your behalf, your organisation must either have the relevant person listed as an authorised contact on the ABR, or that person must be approved by an authorised contact on the ABR. If your authorised contacts are not up to date, you may not be able to access the register. You can check your business details via ABN Lookup and update your details through the ATO and ABR process.
3. Nominate the right Authorised Representative
Before you apply through Summit One, decide who your organisation’s Authorised Representative will be. For Summit One applications, the best choice is usually a person already listed as an authorised contact on the ABR who works as an office holder within the business. That person should also have access to their business email address and mobile number so they can complete the authorisation steps promptly. Under the register rules, the person making the request must be listed as an authorised contact on the ABR or otherwise authorised by the entity, must pass an identification check and must agree to the register’s terms of use.
4. Set up a myID Digital ID
Your Authorised Representative will need to prove their identity using the Australian Government’s myID app when logging in to ACMA Assist to view, confirm or revoke Sender IDs for your organisation. Please set this up before you apply if possible.
5. Tell us if you are applying for multiple venues, brands or on behalf of another entity
If you operate multiple venues or brands, the cleanest approach is usually to register the Sender ID that matches the specific venue or entity that owns and uses it. If one entity is acting on behalf of another, or if you are using a Sender ID owned by another business, extra authorisation steps may apply. Summit One may need confirmation from the Sender ID owner before the application can proceed.
How to apply for a Sender ID through Summit One
Step 1: Nominate your clubs’ Authorised Representative
1. Log into your Summit One account
2. Find your admin settings: admin > accounts > edit (icon)
3. Enter the details of your nominated Authorised Representative
a. Full name
b. Mobile
c. Email (preferably linked to your registered domain)
4. Advise the nominee of the below.
Step 2: Verify the ACMA’s registration.
You, or your nominated Authorised Representative will shortly after receive instructions from the ACMA via email on how to complete the registration. If you yourself are not listed as an authorised contact for the club on the Australian Business Register, you may still receive instructions from the ACMA via email on how to complete the registration. If so, you need to forward the email to the clubs’ Authorised Representative
nominated in Step 1.
The ACMA requires your nominated Authorised Representative during this process to:
1. Create an ACMA Assist account (if not already done before)
2. Verify their identity using MyID
3. Make sure the contact details in the register are up to date so you can get updates
about your registration.
Note: The ACMA now requires your myID identity strength to be Standard or higher. If you have a
Basic identity strength (with no document check), you will need to open your myID app and upgrade
to Standard. If you have already verified at Standard or higher, no action is required.
Visit myID.gov.au for more information on upgrading your identity strength.
Once logged in, simply:
- select your sender ID(s), and
- select “Confirm registration of Sender ID application”. That’s it.
Step 3: Await confirmation from Summit One
No more action will be required on your end.
Once your registration has been approved by the ACMA, they will notify Summit One and your nominated Authorised Representative. This may take several days.
Once we receive approval from the ACMA, your sender ID will be processed in Summit One.
Both yourself and your nominated Authorised Representative (if not one and the same) will then be notified by Summit One that your sender ID has been processed and ready to start sending.
If you have already registered a Sender ID with the ACMA
If you have already registered your sender ID with the ACMA, you can use it with Summit One without going through the aforementioned process. Please contact your account manager if this applies to you.
Likewise, registering your Sender ID through Summit One does not limit your sender ID usage to the Summit One platform. You are able to use your sender ID with any Australian supplier.
Costs and fees
Any Summit One fees for assisting with a Sender ID application will be disclosed before you proceed. ACMA also notes that there may be fees in future for using the register, and any such fees would be communicated before implementation.
FAQ
About the changes
Why is this changing?
The ACMA is bringing in a central Sender ID Register to help stop scam texts and make branded SMS more trustworthy. From 1 July 2026, Sender IDs that are not properly registered can show as “Unverified”.
What is a Sender ID?
It’s the name that appears at the top of a text message instead of a mobile number — for example, your club name.
Wasn’t this already done last year?
