Trying to subscribe to quickbooks payroll and says my mobile phone number is not valid business phone number. What am I doing wrong?

Let me help you bypass the error you've encountered in QBO, Davies.

The error you're seeing when entering your business phone number is due to an incorrect number format.

To get this issue resolved, you'll have to ensure the number you've entered is formatted correctly for your region. Using the correct format is essential to prevent system issues.
