How to read Union Arena, Fusion World and Digimon card numbers
What UE24BT/REZ-1-053, FB11-084 and BT25-104 mean, and why searching by card number is the quickest way to find the exact card you want at the best price.
Every card in these three games carries a code that says which set it is from and where it sits in that set. Searching by that code is the most reliable way to find one exact card.
Union Arena: UE24BT/REZ-1-053
- UE24BT: the product it came from (UE booster 24, Re:ZERO).
- REZ: the series.
- 1: the series' volume. A second volume of the same anime is printed as 2.
- 053: the card's number. Action Point cards use AP and a number instead (REZ-1-AP05).
Stores usually write only the last part, REZ-1-053. The star versions of a card share its number, so check the rarity too.
Dragon Ball Super Fusion World: FB11-084
FB11 is the eleventh booster set and 084 the card's number. Starter deck cards start with FS (FS02), and some other products use their own prefix, like ST01 in Story Booster 01. Alternate-art versions keep the base card's number.
Digimon Card Game: BT25-104
BT25 is booster set 25, EX marks extra boosters and ST starter decks; the number follows. TCGplayer adds the rarity after it (BT25-104 SEC), and Rare Pull and alternate-art versions keep the base card's number.
Search by number
Type a code like FB11-084 or BT25-104 into the search box on any page to jump straight to that card's prices at every store.
