MIR4 Codes: Active and Expired (June 2026)
Last checked May 28, 2026 (UTC)
Wemade drops MIR4 codes around updates and events in this open-world MMORPG, and most of them hand you Diamonds and growth items. I keep the working ones rounded up here so you can claim and get back to grinding.
MIR4 codes are coupon codes Wemade posts on the official MIR4 channels and during update events for free Diamonds (premium currency), Copper, Darksteel, and EXP or growth items. MIR4 is an open-world MMORPG with big, messy PvP, where you pick a class and grind gear, skills, and Darksteel out in the world. Diamonds buy convenience and growth packs, Copper covers upgrades, and Darksteel feeds your power progression. Code rewards just speed up the gear and character growth that decides where you stand in those open-world fights.
Quick tip. I'd pour code Diamonds into character growth and gear enhancement, not cosmetics. Everything here is driven by your power score in open world and PvP, so lasting gear and stats actually raise your combat strength, while a nice outfit does nothing for it.
New codes turn up around major updates, server milestones, and seasonal events. They run on a normal MMORPG timeline, so each one expires after a window. You redeem them in game through the coupon option in the settings menu, or on the Wemade redemption page, and they're case sensitive, so copy carefully.
- Redeem in game through the settings coupon option, or on the Wemade page.
- Most MIR4 codes give Diamonds, Copper, and growth items.
- They expire once their event window's over, so redeem early.
- Each code is single use per account.
- Codes are case sensitive, so use the Copy button instead of typing.
Active MIR4 codes (4)
Use the Copy button next to each code. They're case sensitive, so paste rather than type, and redeem early because they expire once the event window's done.

If a code says invalid, it's expired or you've already used it. Check the official MIR4 channels for the current set.

How to redeem MIR4 codes
MIR4 gives you two ways in: the coupon option in the in-game settings menu, or the Wemade redemption page. Whatever you claim lands in your in-game mailbox.
In game (settings coupon option)
- Open MIR4 and tap into the settings menu.
- Find the coupon or redemption code option.
- Enter the code exactly as shown, since it's case sensitive.
- Confirm, then open your mailbox to claim the Diamonds and items.
On the Wemade redemption page
- Open the official Wemade MIR4 coupon page in any browser.
- Sign in with the account linked to your character.
- Enter your character info and the coupon code, then confirm.
- Launch the game and check your mailbox for the rewards.
If a code gets rejected, it's usually expired or already used on this account. They're case sensitive, so paste from the Copy button to rule out a typo.
MIR4 codes FAQ
What do MIR4 codes give you?
Mostly Diamonds, Copper, Darksteel, and EXP or growth items. Diamonds buy convenience and growth packs, Copper covers upgrades, and Darksteel feeds your power progression. It all speeds up the gear and character growth that drives your strength.
How should I spend code Diamonds?
On character growth and gear enhancement. MIR4 lives and dies by your power score in open world and PvP, so lasting gear and stats raise your combat strength while cosmetics don't move it at all. Put progression first.
Why does my code keep failing?
Three usual causes. It expired, you already redeemed it on this account, or you mistyped it. The codes are case sensitive, so paste from the Copy button to keep the exact form.
Where do I redeem MIR4 codes?
Two places. In game through the coupon option in the settings menu, or on the official Wemade MIR4 coupon page in a browser. Either way the rewards land in your in-game mailbox, ready to claim.
Do codes work on the PC client?
They do. The MIR4 PC client shares your account with mobile through Wemade Play, so redeem on either one (or the web page) and the Diamonds and items hit the same character no matter where you play.
Where do I find the newest MIR4 codes?
Follow the official MIR4 channels and Wemade's announcements. New MIR4 codes drop around updates, server milestones, and seasonal events, usually announced first on those channels with the patch notes.
