Where can someone find a template for a letter to notify of a company's change of address?

An "address change notification letter" template is available at the Microsoft Office website. Letters of this sort, which are intended to notify relevant parties, such as business contacts, of a company's address change.

These change of address letters should include the sender's name and address, the recipient's name and address and a salutation before an introduction to the purpose of the letter. This should then be followed by a reminder of the company's previous address and a notification of the new address. Companies with an established online presence might also opt for posting a copy of the letter to their website, in order to reach a wider audience.
