Pokémon TCG set codes like ME02, SV03, and SV03.5 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 Pokémon set codes mean, why “.5” exists, and how collectors can use codes to browse expansions, sealed products and card listings more confidently.
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, grading companies and card databases often use set codes because they are quick, consistent and reduce confusion.
Instead of writing the full expansion name every time, a code like SV03 quickly tells you which era and release order the set belongs to.
How modern set codes work
Modern Pokémon TCG expansions usually follow a simple pattern: an era prefix followed by a number. In the Scarlet & Violet era, that prefix is commonly shown as SV.
What does “.5” mean in Pokémon set codes?
When you see a code like SV03.5, the “.5” usually indicates a special expansion that sits between two main set releases. These sets often have different sealed product formats and can be especially popular with collectors.
Main sets are usually whole numbers, such as SV01, SV02 and SV03.
Special sets are often shown as decimal releases, such as SV03.5.
Practical takeaway: if you’re looking for a specific expansion, the set code is often faster than relying on the name alone.
Mega Evolution era set codes
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.
Useful for identifying the first main set in the era.
Used to track the next main release in order.
A decimal code can indicate a special release between main sets.

FAQ
Are set codes official?
Set code conventions are widely used across the hobby, including collectors, listings and card databases. The exact format can vary by era, but the purpose is the same: to identify an expansion quickly.
What does “.5” mean in a set code?
A “.5” usually indicates a special expansion that sits between two main set releases, such as SV03.5 sitting between SV03 and SV04.
Why do some eras use different prefixes?
Different eras can use different prefixes to group expansions clearly. For example, an ME prefix can be used to group Mega Evolution era sets.
Tip: If you’re unsure which set a product belongs to, start with the expansion name, then use the set code as a quick confirmation.
