NENA describes several different Address Types in their documents:
Any city-style address that includes a house number and a street name is considered a Civic Address. Civic Addresses include a community name that may or may not be recognized by the USPS or be MSAG valid. Civic Addresses may be used as Postal address if recognized by the USPS. Civic Addresses may be used as MSAG addresses if they are an exact match to the MSAG address. A rural route delivery address or FPO or APO address is not considered a Civic Address.
Address recognized and used by the USPS (United States Postal Service) for delivery of mail. A postal address is frequently not a valid address for 9‑1‑1 purposes.
The physical location of a (static) subscriber access line. If available, a Service Address is the recommended address for 9‑1‑1 use. (May be different from the listed address or billing address.)
A component of a Civic Address that provides differentiation between features having a common street name and address number. For example: apartment, suite or lot number.
