Quick answer
A One Piece card number has three parts: a set prefix that names the product (OP01, EB02, ST13), a three-digit number that identifies the card inside that product, and sometimes a suffix such as _p1 or _r1 that marks an alternate treatment of the same card. CardSpicy uses the code as the primary key for every card we list, because it is the only identifier that does not change when a card is reprinted.
The suffix is the part people get wrong. It does not mean a different card — it means the same card, drawn again.
Card numbers look like administrative detail until the moment you are comparing two listings of what claims to be the same card and the prices do not match. At that point the code is the only thing that settles it, because the name is not unique and the artwork is not a number.
The three parts
| Part | Example | What it tells you |
|---|---|---|
| Set prefix | OP01 |
Which product the card belongs to. Two letters for the product line, two digits for the wave. |
| Card number | -016 |
The place of this card inside that product. Three digits, printed after the hyphen. |
| Suffix | _p1, _r1 |
An alternate treatment of that same card. Absent on the base printing. |
Put together, OP01-016 is the sixteenth card of the first booster. OP01-016_p1 is the same card and the same number, in a second treatment.
The set prefixes in use
| Prefix | Product line | Products |
|---|---|---|
OP |
Booster packs, the main numbered waves (OP-01 to OP-17, with two entries labelled OP14-EB04 and OP15-EB04) | 17 |
EB |
Extra boosters, smaller sets between the waves | 3 |
PRB |
Premium boosters, reprint sets | 2 |
ST |
Starter decks and the two Ultra Decks | 36 |
The starters are numbered in one continuous range, so ST-10 and ST-13 are Ultra Decks while their neighbours are ordinary starter decks. The prefix alone does not tell you which is which; the product does.
What the suffix means
A card that has been given more than one treatment carries the same number every time. The suffix is not part of the card’s identity — it is an index into the treatments that exist.
- No suffix. The base printing: the card as it first appeared in that set.
_p1…_p9. Parallel treatments — different artwork, different rarity label, same number and same effect._r1,_r2. A second class of treatment, also sharing the base card’s number, stats and effect.
In the database there are 1,086 distinct cards that carry at least one alternate treatment, and 2,059 of the 4,844 individual entries are a treatment of something else. Counting treatments as separate cards is the single most common counting mistake in this game.
Where to find it on the card
The code is printed on the card itself, normally at the bottom of the card face alongside the set symbol, and it is the same code the official database indexes by. For a card in a slab, the label carries the card’s name and grade; the code is still on the card under the plastic, which is why a photograph of the card face is the thing to ask for when a listing is ambiguous.
Frequently asked questions
Is OP01-016_p1 a different card from OP01-016?
No. It is the same card, with the same number, the same stats and the same effect, printed in a second treatment. Treating the alternate art as a separate card is the most common counting mistake in the game.
What does the _p mean in a card number?
It marks a parallel treatment — alternate artwork of a card that already exists in that set. The digits after the p are an index into the treatments, not a version number and not a quantity.
Why do two products share a code like OP14-EB04?
The official database labels two of the booster entries that way, joining an OP number to an EB number. It is the official label rather than a printing error, and it is why the set list on the index page shows the code exactly as Bandai publishes it.
Do starter decks use the same numbering?
Yes. Starter decks are numbered ST, in one continuous range that also contains the two Ultra Decks. A card from a starter deck is identified by its ST code in exactly the same way a booster card is identified by its OP code.
