Why is my Upbit account locked or suspended?

Common Reasons for Upbit Account Suspension

1. Unusual login activity has been detected from unfamiliar devices or locations, triggering security protocols that temporarily lock access to protect user assets.

2. Failure to complete required identity verification steps, especially when attempting transactions above certain thresholds, may result in restricted functionality.

3. Suspected involvement in market manipulation tactics such as wash trading or spoofing can lead to immediate suspension pending investigation.

4. Repeated violations of Upbit’s terms of service, including API misuse or bot-driven high-frequency trading without authorization, often result in permanent account deactivation.

5. Linking wallets or addresses associated with illicit activities, such as those flagged by blockchain analytics firms, prompts automatic freezing of the linked account.

User Authentication and Compliance Issues

1. Incomplete KYC (Know Your Customer) documentation prevents full access; users must submit government-issued IDs and proof of residence to restore privileges.

2. Discrepancies in personal information across submissions—such as mismatched names or expired identification—cause delays in verification and trigger holds on withdrawals.

3. Attempts to change account details like phone numbers or email addresses without proper authentication may be interpreted as potential takeover attempts, leading to lockdowns.

4. Use of virtual private networks (VPNs) or proxy servers during login raises red flags due to perceived attempts to obscure geographical origin, especially from restricted jurisdictions.

5. Sudden spikes in transaction volume inconsistent with historical behavior prompt automated reviews under anti-money laundering (AML) policies.

Security Triggers and Risk Management

1. Multiple failed login attempts within a short timeframe activate protective measures designed to prevent brute-force attacks.

2. Withdrawal requests sent to newly added external addresses are often subject to mandatory cooling-off periods; bypassing these safeguards results in temporary locks.

4. Devices infected with malware that inject malicious scripts into trading sessions can cause unintended actions, which Upbit's system interprets as compromised credentials.

5. Sharing account access or using third-party trading tools not approved by Upbit violates security policies and increases the likelihood of suspension.
