Phishing emails are one of the most common attack methods in the cryptocurrency space. Scammers send fake emails nearly identical to official Binance emails, luring you into clicking malicious links or revealing account information. Binance offers the "Anti-Phishing Code" feature specifically for this purpose -- a simple but extremely effective security tool. Once set up, every official Binance email will contain your custom identifier, allowing you to instantly distinguish real from fake. This article covers the working principles, setup method, and best practices for the anti-phishing code.
What Is an Anti-Phishing Code
An anti-phishing code is a custom string of characters you set in Binance's security settings. After setup, every official email Binance sends you will prominently display this string.
The working principle is very simple:
- You set an anti-phishing code that only you know
- Binance embeds your anti-phishing code in all official emails sent to you
- When you receive an email claiming to be from Binance, check whether it contains your anti-phishing code
- If it does -- this is a genuine Binance email
- If it does not -- this is a phishing email; delete it immediately
Since scammers cannot possibly know the content of your anti-phishing code, their fake emails naturally cannot include this identifier. While the principle is simple, this feature is very effective in practice.
Detailed Steps to Set Up the Anti-Phishing Code

- Log in to your Binance account: Log in through the official website.

How to Choose a Good Anti-Phishing Code
There are some tips for choosing an effective anti-phishing code:
Recommended Practices
- Meaningful but hard to guess: Choose a phrase or combination that has special meaning to you but cannot be guessed by others.
- Appropriate length: 8-12 characters recommended; too short is easy to guess, too long is hard to remember.
- Mix of letters and numbers: Use a combination of letters and numbers for added complexity.
- Easy to recognize: Since you need to frequently check the anti-phishing code in emails, choose something you can confirm at a glance.
Not Recommended
- Do not use your name, birthday, phone number, or other personal information
- Do not use simple combinations like "123456" or "abcdef"
- Do not use strings identical or similar to your password
- Do not share your anti-phishing code with anyone

Where the Anti-Phishing Code Appears in Emails
After setup, the anti-phishing code in Binance's official emails typically appears in the following locations:
- Top of the email body: At the very top of the email content, there will be a prominent area displaying "Your Anti-Phishing Code is: [your code]."
- Visually distinct format: The anti-phishing code is usually displayed in bold or a special color for quick identification.
Every time you receive a Binance email, the first thing to check is whether the anti-phishing code is correct. If the code is absent or does not match what you set, the email is fake.
Complete Methods for Identifying Phishing Emails
The anti-phishing code is the most effective tool for identifying fake emails, but for comprehensive protection, combine it with the following methods:
Check the Sender Address
Binance's official email sender addresses typically come from these domains:
- @binance.com
- @post.binance.com
- @ses.binance.com
- @notice.binance.com
Note: Sender addresses can be spoofed (Email Spoofing), so you cannot rely solely on the sender address. It must be used in combination with the anti-phishing code.
Use Binance Verify Tool
Binance provides an official verification tool (Binance Verify). You can find this tool on the Binance website, enter email addresses, phone numbers, Telegram usernames, and other information to verify whether they belong to official Binance channels.
Check Email Content Characteristics
Phishing emails typically have these characteristics:
- Creating urgency: Claims that your account will be frozen within hours, or you have a transaction that needs immediate confirmation.
- Grammar errors: Although phishing email quality is improving, some still have grammar or formatting issues.
- Suspicious links: Links in the email with domain names inconsistent with Binance's official domain. Hover over links (without clicking) to check the actual URL.
- Requesting sensitive information: Asking you to provide passwords, private keys, seed phrases, etc. Official Binance emails will never ask for this information.

Regularly Change Your Anti-Phishing Code
For enhanced security, it is recommended to change your anti-phishing code every 3-6 months. Steps:
- Go to "Security Settings" -> "Anti-Phishing Code."
- Click "Change Anti-Phishing Code."
- Enter a new anti-phishing code.
- Complete the security verification.
After changing, the new anti-phishing code takes effect immediately. All subsequent Binance emails will use the new code.
Phishing Attack Case Studies
Case 1: Fake Account Anomaly Notification
You receive an email titled "Urgent: Abnormal Login Detected on Your Binance Account," claiming someone logged in from an unknown IP address and you need to click a link to change your password immediately. The email does not contain your anti-phishing code.
Analysis: This is a typical phishing email. The absence of the anti-phishing code is the most direct indicator. Even if you are concerned about account security, do not click the link in the email. Instead, open the Binance official website or APP directly to check your account status.
Case 2: Fake Deposit Notification
You receive an email claiming your Binance account received a large USDT deposit and you need to click a link to confirm. The email contains what appears to be a correct anti-phishing code.
Analysis: If the anti-phishing code is correct, this may be a genuine deposit notification. However, for safety, it is still recommended to open the Binance APP or official website directly to check your account balance rather than clicking the link. If you did not make any deposit, you may need to check your account security.
Case 3: Fake Event Invitation
You receive an email claiming Binance is holding a limited-time event where participants can receive BNB rewards by clicking a link and filling in information. The email does not contain your anti-phishing code.
Analysis: No anti-phishing code means it is immediately identified as a phishing email. Even if the event looks appealing, do not click. If you want to verify whether a real event exists, check directly on the Binance APP's events page.
Using the Anti-Phishing Code with Other Security Features
The anti-phishing code is the first line of defense for email security, but a comprehensive security system requires coordination of multiple features:
| Security Threat | Corresponding Protection |
|---|---|
| Phishing emails | Anti-phishing code |
| Password leak | Two-factor authentication (2FA) |
| Device theft | Device management + account lock |
| Asset transfer | Withdrawal whitelist |
| Phishing websites | Hardware security key |
It is recommended to enable the anti-phishing code together with Google Authenticator, withdrawal whitelist, and other features to form comprehensive security protection.
FAQ
Q1: Will previous emails change after setting the anti-phishing code?
A: No. The anti-phishing code only applies to emails sent after the setting is configured. Previously received Binance emails will not display the anti-phishing code.
Q2: Does the anti-phishing code appear in all Binance emails?
A: Yes. After setup, all types of official Binance emails (security alerts, transaction notifications, promotional activities, etc.) will contain your anti-phishing code.
Q3: What if I forget my anti-phishing code?
A: You can log in to the Binance security settings page to view your current anti-phishing code, or you can directly change it to a new one.
Q4: Can the anti-phishing code 100% prevent phishing attacks?
A: The anti-phishing code is very effective at identifying fake Binance emails, but it cannot prevent all types of phishing attacks. For example, phishing attacks launched through SMS or social media are not within the protection scope of the anti-phishing code. Therefore, you still need to maintain overall security awareness.
Summary
The anti-phishing code is a simple yet extremely effective security feature provided by Binance. It takes just one minute to set up but helps you easily identify all fake Binance emails. It is strongly recommended that every user set up an anti-phishing code immediately after registration and develop the habit of checking the anti-phishing code first every time they review an email. In the field of cybersecurity, the simplest protections are often the most effective.
