Colorado County Codes
All recorded cultural resources receive a
Smithsonian number. This is a trinomial number with a state numerical
designation (Colorado is #5), a two letter designation for the county,
and a sequential number for the resource. For example, the first
recorded site in Rio Blanco county is 5RB1. Site numbers are assigned
by writing the OAHP office or calling (303) 866-5216. Do not
assign a new site number to previously recorded sites with existing
site numbers. Please contact the OAHP staff to determine the correct
site number if a structure has been moved or if new construction
connects two previously separate properties.
