No active codes right now. As of April 1, 2026, every recent code has expired — the last one, IT7BQGSC1V, died March 12 at 23:59 UTC. The February batch went out on the 28th. That said, spring update cycles historically bring new drops, and this page updates the moment anything goes live.
All Active Idol Party Diamonds Codes — April 2026
Current working codes: zero. Here's the full archive of what just expired, including exact rewards — useful for knowing what to expect when the next batch lands.
Transparency note: none of these carry official developer confirmation. IDOLPARTY2 has the highest confidence because its reward breakdown is specific and documented. The rest are community-reported with consistent ranges.
When new codes drop: prioritize IDOLPARTY2-style milestone codes first — 100 locked Diamonds beats the standard 20–80 range every time. Redeem within 24 hours. Some codes have global redemption caps and die before their listed expiry date, no warning given.
Codes Added This Week
None. This section updates immediately when LONGYOU TECHNOLOGY releases new codes via their official Discord (💖┊white-valentine and announcements channels), Steam page, or in-game notices.
How to Redeem Codes — Step by Step

Launch Idol Party Diamonds and reach the main lobby
Tap the Profile icon (top-left corner)
Select Gift Code from the menu
Enter your code — ALL CAPS, exactly as written
Tap Redeem
Use copy-paste. One lowercase letter kills the redemption — the system has zero tolerance for case errors.
Where Do Diamonds Appear After Redemption?
Sources conflict here. Some players see diamonds credit instantly to their balance; others find them sitting in the in-game mailbox waiting to be claimed. Both are normal. If your balance doesn't update, check the mailbox before assuming the code failed.
One edge case: redeeming within 15–30 minutes of server maintenance ending can trigger a false error. Don't panic — wait out the window and retry. This exact situation confused a chunk of the community after the March 5, 2026 maintenance (10:00–11:00 GMT+8).
How Many Diamonds Do Codes Actually Give?
The 20–80 range isn't vague — it reflects real variability based on account age, server, and event tier. You won't know your exact amount until you redeem.
February vs. March vs. April: February was the strongest month — six codes dropped simultaneously, with IDOLPARTY2 alone worth 100 locked Diamonds plus items. March delivered one code in the 20–80 range. April is at zero. Community patterns suggest codes cluster around holidays and patch milestones, so a spring update drop is plausible. Treat that as informed speculation until official channels confirm.
Expiry Dates — Don't Get Caught Out
Codes expire fast, and the listed time is always UTC. Convert before assuming you have runway.
The February 28 batch is the clearest example: players in UTC+8 had until March 1 at 07:59 local time — not midnight on the 28th. Missing that conversion cost people an entire code batch.
When April codes drop, treat the first 24 hours as your window regardless of the listed date. Global redemption caps can kill a code early with no announcement.
Code Not Working? Four Causes, Four Fixes
Community data points to the same four culprits almost every time.
1. Case error — Must be ALL CAPS. IDOLPARTY2 works. idolparty2 doesn't. Copy-paste from official sources.
2. Wrong server — Idol Party Diamonds runs on distinct servers: Idol School, Shining Star, South East Asia Global (1001), and Middle East (1002). Some codes are server-specific. Check your server under Profile > Personal Info — your UID (7–10 digits) is tied to one server only.

3. Already redeemed — One use per account, no exceptions. Redeemed on a shared device or alt? Gone permanently.
4. Expired — Check UTC, not local time. A 23:59 UTC expiry is 05:29 the next morning in UTC+5:30.
Post-maintenance errors are a fifth, less common cause. Wait 15–30 minutes after maintenance ends and retry before writing off a code as dead.
Where to Find New Codes First
Official Discord is the fastest source. LONGYOU TECHNOLOGY posts in the 💖┊white-valentine and announcements channels. Enable channel-specific notifications — general server alerts will bury the signal.
Steam page carries developer-confirmed announcements. Slightly slower than Discord but authoritative.
In-game News tab is reliable but requires you to be actively playing.
Community hubs (Reddit, fan Discords) aggregate codes quickly. Filter ruthlessly: only trust codes that link back to an official source. Community-reported codes without an official origin have a noticeably higher dead-on-arrival rate.
No fixed release schedule exists. Based on current data, codes cluster around holidays, game milestones, and patch releases. February's large batch tied to Valentine's/White Day season. March had one. The spring update window is the next logical cluster point.
Maximizing Diamonds in April 2026
Codes are a supplement. Here's the full F2P picture for the month.
Monthly Diamond Sources
The Achievement Gallery point is worth repeating: established players routinely sit on 50–200 unclaimed Diamonds there. Audit it weekly, not monthly.

The White Day 2026 Lesson
The March 6–22 event showed how much a single decision matters: the solo NPC submission path yielded 988 Diamonds versus 600 for the partnered route — a 65% difference. April events will likely carry similar branching choices. Before committing to any event path, check community discussion on which route maximizes Diamond output.
Locked Diamonds and Pity — The Misconception That Costs Players
This is officially confirmed and still widely misunderstood: locked Diamonds from codes advance limited banner pity identically to paid Diamonds. The belief that they don't is wrong, and it causes players to undervalue code rewards.
At 160 Diamonds per pull and hard pity at 28 pulls (4,480 total), even a 100 locked Diamond code represents real pity progress. Soft pity activates between pulls 20–28 — never abandon a banner once you're in that range. The sunk progress makes stopping mathematically costly.
The community-tested 70/30 rule: commit no more than 70% of your Diamond reserves to one banner, hold 30% back. Code Diamonds count toward this calculation the same as purchased ones.
If you're targeting a specific banner and the F2P math doesn't close the gap, Idol Party Diamonds cheap top up April 2026 through BitTopup offers competitive rates with fast delivery — worth checking if you're planning a pity push this month.
FAQ
Can I use the same code on multiple accounts? No. One use per account, no workaround. Global redemption caps also apply — some codes expire across all accounts before the listed date.
Do locked Diamonds count toward banner pity? Yes, officially confirmed. Locked Diamonds advance limited banner pity identically to paid Diamonds. This is one of the most persistent misconceptions in the community.
Will more codes drop in April 2026? Unconfirmed but plausible. Pattern analysis suggests spring update windows bring code clusters. Nothing announced as of April 1, 2026 — watch the official Discord and Steam page.
Why does my code say invalid when I typed it correctly? Four possibilities: expired, already redeemed on this account, case error (must be ALL CAPS), or wrong server. Post-maintenance false errors are also possible — wait 15–30 minutes and retry.
What should I spend code Diamonds on? Limited banners, using the 70/30 rule. Never stop pulling once you've entered soft pity range (pulls 20–28) — that progress is sunk and stopping is a net loss.
Where's the fastest place to catch new codes? Official Discord, specifically the 💖┊white-valentine and announcements channels with channel-specific notifications enabled.
