Some areas in Puerto Rico do not have street names or repetitive house numbers. The urbanization name substitutes as the street name and becomes the primary identifier in the AMS files.
Example:
MR PEDRO RÍOS
1234 URB LOS OLMOS
PONCE PR 00731-1235
There are also public housing projects (residenciales) without street names or repetitive apartment numbers. In these cases the apartment number is the primary number and the name of the public housing project becomes the street name.
