Global Entry address change

Global Entry address change I am a member of Global Entry and have moved to a new residence. It appears that one's mailing address can be changed online, but changing residential address requires visiting an Enrollment Center in person. According to https://ttp.cbp.dhs.gov/faq?lang=en: I am enrolled in a Trusted Traveler Program. Do I have to notify you if I change my address? Yes. If the mailing address that you originally submitted for the Global Entry/NEXUS/SENTRI/FAST program has changed, you can login to the TTP website to update it. On the right hand side of the Dashboard you will see a link to update your mail-to address. You will need to go to the nearest Enrollment Center to update your current address (where you live). General information for Enrollment Centers can be found here: [links] Questions: Is it necessary to make an appointment at the Enrollment Center, or can one walk in during its posted hours? (Elsewhere on the page above, under "I have had something significant change about my information", it says no appointment is needed.) What documents does one need to bring? Does one have a specific amount of time after the move (e.g. 30 days or something) to make this visit?
