• Add custom thumbnails.

• Appeal Content ID claims.

You may also be asked to verify your account when you sign up.

Why does YouTube ask for my phone number?

YouTube take spam and abuse seriously. Using phone numbers to verify identity is one way to protect our community and combat abuse.

You can have YouTube send a verification code to your phone by entering your number. YouTube also checks to make sure a given phone number is not associated with more than two channels.

I haven’t received the verification code

You should get the code immediately. If you haven’t, you can request a new code. Make sure you’re not running into one of these common problems:

• Some countries/regions and carriers don’t support text messages from Google: Most mobile carriers support text messages from Google. If your carrier doesn’t support text messages from Google, you can try the voice call option, or use a different phone number.
• There are too many accounts with the same phone number: If you get the error message, “This phone number has already created the maximum number of accounts,” you’ll have to use a different number. To help prevent abuse, a phone number can only be associated with 2 accounts per year.
• Text message delivery can be delayed: Delays can happen in densely populated areas, or if your carrier’s infrastructure isn’t well maintained. If you’ve waited more than a few minutes and still haven’t received our text message, try the voice call option.
