609.02(d) Changing the Correspondence Address in Multiple Applications or Registrations 
The TEAS change of correspondence address form can be used to change the correspondence address for more than one application or registration. An applicant or registrant may submit up to 300 application serial numbers at one time. For registered marks, the TEAS form requires entry of the original application serial number rather than the registration number. Requests to change the address for more than 300 applications/registrations cannot be submitted in a single TEAS form.
Global address updates (i.e., requests to change an address in every application or registration in which it appears) will not be accepted.
