Introduction
In the fast-moving world of cryptocurrency, security is paramount. And for the millions of users on leading exchanges like Binance, one of the most critical components of account security is also one of the most overlooked – your phone number.
On Binance, your phone number acts as a key to your account, used for everything from logging in to authorizing withdrawals. So what happens when you get a new phone or switch numbers? How do you ensure your account stays secure?
In this comprehensive guide, we‘ll dive deep into the process of changing your phone number on Binance. We‘ll explore the risks of not keeping your number up-to-date, provide step-by-step instructions for making the switch, and highlight key considerations for Binance US users. Plus, we‘ll examine the future of identity verification in crypto and hear from experts on best practices for staying safe.
The Risks of an Outdated Phone Number
Before we get into the "how," let‘s talk about the "why." Why does it matter if the phone number attached to your Binance account is no longer in use? The simple answer is security.
In the early days of telecom, a phone number was permanently tied to a physical address. But with the advent of mobile phones, numbers became much more portable. In fact, the average American now changes their phone number once every 4 years according to data from the FCC. For ages 25-34, it‘s even more frequent at once every 2.5 years.
This modern reality of phone number turnover opens up new vulnerabilities. A hacker who gains access to your old number through a SIM swap attack or by purchasing it from a telecom employee on the black market could potentially infiltrate any accounts still tied to that number.

In the crypto world, this is especially concerning given the immutable nature of blockchain transactions. If a bad actor drains your Binance account, there‘s often no way to reverse it.
Binance has certainly not been immune to security threats. In 2019, the exchange fell victim to a large-scale hack that resulted in over 7,000 Bitcoins being stolen, worth over $40 million at the time. While Binance made all users whole through its SAFU fund, the incident highlighted the constant battle exchanges face to stay ahead of cyber criminals.
Since then, Binance has doubled down on security, implementing everything from AI-powered fraud detection to mandatory 2FA. But all of those measures can be undermined if your phone number falls into the wrong hands.
How to Change Your Phone Number on Binance
Now that we understand the stakes, let‘s walk through the actual process of updating your digits on Binance. The good news is for most users, it‘s fairly straightforward.
Step 1: Log into your Binance account and navigate to the "Security" page under your user profile.
Step 2: Next to where it shows your current phone number, click the "Change" button.
Step 3: Enter the 6-digit code sent to your current phone number to verify your identity.
Step 4: Input your new phone number and submit the 6-digit code sent to the new number.
That‘s it! Your number is now updated across your Binance account. The whole process usually takes less than 2 minutes.
However, if you no longer have access to your old phone number, you‘ll need to go through some additional verification steps. Click the "Security verification unavailable?" link and Binance will guide you through providing proof of identity like a photo ID and facial recognition check. Once the Binance team reviews and approves the information, you‘ll be able to change your number.
It‘s worth noting this process can take up to 72 hours, so it‘s best to be proactive if you know you‘ll be changing numbers soon. Don‘t wait until your old number is already deactivated.
For users of the independent Binance US exchange, the phone number change process is largely the same, with one key difference. After adding your new number, US customers need to re-complete identity verification by uploading a photo ID like a driver‘s license or passport. This extra step is to ensure Binance US remains compliant with strict KYC/AML regulations in the States.
Regional Differences
While Binance is a global exchange, it‘s important to understand that identity verification processes can vary significantly by country or region based on local laws and norms.
For example, when registering for a Chinese Binance account, users must provide their real name and national ID number in addition to a phone number. This is to comply with China‘s strict national identity system.
In the European Union, Binance must adhere to GDPR data privacy standards, which give users certain rights around accessing and deleting their personal info. This means the process for changing your phone number or other account details may involve additional acknowledgment of your GDPR rights.
As Binance expands into regions like Africa and Latin America, localization of security practices is likely to continue. The key is for users to stay informed on the specific requirements and processes for their region.
Binance Security Best Practices
Keeping your phone number up-to-date is a great first step toward securing your Binance account. But there are several other best practices you should follow to minimize your risk:
Enable 2FA with an authenticator app. While SMS 2FA is better than nothing, authenticator apps like Google Authenticator or Authy are more secure as they‘re not susceptible to SIM swapping. Binance allows you to set this up in addition to SMS 2FA.
Use a strong, unique password. Your Binance password should be long, random, and not used for any other accounts. Consider using a password manager to generate and store strong passwords.
Whitelist withdrawal addresses. By default, Binance requires you to complete 2FA for all withdrawals. But for an added layer of security, you can also enable a withdrawal address whitelist. This means you‘ll only be able to withdraw to pre-approved addresses that you‘ve added to your account.
Be wary of phishing attempts. Never click on links in unsolicited emails or messages claiming to be from Binance. Always navigate directly to the official Binance site to log in.
Monitor your account regularly. Even with robust security measures in place, it‘s smart to check your account activity frequently for any suspicious transactions or login attempts. The sooner you catch any unauthorized activity, the better chance you have of minimizing losses.
The Psychology of Security
Intellectually, most of us know how important online security is. Yet in practice, many people still take a lax approach to protecting their accounts. Why the disconnect?
Psychologists have found a few key factors that influence our cybersecurity habits:
Perceived vs actual risk. Studies show people tend to underestimate their likelihood of falling victim to a cyberattack. There‘s an "optimism bias" that it won‘t happen to us.
Friction vs convenience. Adding security measures like 2FA or complex passwords creates extra steps in our online lives. For many, the minor inconvenience outweighs the abstract security benefits.
Future discounting. This is the tendency to put more weight on short-term rewards over long-term gains. The dopamine hit of quickly logging into an account eclipses the potential future pain of being hacked.
For the most secure Binance users, recognizing these psychological pitfalls can help override our worse instincts. Regularly reminding ourselves of the very real risks, making security as frictionless as possible, and keeping the long game in mind can significantly boost our safety hygiene.
Of course, exchanges like Binance also have a responsibility to guide users toward best practices through behavioral science techniques like well-timed prompts and smart default settings. Making the secure way the easy way should be the industry standard.
The Future of Authentication
As we look to the future of identity verification in crypto, one thing is clear – our reliance on phone numbers will likely diminish. The SIM swapping epidemic has made clear that SMS is not the secure authentication channel we once thought it was.
So what will take its place? Many experts believe biometric authentication will become the norm. Think face scans, fingerprint verification, and even behavioral signals like how you type or hold your phone. Some exchanges like Bitfinex already allow biometric logins.

The benefits of biometrics are clear – they‘re unique to each user and much harder to spoof than a phone number. But there are also valid concerns around privacy and data storage that will need to be addressed as these methods become more widespread.
Decentralized identity solutions powered by blockchain could also play a role in the future of authentication. Imagine a world where your identity is anchored to a blockchain rather than a phone number – both more secure and more portable across platforms.
Binance is well-positioned to be a leader in this shift given its size and influence. The company has already shown its willingness to experiment with new authentication methods like hardware security keys. And with its expansions into adjacent industries like NFTs and blockchain-based gaming, secure cross-platform identity will only become more important.
Government regulation will also undoubtedly shape the future of identity verification in crypto. As more countries implement KYC/AML guidelines for exchanges, we could see standardization of authentication methods. But this will likely happen slowly and in a piecemeal fashion given the borderless nature of crypto.
For the foreseeable future, managing your phone number on exchanges like Binance will remain an important piece of the security puzzle – but likely not forever. As an industry, we must continue to innovate while educating users on best practices for the current paradigm. Together, we can work toward a more secure crypto ecosystem for all.
