Can you help me to change the telephone number in our accountant Quickbooks?

Hi clara-kodyafrica We'd be grateful if you can login to accounts.intuit.com using the same login details that you login to your account with and you'll be able to amend your telephone number. If you're not able to login as the MFA code is being sent to the number and you don't have access to it please complete and submit the from contained within the link below. Please enter your email address associated with your QuickBooks account in the old and new email address fields, the user ID is what you sign in to your account with, usually the same as your email address, unless you've changed it and enter your mobile number in the phone number field. Once submitted the form will take approximately 3-4 hours to be processed.
