Frequently asked questions

Why do I need a Twitter numeric user ID?

The numeric ID is the stable identifier used by the Twitter API, ads custom audiences and most data pipelines. Unlike the @username, it never changes, so it is the safe key to store.

Does the user ID change if the account renames itself?

No. The numeric ID is assigned at account creation and stays the same forever, even if the @handle or display name changes.

Can I convert a user ID back to a username?

Yes — the xAPIs batch user endpoint accepts numeric IDs and returns full profiles. This page converts username → ID; the API covers both directions.

Is this tool free?

Yes, up to 10 lookups per day per visitor. For bulk ID resolution, the xAPIs API resolves batches of IDs in a single call.
