Invalid Mobile Number for Customers

Minifarmp_11 — Sun, 21 Sep 2025 08:06:38 GMT

Does anyone know why Australian Mobile numbers are invalid for customers when placing an order.

I checked my own and it was invalid also. I selected +61 Australian then entered my mobile and was rejected.

Thanks Square for loosing us customers, great job with your site.

Hi Arie,

Thank you our store is - http://minifarmbox.com.au/

In the end section where customers add their details before check out it has the issue with phone numbers.

I tried it on Brave and it did not work then I tried it on my mobile and it did work. The customer that complained did not say what browser they used.

Regards,

Nick

Hi Arie,

Did this get resolved? I have just had the same issue reported but I have a theory that it is private or incognito mode that is the issue. I can process as normal on chrome or edge but if I go to incognito mode it requires me to enter the phone number without the 0 at the start of the mobile number.

Can you give it a try and confirm/deny this could be the problem.

Cheers
