The MyCard TW Spring 2026 campaign runs February 9 to April 9, 2026 (midnight TST, UTC+8). If you're reading this in April, you're in the last stretch. The three MLBB codes (2y3vo2r3x,0nc9lhok9,3r83efok9) almost certainly expired by early March — but the 30% top-up bonus tiers and ToS spring rewards are still live through April 9. Here's what's still redeemable, how to get it, and what kills your redemption before you even start.
Why Codes Expire Before the Campaign Does
This is the part most guides skip. The April 9 deadline applies to the campaign — not every code inside it.
MyCard TW staggers expiry windows by code type. The MLBB serial codes were set to expire 2–4 weeks after February 9, putting their cutoff somewhere between February 23 and March 9. The top-up bonus tiers run the full campaign. ToS spring event rewards are claimable through April 9, but the event itself closed March 15.
Also worth knowing: April 9 midnight TST is April 8 at 4:00 PM GMT+0. PTT community members have reported failed redemptions from assuming April 9 meant their local midnight. It doesn't. The cutoff is server-side.
What's Still Active in April 2026
The MLBB codes are almost certainly dead. But if you received a physical card or bundle after February 9, try them immediately — some purchase-date-tied codes carry extended validity windows.
MLBB Code Breakdown
2y3vo2r3x— ~37 diamonds0nc9lhok9— ~37 diamonds3r83efok9— ~38 diamondsTotal: 112 diamonds, single-use per account
In April, these will return expired or invalid — not already used. That distinction matters for troubleshooting (see below).
Community-Reported Codes
No additional verified codes beyond the three MLBB serials have been confirmed through official channels. PTT reports suggest bonus vouchers were distributed via MyCard TW LINE notifications to verified members — but those are account-specific, not universal. If you got a LINE message from the official MyCard TW account, check it now.
Official sources only: mycard.com.tw, the official MyCard Facebook page, and in-game event banners. PTT's MyCard board aggregates community reports but isn't official — cross-check everything.
How to Redeem: Three Methods
Method 1: Web Portal — Game Serial Codes
Log in at pay.mycard.com.tw
Go to 序號兌換 (code redemption)
Enter the code exactly — case-sensitive, all lowercase for MLBB codes
Select your game and enter your in-game member ID
Confirm and submit
Diamonds appear within 5–15 minutes. If nothing after 30 minutes, check your MyCard Member Center for pending reward status before contacting support.
Method 2: In-Game Redemption (MLBB)
Go to Events → Redeem Code inside MLBB. Faster than the web portal and bypasses it entirely. New accounts may need 5–10 matches played before the redemption option unlocks — not officially documented, but consistently reported by the community.
Method 3: Top-Up Bonuses
These aren't codes. They apply automatically when you top up at qualifying amounts through the MyCard Payment Center. Hit TWD 3000 in a single transaction and the 30% bonus triggers — provided your account has full identity verification completed (name, national ID, date of birth, email, mobile, address, 2FA OTP, and 6-digit payment password).
Account Prerequisites
✅ MyCard TW member account active (zero-balance accounts inactive 6+ months may be terminated)
✅ Identity verification complete for TWD 3000 tier access
✅ 2FA enabled — mandatory as of Q1 2026, every login requires OTP
✅ Game account on the Taiwan server — MyCard TW is region-locked to TW-server accounts, not your physical location
International players: your location doesn't matter. Your game server does. Non-TW server MLBB accounts can't use these codes or bonuses.
Top 5 Redemption Errors — Fixed
1. Code Already Used
Two distinct causes. Either someone with account access redeemed it, or the code was a shared promotional code that hit its global redemption cap across all players. Check your redemption history in the Member Center. If the code doesn't appear there, it was likely exhausted by other players — not used on your account. Contact support with your member ID and code to confirm, but recovery is unlikely either way.
2. Region Restriction — Overseas Players
The portal doesn't require a Taiwan IP to log in, but certain code types are flagged for Taiwan-region accounts. If you're abroad and hitting this error, disable your VPN first — VPNs sometimes trigger false region flags. If the error persists without a VPN, the code type may be restricted to accounts registered with a Taiwan address, which ties back to KYC verification.
3. Account Ineligible — Verification Gaps
The TWD 3000 tier requires complete verification. The most commonly missed field: the 6-digit payment password, which is separate from your login password. Go to mycard.com.tw → Account Settings → Identity Verification and confirm every field shows a green checkmark. Then check Security settings for 2FA.
4. Invalid Code Format — Copy-Paste Issues
Codes copied from PDFs or screenshots sometimes carry invisible characters. Type manually if copy-paste fails. Also: the MLBB codes use numeric zeros, not the letter O.0nc9lhok9 starts with zero.
