Pokémon TCG set codes like ME2, SV3, and SV3.5 can look confusing at first — but once you understand the pattern, they’re one of the easiest ways to identify an expansion quickly. This guide explains what set codes mean, why “.5” exists, and how to use codes to browse expansions and sealed products on 120HP.
What is a Pokémon TCG set code?
A Pokémon TCG set code is a short label used to identify a specific expansion within a broader era. Collectors, sellers, and grading companies use set codes because they’re quick, consistent, and reduce confusion — especially when different sets have similar names.
Instead of writing the full expansion name every time, a code like SV3 instantly tells you which era and release order the set belongs to.
How modern set codes work (Scarlet & Violet era)
Modern expansions usually follow a simple pattern: an era prefix + a number that increases as new main sets are released. In the Scarlet & Violet era, you’ll commonly see codes like:
What does “.5” mean in Pokémon set codes?
When you see a code like SV3.5, the “.5” typically indicates a special expansion that sits between two main sets. These sets often have unique product formats and can be particularly popular with collectors.
Mega Evolution era set codes (ME1, ME2, etc)
Some eras use a custom prefix rather than a generation label. For example, Mega Evolution era sets can be grouped with an ME prefix followed by the release number within that era (e.g. ME1, ME2).
Why set codes matter for collectors
Understanding set codes makes collecting cleaner and faster. It helps you:
- Identify an expansion quickly when browsing sealed products.
- Track what you’re collecting by era and release order.
- Avoid confusion when set names are similar.
- Reference cards more accurately when buying, selling, or grading.

FAQ
Are set codes official?
You’ll see set code conventions used widely across the hobby (collectors, listings, databases). The exact format can vary by era, but the purpose is always the same: to identify an expansion quickly.
What does “.5” mean in a set code?
A “.5” typically indicates a special expansion that sits between two main sets in the release timeline (for example, SV3.5).
Why do some eras use different prefixes?
Some eras use a custom prefix to group expansions (for example, an “ME” prefix for Mega Evolution era) while still keeping a clear release order.
Tip: If you’re ever unsure which set a product belongs to, start with the expansion name — then use the set code as your quick confirmation.
