Names of streets, plazas and other features are often unwieldy, and usually appear abbreviated on maps. So Avenida Libertador General Bernardo O'Higgins might appear on a map as Avenida B O'Higgins, just O'Higgins or even by a colloquial alternative (Alameda). The common address costanera denotes a coastal road.

Some addresses include the expression local (locale) followed by a number. Local means it's one of several offices at the same street address. Street numbers may begin with a zero, eg Bosque Norte 084. This confusing practice usually happens when an older street is extended in the opposite direction, beyond the original number 1.

The abbreviation 's/n' following a street address stands for sin número (without number) and indicates that the address has no specific street number.
