How can I delete assigned number to an account created as secondary account while I need to use same email as it is company email

I see that you want to delete the assigned number from your secondary account since you need to use the same email. Don't worry, Azaki. I'll provide more insights and lay down the steps for you. Rest assured that after performing them, you'll be able to get back to business promptly.

In QuickBooks Online (QBO), providing a phone number during account setup is essential. This serves as a crucial element for verification and security measures. While it's required and cannot be deleted, you have the option to update it to another active number. Here's how:

1. Sign in to your QBO account.
2. Click your Profile icon and select Manage your Intuit Account.
   
   
   
   
3. Tap the Sign-in & Security tab.
   
4. Go to the Phone section and make the necessary changes.
   
5. Hit Save.
   
    

   

   
   
   

Additionally, the information your customers see on their sales forms depends on what you set up in your account. To edit your contact information, here's how:

1. Click the Gear icon and choose Accounts and Settings.
   
   
   
   
2. Tap the Company tab, then select the pencil icon beside the Contact info area.
   
   
   
   
3. From the Company Phone dropdown, type in the number you wish to appear on your sales forms.
4. If you don't have anything else to change, hit Save, then Done.
   
   
   

The instructions I've given above should help you edit the assigned number in your secondary account, Azaki. If you happen to come across any difficulties while navigating QBO, just let me know. I'll always be here to provide guidance and support.
