How to Open a Binance Sub-Account: Limits and Management Guide

Sub-accounts are standard for large-capital and multi-strategy users on Binance. To begin, log in to the Binance Official Website and use the Binance Official App (for iOS, see the iOS Installation Tutorial).

Uses for Sub-Accounts

Use Case	Benefit
Strategy Isolation	A failure in one strategy doesn't affect the others.
Team Permissions	Grant different access levels to employees or partners.
Position Independence	Each account has its own independent liquidation price.
Tax / Accounting	Separate reports for different accounts.
API Isolation	An API key issue only affects one specific sub-account.

Creating a Sub-Account

1. Access the Page

Go to Profile → Sub-Account on the main account. Note: Access may depend on your VIP level; VIP 0 users might not see this option.

2. Enter Email

Use a unique email address for the sub-account (it cannot conflict with the master account or other existing users).

3. Set Password

Create a unique password for the sub-account.

4. KYC Inheritance

Sub-accounts share the KYC verification of the master account; no additional identity verification is required.

5. Completion

The sub-account is created and ready for use immediately.

Sub-Account Limits

VIP Level	Sub-Account Limit
VIP 0–2	5–10
VIP 3+	50–200
Institutional	500+

Fund Management

Transferring from Master to Sub-Account

Go to the Sub-Account Management page → Transfer → Select target sub-account → Select asset and amount → Complete. Transfers are instant.

Transferring from Sub to Master Account

Sub-accounts cannot initiate transfers to the master account. The master account must "Withdraw" the funds from the sub-account.

Transferring Between Sub-Accounts

This must be done via the master account as a two-step process.

Permission Management

You can configure the following for each sub-account:

• Enable/Disable Spot Trading
• Enable/Disable Futures Trading
• Enable/Disable Margin Trading
• Enable/Disable Withdrawals
• Enable/Disable Lending
• API Creation Permissions

Most common setup: Disable withdrawals + Enable Futures.

KYC and VIP Level

Sub-accounts inherit the KYC and VIP level of the master account. Trading fees for all sub-accounts are calculated based on the master account's VIP status.

Limitations of Sub-Accounts

• Cannot withdraw funds independently (unless specifically enabled, and even then it follows the master KYC).
• Limited or no access to independent P2P/C2C trading in some scenarios.
• VIP status is strictly tied to the master account.

Strategy Isolation Example

Master Account: 1,000,000 USDT.

Sub-Account	Strategy	Allocation
Sub 1	Long-term BTC/ETH holding	30%
Sub 2	Spot Grid Trading	20%
Sub 3	Futures Strategy A	20%
Sub 4	Futures Strategy B	15%
Sub 5	Funding Rate Arbitrage	15%

Each sub-account has its own PnL (Profit and Loss) and independent liquidation boundaries.

Team Permissions

If you are an institution or a studio:

• Sub 1: Trader (Read-only)
• Sub 2: Trader (Order execution)
• Sub 3: Risk Control (Read-only)
• Sub 4: Finance (Transfer permissions)

Each sub-account can have its own independent login and 2FA.

Viewing Total Assets

The master account's Sub-Account Management page shows the combined assets of all sub-accounts. You can also see this in Assets → Overview → Include Sub-Accounts. APIs can also fetch balances for all sub-accounts.

Safety and Security

1. Independent 2FA: Bind a unique Authenticator to each sub-account so a breach in one doesn't compromise others.
2. Email Isolation: Use different emails to reduce the risk of linked attacks.
3. API Isolation: Keep API keys separate for each sub-account.
4. Disable Withdrawals: Keep sub-account withdrawal permissions off unless absolutely necessary.

Sub-Accounts and Copy Trading

You can use sub-accounts to follow different lead traders:

• Sub 1: Follow Lead Trader A.
• Sub 2: Follow Lead Trader B. This allows you to clearly see the performance of each lead trader in their respective PnL.

FAQ

Sub-accounts act as a "Risk Firewall" for large capital. If your trading volume exceeds 50,000 USDT, you should consider using them.
