What are some overlooked people/organizations to inform when changing address?

Question

I'm making check-list for organizations to inform when changing address like taxes; bank; bills like phone, internet, power, what else ..

Answer 1

Try going to www.usps.com, that's the US Postal Service's web site.  They have a link for change of address, and I think they have suggestions on who to inform there.  My suggestion would be any charities you deal with, or alumni associations.
