Geographic area codes (GAC) for geographic areas associated with the community information entity. Codes from: MARC Code List for Geographic Areas. The source of a local code in subfield $b is indicated in subfield $2. The source of codes in subfield $c is ISO 3166, Codes for the representation of names of countries and their subdivisions - Part 1: Country codes or Part 2: Country subdivision codes. Information in textual form about the geographic area served may be contained in field 522 (Geographic Area Note).
Examples of GAC use would be for the geographic area the program serves or the geographic area where an organization is located. A more precise identification of geographic areas associated with a record may be contained in field 052 (Geographic Classification Code) or in field 058 (Other Geographic Classification Code). Subfield $b may be used for a local expansion of a GAC code. GACs are recorded in field 043 in order of importance.
$a - Geographic area code
MARC code for a geographic area. Each geographic area code is seven characters in length and is contained in a separate subfield $a.

$b - Local GAC code
Local code for a geographic area. The code is formulated by attaching a local subentity code to an already established geographic area code. Each local GAC associated with an item is contained in a separate subfield $b. It is recommended that standard GACs also be included in subfield $a for international exchange and understanding.
