Bluesky handle questions
- What are Bluesky handle rules?
- Bluesky handles must be 3–18 characters long and can contain letters (a–z), numbers (0–9), 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 only. We cannot check real-time availability — only Bluesky knows which handles are registered. After validating here, open bsky.app and search for the handle to confirm it's free.
- 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.
