How can I change the registered mobile number?

Welcome to the Community space, @smitagarg.

I’d be glad to guide you on how to change your registered mobile number in QuickBooks Online (QBO). Just a few steps, then we’re good to go. 

If you’re using the QBO mobile app, I recommend logging into your account via a regular web browser and change your mobile number from there. Here’s how:

1. Navigate to your profile logo.
2. Click the Manage your Intuit Account link. 
3. Go to the Sign in & security menu.
4. Select the Phone section. 
5. Click the Change link beside your mobile number.

    

6. Update your mobile number, then click Save.

I’ve also collected these resources that you can read for reference in managing your account information:

• Update billing, payment, and subscription info in QuickBooks Online
• Change the email address your customers see in QuickBooks Online

I’ll be around if you have any other concerns in managing your QBO account. Leave a message below and I’ll answer them for you. Have a great day!
