Check every handle at once.

Check them together, not one at a time

Checking platforms individually is how people end up with four out of five, and find out about the fifth after the logo is done. A name is only viable if the whole set comes back clean — so we ask the whole set at once.

Some platforms answer, some don’t

YouTube, Reddit, GitHub and Bluesky publish ways to ask, and their answers are dependable. Instagram, X, Facebook and LinkedIn largely don’t, and we won’t log in or work around their protections to force one. Those rows say Unknown and give you the link, which takes a second to settle yourself.

The handle rules that catch people out

• X caps handles at 15 characters. Everything else is looser, so start there.
• Instagram and TikTok allow dots and underscores; X and Twitch don’t allow dots.
• Threads and Instagram share one handle — you can’t take one without the other.
• Discord has no public lookup at all. Nobody can check it for you from outside.
