Tumblr Username Frequently Asked Questions
How do I check if a Tumblr username is taken?▼
Enter the name into the checker above. We look it up through Tumblr's official blog API — a found blog means taken, a not-found response means available.
What characters can a Tumblr username have?▼
3 to 32 characters using letters (a-z), numbers (0-9), and hyphens (-). Underscores, spaces, and other symbols are not allowed in the blog URL.
Can I change my Tumblr username?▼
Yes — from Settings, and it's free. Your old URL keeps redirecting for a while after the change, then the name is released to anyone.
What's the difference between a Tumblr username and display name?▼
Your username is the URL (name.tumblr.com) and must be unique. Your display name is what appears on your blog header and can be anything.
Do secondary blogs have separate usernames?▼
Yes — each secondary blog has its own URL name that must be unique across Tumblr, which doubles the names worth checking.
Why should I monitor a Tumblr username?▼
Fandom communities, artists, and writers all want clean blog names. Names free up when blogs are deleted or renamed — 24/7 monitoring catches them first.
