Before you say “I do” to your beloved, there are many small and big decisions to make, such as what to wear and whom to invite ― but there is one tiny, yet monumental, decision that too many couples overlook.

It’s a decision that every couple faces when creating an online wedding registry: How private or public should this list be to anyone searching for this information online? The choice is yours, but privacy experts strongly recommend setting up your registry to be as private as possible.

“Some registry websites are pretty locked down about privacy and security, and they won’t make the address public, or they’ll keep other information private, unless you have some of password-protect [option turned on], but in a lot of cases, they’ll share the information because it’s practical,” said Calli Schroeder, senior counsel for the Electronic Privacy Information Center.

But what is convenient for shipping is not necessarily the safest option for your family.

That’s because long after your wedding is over, this identifiable information can come back to haunt you.
