There are two ways to update the account name shown in your Dashboard:

• Update the account name in Account Settings.
• In the Dashboard, click on the name of your current Stripe account in the upper-left corner, then click Edit.

If you have multiple Stripe accounts, you can only edit the account you're currently viewing in the Dashboard.

Changing your account name will not automatically update your statement descriptor (what your customers see on their bank statements). See What is a Statement Descriptor and how to update it.
