Since the account verification requires a code from the phone number, and you entered your phone number incorrectly. I suggest reaching out to our customer support team. They will need you to send a request to our account protection team. You must fill out a form and attach proof of identity (valid ID) to recover your account within one business day.

2. Press the Search tab, then select Contact Us.
3. Enter your concerns and click Continue.
4. Select either Chat with us or Have us call you. 

I've also attached an article you can use to update your business info or customer email address in QuickBooks Online: Update or change your Intuit Account sign-in information.

I had a number on my account i no longer have anymore but each time i try to update my new number it keep asking for a verification code but i can’t get the verification code. 

Let me share ways to update your phone number in your QuickBooks Online (QBO) account, Scaine20.

If you don't have your old number to receive the verification code, let's utilize your email address affiliated with your QBO account. Kindly follow the steps provided below.

1. Go to our sign-in help page.
2. Enter your email address or user ID for your account.
3. Type in your email address in the designated field. Once you have entered your email address, you will receive a verification code via email.
4. Enter the verification code we sent, or follow the instructions in the message. We Would ask for some more information to ensure it's you.
5. When prompted, reset your password. Or, you can select Skip.

Furthermore, I suggest contacting our customer support team if you can't access both your email address and phone number associated with your account. They will guide you through sending a request to our account protection team. To recover your account within one business day, fill out a form and attach a valid ID as proof of identity through this link.

Keep me posted if you need additional help acquiring your verification code in QBO. I’ll jump right back in to assist further. Have a great day ahead, Scaine20.
