TL;DR
BatChat login failures (蝙蝠聊天登录失败) usually stem from six causes: incorrect phone number entry, expired or mistyped verification code, account suspension or ban, outdated app version, server synchronization issues, or device registration conflicts. The fastest path to resolution: verify your phone number with the correct country code, request a fresh verification code and enter it within the validity window, update the app to the latest version from batchat.com, and try logging in on a different device to isolate whether the issue is device-specific. If all else fails, contact support at support@batchat.com.
Understanding BatChat’s Login System
BatChat uses phone number-based authentication — there are no email logins, social media logins, or username/password combinations. Your phone number is your identity on the platform. The login flow works like this:
- You enter your phone number (with country code)
- BatChat sends a 6-digit SMS verification code
- You enter the code
- The app authenticates using the SRP (Secure Remote Password) protocol — your password-equivalent is never transmitted
- If you have an unlock password (解锁密码) configured, you must pass that biometric or PIN check before accessing messages
A login failure can occur at any of these stages. The error message you see helps narrow down which stage is failing.
Quick Diagnosis Table
| Error Behavior | Likely Cause | Priority Fix |
|---|---|---|
| ”Verification code incorrect” | Mistyped code or expired code | Request a new code and enter it carefully |
| ”Verification code expired” | Waited too long after receiving the code | Request a new one immediately |
| No code arrives at all | Carrier blocking, VoIP number, or server delay | See our verification code troubleshooting guide |
| ”Account does not exist” | Wrong country code or wrong number | Verify the country code and number format |
| ”Account has been restricted” | Account suspended or banned | Contact support |
| App crashes on login | Corrupted app data or outdated version | Clear app cache, update, or reinstall |
| Login works on phone but not PC | Device sync issue or outdated desktop version | Update desktop app, re-link device |
| Stuck on loading after entering code | Server sync delay | Wait 30 seconds, force-close and retry |
Fix 1: Verify Your Phone Number and Country Code
The single most common cause of login failure is an incorrect phone number or country code combination. This is especially common for users who travel internationally or have recently changed carriers.
Step 1: Confirm your country code is correct. BatChat defaults to +86 (China). If you’re outside China, tap the country code dropdown and select your actual country. Common mistakes:
- Using +86 when your number is registered under a different country code
- Including the leading zero of your subscriber number (e.g., entering 0138-xxxx instead of 138-xxxx)
- Adding extra digits like area codes
Step 2: Enter your phone number in international format. The correct format is: country code + subscriber number, with no spaces, dashes, or parentheses. Examples:
- China: +86 13800138000 → enter
13800138000with country code +86 selected - United States: +1 4155551234 → enter
4155551234with country code +1 selected - United Kingdom: +44 7911123456 → enter
7911123456with country code +44 selected (drop the leading 0)
Step 3: Double-check by having someone call the number you entered. If the call doesn’t reach you, the number is wrong.
Important: BatChat does not allow you to change your registered phone number within the app. If you’ve lost access to your original number, you must contact support for account recovery.
Fix 2: Handle Verification Code Problems
The 6-digit verification code (验证码) is the core of BatChat’s login process. Problems here fall into three categories.
Code Arrives But Doesn’t Work
Step 1: Check that you’re entering the most recent code. If you requested multiple codes, only the latest one is valid.
Step 2: Enter all 6 digits without spaces or dashes.
Step 3: Check for typos. The code is numeric only (0-9). If you see letters on your keyboard, make sure you haven’t accidentally switched to an alphabetic input.
Step 4: Verify the code hasn’t expired. BatChat’s verification codes have a limited validity window (typically 5-10 minutes). If you waited too long, the code becomes invalid. Request a new one.
Code Doesn’t Arrive
This is a separate issue covered in detail in our verification code troubleshooting guide. Quick steps:
- Check your phone has signal and can receive other SMS
- Wait the full 2 minutes — codes usually arrive within 30 seconds but can take longer during peak hours
- Check your spam/junk SMS folder (some phones filter automated SMS)
- Don’t request codes too rapidly — there’s a cooldown timer between requests
- VoIP numbers (Google Voice, TextNow, etc.) may not receive BatChat’s SMS
Code Works But Login Still Fails
If the code is accepted but you get stuck on a loading screen or an error after entering it:
Step 1: Wait at least 30 seconds. Server-side authentication can take a moment during high traffic.
Step 2: Force-close the app completely and reopen it.
Step 3: Check your internet connection. The app needs to communicate with BatChat’s servers after verifying the code.
Step 4: If the problem persists across attempts, clear the app cache (Android: Settings > Apps > BatChat > Storage > Clear Cache) or offload the app (iOS: Settings > General > iPhone Storage > BatChat > Offload App).
Fix 3: Resolve Account Restriction or Ban
BatChat can restrict or ban accounts that violate the platform’s terms of service. If you see a message indicating your account is restricted (账号受限) or banned (账号封禁), here’s what to do.
Possible reasons for restriction:
- Sending spam messages or unsolicited content to multiple users
- Reported by other users for harassment
- Using modified or unofficial versions of the BatChat app
- Automated behavior detected (bot-like activity)
- Violating Chinese telecommunications regulations
Step 1: Review whether any of the above applies. If you believe the restriction is in error, proceed to Step 2.
Step 2: Contact BatChat support to request a review:
- Email: support@batchat.com
- Phone: +86-28-85189556 (business hours, UTC+8)
- WeChat: Follow “蝙蝠密聊” for official support channels
Step 3: Provide your phone number (with country code) and a clear explanation of why you believe the restriction should be lifted.
Step 4: Wait for support response. Response times vary, but typically you’ll hear back within 1-3 business days.
