“This is for members of the public who have kindly suggested that they wanted to give the couple a gift,” a spokeswoman tells PEOPLE.
The bride- and groom-to-be have been “touched by the goodwill shown them” since their engagement last November and are asking people to give money to a special charitable fund.
The various charities to be funded reflect the couple’s interests and, in many cases, are little-known and do not necessarily have existing royal patronage. Among them: an anti-bullying campaign, as well as those that provide help to communities through the arts and sports.
There is also a group that supports those in military families, and others benefitting organizations based in New Zealand, Australia and Canada.
The charities have been chosen because they have a “particular resonance” with William, 28, and Kate, 29, and “reflect issues in which the couple have been particularly interested in their lives to date,” a statement says.
Guests invited to the big day April 29 will have “other arrangements” should they wish to give the couple a personal gift, a palace spokeswoman tells PEOPLE.
Donations, which are being accepted in six currencies, can be made through the Prince William & Miss Kate Middleton Charitable Gift Fund Web site, where a complete list of the charities may be found.
