Why Coupang Verification Codes Don’t Arrive 쿠팡 인증번호 안올때
There isn’t just one reason for this issue. In fact, several technical or account-related problems might be at play. Here are some of the most common reasons:
Network Issues: Poor mobile or internet connectivity can delay or block SMS delivery. 윤과장의 소소한 일상 이야기
Carrier Filtering: Some mobile carriers automatically block certain types of messages.
Spam Filtering: If you’re using email verification, your inbox might be filtering Coupang messages into spam.
Wrong Number or Email: A simple typo can prevent the code from being delivered to the right place.
Delay in Server Response: During high traffic periods, Coupang’s servers might delay sending verification codes.
Blocked Shortcodes: Some phones or apps automatically block short SMS codes, which are used by services like Coupang.
Understanding the root of the problem is key before trying to fix it. Let’s go through the most effective solutions step-by-step.
Method: Check Your Network Connection
Before diving into more technical fixes, make sure your mobile network is working properly.
Try these quick checks:
Turn Airplane Mode on and off.
Move to an area with stronger signal.
Restart your phone to refresh your network connection.
If you’re using Wi-Fi for email verification, check your internet connection and reload your inbox.
Method: Double-Check the Input Information
This might seem obvious, but it’s easy to make a small typo in your phone number or email address, especially when you’re in a hurry.
Ensure the correct country code is selected (for example, +82 for South Korea).
Re-enter your phone number or email carefully and try sending the code again.
Even one incorrect digit can completely block the process.
Method: Look Into Spam or Promotional Folders
If you opted for email verification, open your Spam, Junk, or Promotions folders.
Coupang’s automated emails sometimes get caught in filters and never show up in your primary inbox.
If you find it there, mark it as “Not Spam” to prevent this from happening again.
Method: Disable SMS Blockers or Filtering Apps
Some phones or third-party apps include SMS filtering features to block spam messages — but they can also block verification codes.
On Android:
Go to Messages > Settings > Spam Protection
Disable any settings that filter or block unknown numbers
On iPhone:
Go to Settings > Messages
Turn off Filter Unknown Senders if it’s enabled
Also, check any security or SMS apps you’ve installed — some of them might be blocking Coupang’s shortcode.
Method: Use a Different Verification Method
If you’re not receiving the code via SMS, try switching to email verification — or vice versa.
Coupang allows you to change the method before completing the login or registration.
Sometimes a specific route may be temporarily blocked or delayed, and switching methods solves the problem instantly.
Method: Try Another Phone or Device
If nothing has worked so far, try requesting the verification code using another device.
Install the Coupang app on a different phone or tablet, log in with the same account, and request the code.
This method can bypass device-specific issues, especially if your original phone has SMS blocking or system problems.
Method: Wait and Retry Later
Coupang may throttle repeated code requests to prevent spam or abuse. If you’ve tried several times in a short span, you might be temporarily blocked.
Wait 10 to 15 minutes, then try again.
Also, avoid requesting the code more than three times in quick succession.
Method: Clear Cache or Reinstall the Coupang App
The Coupang app itself may have a corrupted cache or outdated version causing glitches.
On Android:
Go to Settings > Apps > Coupang > Storage
Tap Clear Cache and Clear Data
On iPhone:
Delete the Coupang app and reinstall it from the App Store
This can resolve hidden software bugs and refresh your app environment.
Method: Contact Coupang Customer Support
If nothing else works, it’s time to reach out directly to Coupang.
You can contact them through:
Coupang Help Center: Accessible from the app or website
Customer Service Call (Korea): 1600-2525
