"AVS verifies the numeric portions of a cardholder's billing address. For example, if the address is 101 Main Street, Highland, CA 92346, in the United States, AVS will check 101 and 92346. Sometimes AVS checks additional digits such as an apartment number, other times it does not..."

They might call it 'full address', still it's just the numeric part.

Ah thanks. Thought it was doing more but for most cases that would be enough. Most fraud isn't very sophisticated so just the number and zip would be enough.
