You’ve woken in the monolith. The Trekkers call you Boss. And somewhere in those luminescent corridors is a truth worth chasing—but assembling the team that can get you there takes resources. That’s where codes come in.
There’s a catch most guides gloss over: Stella Sora’s redemption system works differently depending on your platform, and on mobile, rewards don’t appear automatically after you confirm a code. You have to go claim them from your mailbox. Missing that step is the most common reason players think a code “didn’t work.” The complete process, for both platforms, is below.
All Active Stella Sora Codes — April 2026
| Code | Confirmed Reward | Status | Notes |
|---|---|---|---|
| CLAW2026 NEW | Free rewards (exact contents vary by account) | Active | Latest code — redeem first |
| 2025XMAS | Free rewards | Active | Holiday code — expiry unconfirmed |
| BOSSGIFT CONFIRMED | 100 Stellanite Dust | Active | Only code with a verified reward amount |
The active list is short because Stella Sora is still a relatively new release—codes are quite rare at this stage, with Yostar releasing them around major updates, milestones, and seasonal events rather than on a fixed schedule. More will come; the Discord is where they appear first.
The Two-Step Redemption Process — How It Actually Works
Here’s what nearly every guide misses: entering a code and hitting Confirm is only step one. The rewards don’t land in your inventory automatically. They arrive as a mail message, and you have to open the in-game mailbox and manually collect them. If you skip that second step, you’ve confirmed a code but received nothing.
Don’t forget the mailbox
After a successful code redemption, log back into Stella Sora and open your in-game mailbox (the envelope icon near the Menu button). Rewards can take up to a minute to arrive. If the mail isn’t there immediately, wait 60 seconds and refresh before assuming the code failed.
Redemption method by platform
Yostar runs two different redemption flows—one for PC players and one for mobile. Both require your UID. Use the correct method for your platform.
PC / Steam Deck
- Complete the first bounty trial to unlock the menu system.
- Click your account level in the top-left corner to open your profile and copy your UID.
- Click the Menu icon (three horizontal lines) in the top-right corner.
- Select Redeem Code at the bottom of the menu.
- Enter your UID and paste the code. Hit Confirm.
- Open the in-game mailbox to claim rewards.
Mobile (iOS & Android)
- Complete the tutorial and create your character — redemption fails on uncreated accounts.
- Open your profile and copy your UID (found below your username).
- Open a browser and go to stellasora. global/gift
- Enter your UID in the first field, then paste the code in the second.
- Hit Confirm.
- Return to the game and claim rewards from your in-game mailbox.
Where to find your UID
| Platform | How to find your UID |
|---|---|
| PC | Click your account level in the top-left → UID displayed with a copy button in the top-right of the profile screen |
| Mobile | Tap your avatar (top-left); the UID appears below your in-game name. Tap the copy icon to avoid transcription errors. |
| Alternative (all platforms) | Menu button (top-right) → User Center → UID listed below your email address |
Error Messages — Causes and Fixes
| Error | Cause | Fix |
|---|---|---|
| Invalid UID format | UID entered incorrectly, or no character created yet | Create your character in-game first. Copy your UID directly from the profile screen — don’t type it manually. Your UID is a unique 9-digit number. |
| Code already redeemed | You’ve used this code on this account before | Expected behavior. Each code is one per account, final, and non-refundable. Move to the next code. |
| Invalid / expired code | Code has expired or case-sensitive typo | Copy-paste directly rather than typing. If the code still fails, it has likely expired—visit this page for an updated list. |
| Rewards not appearing | Mailbox not checked, or mail still in transit | Wait up to one minute after confirming, then open the in-game mailbox and manually claim the reward. Restart the game if it still doesn’t appear. |
| Limited region | VPN active or there’s a region mismatch | Disable VPN. Some codes are server-specific (global, JP, etc.). Ensure the code is intended for your region before attempting to use it. |
| Redemption unavailable | Tutorial / Bounty Trial not completed | Complete the first Bounty Trial on PC, or finish the full tutorial on mobile. The redemption system gates are behind the scenes on both platforms. |
What Stellanite Dust Actually Does
Since BOSSGIFT is the only code with a confirmed reward quantity, it helps to understand the value of what you’re getting. Stellanite Dust is Stella Sora’s primary premium currency—used for Trekker summons, pulling gear, and progressing through banner events.
| Currency / Item | Primary use | How to get more |
|---|---|---|
| Stellanite Dust | Summoning Trekkers and gear on active banners. The core gacha pull currency. | Codes, daily login rewards, event completions, Monolith clear milestones |
| Summoning Tickets (Cerulean Tickets) | Direct pulls on the gacha — one ticket per attempt. Use it on rate-up banners for best efficiency. | Everbright Wishes, login streaks, event rewards, codes |
| Discs | Equippable gear that modifies Trekker stats and unlocks set bonuses in the Monolith. | Monolith runs, upgrade shops, code rewards |
| Resumes (EXP items) | Levels up Trekkers without manual combat grinding. More valuable the further you progress. | Daily quests, event rewards, code drops |
Things most Stella Sora guides don’t mention
- Creator codes work differently. Sponsored codes from content creators are sometimes exclusive — you can only redeem one creator code per account per campaign. Use the code of your preferred creator since it supports them directly, but you may not be able to stack multiple creator drops.
- New codes drop a couple of times a week during active development windows—PCGamesN notes this is more frequent than typical for a Yostar title at launch. This cadence won’t last indefinitely, so redeem everything available now.
- You get 20 free rerolls at account creation. You can save up to five of these pulls. When rerolling, target at least one top-tier 5-star Trekker plus a solid 4-star in the same pull before committing to an account.
- Redemptions are final. Per the official Yostar redemption rules, confirmed codes cannot be canceled or refunded. Always verify you’re logged into the correct account before redeeming, especially if you have multiple accounts.
- The Discord link is inside the game. No need to search — you can find a link to the official Stella Sora Discord server in the third tab of the in-game Gifts section. It’s the fastest source for new code drops.
Where New Stella Sora Codes Come From
Yostar releases codes around predictable triggers: major game updates, server maintenance periods, milestone celebrations, and seasonal events. Understanding the pattern means you can anticipate drops instead of scrambling after the fact.
| Source | Speed | What to look for |
|---|---|---|
| Official Discord | Fastest | Announcements and dedicated code channels. The link is accessible via the in-game Gifts section (third tab). |
| X (@StellaSoraEN) | Fastest | Event announcements and milestone posts frequently accompany code drops. |
| YouTube (@StellaSoraEN) | Medium | Codes are sometimes embedded in video descriptions or premiere streams. |
| Facebook page | Medium | Community posts and event announcements. Good backup if Discord is unavailable. |
| This page | Medium | Verified codes only—no unconfirmed or expired codes are mixed into the active list. |
