The short answer is yes! You can and should update your wedding registry over time. Creating your wedding registry is not a one-off to-do. As guests start to purchase items off your registry, you'll want to add more so there are always lots of options at different price points. This also means you'll want to register for the items you need and want the most first. Though this is a continuous process, we especially recommend updating your registry two weeks before and two weeks after your wedding, since this is when most gifts are purchased.
