If you’re not receiving your Coupang verification code, you’re probably stuck in the middle of something important—signing up, logging in, or even verifying payment. It’s frustrating, especially when you’re in a hurry or making a time-sensitive purchase. But don’t worry—there are several reasons why this might be happening, and even better, there are multiple methods to fix it.
In this post, I’ll walk you through the possible causes and practical solutions, one by one. Whether it’s a phone setting, network issue, or something on Coupang’s side, we’ll cover it all.
Understanding Why the Coupang Verification Code Isn’t Arriving 쿠팡 인증번호 안올때
Coupang sends verification codes via SMS or email, depending on your settings. If that code doesn’t show up, the problem could be on your end, on Coupang’s end, or somewhere in between.
The most common reasons include: 윤과장의 소소한 일상 이야기
Network issues or poor signal
Spam filter or blocked numbers
Device settings interfering with SMS reception
Carrier delays or limitations
Incorrect phone number registered
Coupang system delays or glitches
Now let’s go over the detailed fixes depending on your situation.
Check Your Mobile Signal and Network Status
The first and most obvious step: Make sure your phone is receiving SMS messages in general.
Move to an area with better reception if you’re in a place with weak signal.
Try toggling airplane mode on and off to refresh your network connection.
If you’re using Wi-Fi calling or data-based SMS services (like RCS or iMessage), try switching to regular mobile data or disabling those temporarily.
Restart Your Phone
A simple restart often solves issues you might not even realize are affecting your phone.
By restarting, you force your messaging app and network connections to refresh.
This can clear up minor glitches that block SMS messages from coming through.
Check If Coupang Is Sending the Code to the Right Number
Sometimes the issue is as simple as a typo.
Double-check the phone number you’ve registered with Coupang.
If you’re trying to sign up, make sure you didn’t accidentally enter a wrong digit.
If you’re logging in, go into your Coupang settings (from another device or browser if needed) and confirm the registered number.
If you recently changed your number, the old one might still be listed as default.
Look in Your Spam or Blocked Messages Folder
Yes, SMS apps sometimes filter messages into hidden folders.
Go to your messaging app settings and check for any spam or blocked messages folders.
Also, check if Coupang’s number has been added to your block list.
Even accidentally blocking the sender can cause you to miss every code.
You can also try deleting and reinstalling your default messaging app if you think it’s bugging out.
Make Sure Your Carrier Isn’t Blocking Coupang Messages
Some carriers may block or delay messages from certain short codes or promotional sources.
Contact your mobile provider’s customer service and ask them to verify that Coupang’s SMS is not being filtered or blocked on your number.
Ask specifically whether international or automated text messages are allowed on your plan.
Delete Old Messages If Your Inbox Is Full
On older Android phones, a full SMS inbox can actually prevent new messages from coming in.
Go to your messaging app and delete older messages, especially if you’re getting storage full warnings.
Also, free up general device storage, since a full device can cause background apps like SMS to malfunction.
Try Using Email Instead of SMS
If SMS isn’t working at all, try selecting the email verification option during Coupang login or sign-up (if available).
Make sure the email address registered with your Coupang account is active and accessible.
Also check your email spam folder for the code.
Re-Request the Code After a Short Wait
Sometimes there’s simply a delay on Coupang’s side.
Wait 1-2 minutes before trying again.
Avoid clicking “Resend Code” repeatedly within seconds—it can actually slow down delivery or result in a temporary block.
If you’ve tried multiple times, wait 10–15 minutes before retrying.
Coupang’s servers may implement a brief timeout to prevent abuse.
Switch to a Different Device or Browser
Sometimes the device or browser you’re using may be part of the issue.
If you’re on a mobile browser, switch to the Coupang app.
If you’re on the app and not receiving codes, try logging in through the web version.
Changing platforms can help bypass app-specific glitches.
Update the Coupang App
An outdated version of the Coupang app might not sync properly with their authentication system.
Go to your app store, check for updates, and install the latest version of Coupang.
App updates often contain bug fixes, especially for login and authentication issues.
Clear Cache and Data for the Coupang App
This is especially helpful if you’re using Android.
Go to Settings > Apps > Coupang
Tap on Storage & Cache
Clear both Cache and App Data
Relaunch the app and try again
Note: You might need to log in again after clearing the data.
