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.
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.
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.
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.