Important: Do not create a new account with a different number to circumvent a ban. BatChat can detect this and may ban the new account as well. Work through the official support channels.
Fix 4: Update Your App Version
Running an outdated version of BatChat can cause login failures because older versions may use deprecated authentication protocols or incompatible server endpoints. This is especially common after BatChat releases a major update.
How to check your current version:
- Open BatChat > Settings (设置) > About (关于) — the version number is displayed at the top
How to update:
Android
Since BatChat isn’t distributed through Google Play in most regions, updates aren’t automatic.
- Open your phone’s browser
- Go to batchat.com
- Tap Android下载 to download the latest APK
- Install the new version (it will overwrite the old one; your data is preserved)
- Open the updated app and try logging in again
iOS
- Open the App Store
- Search for “蝙蝠聊天” or “BatChat”
- If an “Update” button appears, tap it
- After the update completes, open BatChat and try logging in
Windows PC
- Open batchat.com in your browser
- Click PC版 to download the latest installer
- Run the installer — it will update your existing installation
- Restart BatChat
macOS
- Open batchat.com
- Click Mac版 to download the latest version
- Install and replace the previous version
Current version as of this writing: v3.4.5 (check batchat.com for the latest)
Fix 5: Resolve Device Registration Conflicts
BatChat ties your account to specific devices. In some situations, device registration data can become corrupted or conflict with existing registrations.
Scenario 1: Switching to a new phone
When you get a new phone and install BatChat, you log in with the same phone number and verification code. The app creates a new device entry. If the old device is still active, both can work simultaneously. However, if the transfer was incomplete, the new device may fail to sync properly.
Fix: On the old device, open BatChat and go to Settings > Device Management (设备管理) and remove the old device registration. Then log in fresh on the new device.
Scenario 2: Multiple failed login attempts
Repeated failed login attempts can trigger a temporary lock on your account for security purposes. This is similar to how banks lock your card after too many wrong PIN entries.
Fix: Wait 15-30 minutes before trying again. During this window, do not attempt to log in. After the cooldown, request a fresh verification code and try once.
Scenario 3: Corrupted local data
If the app’s local database is corrupted, it can prevent successful login even when your credentials are correct. This is common after a forced shutdown, storage error, or incomplete app update.
Fix:
Android:
- Settings > Apps > BatChat > Storage
- Tap Clear Cache first (try logging in again)
- If that fails, tap Clear Data (this removes local chat history but not your account)
- Open BatChat and log in normally
iOS:
- Settings > General > iPhone Storage > BatChat
- Tap Offload App (preserves your data but removes the app)
- Tap Reinstall App
- Log in normally
Windows:
- Close BatChat completely
- Navigate to
%AppData%\BatChat\in File Explorer - Delete or rename the
Cachefolder - Restart BatChat
macOS:
- Close BatChat (Cmd+Q)
- Open Finder, press Cmd+Shift+G
- Navigate to
~/Library/Application Support/BatChat/ - Delete the
Cachefolder - Restart BatChat
Fix 6: Server Synchronization Issues
Occasionally, BatChat’s authentication servers experience synchronization delays. This is most common during:
- Peak usage hours (evenings in China, UTC+8)
- Immediately after a major app update
- During partial server maintenance
Symptoms: You enter a correct verification code, the app shows a loading spinner for an extended period, then displays an error.
Fix:
- Wait 30 seconds to 1 minute — the server may still be processing
- Force-close the app and retry the login flow from the beginning
- If it fails repeatedly, wait 10-15 minutes and try again
- Check the official WeChat account “蝙蝠密聊” for any announced server issues
Login vs. Unlock Password: Know the Difference
A common source of confusion: users sometimes confuse a login failure with an unlock password failure.
-
Login failure happens when you first open the app and enter your phone number + verification code. This is about proving you own the account.
-
Unlock password failure (解锁密码失败) happens after you’ve logged in successfully but the app asks for your face, fingerprint, or PIN before showing your messages. This is the secondary security layer.
If you’re stuck at the unlock password screen:
- Try each method you have configured (face, fingerprint, and PIN)
- If you forgot your PIN, look for a “Forgot password” or “Use verification code” option on the unlock screen
- On some devices, repeatedly failing the unlock password prompts you to verify via SMS again
- As a last resort, uninstall and reinstall the app — you’ll go through the full login flow again

Frequently Asked Questions
Can I log into BatChat with an email address?
No. BatChat only supports phone number-based authentication. Your phone number is your unique account identifier. There is no email login, social media login, or username/password option.
What happens if I lose my phone number?
Contact BatChat support at support@batchat.com immediately. Provide your old phone number and any identifying information. Account recovery without the original number is handled case-by-case and may require additional verification. This is one of the risks of phone-based authentication — keep your number active.
Why does my verification code keep saying it’s wrong?
The most likely causes: you’re entering an old code (request a new one), there’s a typo (enter slowly and carefully), or you’re waiting too long and the code expires (codes are valid for 5-10 minutes). Make sure you’re looking at the most recent SMS.
Can I use BatChat on two phones simultaneously?
Yes. BatChat supports multi-device login. You can log in with the same phone number on multiple devices. Each device generates its own encryption keys. Note that messages received on one device may not appear on others if they were offline at the time — the server relays messages to connected devices only.
Why does BatChat say my account is restricted after I just registered?
New accounts that immediately send messages to many users or exhibit automated behavior can trigger BatChat’s anti-spam system. If you believe this is in error, contact support. Otherwise, wait a few hours and try again — restrictions on new accounts are sometimes temporary.
How do I change my registered phone number on BatChat?
BatChat does not currently offer in-app phone number changes. If you need to switch numbers, contact support@batchat.com with both your old and new numbers. They can process the change on their end. Keep your old number active until the transfer is confirmed.
