My wife and my passport expired during the pandemic. Just renewed them; I placed each renewal application with old books in their own envelope with their own separate checks in another envelope to save on postage. Inside envelopes were addressed just without postage.
The same day we both got separate priority mail envelopes back. My wife got a new-gen passport and I did not both have the same issue dates.
Just a reference point, anyway glad I have the old one, feels lighter to carry
