Block Code

This is the U.S. Census block code.

Location Code

This is the Geostan code detailing the known qualities of the location.  An address location code has three characters:

• The first character is always an "A" indicating an address location.
• The second character is either an "S" (indicating a location on a street range) or an "X" (indicating a location on an intersection of two streets).
• The third character is a digit indicating other qualities about the location.

Match Code

This is a 5-character alphanumeric code indicating the accuracy of the geographic location and the quality of the address match.

For example, certain codes indicate why a match could not be made, such as no matching streets being found. Other codes may provide detailed information about how the match differs from the address provided, such as when the city name changes between the input and the output addresses.

• First character (alphabetic):  describes the type of match.
• Second character (alphanumeric): describes a change in the city type.
• Third character (alphanumeric): describes a change in the street name.
• Fourth character (alphanumeric): describes a change in the cross street (for intersections) or building name.
• Fifth character (alphanumeric): describes a change in the house/unit number.

  Note: For all characters, a value of “0” indicates no changes transpired.
