# How can I change my account id/username?

It is not possible to [change an account's ID](https://docs.mapbox.com/accounts/ja/guides/settings/#change-an-accounts-username-not-possible) (username). But you can [add or change the account's organization name,](https://docs.mapbox.com/accounts/ja/guides/settings/#change-an-account-holders-name) which will populate on all invoices.

Or, you can create a new account, [transfer your map styles,](https://docs.mapbox.com/help/troubleshooting/transfer-styles-between-accounts/) and update your web and mobile applications to reference the new account's tokens and styles. For more information about setting up an account for a team or preparing for an ownership transition, see [our guide for collaboration](https://docs.mapbox.com/help/troubleshooting/collaboration-best-practices/#best-practices-for-setting-up-an-account).
