You can change the username (also referred to as the URL or blog name) for any blog on your account. Blog names can be up to 32 characters long, containing only letters, numbers, and hyphens. However, hyphens cannot be used in the first or last position of a blog name.
Before you proceed, know that changing your URL will break any existing links to your blog that you've made (masterlists/masterposts, links in your description, or any links to your Tumblr you've shared on other platforms). Your followers won’t be affected, and they’ll still see all your stuff come through their dashboard.
If you have trouble saving a name, it may already be taken by another blog. We can't manually release taken or inactive URLs. See this article for more information.
To change your URL on the web:
- Click "Settings" under the account menu at the top of the dashboard.
- Click the blog you’d like to update on the right side of the page.
- Click the pencil icon in the username section (or Tumblr URL section on secondary blogs). Enter your new username.
- Hit “Save.”
To change your URL in the app:
- Tap the account icon (the little human).
- Tap the gear wheel icon.
- Tap "Change name."
- Enter your new name.
- Tap "Save."
