Wikipedia:Requests for permissions/Confirmed/Administrator instructions

The confirmed user right provides a user early access to editing privileges that all users receive with autoconfirmed, which is automatically granted when an account has at least 10 edits and is at least 4 days old.

Autoconfirmed or confirmed users can create articles, move pages, edit semi-protected pages, and upload files or upload a new version of an existing file. Autoconfirmed users are no longer required to enter a CAPTCHA for most events and they may save books to the Books namespace. In addition, the Edit filter has a number of warning settings that only affect editors who are not autoconfirmed.

Prerequisites
The vast majority of requests for confirmed are declined. First consider:
 * 1) If they just want to upload an image, they can make a request at Files for upload for non-free images or use the same username and password to upload free images at Wikimedia Commons
 * 2) If they just want to change the name of an article, they can file a requested move

That being said, acceptable means for granting confirmed early may include:
 * 1) The account is a legitimate alternative account of a user who is already autoconfirmed
 * 2) * Check the original account's account creation log to verify the accounts have the same owner
 * 3) * You could also request that the user make an edit under original account confirming the alternate account belongs to them
 * 4) * If the original account does not have an established record in the project, the need for a confirmed alternate account may be questionable
 * 5) The user has been shown especially prolific editing patterns, to the extent that the CAPTCHA's they run into are inhibiting their productivity
 * 6) * The user might have edited under as an IP prior to having the account. For privacy reasons you should not request they verify this
 * 7) * There should be no evidence of unconstructive editing. You may wish to check the user's filter log
