Are you using a Computer?
Log in to your account on the website. Look for the "Build Your Registry" tiles at the top of the page. Scroll over until you see "Anyone else along for the ride?" and click that tile. You may have to click on "See All" to show all your tiles. A pop-up will load where you can fill in your partner's information and invite them to edit the registry with you.
Are you using the app?
Go to the menu bar (at the top left side of your screen) and select Registry > Partner Info. Simply enter their information and we'll send them an invite so they can manage the registry alongside you.
