Username and ID lookup
Find the permanent numeric ID behind any X username
Every X account has a numeric user ID that never changes, even when the @username does. Developers need it for the X API, and marketers use it to keep tracking an account after a rename. Enter a username to get its ID, or enter an ID to find the profile that owns it today.
Results include a profile card with the name, handle, avatar and follower counts, so you can confirm it's the right account. The ID is returned as an exact string, because X IDs are too long for JavaScript numbers and get rounded by many tools.

How it works
How to convert a Twitter username to an ID
The tool detects which direction you mean.
Confirm the profile
Check the name and avatar on the result card to make sure it's the account you meant.
Copy the ID
Copy it as text and paste it into your code, spreadsheet or API request.
What you get
IDs you can trust in code
Small details that avoid subtle bugs.
Two-way lookup
Username to ID, or ID back to the current username and profile.
String-safe IDs
Long IDs are kept as exact text so they're never rounded.
Profile confirmation
Name, handle, avatar, followers and following shown with every result.
Use cases
Who needs an X user ID
Anyone tracking an account over time or through code.
API developers
Most X API endpoints take user IDs, not usernames.
Tracking renamed accounts
Find an account again after it changes its handle.
Allowlists and blocklists
Store IDs instead of handles so lists don't break when people rename.
Responsible use
Public lookups only
The converter returns public profile information for public accounts. Use IDs to build tools and keep records accurate, not to track or harass individuals. Xholic AI is not affiliated with X Corp.
FAQ
X ID converter FAQ
User IDs, renames and API use.
What is a Twitter user ID?
A unique number X assigns to every account when it's created. Unlike the @username, it never changes.
How do I find my Twitter ID?
Enter your username above and copy the ID from the result.
Does the user ID change when someone changes their username?
No. That's why IDs are the reliable way to track an account across renames.
Can I find an account from its ID?
Yes. Enter the number and the tool shows the profile that currently owns it, if it's still public.
Why do some tools show the wrong ID?
X IDs are larger than JavaScript can store exactly as numbers, so tools that convert them lose the last digits. This converter keeps the ID as a string.
