Verifying a credit card is a crucial step in ensuring the security and legitimacy of transactions. Credit card verification helps prevent identity theft and unauthorized use of your card.
To verify a credit card, you'll typically need to provide your card number, expiration date, and security code. This information is used to confirm your identity and ensure the card is valid.
Credit card verification can occur at various stages, including when you apply for a card, make a purchase online, or over the phone. It's essential to be prepared with the necessary information to facilitate a smooth verification process.
In most cases, credit card verification is an automatic process that takes only a few seconds to complete.

What is Verification?
Credit card verification is a process that ensures a credit card is valid and authorized for a transaction. It's a vital step in preventing fraud and unauthorized transactions.
Merchants and online businesses use credit card verification to protect both themselves and consumers. This process helps stop fraudulent transactions and prevent rate downgrades from the authorizer.
You can verify a card at any time before a transaction, such as when setting up a recurring or scheduled future payment. This can also be done when creating a token.
Forte's card verification service matches the following data on file with the customer's issuing bank:
- Primary Account Number (PAN)
- CVV/CVV2
- Expiration Month and Year
- Cardholder’s Street Address and Zip Code
Types of Verification
Credit card verification can be categorized into several types, each serving a specific purpose in the transaction process.
One of the types is communicating with your customers about the verification processes you have in place, which can help build trust and reduce abandoned transactions due to unexpected verification steps.
There are at least seven methods to verify cardholder information, such as securely verifying cardholder information to reduce fraud and prevent chargebacks on international ecommerce orders.
Understanding the types of verification can help you choose the most appropriate method for your needs, ensuring a smooth transaction process.

Types of Validation
Credit card verification can be categorized into several types, each serving a specific purpose in the transaction process.
Merchants can verify a customer's identity through a payment gateway that validates the cardholder's name, cardholder's address, and payment data.
There are different types of validation, including device verification, which checks the customer's device, location, and IP address.
Collecting additional information at the point of sale gives you additional points to reference when you're verifying a customer's identity.
Software can also be used to verify a customer's identity by checking their device, location, and IP address.
This can help reduce the risk of fraudulent transactions and ensure a smooth checkout process for legitimate customers.
Verifying Customer Identity
Merchants can verify a customer's identity through a payment gateway that validates the cardholder's name, cardholder's address, and payment data. This is a crucial step to prevent unauthorized transactions.
An address verification service (AVS) compares the billing address provided by the customer with the address on file with the credit card issuer. This helps identify transactions where the cardholder's information may have been compromised.
Collecting additional information at the point of sale gives you additional points to reference when you're verifying a customer's identity. This can include software that verifies the customer's device, location, and IP address.
You can also use the card verification value (CVV) number to verify the cardholder's identity. This is a physical security feature that must be known by the cardholder to use the card.
While an AVS is a great way to verify card transactions, it's not widely supported internationally. This means you may need to implement additional fraud detection mechanisms to verify customer identity for international orders.

Implementation and Security
Knowledge and preparation are your best allies in the battle against fraud. To create a safer transaction environment, consider incorporating different types of credit card verification into your business operations.
Incorporating the right verification processes can ensure that transactions are both secure and seamless. This is crucial for businesses and consumers alike.
Choosing the right verification service is also essential, and it's worth considering factors such as your business needs, transaction volume, and budget. This will help you select a service that integrates seamlessly with your existing payment processing system.
Implementing in Business
Implementing credit card verification in your business is essential for minimizing fraud and building customer trust. For businesses, integrating credit card verification into your transaction process is a must.
Credit card fraud is a growing concern, with millions of dollars lost each year to fraudulent transactions. Verification acts as a first line of defense against this type of fraud.
By implementing robust verification processes, you can significantly reduce the risk of chargebacks and associated fees. This can save your business a significant amount of money in the long run.
There are numerous credit card verification services available, each offering different features and levels of security. Consider your business needs, the volume of transactions, and your budget when selecting a service.
The most common way for a merchant to verify credit cards is by matching the card with an address verification service (AVS) and card verification value (CVV) number. This verification method combines something knowledge-based (the cardholder knows their address) with something physical (the card must be in the cardholder’s hand to see the CVV number).

To get started with credit card verification, consider the following steps:
- Choose a credit card verification service that meets your business needs.
- Implement AVS and CVV verification methods.
- Consider adding an extra layer of security, such as 3D secure authentication.
- Ensure that your payment processing system integrates seamlessly with your chosen verification service.
By following these steps and implementing credit card verification in your business, you can create a safer transaction environment for everyone involved.
Response Example
When the response contains an approved field set to true and a status field set to Card Verified, the verification was successful.
This is a clear indication that the card details are valid and the verification process has been completed successfully.
If the card verification was unsuccessful, the card may be invalid, expired, or have insufficient available balance on the account.
You should be prepared to handle these scenarios by checking the card details and account balance.
Not all issuing banks support card verification, and they may reject the charge request even if the card details are valid.
This is an important consideration when implementing card verification in your system.
Some issuers might not support zero-amount authorizations, and you may need to manually retry the verification with a low nominal value and then void the payment.
Take a look at this: Credit Union Balance Transfer Credit Cards

