binance.com and binance.us are not the same company and not the same product—they are two independently operated entities. For the vast majority of non-U.S. users, the one you should use is the global main site Binance Official Site, and download the Binance Official App (around 50MB). iOS users, check the iOS Install Guide. It only takes 5 minutes to understand the difference, which can help you avoid common issues like registering the wrong account or coins not being transferable.
Core Conclusion: They Are Two Companies
First the most important point:
- binance.com: Operated by Binance Holdings Ltd, serving users in over 180 countries and regions globally
- binance.us: Operated by BAM Trading Services Inc., serving only U.S. users
Although the two companies share the "Binance" brand, they are relatively independent at the legal entity, operations team, compliance license, and technical system levels. This is why the same Binance APP cannot log in to both platforms simultaneously.
Why Are There Two Sites
Before 2019, Binance was actually a unified global site. However, due to strict compliance requirements from the U.S. Securities and Exchange Commission (SEC) and the Financial Crimes Enforcement Network (FinCEN) for cryptocurrency exchanges, Binance proactively blocked U.S. IPs in September 2019 and simultaneously announced the establishment of Binance.US as the U.S. domestic compliant entity, specifically serving U.S. users.
This structure is common in the financial industry—cross-border companies establish independent subsidiaries as standard practice to meet regulations in different jurisdictions. For example:
- Alipay operates in mainland China, while Singapore's Alipay+ is a separate system
- PayPal global and PayPal China cross-border are also different products

Which One Should I Register
Criterion 1: Your Nationality and Residence
- U.S. citizens / green card holders / U.S. permanent residents: Must use binance.us
- Users from other countries/regions: Use binance.com
Criterion 2: Your KYC Documents
- Have U.S. SSN + U.S. address proof: Suitable for binance.us
- Use passport/non-U.S. ID: Can only register on binance.com
Criterion 3: Your Trading Needs
- Only do spot trading, a small number of coins: Both can meet needs
- Need futures, margin, options: Can only choose binance.com
- Need USD fiat channel: binance.us is more convenient
- Need RMB C2C: Only binance.com
What to Do If You Registered Incorrectly
Some users mistakenly think binance.us is a "more formal" entry and register an account, but they don't live in the U.S. This situation leads to two problems:
Problem 1: Assets cannot be withdrawn. binance.us requires completing KYC to withdraw, and non-U.S. users cannot pass KYC review (no SSN).
Problem 2: IP anomaly account ban. binance.us monitors login IPs, and non-U.S. IP logins trigger account freezing, requiring submission of extensive proof materials to unfreeze, and sometimes leading to permanent freezing.
Solutions:
- Stop logging in to binance.us
- If the account already has deposited assets, apply for coin refund via customer service ticket (requires proof)
- Re-register the correct account at binance.com
Technical Architecture Differences
This part is a bit deep but valuable for users who want to understand Binance:
- Matching engine: The two platforms use different server clusters, and order books are not shared. The price of the same coin on the two platforms can have a spread of 0.5%-2%.
- API keys: binance.com API keys cannot be used on binance.us. The two system interfaces are not interoperable.
- Deposit addresses: For the same coin, the deposit addresses on the two platforms are completely different, and wrong deposits cause fund loss.
- APP entry: binance.com uses the global APP (what everyone calls the Binance APP), while binance.us has a dedicated U.S. APP. The two APPs cannot log in to each other.
Some Common Misconceptions
Misconception 1: "binance.us is more official"
Wrong. Both are official, just serving different regions. The number of binance.com users is about 30 times that of binance.us. In terms of scale, the global version is the "main site".
Misconception 2: "You can use binance.us with a U.S. VPN"
Very dangerous. binance.us compliance review includes: IP tracing, KYC data verification, bank card location, and phone number location. Once inconsistencies are discovered, the account will be frozen directly, and funds require arbitration to recover.
Misconception 3: "Chinese users should use .us"
Completely wrong. Chinese users (if they insist on using Binance) should use binance.com. binance.us explicitly prohibits non-U.S. residents from registering, and using it is a violation.
Frequently Asked Questions
Q1: Are the coin prices on binance.com and binance.us the same?
Not exactly the same. The two platforms have independent order books. Most of the time the spread is within 1%, but during extreme market conditions (like a big drop), the spread can reach over 5%. Arbitrage teams smooth out most price differences, but for ordinary users, it's not worth cross-platform trading.
Q2: Can the two platforms transfer to each other?
No. There is no internal transfer channel between the two platforms. If you want to transfer assets from binance.us to binance.com, you must withdraw to an on-chain address yourself, then deposit on the other side, incurring on-chain fees and time costs.
Q3: What are the advantages of using binance.us?
For U.S. users, the advantages of binance.us are: fully compliant, can directly deposit USD, supports ACH transfers, complete tax reports. But non-U.S. users cannot enjoy these advantages at all.
Q4: Can my Binance APP log in to binance.us?
No. The Binance global APP and Binance.US APP are two independent products, requiring separate downloads. If you need to use binance.us, you need to separately download the Binance.US APP from the U.S. App Store.
Q5: What's the relationship between Binance Japan, Binance Turkey, and these?
These are all regional compliance sub-sites, with a similar architecture to binance.us—independent legal entities, independent operations, independent KYC. Japanese users use binance.co.jp, Turkish users use binance.tr. They are also not account-synced with binance.com.
Summary
Remember one sentence: binance.com is the global main site, binance.us only serves the U.S.. For Chinese users and the vast majority of overseas users, always use binance.com. Understanding this before registering saves a lot of subsequent trouble. If you already registered incorrectly, switch to the correct platform as soon as possible.
