What to Do If You Selected the Wrong International Area Code on Binance?
If you selected the wrong international area code during registration,you can usually change it yourself if you notice before KYC; once KYC is submitted and approved, it cannot be changedand you will need to contact customer support to resolve the issue. The most common cases involve Chinese users accidentally selecting an area code other than +86, or adding a leading "0" when entering their phone number.

🎯 1. First, Confirm: Specific Signs of a Wrong Area Code
Selecting the wrong area code usually results in two scenarios:
You registered with a phone number but never received the verification code— This is the most common sign. The system sent the SMS using the wrong area code, so you naturally didn't receive it.
During KYC verification, the region information doesn't match your actual location— The region selected during registration doesn't match the documents submitted for KYC.
Common error examples:
Chinese users selected+852 (Hong Kong)but entered a mainland China phone number
Chinese users selected+886 (Taiwan)but entered a +86 number
Entered a phone number with a leading "0" (e.g., 086xxxx), causing the system to recognize it incorrectly
🔧 2. Handle Based on Your Account Status
Case A: KYC Not Yet Completed
This is the ideal scenario. Before submitting KYC, you can usually correct it on the registration page or in account settings:
Return to the registration page and click thecountry/region dropdownto the left of the phone number input field
Re-select the country your phone number belongs to. For example, Chinese users should selectChina, and the system will automatically match+86
Delete the original number and re-enter the pure numeric phone number without a leading "0"
Once you can receive the verification code normally, complete the registration with the correct phone number.
Case B: KYC Submitted but Not Yet Approved
In this case, you can try:
Log in to yourBinanceaccount and go to theIdentity Verificationpage to see if you can modify the information yourself
If editable, directly update the correct region information and resubmit
If not editable, contact online customer support to explain the situation and request a correction before the review is completed
Case C: KYC Already Approved
This is the most complex case. After KYC approval,the country/region of residence information is locked and cannot be modified by yourself.
The only path is to contact Binance customer support:
Log in to your account, go to [Help Center] → [Contact Customer Support]
Explain that "the international area code was selected incorrectly during registration and needs to be corrected"
Submit identity verification materials as requested by customer support (passport or ID photo, proof of phone number ownership, etc.)
After customer support reviews and approves, they will help correct your account information
Note: After changing your country of residence, the availability of certain products (such as futures trading) may change based on the regulations of the new region.

FAQ
If I selected the wrong area code during registration but haven't passed KYC yet, can I modify it directly?
Yes. Go back to the identity verification page, find the country of residence option before submitting KYC, and modify it. After confirming, check if the phone number has the correct prefix and re-request the verification code.
What are the consequences if I don't correct the wrong area code after KYC approval?
It may affect account security verification (not receiving SMS verification codes) and could also impact subsequent operations like withdrawals. It is recommended to proactively contact customer support to correct it.
How long does it typically take for customer support to resolve this?
Address proof review usually takes 1-2 business days. Customer support response time depends on the complexity of the issue and the volume of tickets. It is advisable to prepare identity verification materials in advance to improve processing efficiency.
