It is possible to change an address in person at any post office in the U.S. Making it even easier, the U.S. Postal Service also allows change-of-address forms to be filed online.
Log on to the USPS website
Click on usps.com. Under the "Quick Tools" drop-down menu, choose the "Change of Address" option.
Read the privacy statement
Scan through the privacy statement regarding filing a change of address form. By filing the form, you are making a statement that you are authorized to do so.
Enter the moving information
Check off whether the change of address is permanent or temporary, and indicate the type of move occurring. Choose the change of address date.
Enter contact information
Enter new and old address information into the provided spaces. Include the requested contact information.
Confirm your identity
Enter credit card information to confirm that your identity matches the address being changed. Your card will be charged a small amount ($1.05 as of 2014) to confirm the information posted. This step provides security against people changing other people's addresses maliciously or as a prank. The final step is to confirm the change of address order.
