The Advanced AVS (AAVS) feature is an offering from American Express that allows you to check several parameters not normally covered by a standard AVS check, including name, phone, and email.
To make use of the feature, merchants must first register with American Express and have the feature enabled in their Merchant Profile. The name, email, and phone data is extracted from the applicable children of the billToAdddress element in the Authorization request.
The only coding requirement is that you code to parse the advancedAVSResults element returned in the Authorization/Sale response message.
More detailed is provided the LitleXML Reference Guide.
