How do I go about updating my phone number

I do almost all things online first, anything else I do go to the local office if necessary after trying to call in. When you phone in, they have an option to call you back if you can't wait.

Good morning, I have always gone in personally to take care of this matter. The lines have gotten shorter so the wait is tolerable. I went in for a name change with no appointment and was done within 45 minutes.

Lucky you
