Geographic Zone List

REEF uses a hierarchical 8-digit code system for survey site locations. Each geographic area has its own set of codes. When completing a survey, you need to know the complete 8-digit code for the site you surveyed.

If the site that you surveyed is not currently on our list, then please email zonecode@REEF.org to request a new code to be assigned. Please provide the site name, general location, and ideally the latitude and longitude.
