What is an AVS (Address Verification System)?

Understanding AVS (Address Verification System) in E-commerce

Quick Definition

Address Verification System (AVS) is a security measure used in credit card transactions to reduce fraud by comparing the billing address provided by the customer with the address on file at the card-issuing bank. It helps merchants validate transaction legitimacy and minimize chargeback risks during online and card-not-present payments.

Understanding Address Verification System (AVS)

How AVS Works

When a customer enters their billing address during checkout, the payment processor compares the numeric components of the address with the issuing bank's records. The system returns a code indicating the level of address match, which merchants can use to assess transaction risk.

AVS Response Codes

CodeMeaningRisk Level
YAddress and ZIP matchLow Risk
ZZIP matches, address does notMedium Risk
NNeither address nor ZIP matchHigh Risk

Benefits of AVS

  • Fraud Prevention: Reduces unauthorized transaction risks
  • Chargeback Reduction: Minimizes potential fraudulent transaction disputes
  • Transaction Screening: Provides additional layer of payment verification

AVS Limitations

  • ⚠️Not foolproof - can generate false positives or negatives
  • ⚠️International transactions may have limited AVS support
  • ⚠️Some legitimate transactions might be incorrectly flagged

E-commerce Fraud Prevention

While AVS is crucial, it's just one component of a comprehensive fraud prevention strategy. Modern e-commerce platforms like Growth Suite offer advanced fraud detection mechanisms that go beyond traditional AVS, including behavioral analysis, machine learning-powered risk scoring, and real-time transaction monitoring.
