There isn't one to find. Wishpicks doesn't keep an address on a wish, on a wishlist, or on your profile, so there's nothing to fill in. You arrange delivery privately with the gifter instead.
Nothing's broken or missing from your account. Wishpicks helps people pick the right gift. It isn't a shop, it doesn't handle shipping, and so it never asks for an address, postal code, recipient name, or phone number.
Why there's no field
Reserving a gift only marks that someone plans to get it. The gifter buys at the store and works out delivery with you, so Wishpicks has no reason to hold your address. There's a second reason too. A wishlist set to Anyone with the link can be opened by anyone who's been sent it, and a home address doesn't belong on something that travels that easily.
What to do instead
Leave a short, neutral hint on the wish, like "Message me for delivery details."
Send your real address through a private channel you trust, to the one person who's buying.
Keep it off any note that ends up back on the wishlist.
Good to know
The country setting on your profile is just a two-letter country code, used for pricing and region. It isn't a delivery address and gifters don't see it.
Don't rely on the gifter's reservation note either. It stays hidden from you to protect the surprise, so it can't pass details back and forth.
