2 questions. 1. Is a separate RSVP card standard with invitations now, or do people still just do phone numbers? 2. I've seen people here say it's not appropriate to include where you're registered at in the invites? I looked around but didn't see much more than that. I've never heard this so Im not sure why, assuming it's rude, but how do you let people know where you're registered at? Especially if you're not having a bridal shower?
Re: RSVP and wedding registry
2. No it's not appropriate to include registry information (or any gift information) on invitations since gifts are never required. People who want to give you a gift will ask you or your parents, bridal party, etc. or they will google your names.
If you haven't done any form of invites, or save the dates on your save the dates, you can also list your wedding website link on them and as PP stated, you can put registry info there, otherwise wait til someone else asks you, never be the first to bring it up otherwise.
But you're right, it's never appropriate to include any mentions of gifts or registries, including "no gifts" or similar requests in wedding invitations. Should someone ask you about your registry, it's then certainly acceptable to tell them where you're registered. But they have to be the one to initiate the discussion.
