Introduction

WeChat is one of the most widely used messaging, social media, and payment platforms in the world, with over a billion active users. When you create a new WeChat account or re-verify an existing one after a security change, the platform requires you to complete phone verification. This step confirms that you have access to the phone number you registered, which reduces spam, prevents automated bot accounts, and helps you recover your account if you ever lose access. In this guide, we explain how WeChat phone verification works, what the verification code is, what phone number options you have, and how to troubleshoot common problems so you can complete the process successfully.

For quick one-time verifications, our WeChat SMS activation service provides instant temporary numbers. If you need ongoing SMS access for account recovery or future security checks, a WeChat rental number gives you exclusive use for days or weeks with flexible renewal options.

What Is Phone Verification?

Phone verification is the process where an online service sends a one-time code (usually an OTP) to a phone number you provide. You then enter that code back into the service to prove that you control the number. WeChat uses this method to ensure each account is linked to a real person and to prevent fraudulent registrations. You will encounter phone verification when signing up for WeChat, linking a WeChat Pay account, changing your phone number, or after a security-related event. This technique is standard across many apps and websites, including WhatsApp, Telegram, Google, and Facebook. It adds a layer of security because only someone with physical access to the SIM card or a virtual number inbox can complete the verification.

How Phone Verification Works

The process of WeChat phone verification follows a simple sequence. First, you enter your phone number in the correct international format, including the country code. WeChat then sends a request to its SMS gateway, which generates a unique verification code. This code is delivered via SMS to your phone number within a few seconds to a minute. The SMS message usually contains a numeric code of four to six digits and a brief instruction to enter it into the app. You then open the SMS message, read the code, and type it into the WeChat app exactly as shown. If the code matches, your number is verified and linked to your account. The code expires quickly, typically after 10 minutes, to prevent misuse. You can request a resend a limited number of times per day, but WeChat may throttle further attempts if you exceed the limit. The platform also restricts how many verification attempts can be made from the same device or IP address within a short period, which helps block automated attacks.

SMS Verification vs OTP

SMS verification and OTP are closely related. SMS verification is the method of sending a code via text message. OTP stands for One-Time Password, which is the code itself. In most cases, WeChat uses an SMS OTP: a numeric or alphanumeric code delivered by SMS that is valid for a single verification session. While OTPs can also be generated by authenticator apps (like Google Authenticator) or delivered via email, WeChat primarily relies on SMS as the delivery channel. The key difference is that SMS verification refers to the entire process of using text messages for authentication, while OTP is the specific temporary code used within that process. Together, they provide a secure way to confirm that you have access to the phone number you claim to own.

Feature	SMS Verification	OTP
Delivery Method	Sent via SMS to a mobile number	Can be sent via SMS, email, or authenticator app
Internet Requirement	No internet needed for delivery; device must have cellular signal	SMS OTP does not need internet; app-based OTP requires internet to generate or receive
Code Lifetime	Short, usually 5–10 minutes	Very short, often 30–60 seconds for app-based; SMS OTP may last a few minutes
Security	Depends on mobile network security; SIM swap attacks are possible	App-based OTP is more secure; SMS OTP has similar risks to SMS verification
Common Use	Account registration, password reset, 2FA	Login verification, transaction confirmation, account changes

Which Phone Number Should You Use?

Choosing a phone number for WeChat verification depends on your privacy needs, how long you plan to use the account, and whether you might need to receive future SMS for account recovery, WeChat Pay verification, or security alerts. Below is a detailed comparison of common phone number types.

Personal Number – This is the SIM card you use daily. It offers full, ongoing SMS reception, making it the most reliable option for account recovery and future verifications. The trade-off is that you link your personal identity to the WeChat account, which some users may find undesirable for privacy reasons. If you are comfortable sharing your personal number, it is the simplest choice.

SMS Activation Number – This is a temporary number provided by a service for a one-time verification. You receive the code and then the number is discarded. It offers high privacy because the number is not tied to your identity. However, you cannot use it to receive any future SMS, so if WeChat later asks for reverification or sends a security code, you will not be able to retrieve it. Ideal for quick account creation when you do not intend to use the account long-term. You can get started immediately with our WeChat SMS activation service for instant temporary numbers.

Rental Number – A rental number gives you access to a phone number for a defined period (e.g., a week, a month). You can receive SMS during that period. If your WeChat account requires reverification or you need to confirm a WeChat Pay transaction, the rental number will still work as long as the rental is active. This is a good middle ground between privacy and functionality. Our WeChat rental number service provides exclusive numbers with flexible rental periods to match your specific needs.

