Nothing you paste here is stored. IDs are 17 to 20 digits; usernames are not accepted because Discord has no public username lookup.

How to find a Discord user ID

  1. Open Discord and go to Settings, Advanced, then turn on Developer Mode.
  2. Right-click a username anywhere (or tap and hold on mobile) and choose Copy User ID.
  3. Paste it above. Server IDs and message IDs are the same kind of number, so the creation date works for those too.

What the lookup can and cannot tell you

A Discord ID is a snowflake: 64 bits, the first 42 of which are the number of milliseconds since 1 January 2015. That is why the creation date can be read from the number itself, offline, with no API call. The rest of the number identifies the machine that issued it and a counter. There is no name, email, IP or location inside it, and Discord does not provide those through any other route either.

Username, display name and avatar are live profile fields that need a Discord API request. When this tool is connected to the API it shows them below the creation date; otherwise it shows the dates alone.

Why account age is the useful part

Operators look up accounts for one reason: to tell real members from throwaway ones. An account created the same week it joined your server, with a default avatar, is a bot or a raid account most of the time. Checking one at a time is fine for a suspicious DM. For a whole server, export the member list with WiseCord: the creation date and the join date are both columns, so sorting by either shows you the pattern in seconds. See the Discord member list page for how that works, and the Discord tracker page for watching new joins as they happen.

Turn on Developer Mode in Discord under Settings, Advanced. Then right-click any username, or tap and hold on mobile, and choose Copy User ID. The ID is a 17 to 20 digit number.

The ID is a snowflake: a number that encodes the exact time the account was created. From it you get the creation date and the account age. With Discord API access you can also fetch the current username, display name and avatar. Nothing else is stored in the ID.

No. Discord does not expose any of those to other users or to any tool. Sites that claim to are scams or malware. This lookup never asks for or shows that data.

Usernames change and are not unique across time, so there is no reliable public username-to-profile lookup. Search for the person inside a server you share, copy their ID, and look that up instead.

A server full of accounts created last week is a server being botted or raided. When you export a member list with WiseCord the creation date is a column, so you can sort real members from throwaway accounts in one pass.
