The only active free Diamond code for Idol Party in March 2026 is IT7BQGSC1V — expires March 12, confirmed working by community testing. Six February codes are already dead. Beyond this code, the White Day event (March 6–22) offers up to 1,000 locked Diamonds, and your monthly missions, dailies, and achievement backlog can push your total to 600+ Diamonds before March 31. Here's how to claim everything before it's gone.
Active Free Codes – March 2026
Redeem IT7BQGSC1V immediately. It expires March 12, and codes occasionally hit redemption caps before their listed date.
That's the complete list. Any site claiming five or six working March codes is recycling expired entries.
Expired Codes (February 28, 2026)
All six are dead. If you see these on a working codes roundup, treat the entire page as unreliable:

One code per account. No workarounds exist server-side.
Why Your Code Isn't Working
Three reasons cover 95% of failures:
Wrong server — your User ID (7–10 digits, Profile > Personal Info) is tied to a specific server. Confirm you're on Idol School, Shining Star, South East Asia Global 1001, or Middle East 1002 as appropriate.
Case error — IT7BQGSC1V must be all caps. One lowercase letter breaks it.
Already redeemed — one use per account. A secondary account claim blocks your main.
Where to Find New Codes First
Official channels drop codes first. The gap between an official release and community aggregation is usually under an hour — but that hour matters when caps exist.
Follow LONGYOU TECHNOLOGY's official social accounts directly. Developer livestreams and milestone events are the most reliable sources. The in-game announcement board and mail system also carry maintenance compensation codes — the March 5 server maintenance (10:00–11:00 GMT+8) before White Day is exactly the kind of event that generates them.
For community hubs: cross-reference any code against at least two independent sources. No expiry dates listed? No expired-code disclosure? Skip the whole page. The official Idol Party wiki and verified Discord servers are trustworthy. Random SEO blogs are not.
The March 31 Reset: What You Lose vs. What Carries Over
Most guides treat the reset as one event. It's not — it's several overlapping systems with different deadlines. Getting this wrong costs real Diamonds.
What Resets
Monthly missions reset hard at server midnight on March 31. Unclaimed rewards disappear with zero notification. This is the single most common source of lost free currency in the game.
Weekly missions run on their own schedule and are separate — if your weekly reset falls March 30 or 31, that's an additional deadline to track.
White Day event currency and the limited shop close March 22 at 23:59 UTC — earlier than the monthly reset, and the deadline most players miss. The limited SSR support banner also closes March 22.
Idol ranking resets follow their own cycle, not necessarily March 31 — check the in-game timer for your server.
The Pity Counter — Honest Answer
Pity does not reset with the monthly calendar. Community testing confirms your counter on a limited banner persists until that banner ends. But pity does not carry between limited banners. When the March 13–22 limited SSR support banner closes, any pity built on it is gone. Community consensus: pity resets to zero when a new limited banner launches, so March progress won't help you in April.
Locked Diamonds from events and codes count toward pity on eligible limited banners. The developer hasn't explicitly confirmed exact behavior at banner transitions — that's the one genuine uncertainty here.
What Carries Over
Permanent (unlocked) Diamonds in your wallet
All idol cards and roster progress
Achievement Gallery progress (unclaimed rewards don't notify you — more below)
Login streak, provided you don't miss a day
Pre-Reset Checklist: Two Deadlines, Not One
Before March 22 (White Day Deadline)
✅ Redeem IT7BQGSC1V — expires March 12
✅ Complete White Day participation for at minimum 100 locked Diamonds (F2P achievable)
✅ Target the Consolation tier (888 locked Diamonds) — community confirms this is realistic for active F2P players
✅ Decide on the March 13–22 limited SSR banner before it closes
✅ Spend all White Day event currency before 23:59 UTC March 22
March 25–31 Countdown
March 25–27: Audit monthly mission progress. Prioritize one-time missions — they don't refresh, so every incomplete one is a permanent loss.
March 28–29: Push any idol ranking tier you're close to. The gap between tiers matters more in the final days when everyone else is grinding too.
March 30: Open your Achievement Gallery and scroll every category manually. No notifications fire for newly completed milestones. One audit can surface 50–200 Diamonds you didn't know were sitting there.
March 31 (30 minutes before server midnight): Claim all monthly mission rewards. Set an alarm. No grace period exists.
Every Free Diamond Source in March 2026
Community data puts the realistic F2P monthly range at 300–600 Diamonds. Here's the breakdown:
New accounts get an additional 600+ Diamonds from first-month achievements — a one-time boost veterans don't have access to.
