Vivillon is one of the few Pokémon in Pokémon GO you genuinely cannot complete alone — its 18 wing patterns are tied to real-world regions, and you unlock them through postcards sent by friends who live there.
How the Vivillon mechanic works
- Friends send you gifts, and every gift comes with a postcard from where it was spun.
- Pin a postcard to save it to your postcard book (you can pin at most 3 of your own postcards per day — friends' postcards are how you go faster).
- Pinned postcards fill the Vivillon Collector medal for that region: 3 pinned postcards unlock your first Scatterbug encounter of that pattern, then 9 for the second, 15 for the third and every one after.
- Repeat for all 18 regions. That means friends spread across the whole world.
The catch: most people's friend lists cluster in their own country. If everyone you know is in Norway, you will never see the patterns tied to Asia, South America or Oceania.
Getting friends in the right countries
This is exactly the problem code boards are bad at — they rarely tell you where a trainer is from. Two faster routes:
- Browse codes by country — our live pool is tagged by country, so you can see exactly which regions are available right now (Japan and South Korea are usually well-stocked, which Western code boards almost never have).
- Grab fresh codes with one tap — every code shows its country when you claim it, and you never get the same code twice.
Once they accept, exchange gifts and pin the postcards — the pattern progress only counts pinned postcards, not opened gifts.
Tips from collectors
- Check the Vivillon collector page in-game (Pokédex → Vivillon) to see which regions you are missing before hunting codes.
- Nickname friends by their pattern region so you know who to keep long-term.
- Keep the friendship alive: a friend who stops sending gifts stops sending postcards. Friends who mark themselves as daily gifters are worth their weight in Stardust.
- The dedicated community at r/VivillonCollectors organises swaps by region if you need the last rare patterns.
FAQ
Do I need to visit those countries myself? No — only the postcards need to come from there, via gifts from friends.
How many postcards per pattern? Three pinned postcards from the region unlock the first encounter; later encounters of the same pattern need 9, then 15.
Can I pin postcards retroactively? No, you can only pin a postcard when you receive the gift — so start pinning as soon as your new international friends send their first gifts.
