Discord
Discord user lookup
Look up a Discord account by its ID: picture, banner, badges, server tag and when it was made.
Finding someone's ID
In Discord, open User Settings › Advanced and turn on Developer Mode. Then right-click a person, or on a phone press and hold their name, and choose Copy User ID.
What it shows
What Discord shows anyone on a profile card: names, picture, banner, colour, badges and server tag. Discord doesn't share bios, status, connections or servers, so nothing can show those.
Nothing kept
This site doesn't keep a history of accounts or who looked them up, and these pages are hidden from search engines. Discord can't look people up by username, so neither can this.
