Quick Answer
If a Temu coupon code is not working, the most common reason is eligibility. Welcome codes usually work for new users only, and the offer can depend on country, app version, cart value, and account history.
The currently published code on Promos.Coupons is acu370555, but Temu may still reject a code if your account or cart does not qualify.
The Most Common Reasons a Temu Code Fails
1. You are not a new user
Most welcome codes are intended for new accounts. If you already used Temu on the same phone, payment method, address, or account, the code may not apply.
2. The wrong country is selected
Temu offers vary by region. If your account, shipping address, app store country, or IP location points to a different country, the offer may not match the page you are viewing.
3. You typed the code incorrectly
Coupon codes are easy to mistype. Copy the code directly:
acu370555
Avoid extra spaces before or after the code.
4. The cart does not qualify
Some offers require a minimum cart value, eligible categories, or app-only checkout.
5. The offer changed
Temu campaigns can change without much notice. A code may still exist but show a different value, or it may be replaced by another campaign.
Country-Specific Checks
United States
Check that your shipping address and app region are both set to the United States. If a code fails, try applying it during sign-up rather than after browsing.
United Kingdom
Confirm that the checkout shows UK delivery and local taxes/fees correctly. If the final total changes after applying the code, review whether the cart still meets the offer terms.
Canada
If your province or postal code changes the available shipping method, the cart may recalculate. Apply the code after confirming address details.
European Union
VAT handling can affect final totals. If the discount appears lower than expected, compare the subtotal, tax, and shipping lines separately.
Brazil
Import handling and local payment flow can affect the checkout process. Make sure the payment method is accepted and the final order value qualifies.
Georgia
Check that the shipping country is Georgia and that the code is entered before final payment. If the app shows a different regional campaign, use the offer shown in the app.
Step-by-Step Fix
- Copy the code again: acu370555.
- Open Temu in the app, not only the browser.
- Sign out of old accounts if you are trying a new-user offer.
- Confirm your country and shipping address.
- Add qualifying items to your cart.
- Apply the code before payment.
- If it fails, screenshot the error and contact support.
Error Messages and What They Mean
“Code not valid”
The code may be mistyped, expired for your region, or not available for your account.
“Offer for new users only”
Temu has detected that your account does not qualify as new.
“Minimum order not met”
Add eligible items until the cart reaches the required threshold.
“Not available in your region”
Your account, shipping address, or app region does not match the offer.
Should You Create a New Account?
Do not create fake accounts or use misleading information to bypass eligibility. Temu can reject orders, cancel discounts, or limit accounts if it detects abuse.
If you are genuinely a new user, use accurate account and shipping details from the start.
