Thank you for sharing your concern in the QuickBooks Community, @Paris72.
There might be something that went wrong during the installation of QuickBooks on your computer. This can be the reason why you're getting an error message that you're phone number is invalid.
To clear out the issue, let's run the QuickBooks Install Diagnostic Tool. This can help us verify and fix some minor install issues in QuickBooks Desktop (QBDT).
Here's how:
- Open the QuickBooks Tool Hub, then select Installation Issues.
- Click QuickBooks Install Diagnostic Tool. Let the tool run. It can take up to 20 minutes.
- When the tool finishes, restart your computer and start QuickBooks Desktop, then open your data file and try to activate it again.
If the solutions above didn't fix the problem, perform a clean install of QuickBooks. Doing this action, won't affect your company data file and everything it holds.
If the issue persists, I'd recommend reaching out to our phone specialist. This way, they can verify your phone number and help you in activating QuickBooks.
