Bluesky handle questions
What are Bluesky handle rules?
Bluesky handles must be 3 to 18 characters long and can contain letters (a to z), numbers (0 to 9), hyphens (-), and underscores (_). Handles cannot start or end with a hyphen. Periods and spaces are not allowed in the basic handle format.
How does a Bluesky handle work?
On Bluesky, your handle appears as @yourhandle.bsky.social, for example @alice.bsky.social. The full handle includes the .bsky.social domain suffix. This tool validates the part before .bsky.social.
Can I use a custom domain as my Bluesky handle?
Yes. Bluesky supports custom domain handles like @yourname.com. This is one of Bluesky's unique features. This tool validates the default .bsky.social handle format; custom domain handles follow different rules.
Can I change my Bluesky handle?
Yes, you can change your Bluesky handle at any time from Settings → Change handle. If you previously used a .bsky.social handle, it becomes available for others after you change it.
Why does this tool say 'appears available'?
Postlia validates your handle against Bluesky's format rules (length, allowed characters, and structure), and then does a live check against the Bluesky API to see whether the handle is already registered. If the live check is inconclusive (Bluesky is unreachable or rate-limited), we say so and link you to bsky.app to confirm.
Can I use hyphens in a Bluesky handle?
Yes, hyphens (-) are allowed in Bluesky handles, but you cannot start or end with a hyphen. For example, @my-brand is valid, but @-brand or @brand- are not.
