Hello there, elizabeth31,
There's a need to call support to change support in changing the contact information. Especially if you no longer have access to the old phone number.
Did you receive an error while trying to get in touch? Let's use the QuickBooks Online test drive and contact support from there.
Here's how:
- Go to the Help icon.
- Select Talk to a human.
- Enter "Talk to a human" again in the search bar.
- Choose I still need a human, then click Contact us.
- Select Get a callback or Send a message to start a conversation.
I'll add this article as your reference on how to update company information: Change your business name, contact info, or EIN in QuickBooks Online.
If you have other concerns, let me know by leaving a reply below.
