individuals can write down their permanent correspondence address when applying for a trademark, and companies can only apply for a trademark at the registered address of the company, which is the address in the business license. If the company's address changes, it is necessary to change the business license address before changing the trademark. If you apply for a trademark by an agency, other documents of the Trademark Office, such as rejection, rejection, objection, reexamination ruling and registration certificate, are sent to the agency, which has nothing to do with the address you left. Only other documents after successful trademark registration, such as documents that have been put forward by others for three years of non-use, disputes, cancellation, etc., will be sent directly to the address you left. Therefore, if you apply for a trademark in your own name, you should consider the whereabouts of these documents, leave an address where you can receive letters all the year round, or change the trademark address after changing the address.
