Hello info303
The phone numbers within Australia usually have 10 digits: 2 for the area code and 8 for the user's number. Let's say your phone number is 0412345678.
To write it in international format, you only need to remove the zero (0) from the beginning and add +61. This should how your number looks like: +61412345678.
You can enter either of these phone number formats in QuickBooks Online. You just need to remove the special character (+) and the spaces between the numbers.
- Click the Gear icon in the upper-right corner and select Account and Settings.
- Select the Company tab and go to the Contact information section.
- Enter the numbers in the Company phone field.
- Click Save and Done.

Another way of entering the phone numbers is through the Custom Form Styles. Here's how:
- Click the Gear icon in the upper-right corner and select Custom Form Styles.
- Look for the Standard Master template and click Edit.
- Go to the Content tab and select the first section.
- Under Header, mark the Phone box and enter the phone number.
- Click Done.
