Filling out your Change of Address Forms is quick and only takes a minute at USPS.com. You’ll need to know your old address, the new address and which date you’d like the mail to start forwarding.
For specific information, such as different people moving to different households or moving a business to a household, this Movers FAQ guide from the Postal Service will help.
Not all post offices will forward government checks, so be sure to notify the IRS of your address change. Note that it can take four to six weeks for the change of address to be fully processed.
To protect yourself and your personal information, you should also notify your financial institutions, credit card companies and medical providers.
