You click Link Medicare, MyGov says a security code has been sent, and nothing arrives. You wait. You retry. Still nothing. Meanwhile, your Medicare rebates, digital health records, and online claims remain locked behind a step you cannot complete.
This problem can affect many Medicare users, and for expats or Australians living abroad, it may create even more friction.
In many cases, the issue is fixable. The code itself may not be the real problem. What often breaks is the path between Services Australia’s system and the phone number tied to your records.
What the linking process checks
Before sending any SMS code, Services Australia may verify that the details you enter match the information already stored in your Medicare record.
That usually includes your full name as it appears on your Medicare card, your date of birth, your Medicare card number and reference number, and the phone number connected to the record.
If one of those details does not line up, the process may stop before the SMS is delivered. Many users assume the issue starts with their device or carrier. In practice, the problem may sit earlier in the verification chain.
Why security codes fail to arrive
Code delivery problems usually come from one of a few common causes. The most frequent ones are account mismatches, outdated contact details, or phone setup issues.
| Category | What happens | Who it may affect most |
|---|---|---|
| Account mismatch | Name, date of birth, or card details do not match Medicare records exactly | People who changed names, updated cards, or have inconsistent records |
| Outdated phone number | The SMS goes to a number you no longer use | People who changed carriers, lost a SIM, or moved overseas |
| International number | Delivery to non Australian numbers may be less reliable | Expats, travellers, remote workers |
| Temporary or prepaid SIM | The number may expire or become inactive before the code arrives | Users with short term SIMs or pay as you go plans |
Many users fall into one or two of these categories. The right fix depends on identifying which one applies in your case.
What to check before trying again
Before trying again, work through these checks in order:
• Confirm the phone number on file with Medicare by calling Services Australia or checking through any service you can still access
• Check that your name matches exactly between your Medicare card and your MyGov account
• Verify that your Medicare card is current and has not been replaced
• Wait at least 30 minutes between attempts so you do not run into a temporary lockout
• Check your SMS inbox and message filters in case government messages are being screened
• Make sure your number is still active by sending yourself a test message first
If you live outside Australia and your Australian SIM has expired or been deactivated, the code may have nowhere reliable to land. For expats, that can be a common roadblock.
How contact setup affects long term access
MyGov may use SMS verification not only during the initial linking process, but also for account recovery, session checks, and other identity steps later on. Medicare may also send claim updates or notifications to the number linked to your account.
Losing access to that number can affect much more than one login attempt.
| Setup | Code delivery reliability | Works from overseas | Long term stability |
|---|---|---|---|
| Active Australian postpaid SIM in Australia | High | Usually not unless roaming is active | High |
| Australian prepaid SIM kept active | Medium to high | Depends on roaming setup | Medium |
| Australian virtual number with SMS support | High | Yes | High, depending on provider stability |
| Foreign mobile number | Lower | Yes | Less consistent with some Australian verification flows |
For expats and Australians living abroad, one practical pattern shows up often: keeping a stable Australian number active can remove one of the main points of failure in the verification flow.
For users living abroad, one practical option is keeping an Australian number active without depending on a physical SIM.
Services like VNumber can help maintain that continuity by supporting ongoing SMS access while you are outside Australia. That can make it easier to keep your Medicare and MyGov contact details consistent over time.
If you need a stable Australian number for verification, account continuity, and ongoing access to digital government services, get your number with VNumber and keep your access active wherever you are:

If you are locked out right now
If codes still are not arriving after several attempts, it may be better to stop retrying and deal with the contact issue directly first.
Call Services Australia at 132 011 from within Australia or +61 2 6124 8824 from overseas. An agent may be able to verify your identity, review your contact details, and in some cases help you move the process forward.
You can also visit a Services Australia service centre in person with photo ID and your Medicare card. That may help in situations where SMS based verification is not working.
Once your account is linked and your contact details are current, future interactions with Medicare through MyGov may become much easier. That includes claims, statements, safety net tracking, and access to digital health records.
Frequently Asked Questions
Do I need an Australian phone number to link Medicare to MyGov?
Services Australia does not publicly frame an Australian number as a universal requirement for every interaction. Even so, SMS delivery to international numbers may be less reliable, and the phone number on your Medicare record usually needs to align with the one receiving the code. In practice, an active Australian number can improve the chances of smooth delivery.
Can I fix this issue while living outside Australia?
Yes. You can contact Services Australia from overseas, review or update your phone number, and try the linking process again. If you have access to a stable Australian number that can receive SMS, that may help reduce friction.
What if my Medicare card has been replaced and I am using the old number?
A replacement Medicare card may come with a new reference number. If you are entering details from an older card, the system may not find a match. It is best to use the most recent card issued to you.
How many times can I try before getting locked out?
Services Australia does not publish a fixed number. Multiple failed attempts within a short period may trigger a temporary lockout, so waiting before trying again is usually safer than repeating the same attempt immediately.
