AVS (Address Verification Service) — Quick Explainer

Surprise: One little AVS code can stop an online order in its tracks 😲 AVS = Address Verification Service. During card-not-present payments (online, mail, phone), the merchant sends the billing street number (or part) and/or billing ZIP/postal code exactly as entered to the issuer 🏷️ The issuer compares that data to the billing address on file for the cardholder and returns an AVS response code — a risk signal 🔍 Common AVS codes: Y / M / X — Match (street and ZIP match) ✅ A — Address matches, ZIP doesn’t ⚠️ Z — ZIP matches, address doesn’t ⚠️ N — No match ❌ U — Address info unavailable / issuer doesn’t support AVS ❓ Merchants use AVS results to decide whether to approve, decline, or further review an order, support fraud screening, and help defend or challenge disputes. AVS is an additional risk indicator; it does not by itself authorize or decline a transaction 🛡️ Share this to help sellers and shoppers spot AVS signals 🔁.