Don't Break Your Login Streak
Streaks reset to Day 1 if you miss even one day. The Diamond peaks at Day 7, 14, and 28 are disproportionately valuable. Set an alarm 30 minutes before your server's midnight reset — a 10-second login is enough. Missing Day 27 to reset on Day 28 is one of the most painful avoidable losses in the game.
Stack Events with Daily Missions
Most players ignore this. Many White Day actions — gifting, affection interactions, stage completions — also satisfy daily mission requirements. Do them in the right order and you're earning event rewards and daily mission Diamonds from the same action. Two minutes each morning mapping your daily list against the event task list can effectively double your Diamond yield per session.
Check the Achievement Gallery Weekly
Don't wait until March 30. The gallery pushes zero notifications for completed milestones, so players routinely sit on unclaimed rewards for weeks. Categories to audit: social achievements, stage completion milestones, idol affection thresholds, cumulative login counts.
Save or Spend? Banner Strategy for March
The March 13–22 limited SSR support banner is a real decision point. Here's the framework:
Pull if: You're within 1,500 Diamonds of hard pity (4,480 Diamonds), you need the support idol for your main team, or you've already lost your 50/50 — meaning your next SSR is guaranteed on rate-up. Worst-case for a full limited SSR is 8,960 Diamonds (two pity cycles), so knowing your position matters.
Skip if: You're F2P with under 1,500 Diamonds and no existing pity on this banner. It closes March 22, and whatever pity you build won't carry to April. You'd be spending for low-probability pulls with no safety net carryover.
Soft pity is worth understanding: community testing shows SSR rates increase meaningfully between pulls 20–28 (approaching hard pity at 28 pulls / 4,480 Diamonds). If you're in that window, the math shifts toward pulling.
The most common Diamond-wasting mistake: pulling on standard banners during a limited event. Standard banner pulls build pity on the standard pool — completely separate from your limited banner guarantee. They don't contribute to your limited SSR at all.
For players close to soft pity who want to close the gap before March 22, you can buy Idol Party Diamonds top up online — particularly useful when a small top-up would push you to a guaranteed SSR.
Topping Up Safely
If you're sitting at 3,000 Diamonds with a 50/50 guarantee banked heading into March 20, a top-up makes clear mathematical sense before the banner closes. The recharge Idol Party Diamonds cheapest price option through BitTopup offers competitive bundle pricing with fast delivery. Check your account's top-up history first — the first-time bonus meaningfully increases yield, so use it when you have a specific pull target, not speculatively.
One firm warning: avoid any site claiming to generate free Diamonds through hacks or generators. Diamond currency is server-side. No client tool can create it. These generators exist to harvest account credentials, nothing else. Legitimate sources are missions, events, codes, and official top-ups — full stop.
Frequently Asked Questions
What are the active free codes for March 2026? Only one: IT7BQGSC1V, valid until March 12. All February codes expired February 28.
How do I redeem a code? Profile icon → Gift Code → enter code (all caps, case-sensitive) → Redeem. Diamonds credit instantly. One use per account.
Does pity reset on March 31? No. Pity resets when a limited banner ends, not when the month ends. The March 13–22 banner's pity resets March 22. It won't carry to April's banner. Your permanent Diamond wallet is unaffected.
What happens to unclaimed monthly mission rewards after March 31? They're gone. No grace period, no notification. Claim everything before server midnight on March 31.
How many free Diamonds can I realistically earn per month? 300–600 from regular sources. New accounts add 600+ from first-month achievements. Full F2P hard pity (4,480 Diamonds) takes 7–15 months from scratch.
Where does Idol Party officially release new codes? LONGYOU TECHNOLOGY's official social accounts, developer livestreams, milestone events, and the in-game announcement board and mail system. Third-party aggregators are only as reliable as their sourcing from these channels.
Should I pull the March 13–22 limited SSR banner or save for April? Pull if you're near pity or have a 50/50 guarantee banked. Skip if you're F2P with under 1,500 Diamonds and no existing pity — low-count pulls are high-risk with zero carryover to April.
March 2026 stacks a maintenance window, White Day, a limited SSR banner, and a monthly reset into 26 days. The players who come out ahead treat March 22 and March 31 as two separate deadlines. Redeem IT7BQGSC1V today, map your White Day participation tier, audit your Achievement Gallery before the 31st, and make your banner decision with full pity context. Everything else is optimization on top of that.