Dedicated Number – A dedicated number is a virtual number that you can use for a longer period, often with renewable access. It is not shared with other users, so it provides better privacy and reliability. You can keep the same number for months or years, making it ideal for important accounts where you need ongoing SMS access for recovery or two-factor authentication. CodesSender also provides dedicated numbers.

Real SIM / Non-VoIP Number – This is a carrier-issued phone number from a physical SIM card. It is the most widely accepted type because it is a genuine mobile number. WeChat almost always accepts real SIM numbers. The downsides are the cost of maintaining a SIM and the lack of privacy if you use your personal SIM. For business or high-stakes accounts, a real SIM is the safest bet.

Number Type	Future SMS	Privacy	Typical Use
Personal Number	Yes, full access	Low; your personal number is linked to the account	Everyday WeChat use, recovery, WeChat Pay
SMS Activation	No, one-time only	High; temporary number, not tied to you	Quick account creation when you do not expect future SMS
Rental Number	Yes, for rental period	Medium; number is shared but you can renew	Accounts that may need verification within a few weeks or months
Dedicated Number	Yes, long-term	High; private number, not shared	Important accounts requiring ongoing SMS access, such as business WeChat
Real SIM / Non-VoIP	Yes	Depends on carrier	Standard carrier-issued numbers accepted everywhere

If you only need to verify once and never use the account for anything sensitive, a temporary SMS activation number may suffice. If you plan to use WeChat regularly, a rental number or a dedicated number gives you ongoing SMS reception. Services like CodesSender offer both rental and dedicated numbers suitable for WeChat verification, allowing you to choose based on your expected usage duration. For the highest reliability, a real SIM number is always accepted, but it sacrifices privacy.

Common Phone Verification Problems

Even with the right number, verification can sometimes fail. The table below lists frequent issues and how to resolve them.

Problem	Cause	Solution
SMS not received	Number blocked, network issue, or wrong country code	Check number format (include + and country code). Ensure phone has signal. Wait a few minutes and try resend. Use a different number type if available.
Verification code expired	Code has a limited lifetime (usually 5–10 minutes)	Request a new code immediately and enter it promptly. Do not switch apps or leave the screen.
Incorrect number format	Missing country code or extra digits	Use international format: +[country code][number]. For example, +86 for China. Remove any leading zero.
Number rejected	WeChat does not accept VoIP numbers or some virtual numbers	Try a real SIM number or a dedicated non-VoIP number from a service that guarantees acceptance.
Too many attempts	Exceeded resend limit or verification throttle	Wait 24 hours before trying again from the same device or IP. Use a different network if possible.
Delayed SMS delivery	Carrier congestion or international routing	Wait 5–10 minutes. If still not received, try a different number from another country or use a rental number with better routing.
Account already verified with number	The phone number is already linked to another WeChat account	Each number can only be used for one account. Use a different number or contact WeChat support to unlink the previous account.

Step-by-Step: Complete Phone Verification

Follow these steps to verify your phone number on WeChat. We assume you have already downloaded the app and are at the verification screen.

Step 1: Choose the Appropriate Phone Number

Before starting, decide which phone number you will use. If you have a personal number, it is the simplest choice and offers the highest acceptance rate. If you prefer not to share your personal number, consider using a temporary SMS activation number from a service like CodesSender. For ongoing access, a rental or dedicated number is better because you can receive future verification messages. Make sure the number is from a country that WeChat supports – most countries are supported, but some may have restrictions.

Expected Result

You have a phone number ready that can receive SMS, and you understand whether it will be available for future verification needs.

Step 2: Enter the Number Correctly

Open the WeChat app and select your country from the dropdown list. The country code will auto-fill. Then type your phone number without the leading zero. Double-check that the country code matches your number. For example, if you have a US number, select United States (+1) and enter your 10-digit number. If you have a UK number, select United Kingdom (+44) and omit the leading 0. This step is critical – an incorrect format is one of the most common reasons for verification failure.

Expected Result

The number appears correctly in the input field, and the app shows the "Next" button active. You can proceed to the next screen.

Step 3: Request the Verification Code

Tap "Next" to send the verification request. WeChat will generate a code and send it via SMS. You may see a notification that a code is on its way. Do not close the app or navigate away. If you do not receive the code within 30 seconds, you can tap "Resend" but only do so once – multiple resends might trigger a temporary block.

