AVS for debit/credit cards - what exactly does it check?

[davidsmith2202]

Hi, sorry for making two threads in just a few hours.

When I add a card to paypal, I know that there's AVS, and the 'digits' needs to match. Is it only the digits that need to match, or is it the entire street name/post code.

For example:

Address on debit card: 15 Regal Lane, CA1 7RD
Address on stealth paypal: 15 Forest Road, EH1 7BE

Would that work? All the digits match up, but not the zipcode or the street address?
