When an individual or a business moves, it can be a challenge to find the new mailing address. Services like FedEx charge a fee for obtaining a corrected forwarding address. But you can often find a forwarding address without paying a fee.
Obtaining a Forwarding Address
Send mail to the old mailing address. On the letter or package, write "Address Correction Requested." This will alert the post office to send you notification of the new address in addition to forwarding the piece of mail. If the mail is returned, the forwarding address should be included on a sticker that is placed on the returned letter or package.
Contact a relative or friend of the person who has moved. If you're on good terms with the person, a relative or friend will often provide the person's new address. Or he will offer to forward the letter or package on your behalf along with a request for the person to get in touch with you.
Contact the alumni office for the person who has moved. If you also went to the same school, the alumni office might forward a message to the person asking him to get in touch with you. If you didn't attend the same school, that is less likely. But it's not impossible to persuade the alumni office to forward a message on your behalf.
