Aggregating addresses by subdivision while keeping owner name intact

[Skarlett_One]

I have a list of just over 6,200 names and addresses that I need to separate into their respective community subdivision, but I need to keep the owners names with those addresses. This is in order to add postal/zip codes and cities to the addresses. Is there a way to do this? For example, I need to have all the addresses on "Thompson Street SE" together, but with the names of the homeowners attached to those kept intact.
