Wikipedia:Changing username

Before requesting a username change (rename), please read through the Must Read section to know the limitations and alternatives.

If the username change is simple and you have a confirmed email address, use Global user account rename request. For other cases, use the appropriate request page listed below.

Usernames are global,[lower-alpha 1] and are the same on all Wikimedia projects―Wikipedia, Wikimedia Commons, etc. Requests to change a username are processed by users enabled to do so (global renamers and stewards) in accordance with the global rename policy.

Requests for usernames which are offensive, promotional, disruptive, misleading, or confusing are not accepted.