5. Server Timeout During Submission
You hit submit, the page times out, and you don't know if the code was consumed. Don't resubmit immediately. Go to your Member Center and check redemption history. If the code appears there, it processed successfully even without a confirmation page. If it's absent after 10 minutes, the transaction failed cleanly and you can retry. Community advice: redeem on weekday mornings before 11AM TST to avoid peak-hour timeouts — especially critical in the final 48 hours before April 9.
Which Games Get the Best Return
MLBB and Lineage W offer the highest practical value. The 1:1 MLBB conversion with zero fees means every bonus diamond is a real diamond.
Stack Your Sources Before Topping Up
Before spending any TWD, exhaust free diamond sources first. MLBB missions yield 200–300 diamonds weekly, login bonuses add 50–80, and rank rewards range from 400 diamonds at Grandmaster to 1,000+ at Mythic. Collecting these first gives you 8–12 pity advances before you spend anything.
The 30% bonus also stacks with in-game events, the MLBB Weekly Diamond Pass, and 2–3% cashback from certain payment methods. The optimal stacking window was February 13–26 during the Task Master Lucky Draw — but the 30% bonus alone still applies through April 9.
The Single Transaction Rule
This is where players consistently leave diamonds on the table. Bonus tiers apply per individual transaction, not cumulatively. Three TWD 1,000 top-ups each get the 20–25% tier. One TWD 3,000 top-up gets 30%. Community math puts the difference at up to 500 additional diamonds for the same total spend. Always consolidate into the largest single transaction your budget allows.
For players planning a final top-up before the deadline, buy MyCard TW points discount spring campaign 2026 to lock in your balance efficiently before the April 9 cutoff.
Payment Timing in the Final 48 Hours
This matters more than most players realize. Bank transfers submitted after 3PM TST can take 1–24 hours to process. Cutting it close on April 8 with a bank transfer is genuinely risky. In the final 48 hours, use E-wallet, FPX, or EC Pay instead.
Minimums: FPX requires TWD 200, E-wallet/EC Pay requires TWD 300.
After topping up, verify your balance in the MyCard Payment Center before attempting in-game purchases. The 30% bonus diamonds should appear in your MLBB account within minutes of a confirmed top-up.
If you want your balance confirmed well before the server-side cutoff, MyCard TW cheap top up before April 2026 deadline is worth checking for fast delivery.
After April 9: What You Can and Can't Recover
Expired codes are gone. MyCard TW customer service has no override mechanism for promotional code expiry — once the server-side cutoff passes, the code returns permanent invalid status. What support can investigate: whether a code was incorrectly flagged as used when it wasn't, or whether a technical error prevented a valid redemption. If you have an error screenshot timestamped before April 9, that's your documentation for a dispute.
Rewards sitting in the MyCard Member Center — including ToS spring event rewards — must be manually claimed before April 9. They don't auto-credit. Log in and check your Member Center now if you've been earning ToS points since February 16.
Contact MyCard TW support at mycard.com.tw with your member ID, the code, and any error messages. Response times during campaign close periods run 2–5 business days.
FAQ
Where do I enter my MyCard TW promo code? Game serial codes go through pay.mycard.com.tw under 序號兌換, or directly in-game via Events → Redeem Code. Top-up bonuses aren't entered as codes — they apply automatically at qualifying transaction amounts.
When exactly do the April 2026 spring codes expire? Campaign closes April 9, 2026 at midnight TST (UTC+8) — that's April 8 at 4PM GMT+0. MLBB serial codes expired earlier, around February 23–March 9. ToS rewards are claimable through April 9, but the event closed March 15.
My code says already used but I haven't redeemed it. Why? Either someone with account access used it, or the shared code hit its global redemption cap. Check your Member Center redemption history. If the code isn't there, contact support — they can confirm whether it was redeemed on your account or exhausted globally.
Can I redeem from outside Taiwan? Yes, if your game account is on the Taiwan server. Disable any VPN before redeeming — VPNs can trigger false region restriction errors.
Which games benefit most from the spring bonus? MLBB, Tower of Saviors, Lineage W, Night Crows, and Three Kingdoms Clash of Heroes. MLBB and Lineage W offer the highest practical value given their diamond economies and the 1:1 MLBB conversion rate with no fees.
What happens if I don't claim my ToS rewards before April 9? They're forfeited. The ToS reward cap is 5 redemptions (3,750 points total), yielding 30 diamonds, 4,000 Souls, 40M Coins, and 5 Harpies if fully collected. Log in and claim now.
