The Move Update standard currently applies to mailings of First-Class Mail. Effective November 23, 2008, the minimum frequency for Move Update will change from 185 days to 95 days prior to the date of mailing and the Move Update standard will also be required for all Standard Mail. In order to comply with the Move Update standard, mailers must update an address used on a mailpiece in a mailing for any class of mail with an approved method.  Customers can also meet the Move Update standard if the same address is used in a First-Class Mail or Standard Mail mailing within 95 days after the address has been updated. Except for mail bearing an alternative address format, addresses used on all pieces claiming Standard Mail rates will be required to meet the Move Update standard.

See Quick Service Guide 230a for an overview of the Move Update standards.
