The Archive

Promos, special editions, and miscellanea that don't fit neatly into a numbered era — Pokémon Center exclusives, McDonald's promos, POP Series tournament cards, Burger King throwbacks, and other curiosities.

About the Codex

How many Pokémon TCG sets are there?

As of May 26, 2026, ChaseDex tracks 216 Pokémon TCG sets containing 28,877 cards across every printing era from Base Set (1999) to the current Mega Evolutions block.

What is a set symbol?

The set symbol is a small icon printed on the bottom-right corner of every Pokémon card. Each expansion has a unique one. Combined with the rarity symbol and regulation mark, it identifies which set a card came from.

What is the difference between a set and an era?

An era is a multi-year design block in which all sets share branding and mechanics — Scarlet & Violet, Sword & Shield, Sun & Moon, and so on. A set is a single expansion released within that era. Most eras contain 4–17 main sets plus promos.

Why are some sets in the Archive instead of an era?

The Archive holds sets without a clean release date or a definitive era assignment — Pokémon Center exclusives, retailer promos, POP Series tournament prizes, Burger King and McDonald's distributions, and other miscellany. They’re honest curiosities rather than mainline expansions.
