“It’s a Charizard” can start a conversation, but it doesn’t identify a Pokémon card well enough to buy, sell, or check off a wishlist. The same Pokémon appears in different expansions, with different illustrations, numbers, languages, and treatments. Even two copies with matching artwork may need a closer look.
The useful question is: which printing are you actually holding? Start with the card’s name and identifying details, then use an official reference to connect them. Leave anything uncertain open until you can verify it. A clear “version not confirmed” note is better than confidently recording the wrong card.

Read the name, then look for the number and expansion

Copy the printed card name carefully, including meaningful suffixes such as ex or EX where present. Then find the collector number and the expansion identifier. Their presentation has changed across eras, so don’t expect every Pokémon card to put every clue in the same place.
A number like 207/198 is useful as a whole. Keep both parts and the expansion name with it. Avoid searching only the larger, more prominent numbers on the card, such as HP or attack damage. Those describe gameplay information rather than the collector identity you’re trying to establish.
Older-style cards can also display a Pokédex number in the descriptive line below the illustration. That identifies the Pokémon species, not the particular collectible printing. If a Charizard shows No. 006, that alone doesn’t tell you which Charizard card you own.
Use the database to narrow the possibilities

The official Pokémon database guide describes searches using card name, expansion, rarity, and illustrator. Start with the details you can read clearly, then compare the matching entry with the actual card. Don’t force a result just because the character looks familiar.
The illustrator can be especially helpful when you’re organizing by artwork. Keep the credit as printed or documented, rather than guessing from the style. For buying, the image is another check alongside the number and set; it doesn’t replace them.
Treat a database match as identification evidence. It doesn’t authenticate the physical card, establish its condition, or tell you what every finish looks like under different lighting. Those are separate questions.
A modern example: Dondozo 207/198

The existing English reference for Scarlet & Violet Dondozo 207/198 records Illustration Rare and illustrator AKIRA EGAWA. The corresponding official Portuguese entry also shows the number and illustrator. Keep language in your own record; an entry in another language is not a substitute for confirming the physical version you intend to buy.
A useful wishlist line would therefore identify Dondozo, Scarlet & Violet, 207/198, the desired language, and the relevant condition or format. “Dondozo full art” might find something in a search, but it leaves more room for two people to mean different items.
The number being above the denominator isn’t a reason to reject this example as a typo. Compare it with the official record rather than deciding that all card numbers must fit the simplest-looking pattern.
An older example: separate species information from card identity
Pokémon’s official XY—Evolutions translation reference identifies Charizard with collector number 11/108 and illustrator Mitsuhiro Arita. Its descriptive species line includes No. 006. Those are different numbers doing different jobs.
This is a bounded example from XY—Evolutions, not a guide to every vintage Charizard or every older layout. It also doesn’t mean that familiar artwork makes two releases interchangeable. Keep the actual expansion, collector number, language, and visible printing details together before comparing offers.
If you are working with an earlier era, an unusual promo, or a printing that isn’t covered by the reference you found, pause the comparison and locate evidence for that specific card. A modern rarity explanation shouldn’t be stretched backward just because it is easier to find.
Finish the record with the details that distinguish your copy

Once the basic identity is clear, note language, rarity, finish, stamps, and any other verified version details that matter. Record condition separately. Two copies can share an identity and differ in wear; two apparently similar copies can be different versions before condition even enters the conversation.
For your own collection, the record only needs to be detailed enough to support what you do with it. A favorites binder may need less detail than a variant-completion project. But if you would be disappointed to receive a different version, put that difference on the wishlist.
A photo of the front and back can help you revisit a question without repeatedly handling the card. Keep the original privately and use a clear, limited copy when asking for help. If a feature remains unclear, describe what you can actually see instead of naming the version you hope it is.
Quick questions
Is the collector number enough by itself?
Keep the expansion and language with it, plus any relevant finish or printing distinction. One field rarely does every job.
Can the same artwork appear on different cards?
Artwork alone is not a complete identity check. Match the release and printed details before assuming two offers describe the same collectible.
Does an official database match prove my card is genuine?
No. Matching a reference helps you identify the intended card. Authentication and condition assessment require their own evidence.
