Use accurate payment and account details, complete any bank verification request, and avoid rapid repeat attempts. These steps can prevent some avoidable declines or checkout blocks, but no shopper action can guarantee that a retailer or payment provider will not review an order. If a payment is held or declined, check the order status and contact the bank or retailer through an official channel.

First, identify what “under review” means

A declined payment, a pending bank authentication, a retailer’s fraud review, and a checkout blocked before an order is created are different situations. The responsible party and the next step depend on which one occurred.

Status What it usually means What to do
Payment declined The card issuer or payment process did not approve the charge. Amazon’s US guidance recommends checking payment details and bank records; only the bank can explain why it declined a payment. Amazon: Resolve a Declined Payment Check the entered details and contact the bank if they appear correct.
Authentication pending The issuer is asking for an additional verification step before the transaction can proceed. Some Amazon UK digital orders can remain on hold while verification is pending. Amazon UK: Payment Verification for Digital Orders Complete the genuine verification prompt or ask the issuer for assistance.
Retailer fraud review The merchant is assessing order risk. Shopify says its fraud analysis can consider signals such as address verification, CVV, location, device or network activity, and use of multiple cards. These are indicators, not proof of wrongdoing. Shopify: Reviewing orders with fraud analysis Check the retailer’s account or order page and contact customer service through its official channel.
Checkout blocked The platform may temporarily prevent more attempts. Shopify notes that many orders or failed attempts from one IP address in a short period can trigger a temporary block. Shopify: Preventing fraud Stop retrying and ask the retailer or payment provider when and how to proceed.

How to reduce avoidable payment problems

  1. Check every payment detail. Confirm the card number, expiration date, security code, billing address, and phone number. Amazon advises that the billing address and phone number should match the bank’s records. Amazon’s declined-payment guidance
  2. Confirm the bank will approve the purchase. Check that funds are available and ask the issuer whether it permits the attempted online transaction. Amazon says the bank is the party that can explain a decline.
  3. Complete authentication when prompted. Use the retailer’s genuine checkout or account flow. If the request is unclear or will not complete, contact the card issuer rather than trying to bypass it.
  4. Pause before trying again. Check whether an order exists or a pending authorization appears, then follow the retailer’s instructions. Shopify says repeated attempts within a short period can contribute to a temporary block, and trying again before it expires may reset the timer. Shopify’s fraud-prevention guidance
  5. Be truthful about delivery details. A shipping address that differs from the billing address can prompt review, but it is not by itself evidence of fraud. Gifts and purchases made for someone else are legitimate examples; explain the situation to the retailer if asked rather than changing the billing address to a false one. Shopify’s fraud-prevention guidance

What a verification request is—and is not

Payment authentication is an additional check requested by a bank or payment system. Stripe describes 3D Secure as a process that may use a one-time code or biometric confirmation. Shopify says dynamic 3DS can be used when required by the issuing bank in relevant regions. Follow the issuer’s prompt; authentication is not a shopper setting or a workaround for a merchant review. Stripe: Online Store Fraud · Shopify: Preventing fraud

Deadlines and outcomes vary by retailer and order type. For the specific Amazon UK digital-order process described on its help page, an order can be canceled if verification is not completed within seven days of the verification email. That deadline should not be assumed to apply to other Amazon orders or other retailers. Amazon UK: Payment Verification for Digital Orders

What to do if the order remains held or is declined

  • Read the exact status and instructions. Check the order page and messages in the retailer’s account. Do not assume that a bank decline and a merchant review have the same remedy.
  • For a decline, follow the retailer’s retry process. Amazon US advises retrying through the order page or updating the payment method. If the payment is declined again, the order may be canceled and a new order may be needed; retailer procedures differ. Amazon: Resolve a Declined Payment
  • For an authentication hold, finish verification or contact the issuer. If the bank prompt cannot be completed, the financial institution can help with its verification process. Amazon UK: Payment Verification for Digital Orders
  • For a merchant review, ask the retailer what it needs. Use the authenticated account or official customer-service channel. A payment gateway’s review status may not appear in the merchant’s store admin if the gateway does not send status updates back, so the retailer or gateway may need to clarify it. Shopify: Reviewing orders with fraud analysis
  • Protect your payment information. Do not send card security codes or account credentials in an unsolicited email or message. Use the retailer’s authenticated flow. If you did not place the order connected to a verification request, contact the retailer directly through its official site.

What not to do

  • Do not use a VPN or proxy as an alleged way to avoid review. Network or location signals may themselves be considered in a risk assessment. Shopify: Reviewing orders with fraud analysis
  • Do not enter a fake billing address or repeatedly substitute cards to get around a check. Accurate details and the issuer’s verification process are safer than trying to disguise the transaction.
  • Do not assume a generic security product or paid service can prevent order reviews. Retailers and payment providers apply their own controls, and no such guarantee is established by the sources cited here.
