Companion to the set and series list and to How to play the Gundam Card Game. This is the lookup page: how a card number is built, what each part means, and where the system stops being reliable.
Quick answer
A Gundam card number does not index the anime. It indexes the set’s own layout: card type first, then colour, then a rough rarity order inside each colour block. GD01-001 is not “the first Gundam card”, it is the first blue Unit in Newtype Rising, which happens to be the RX-78-2 because the set puts its Legend Rares at the front of each colour block. Search for a card by its series and you will not find it this way. Search by the number and you will.
That has a practical consequence. The number tells you what kind of card it is and roughly how the set is arranged, which is enough to navigate a checklist, verify a listing and spot a card that does not belong to the set it is being sold as. It does not tell you which printing you are looking at, and that distinction is where most lookups go wrong.
The three parts of a number
Every card carries one string in the top-right corner, next to the rarity letter. It reads as three parts, and each part does a different job.
- Prefix. Which product the card belongs to. GD for main boosters, ST for starter decks, EB for the extra booster.
- Serial. A three-digit position inside that product, from 001 upwards. This is the part that follows the set’s internal layout.
- Rarity letter. C, U, R, LR, SP or LK, printed beside the number. On a parallel, the same letter carries a + suffix.
Read together, GD01-118 U describes a specific card in a specific product at a specific tier. It does not describe a printing, because the same string appears on the beta version, the SP version and the promo version of that card.
Prefix families
Most confusion comes from prefixes that are not sets. A checklist of main boosters will not list any of the resource or token families, and they are common enough to matter.
| Prefix | What it is | Example |
|---|---|---|
| GD | Main booster, numbered in release order | GD05 Freedom Ascension |
| ST | Starter deck, with cards that never appear in a booster | ST01 Heroic Beginnings |
| EB | Extra booster; its cards carry an EX marker | EB01 Eternal Nexus |
| EXR / EXB | EX Resource and EX Base cards | EXR-009 |
| R / RP | Resource cards, and their promo versions | R-002 |
| T | Token cards, including judge and event tokens | T-005 |
| P | Promo printings of existing numbers, from events and organised play | Tournament and championship cards |
Two things follow. Resource and token cards are not part of a set’s numbered pool, so a checklist that stops at the Legend Rares is complete for deckbuilding and incomplete for collecting. And promo printings borrow the number of the card they reprint, so a promo of a GD01 card is still a GD01 number and will not appear under a promo prefix.
What the serial actually encodes
The serial is the interesting part, and GD01 shows the pattern most clearly because its block boundaries can be read straight off the card list.
| Numbers | What sits there |
|---|---|
| 001–022 | Blue Units, opening with the three blue Legend Rares |
| 023–043 | Green Units |
| 044–064 | Red Units |
| 065–086 | White Units |
| 087–098 | Pilots, cycling blue, green, red, white three at a time |
| 099–122 | Commands, cycling the same four colours six at a time |
| 123–130 | Bases, two per colour |
The order of the colour blocks is fixed at blue, green, red, white. Within a block, the highest tier tends to come first: GD01 opens with three Legend Rare Units, then moves down through Rare, Uncommon and Common. The pattern is not perfectly mechanical, because a few cards are paired with a sibling and placed beside it rather than by tier, but it holds closely enough to navigate by.
What the serial does not encode is the anime. In GD01, SEED units land in the red and white blocks, Unicorn units in the blue and red blocks, and Wing units in the green block. If you are looking for a card from a specific series, the number will not help you; a database search by series will.
Where the index breaks
Three exceptions will send a lookup wrong, and all three are common.
SP reprints. From GD03 onwards, sets seed special reprints of older cards, and those printings keep the original card number. A GD01 Command pulled from a GD03 pack is still GD01-118. If you find an SP in a box and search the set it came from, it will not be there.
Beta printings. Edition Beta shipped before the launch, and its cards carry the numbers they later kept. A beta card and a booster card can share a number and a rarity letter and still be different objects with different supply.
Reprints inside other products. Starter decks, the Deck Build Box and premium sets reprint existing cards under their original numbers. A card appearing in four products still has one number, so the number will not tell you which product a copy came from.
Looking up a card in four steps
- Read the prefix, then decide what kind of product you are looking at. GD means a booster and a numbered pool; ST means a deck and cards with no booster source; EB means the smaller extra-booster pool.
- Use the serial to place the card inside the set. The block tells you the type and the colour before you have read a word of the card.
- Check the suffix before you check the price. A plain number and a + number are different objects, and the suffix changes what you are looking at far more than the letter does.
- If a card seems to be in the wrong set, suspect a reprint. SP and promo printings keep their original numbers, so a card can legitimately appear in a set that does not list it.
Storing an indexed collection
A collection sorted by number is the only kind that stays searchable, because the number is language-independent and does not change with a reprint. Sorting by series or by rarity both break as soon as a set adds a tier.
That means the storage decision is about keeping the order visible. A box with dividers labelled by prefix and block is more useful than a binder ordered by colour, and a matte sleeve on every card is what makes re-sorting possible without abrasion. For the cards that carry real value, a 3×4 toploader keeps them out of the sorted stack entirely, which is the point: the chase cards should not be in the sequence you reshuffle.
One habit worth building early: write the printing on the divider, not on the sleeve. A beta copy and a booster copy of the same number look identical from the back, and six months later the divider is the only record you will have.
Where this sits
The parent page is the set list, which gives the prefixes in release order. For the tiers behind the letters, the rarity ladder. If you are using a number to buy across regions, the editions comparison explains why the number is the only stable search term.
Frequently asked questions
What does the number on a Gundam card mean?
Prefix, serial and rarity. The prefix is the product, the serial is the card’s position inside that product, and the letter is its tier. None of the three refers to the anime.
Why do two cards have the same number?
Because they are the same card in different printings. Parallels, beta printings, SP reprints and promos all keep the original number, and the suffix or the product is what separates them.
How do I find a card if I only know the anime?
Use a card database and search by series rather than by number. The numbering deliberately does not group by series, so a series search and a number search answer different questions.
What does the EX marker mean on an EB01 card?
That the card comes from the extra booster rather than a mainline GD set. It sits on the same rarity ladder as everything else.
Are card numbers the same in every language?
Yes. The number is language-independent, which is what makes it usable for buying from another region. Only the text on the card changes.
What the numbering looks like on the card
Three cards whose numbers place them before you read anything else on the face.

Nothing on this page is investment advice. Block boundaries are given for GD01 because they can be read directly from its card list; later sets follow the same type-then-colour order but should be checked against their own lists.
