One number per change
The format goes up whenever something about packs changes, and releases that share a number read packs in exactly the same way.
Pack Format Versions
Every resource pack format number Minecraft Java has used, which releases read it, and what changed for pack makers along the way.

How it works
How Minecraft pack formats work
A pack whose format does not match the game still loads after a warning, but things inside it may quietly stop working.
1.21.9 and later
pack.mcmeta uses min_format and max_format to declare a range. Older keys are still needed for packs that also support older versions.
Snapshots
Snapshots have pack formats of their own, between the release numbers. This table lists full releases only, which is what servers run.
Step by step
How to set your pack format
The number goes in pack.mcmeta, and it is the first thing Minecraft reads.
- 1
Find your version
Look up the Minecraft version your pack is made for in the table at the top of this page. Releases that share a row share a pack format, so one number covers all of them.
- 2
Write it down
Put that number in pack.mcmeta as pack_format, or declare a range of formats to support several versions at once. The pack.mcmeta generator writes either one for you.
- 3
Check the pack
Run the finished pack through the resource pack checker. It reads the format back, tells you which Minecraft versions it covers, and flags any rule the newer versions enforce.