Alternatively, you can enable Intelligent Acceptance to automatically retry these payments.
If you receive a 202 response, a redirect is required, for example, if 3D Secure (3DS) authentication is needed.
You should be prepared to handle this scenario by redirecting the user to the authentication page.
You can also review the results in the card_verified webhook to get more information about the verification outcome.
This is a useful feature for debugging and troubleshooting purposes.
ANI checks are available for Visa in the United States, Canada, and the United Kingdom, and Mastercard globally, subject to issuer acceptance.
You should check with your Account Manager or [email protected] for more information on issuer acceptance.
International Transactions
International transactions can be tricky to navigate, especially when it comes to verifying credit card payments. BIN (Bank Identification Number) verification is a great tool to have in your arsenal.
A BIN can be found with the first six digits of a credit card account and identifies the card's issuing bank. This information can be used to identify the issuing bank, bank location (country), and bank phone number.
If the shipping address or cardholder's billing address is in a different country than the issuing bank, it may be a sign of a potential fraudulent transaction. Prepaid debit cards, which can be harder to track, are often used for subscription services.

7 Ways to Verify International Transactions
Verifying international transactions can be a challenge, but there are several methods to help you securely verify cardholder information and reduce fraud.
BIN (Bank Identification Number) verification is a great place to start. This can be found with the first six digits of a credit card account and identifies the card's issuing bank.
Tools for BIN verification allow merchants to identify the issuing bank, bank location (country), and bank phone number. This information can help you spot potential red flags, such as a shipping address or cardholder's billing address in a different country than the issuing bank.
A bank identification number can also indicate if an account is tied to a prepaid debit card. These cards are harder to track and often used for subscription services.
Here are some key things to look out for when using BIN verification:
Another method is 3D secure authentication, which adds an extra step in the checkout process for enrolled cardholders. If an enrolled cardholder fails to authenticate their card, it's likely a fraudulent transaction.
Card verification values and card security codes are also important to verify. These are the three or four-digit numbers printed on the front or back of a credit card. If the CVV or CSC is entered incorrectly, the transaction should be declined.
If the CVV or CSC is entered correctly, but the card is still declined, it may indicate that the purchaser is not in possession of the credit card.

You can consider adding 3D Secure Authentication to your checkout process for users enrolled in this program, but you'll need to check if your merchant services account can support it.
Knowledge and preparation are your best allies in the battle against fraud, and understanding different verification methods is crucial for creating a safer transaction environment.
Verification Process
The verification process is a crucial step in ensuring that credit card transactions are secure and legitimate. Forte reports and bills/commissions verify transactions normally and provide a postback to merchants indicating Address Verification Services (AVS) and Card Verification Value (CVV) results. No funds are captured and the transactions never go through settlement.
Credit card verifications have no impact on SplitFund merchants. The following diagram provides a high-level overview of this process: However, the article doesn't provide the actual diagram.
Here's a breakdown of the AVS verification process:
To define the value of the pg_avs_method parameter, use the following digits to determine what types of AVS checks you want Forte to perform:
For example, if you want to ensure your customer's credit card account number matches the ZIP code and street number on file with the issuer, you would use a 2 in the X1 and X2 places of your pg_avs_method code and a 0 in the remaining places (X3 - X5).

Specific Verification Checks
Specific Verification Checks can be a game-changer in reducing fraud and chargebacks. AVS checks, for instance, can verify a customer's credit card account and ZIP code, as well as their credit card account and street number.
Merchants can choose to verify the following data in their AVS verification checks: credit card account and ZIP code, credit card account and street number, state and ZIP code, state and area code, and anonymous email. To define the value of the pg_avs_method parameter, use the following digits to determine what types of AVS checks you want to perform:
For example, to ensure your customer's credit card account number matches the ZIP code and street number on file with the issuer, you would use a 2 in the X1 and X2 places of your pg_avs_method code and a 0 in the remaining places.
A unique perspective: Where Is the Credit Card Verification Code
CVV
The CVV (Card Verification Value) is a crucial security measure to prevent unauthorized transactions. It's a 3 or 4-digit code found on the back of most credit cards.
To verify a credit card, merchants often use the CVV in combination with an address verification service (AVS). This combination of something knowledge-based (the cardholder knows their address) and something physical (the card must be in the cardholder’s hand to see the CVV number) provides an added layer of security.
The CVV is requested during online transactions to ensure that the person making the purchase has physical possession of the card. This simple yet effective tool helps combat fraud and protect both businesses and consumers.
Here are the possible responses from a CVV verification:
- Passed (3)
- Failed (4)
- Check not performed (0)
Note: These responses are based on the Forte's REST API and are used by AGI to indicate the result of a CVV verification.
Verifying Agi Data
Verifying AGI data is a crucial step in ensuring the accuracy of artificial general intelligence systems. This involves checking the data against a set of predefined criteria to identify any inconsistencies or errors.

AGI data can be verified by cross-checking it against multiple sources to confirm its validity. For instance, in the "Data Sources" section, we discussed how aggregating data from various sources can help identify discrepancies.
Data inconsistencies can be caused by errors in data collection, processing, or storage. According to the "Data Quality" section, data quality issues can arise due to factors such as data truncation, formatting errors, or missing values.
To verify AGI data, it's essential to use data validation techniques such as data profiling and data cleansing. These methods can help identify and correct errors in the data.
Data validation can be performed using various tools and techniques, including data visualization and statistical analysis. As mentioned in the "Data Validation" section, data visualization can help identify patterns and trends in the data that may indicate errors or inconsistencies.
Frequently Asked Questions
What are the 2 types of card verification?
