The US Government has not yet adopted a standard for hydrographic codes similar to the Federal Information Processing Standards (FIPS) 10-4 country codes. The names and limits of the following oceans and seas are not always directly comparable because of differences in the customers, needs, and requirements of the individual organizations. Even the number of principal water bodies varies from organization to organization. Factbook users, for example, find the Atlantic Ocean and Pacific Ocean entries useful, but none of the following standards include those oceans in their entirety. Nor is there any provision for combining codes or overcodes to aggregate water bodies. The recently delimited Southern Ocean is not included.
