Put simply, a 'Party ID' allows you to quickly and easily group guests together into a single Party so that one guest can RSVP on behalf of themselves and the other members of that Group / Household. If all of your guests are individuals, you should see this article about how you can bypass this step.
Let's say you have a family of 4: John Doe, Jane Doe, Julie Doe, and Jimmy Doe. During the RSVP process, these guests should be asked to RSVP together -- rather than each guest having to RSVP individually, right?
Assigning individuals a Party ID Number lets RSVPify know which individuals should be grouped together.
John Doe: Party ID # = 3
Jane Doe: Party ID # = 3
Julie Doe: Party ID # = 3
Jimmy Doe: Party ID # = 3
Note the red text in the Party ID Column for the Doe Party:
In our example, we've assigned all 4 members of the Doe family the same party number (3), ensuring that the system will group these 4 guests together.
