Redeem a One Piece Bounty Rush promotion code through the official Bandai Namco Web Store, not through an in-game text box. Link your game to a Bandai Namco ID, sign in to the store with that same ID, open Enter Promotion Code, submit the code, and then return to the game’s Home screen. Rainbow Diamonds are claimed on Home; other rewards may be delivered to the Gift Box.

No active public code was verified in the official material checked on October 13, 2026. Codes are campaign rewards, and store offers can change by region, account and date, so treat every code or free-diamond listing as temporary until it appears in the official channels.

The exact redemption route

  1. Link the game account. In One Piece Bounty Rush, open the menu and data/settings area, then choose the Bandai Namco ID linking option described in the official Web Store guide: Bandai Namco’s Bounty Rush Web Store guide.
  2. Open the official store. Go to the global Bounty Rush Web Store and sign in with the same Bandai Namco ID that is linked in the game. Check the account identity before continuing.
  3. Open the code page. Select Enter Promotion Code. The store may label this as the promotion-code input screen; the dedicated page is ONE PIECE Bounty Rush — Promo Code.
  4. Type the code exactly. Do not add spaces or alter capitalization. The store warns that characters can look alike, including O/0, I/l/1, S/5 and B/8.
  5. Submit, then open the game. Return to Bounty Rush and open the Home screen. Rainbow Diamonds are automatically claimed there. Other items may be placed in the Gift Box, where an expiry deadline can apply.

This route is the only code-redemption method established by the official instructions. The existence of a code-entry page does not mean a public code is active today.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

What is confirmed about codes and free Rainbow Diamonds

Bandai Namco says promotion codes are distributed through campaigns and events. Its Bounty Rush guide says codes will be announced during future live broadcasts and other promotion campaigns; the Web Store information page likewise says codes can be obtained through various campaigns and events. Follow official Bounty Rush announcements and the Web Store rather than copying strings from unverified code lists.

When the official global store was checked on October 13, 2026, it displayed a free x50 Rainbow Diamonds offer and a monthly free x5 Rainbow Diamonds offer. The x50 item used a “Receipt Confirmation” flow. These were live-store observations, not permanent entitlements. Availability can differ by region or account and can disappear without notice.

Store item observed How it was presented Qualification
Free x50 Rainbow Diamonds Receipt Confirmation Visible in the global store snapshot checked October 13, 2026; verify the current listing before claiming.
Free x5 Rainbow Diamonds Monthly offer The listing stated that it refreshes monthly; the quantity and eligibility should be checked in the live store.
Timed listing Offer with an end time One listing shown in the snapshot ended October 13, 2026, at 13:59:59 UTC+09:00 (04:59:59 UTC), so it was already expired at the research timestamp.

Open the live store immediately before relying on an offer. Do not describe an expired or region-limited item as a currently available reward.

Before you enter a code

Use the game account that should receive the reward

The Web Store sends items to the game account associated with the Bandai Namco ID used to sign in. If you have more than one Bounty Rush account, sign out and confirm the correct ID before submitting anything. A successful submission on the wrong ID may deliver the reward elsewhere.

Confirm the account link in the game

Open the in-game menu, enter the data or account-settings section, and inspect the Bandai Namco ID link status. If the game is not linked, complete that link first. The store and the game must use the same ID; using a different store login is the most common way to make a valid reward appear to be missing.

Have the correct regional store

The Web Store can show different inventory by region, account and date. Use the official global store address supplied above, then check that the displayed game account and offer region match your installation. A code announced for one campaign or territory may not be eligible elsewhere.

Understand what you are redeeming

A promotion code and a free store listing are separate paths. A code is entered on the promotion-code page. A direct free listing is selected from the store catalog and may use receipt confirmation instead of a code. Do not paste a catalog item name into the code field or assume that every free item has a public code.

Step-by-step: linking Bounty Rush to a Bandai Namco ID

  1. Launch One Piece Bounty Rush and wait for the title or Home screen to load.
  2. Open the game menu and choose the data/settings option.
  3. Select the Bandai Namco ID link command. The exact surrounding menu wording can vary with the game version, but the official Web Store guide identifies the data-settings route.
  4. Sign in to an existing Bandai Namco ID, or create one through the official account flow if you do not already have one.
  5. Return to the game and verify that the link is shown as complete before opening the Web Store.

Do not switch to a second Bandai Namco ID between this step and redemption. If you later move game data to another platform, the Web Store information warns that owned Rainbow Diamonds can be lost; consider the platform decision carefully before transferring data.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Step-by-step: redeeming a promotion code in the Web Store

  1. Close or minimize the game and open the official Bounty Rush Web Store.
  2. Sign in with the Bandai Namco ID you just verified in the game. If the store displays an account selector, choose the account linked to your Bounty Rush data.
  3. Choose Enter Promotion Code. If you arrive at a general catalog page, open the store’s promotion-code option or use the official code page.
  4. Copy the code from the official campaign announcement when possible. If you type it manually, compare each character against the announcement. Pay special attention to O versus 0, I versus lowercase l or 1, S versus 5, and B versus 8.
  5. Submit once. Repeated submissions will not make an expired, already-used or ineligible code valid, and can make troubleshooting harder.
  6. Read the result message. A confirmation means the store accepted the request; an error normally indicates an invalid, expired, already-redeemed or region/account-ineligible code.
  7. Open Bounty Rush and go to Home. The official flow says Rainbow Diamonds are claimed there automatically.
  8. Open the Gift Box and inspect it for non-diamond rewards. Claim time-limited items before the deadline shown in the Gift Box.