Partly. Last year, the ACMA implemented changes which required us to register sender ID’s with our telecommunication suppliers. This was always a precursor to a centralised registration register, which we are seeing now. Last year’s measures simply verified the basic requirements to match an ID to a business name defined by s 4(2) under section 484F of the Telecommunications Act 1997 (Cth) (Act). This is why current Summit One clients are only required to undergo half the process now required to register a sender ID.
What your club needs to do
What do we need to do now?
The main thing is to work out who your club’s authorised representative should be. That person should already be listed on your club’s ABR. Once the Summit One admin update is live, you’ll nominate them in your account and we’ll guide you through the rest.
Who should be our authorised representative?
Usually this should be someone already listed on the ABR who can approve things on behalf of the club — for example, a director, secretary, public officer or another appropriate authorised contact.
Does the authorised representative need to be on the ABR?
Yes. Only authorised representatives listed on your clubs’ ABR will be granted access to
ACMA Assist to verify sender IDs.
Will they need to verify their identity?
Yes. The authorised representative will need to complete an online identity and authority check, usually through myID and ACMA Assist.
What details should we have ready?
It helps to have the following ready before you start:
your club’s legal or trading name
- your ABN
- the Sender ID or Sender IDs you want to use
- the authorised representative’s full name
- their mobile number
- their business email address (preferred)
- your website or domain if relevant
Using Sender IDs in Summit One
Can Summit One help us register a Sender ID?
Absolutely. If your Sender ID is not already registered, we can guide you through the process from your admin panel or O you can contact your account manager to help you out.
We facilitate the process and it is relatively straight forward.
Is Summit One certified to register Sender IDs?
For all Australian clubs with an ABN, the normal message-provider process applies. A separate “certified” pathway is mainly relevant for organisations without an ABN.
What if our Sender ID is already registered?
That’s fine. You can still use it with Summit One. Just let your account manager know so we can link things up properly.
Does registering through Summit One lock us into Summit One?
No. Registering your Sender ID through Summit One does not limit your Sender ID usage to the Summit One platform. You can use the same Sender ID with other Australian suppliers, as long as they are authorised to use it.
Can we send SMS without a registered Sender ID?
That would be impossible. All sender IDs are checked against the Register before and after making your sender ID available for use in Summit One.
Can we use Summit One if we do not have an ABN?
Summit One does not permit the transmission of SMS from any company not registered on the Australian Business Register. Registration requests from outside of Australia, or from
generic email domains will not be considered.
Sender ID rules
Are there limits on what we can register as a Sender ID?
Yes. Your Sender ID must clearly relate to your club, business, brand, domain name or trade mark. It can be the full name, a shortened version, an acronym or an abbreviation, but it still needs to clearly identify you. It also has to follow ACMA’s formatting rules. For example, it must be 2 to 11 characters long, cannot be numbers only, cannot start or end with a space or underscore, and cannot include the word “Unverified”. Misleading, deceptive or unrelated Sender IDs are not allowed.
What makes a good Sender ID?
Keep it clearly linked to your organisation. A club name, shortened club name or well- known brand name usually works best.
What is not allowed?
A Sender ID can’t be misleading, deceptive or unrelated to your organisation. It also can’t be numbers only, can’t include the word “Unverified”, and can’t be made up only of restricted generic words like “Alert” or “Support”.
Can we register more than one Sender ID?
Usually yes, as long as each one has a valid business reason and clearly links back to your organisation.
We have more than one venue or brand. Do we need separate Sender IDs?
Yes. If you use different brand names or venue names in your messaging, separate Sender IDs can make things clearer and easier to approve. If you’re unsure, ask us before
submitting.
What happens next
What happens after we nominate our authorised representative?
We’ll handle the provider side of the process and your authorised representative will receive instructions to confirm the Sender ID online. Once approval is complete, we’ll let you know when the Sender ID is ready to use.
What happens if we ignore the emails about this?
Please don’t. These emails guide the person who needs to approve your Sender ID. If they aren’t actioned, your Sender ID can be delayed and your messages may not work the way you expect.
Who can I speak with if I need more help?
You can call us on 02 8015 6538 during office hours, email support@summitone.com.au, or contact your account manager directly.
