If both of you mail anywhere and your countries differ, you can still swap. Request swap, the swap card, and the host desk show a reminder: no liquids, no perishable food, no cash. Use a customs form if your post office asks. Keep it postal-safe and legal in both countries.
Same country only
- On My profile, Where I’ll mail can be Same country only.
- That blocks new requests both ways — you won’t request someone abroad, and they can’t request you.
- Directory → My country filters to people in your country.