How to claim a free Web Store offer without a code

Some free Rainbow Diamond items are catalog offers rather than promotion codes. The store snapshot showed a free x50 item and a monthly free x5 item. To check for one:

  1. Sign in to the official store with the linked Bandai Namco ID.
  2. Review the Bounty Rush catalog for an item explicitly marked free. Read the quantity, refresh period, region and any end date.
  3. Open the item and follow the displayed receipt-confirmation or claim control. Do not enter payment details for an item that is clearly labeled free.
  4. Return to the game Home screen to receive Rainbow Diamonds. Check the Gift Box as well if the item description says that additional rewards are delivered there.

A monthly label describes the store’s refresh schedule, not a guarantee that every account sees the item every month. If an offer is absent, the account, region, campaign window or eligibility may differ.

Where the reward appears

Reward type Where to look first What to know
Rainbow Diamonds from the official redemption flow Game Home screen The instructions say they are automatically claimed when you return to Home.
Other promotion or store items Gift Box Some items are delivered there and may have a claim deadline.
Purchased Rainbow Diamonds The purchasing platform The official FAQ says purchased Rainbow Diamonds are displayed and usable only on the platform where the purchase was made: Bandai Namco’s Rainbow Diamond FAQ.
Some Multi-Login gifts Gift Box claim choice The FAQ describes a “Claim Through Mobile” or “Claim Through Steam” choice for a Present Box gift when Multi-Login is enabled.

The platform rule above is specifically documented for purchased Rainbow Diamonds. It should not be expanded into a claim that every promotion-code reward transfers between mobile and Steam. The reviewed FAQ does not settle the behavior of every promotional reward.

Troubleshooting a missing or rejected reward

The code says invalid or expired

  • Recheck O/0, I/l/1, S/5 and B/8, then submit the exact campaign string again.
  • Confirm that the campaign is official and that its end date has not passed.
  • Check regional restrictions and whether the code was limited to one redemption per account.
  • Do not substitute a code copied from a third-party list for the string in the official announcement.

The store accepted the code, but no Rainbow Diamonds appear

  1. Return to the game Home screen; that is where the official instructions say Rainbow Diamonds are claimed.
  2. If nothing changes, restart the app and open Home again.
  3. Verify that the Bandai Namco ID in the store is exactly the one linked in the game.
  4. Check the Gift Box for other reward items and read any deadline.

The item went to another account

This usually means the store session used a different Bandai Namco ID from the game. Sign out of the Web Store, sign back in with the linked ID, and verify the in-game link before trying another eligible offer. Do not repeatedly redeem a one-time code while investigating.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The platform changed

If you moved game data between platforms, the Web Store information warns that owned Rainbow Diamonds can be lost. For a purchase-specific mismatch, use the support route in the official FAQ. Keep the platform distinction narrow: the documented purchased-diamond rule does not prove how every free or promotional item behaves after a transfer.

A Gift Box reward disappeared

Some Gift Box items have deadlines. Open the Gift Box promptly after redemption and claim anything with an expiry timer. A missed deadline may not be recoverable through another code submission.

How to find legitimate future codes

There is no verified public code to list here. Bandai Namco’s own wording points to live broadcasts, campaigns and events as the distribution channels. Monitor official Bounty Rush announcements and the Web Store’s promotion area. A page that merely contains a code input box is not evidence that a working code exists.

Before using a code, check four details in the official announcement:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • the exact character string, including capitalization;
  • the eligible region, platform or account type;
  • the start and end time, including the time zone;
  • whether the code is single-use, account-limited or tied to a particular event.

Avoid pages that demand your Bandai Namco password, ask you to install an unknown app, or promise unlimited Rainbow Diamonds. The official redemption flow requires the Web Store login and code submission; it does not require a physical game edition, printed code card, accessory or other merchandise.

Code redemption versus direct free offers

Question Promotion code Direct free Web Store offer
Where do you start? Enter Promotion Code page Store catalog listing
How is eligibility established? Campaign code, region and expiry rules Live account, region and listing availability
What should you inspect? Character accuracy and campaign terms Quantity, refresh period and end date
Where do Rainbow Diamonds appear? Game Home screen after submission Game Home screen after the store claim
Where might other items appear? Gift Box Gift Box, if the listing specifies it

Both routes require the same basic safeguard: the Web Store account must match the Bandai Namco ID linked to the game.

Practical checklist

  • Install and launch the current One Piece Bounty Rush app.
  • Link the correct game account to a Bandai Namco ID through the game’s data/settings menu.
  • Open the official Web Store and confirm the same ID is signed in.
  • Use Enter Promotion Code only for a genuine campaign code.
  • Check confusing characters before submission.
  • Read region, expiry and account-limit terms.
  • Return to Home to claim Rainbow Diamonds.
  • Inspect the Gift Box for other items and deadlines.
  • For purchases, remember the platform-specific rule documented by Bandai Namco; do not assume every promotional reward transfers across platforms.

Official pages

The Bottom Line

Use the official Web Store with the Bandai Namco ID linked to your game, enter only codes announced through official campaigns, and return to the Home screen to collect Rainbow Diamonds. Because codes and free offers expire or vary by region and account, verify the live listing each time rather than relying on an old code list.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
