# TweeterID
Tool Description : A simple X/Twitter username and ID conversion tool.
| **TweeterID** | **Quick Overview** |
| ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| URL | |
| What it does | Converts X/Twitter usernames and account IDs between the two formats. |
| How to use it | Simply enter an X/Twitter @handle or account ID and select Convert, then review results. |
| Cost | Free. |
| Account required | No. |
| Cookies | Mostly Google advertising/measurement cookies plus Google Analytics |
| Ownership | Not clearly disclosed. |
| Use in Reporting | Useful for documenting and identifying X/Twitter accounts by their persistent account ID and for linking an account ID to its current or associated username. |
### What does TweeterID do?
TweeterID simply converts between an X/Twitter account's unique ID and its publicly visible username/@handle. X/Twitter IDs are unique to individual accounts and, unlike usernames, do not change when an account changes its handle.
**The lowdown:** It's a lightweight identity-resolution and account-verification utility for X/Twitter, particularly useful when you need to establish the relationship between a username and its underlying account ID.
### How to Use:
**1. Copy the X/Twitter @handle or account ID you want to investigate and enter it into the TweeterID converter.**
**2. Record the returned ID or username and cross-reference it with other sources before drawing conclusions.**

## Data Processing
### Account Required:
* [ ] Yes
* [x] No
### Cookies:
The site uses Google Analytics cookies (\_ga and \_ga\_\*) for visitor/session measurement and Google advertising-related cookies such as \_\_eoi.
### Use in Reporting
TweeterID can be used to:
* Help establish continuity when an account's username has changed.
* Record a more persistent identifier for an X/Twitter account.
* Support identity resolution when investigating social-media accounts.
* Cross-reference an account ID with other X/Twitter evidence.
* Provide a reproducible identifier when documenting an account in an investigation.
* Support verification of whether different usernames relate to the same underlying X/Twitter account.
**Reporting Caveat:** The platform should be used alongside screenshots, archived material, and other independent evidence rather than treated as proof of the account holder's real-world identity.
| Capabilities | Limitations |
| ----------------------------------------------- | ------------------------------------------------------------------------------------------------ |
| Converts X/Twitter handles to account IDs. | Does not establish the real-world identity of an account holder. |
| Converts account IDs back to usernames. | Depends on the availability/recognition of the relevant X/Twitter account information. |
| Provides a persistent account identifier. | An account ID alone provides little contextual information. |
| Useful for documenting social-media accounts. | Does not independently verify that an account is authentic or controlled by a particular person. |
| Can support account-change/continuity research. |
|
### Summary
TweeterID is a simple, free X/Twitter account-ID conversion tool that best fits in the verification/identification stage of the OSINT workflow. Its main value is that an account ID is more persistent than an X/Twitter username, which can change over time.
### Ownership
Not clearly disclosed. Historical website metadata identifies Jared Feldman and Dillon Hess as the authors of TweeterID, while domain-registration records have used privacy protection.
### Ethical Considerations
* Treat an account ID as an identifier, not proof of a person's real-world identity.
* Be aware that usernames can change and avoid assuming that a historical username necessarily represents the same person without corroboration.
* Cross-check important findings using independent sources.
* Avoid unnecessarily collecting or publishing personal information.
* Preserve relevant evidence, including the date and time an account/handle was observed.
* Clearly distinguish between an X/Twitter account identity and the identity of the person operating the account.
