AliExpress errors are annoying — especially when you’re ready to pay and the order suddenly won’t go through.
Below is a practical guide to the most common AliExpress error messages (including CSC codes): what they usually mean and what to try first. If you don’t see an exact code, focus on the situation (payment, coupon, address, account security) — the fixes are often the same.
Quick checklist (try in this order)
- Wait 10–30 minutes and try again (sales and peak hours cause glitches).
- Switch platform: app → website (or website → app).
- Try another payment method / another card.
- Clear browser cache & cookies (or use an incognito window).
- If it looks like a bank/security issue — contact your bank first.
- If nothing helps — contact AliExpress support.
Window with “Order not completed” (when trying to buy a product with a coupon or promo code)
Why it happens
Most of the time, it’s one of these:
- AliExpress is overloaded (big sales, peak hours).
- The coupon/promo code doesn’t match the order conditions (minimum spend, specific store/items).
- The system flags the order because of account rules (for example, trying to use “new user” deals in a way the platform doesn’t allow).
What to do
Try these quick fixes:
1) Remove the coupon/promo code and place the order again (just to check if the code is the trigger).
2) Wait and retry later — if it’s a platform glitch, it often resolves on its own.
3) Switch app ↔ website and try again.
4) If you have multiple accounts, avoid mixing them with the same payment method — AliExpress may treat it as suspicious activity.

Errors when paying by card
CSC_7200001, CSC_7200006, CSC_7200022, CSC_7200051
Usually means your card can’t be used for this payment on AliExpress (currency/payment network restrictions, card settings, or bank limits).
Try this:
- Use a different card (ideally from another bank).
- Try another payment method available in your region.
- If the same card always fails on AliExpress, ask your bank whether online/international payments are restricted.
Error CSC_7200009
You’ve likely hit a spending/transaction limit on the card or account.
What to do:
Or pay with another card / another payment method.
Check your bank limits and raise them if possible.
CSC_7200011
There is not enough money on your bank card or account to make a payment. You need to deposit funds to retry the payment or choose an alternative method, for example, use another card.
CSC_7200012
Card details don’t pass validation.
Check:
- Expiration date
- Card number
- Cardholder name (if required)
- CVV/CVC
Then retry the payment carefully.

Error CSC_7200015
Most often this is a bank-side issue: the payment is blocked, declined, or flagged.
Common causes
- Transaction limits (daily/monthly).
- The bank flags the payment as suspicious (especially large orders or unusual activity).
- Extra verification is required by the bank.
What to do
If AliExpress is unstable (sales/peak hours), retry later.
Contact your bank and ask if the transaction is being blocked.
Try another card or payment method.
Error CSC_7200020
The platform has detected inaccuracies in your bank card data. It is recommended to carefully double-check the information you provided when placing an order, including cardholder’s name, number, expiration date, CVV/CVC/CVP code and other data to make sure they are correct.
CSC_7200021
The CVV security code of your Visa card (the three-digit number located on the back) is incorrect. Some users have also encountered this error when they have not used for a long time.
CSC_7200026
AliExpress requires additional verification for security reasons.
What to do:
- If you believe your account/card was flagged by mistake, contact AliExpress support and your bank.
- Follow the verification steps offered by the platform (if shown).
- If verification takes time, use another payment method in the meantime.

CSC_7200040
Can be caused by your bank card restrictions, which is accompanied by an appropriate notification. It is recommended to contact the issuing bank to clarify possible problems with the card or use an alternative payment method. Some banks, for protection purposes, may temporarily block the card when a series of purchases from a single source is detected to prevent possible fraud or loss of the card.
Errors 510772327, 510772400
The payment was declined (sometimes shown as a security threat).
Try:
- Use another bank card.
- Switch device/platform: app → desktop browser (or the other way around).
- If it still declines, ask your bank whether AliExpress payments are blocked.
Errors when entering address and other data: CSC_7200030, CSC_7200034
AliExpress can’t process your order because some details are missing or formatted incorrectly — most often it’s the delivery address or phone number.
What to do:
- If it happens only in the app, try the website (or vice versa).
- Re-check your name, address, postal code, and phone number.
- Save the address again and retry checkout.
Other errors on Aliexpress
Error CSC_7200029

CSC_7200052
This is usually related to account security checks.
What to do:
- Make sure you’re using your main account consistently.
- Avoid actions that can look suspicious (multiple accounts, repeated coupon abuse, unusual payment patterns).
- If you’re sure everything is legitimate, contact AliExpress support.
CSC_7200053
Often appears when the coupon you selected can’t be applied.
Fix: remove the coupon and try again, or delete it and re-add a valid one.
CSC_7200054
AliExpress detected unusual activity (for example, login from a new device/location or an unsupported payment attempt).
Fix: log in again, confirm any security prompts, and try checkout from a trusted device/network. If it repeats — contact support.
What else you can do if AliExpress keeps showing an error
If the specific steps above didn’t help, try these universal fixes:
Check with your bank
If the error looks payment-related, the fastest path is often your bank:
- Are online/international payments enabled?
- Did the transaction get declined or flagged?
- Are there limits on your card/account?
Use another payment method
Try a different card (preferably another bank) or another available payment method.
Wait and retry
Platform glitches happen — especially during big sales. Retry later and check email/app notifications for any prompts.
Switch app ↔ website
If it fails in the app, try the desktop website. If it fails on the website, try the app.
Reinstall the app (if you use mobile)
A clean reinstall can fix broken sessions and cached errors.
Clear cache/cookies or use a different browser
Corrupted cache/cookies can break checkout. Clear them or use an incognito window and try again.
Contact AliExpress support
If the error repeats for hours (or across devices), support can confirm whether your account/payment is restricted.
New account (last resort)
Creating a new account can help in rare cases, but be careful: AliExpress may block accounts if it suspects abuse of new-user deals.
Conclusion
Most AliExpress errors are caused by one of three things: a temporary platform glitch, a bank/payment restriction, or an account security check.
Start with the quick checklist (switch platform, retry later, try another payment method). If the same error persists across devices and time, contact your bank and AliExpress support — that’s usually the shortest way to unblock checkout.
