Troubleshooting Guide

Redemption codes in Build a Blue Lock Squad provide free in-game rewards including currency, Character Shards, and exclusive items. When codes fail to work, the issue is usually one of several common causes. This guide covers every known code redemption problem and their solutions.

How Code Redemption Works

To redeem a code, navigate to the in-game Settings menu and select the Gift or Redemption option. Enter the code exactly as shown, including any hyphens or special characters. Press Confirm and wait for the server to process the request. Successful redemptions immediately add items to your inventory. Code redemption requires an active internet connection and a linked account. Guest accounts cannot redeem codes in most cases.## Common Code Redemption Issues

Issue: “Code Not Found”

The most common error message. This typically means the code was entered incorrectly or the code has already expired. Check for typos, ensure you copied the full code including any dashes, and verify the code is still within its redemption period. Expired codes cannot be redeemed. Each code has a specific validity window stated in its original announcement. Codes from limited-time events typically expire within 30 to 90 days of the announcement.

Issue: “Code Already Used”

This message indicates the code has been redeemed on your account previously. Each code can only be used once per account. Check your inventory to confirm the items were added. If you believe you have not used this code before, contact support with proof of purchase or the original code source. Some codes require a specific account level or story progress to redeem.

Issue: “Account Not Eligible”

Certain codes are region-locked or require specific conditions to redeem. Codes distributed through platform-specific events may only work on that platform. For example, codes from the iOS launch event will not work on Android accounts. Some codes require minimum account Level or story progress. New accounts created after the code announcement may not meet eligibility requirements.

Issue: “Server Maintenance”

Code redemption is sometimes disabled during scheduled maintenance windows. If the redemption page is unreachable or returns errors, check the official social media channels for maintenance announcements. Wait until maintenance ends and try again.

Issue: “Network Error”

Unstable internet connections can cause redemption failures. Switch to a more stable network connection, disable VPNs if active, and ensure your device’s date and time are set correctly. Incorrect system time can cause SSL certificate validation failures that block redemption requests.

Issue: “Code Format Incorrect”

Some codes use similar-looking characters that are easily confused. The letter O and the number 0 appear similar. The letter I and the number 1 can also look identical depending on the font. Always double-check that you are using letters where letters are required and numbers where numbers are required.## Platform-Specific Issues

iOS

Apple’s App Store review process sometimes delays code activation by up to 24 hours after an event announcement. If your code was announced during an Apple review period, wait before attempting redemption. iOS users must have a linked social account to redeem codes. Go to Settings, Account, and Link Account to connect before attempting redemption.

Android

Android devices may block redemption if Google Play Services are outdated. Update Google Play Services from the Play Store before attempting to redeem codes.

Console (PlayStation, Xbox, Switch)

Console redemption typically requires entering codes through the platform’s built-in browser rather than the in-game browser. Use the console’s official browser for reliable redemption.## Expired vs Invalid Codes There is a critical difference between expired and invalid codes. An expired code was valid at one time but has passed its redemption window. An invalid code never existed in the system. If you received a code from a third-party source, verify its origin. Only use codes from official Build a Blue Lock Squad channels: the official website, verified social media accounts, and official community events. Codes from unofficial sources may be fake, already used, or designed to steal account information. Never share your account credentials with anyone offering free codes.## How to Contact Support If you have tried all troubleshooting steps and your code still does not work, contact official support through the in-game Help menu. Provide the following information:

• The exact code you attempted to redeem
• The date and time of the attempt
• Screenshots of any error messages
• Your account ID or linked account email Support response times vary but typically range from 24 to 72 hours. Codes identified as valid but blocked by technical issues are usually resolved within one business day.## Preventing Future Code Issues Create a linked account immediately if you have not already. Guest accounts cannot recover codes or receive support for redemption issues. Link to an email address or a social platform like Google or Apple. Bookmark the official code announcement page and check it weekly. Many limited-time codes are announced without extensive promotion and can be missed easily. Enable notifications from official Build a Blue Lock Squad social media accounts so you never miss a code announcement.