Expected Result

Within a few seconds to a minute, an SMS with the verification code arrives on your phone or in your virtual number inbox.

Step 4: Wait for SMS Delivery

Keep your phone on and ensure it has cellular signal. If you are using a virtual number service, check the inbox on that service – some services display the SMS instantly. If the SMS does not arrive within 2 minutes, tap "Resend" or request a new code. Delays can happen due to network congestion, especially when using international numbers. Patience is key.

Expected Result

You receive a message containing a numeric code, typically 4–6 digits. The sender ID is usually "WeChat" or a short number.

Step 5: Enter the Verification Code

Read the code from the SMS and type it into the WeChat app exactly as shown. Codes are case-sensitive if they include letters. Do not add spaces or dashes. If you are using a virtual number service that provides the code in a web interface, copy and paste it carefully to avoid typos. Entering the wrong code three times may lock the verification process for 24 hours.

Expected Result

The app confirms that the code is correct and proceeds to the next step, often showing a success indicator.

Step 6: Complete Verification

WeChat will then link the phone number to your account. You may be asked to set a profile name, add a profile picture, or choose a security question. After completing these optional steps, your account is fully verified. You can now use WeChat to message friends, make calls, and access WeChat Pay if you have added a payment method.

Expected Result

You see a success message like "Phone number verified" and you are taken to the main WeChat interface.

Step 7: Troubleshoot If Verification Fails

If you encounter an error, refer to the Common Verification Problems section above. Common fixes include checking the number format, waiting before retrying, or using a different number type. For a detailed guide on specific issues like SMS not arriving or code rejection, read WeChat Verification Problems: SMS Not Received or Verification Failed. You can also try using a different device or network.

Expected Result

After applying the correct solution, you successfully verify the number and can move forward.

Step 8: Secure the Verified Account

Once verified, enable additional security settings such as login verification, a password, and WeChat Pay PIN. If you used a temporary number, consider linking a more permanent number later for account recovery – you can change your phone number in settings. For more details on the overall verification process, read How to Verify Your WeChat Account.

Expected Result

Your account is both verified and secured for long-term use, with a reliable number attached for future SMS.

FAQ

Why does WeChat ask for phone verification?

WeChat requires phone verification to confirm that each account belongs to a real person. This reduces spam, prevents bots from creating fake accounts, and helps you recover your account if you lose access. It is a standard security measure used by most online platforms.

Can I verify WeChat without my personal number?

Yes. You can use an SMS activation number, rental number, or dedicated number from a service like CodesSender. These options let you verify without exposing your personal phone number, while still providing a valid number for the verification process.

Does WeChat accept virtual numbers?

WeChat generally does not accept VoIP numbers or many free virtual numbers because they are often used for fraud. However, some paid rental and dedicated numbers from reputable providers may work if they are non-VoIP and come from a real mobile carrier. Check with the provider whether they guarantee acceptance for WeChat.

Why is my WeChat verification code not arriving?

The code may not arrive due to an incorrect number format, network issues, or WeChat's restrictions on international numbers. Verify that you have entered the country code correctly and that your phone has cellular signal. If you are using a virtual number, ensure the service has received the SMS. If the problem persists, try a different number or contact support.

Can I change the verified phone number later?

Yes, you can change your phone number in WeChat settings. To do so, you need access to your current number to confirm the change. If you no longer have access, account recovery may be required, which can be more complicated. That is why it is wise to choose a number you can keep long-term.

Can the same number verify more than one WeChat account?

No, WeChat generally allows one phone number per account. If you try to use a number that has already been verified for another account, you will receive an error. To create multiple accounts, you need different phone numbers.

What number type is best for WeChat verification?

If you want maximum success, use a real SIM number. For privacy, a dedicated number from CodesSender offers long-term SMS access and is likely to be accepted. For one-time use, an SMS activation number may work but carries higher risk of rejection. Rental numbers are a good middle ground if you need SMS access for a limited time.

Does WeChat require reverification?

WeChat may ask for reverification if you change devices, reset your password, or after a long period of inactivity. Having a phone number that still receives SMS makes reverification easy. If you used a temporary number and lose access, recovery becomes difficult.

Conclusion

WeChat phone verification is a straightforward process designed to protect your account and the platform's integrity. By understanding how the verification code works, what phone number types are available, and how to troubleshoot common problems, you can complete verification confidently. Whether you use your personal number or choose a rental or dedicated number from CodesSender, the key is to select a number that supports ongoing SMS reception if you plan to use WeChat long-term.
