LONDON (AP) — Time to check that mailbox.

Kensington Palace said Thursday that invitations for the wedding between Prince Harry and his American fiancée Meghan Markle have been dispatched.

Some 600 people have been invited to the May 19 nuptials at St. George's Chapel at Windsor Castle. All 600 have also been invited to a lunchtime reception given by Queen Elizabeth II at St George's Hall.

The invitations, which are beveled and gilded in gold along the edges, feature Prince Charles' three-feather badge. They were made by Barnard & Westwood, which has held the Royal Warrant for printing and bookbinding since 1985.

Harry and Markle will also celebrate with some 200 guests at a private evening reception given by Prince Charles.

The palace declined to comment as to who is on the list.
