When I started working, I did not immediately realize the existence and principle of work. The topic is stuffy, but basic, without its understanding anywhere.
AVS - address verification service, a service provided by major credit card processors that allows merchants to verify ownership of the credit or debit card used by the buyer. The principle of operation of the technology is demonstrated in the flowchart.
Despite the age of this technology (the wiki article dates back to 2009), AVS is a significant factor in verifying transactions (later orders) in many US shops.
It is important to understand that this check affects the merchant's decision, but it does not affect approve or decline. That is, with certain merchant settings, approve is possible even if there is a "complete discrepancy".
What countries does AVS work in: United States
· Canada 
* Australia 
* New Zealand 
* United Kingdom 
AVS checks the numbers in the ZIP and Address 1 strings.
Example: 360 Park Ave, Apt A1, New York, NY 10022-1234, United States, AVS verification will only be performed using the selected digits. At the same time, if the card is Australian (included in the list of countries with AVS), and billing in the order is US, then the answer will be "international card", although at first glance it seems that the logical answer will be "complete discrepancy".
It is worth noting that despite the fact that AVS allows you to check the house number in the address bar, most merchants use verification only by ZIP line, which is a sufficient vulnerability of stores for savvy carders.
Accordingly, to "bypass" AVS, you will need to experimentally determine which check is enabled in the merchant: zip or zip + address 1. If only zip is checked , it will be enough just to find a CC with the same ZIP as the drop, and feel free to hang the order directly to the drop address, specifying its address in as a billing service. If the shop does not have any other anti-fraud technology (woocommerce is an example), or you pass the anti-fraud technology checks, then success is guaranteed.
