Welcome to OpenStreetMap!  OSM is a collaborative mapping platform, that lets users like you improve the map by sharing their local knowledge.

Editing the street name is something you can do yourself. Try this simple-to-use editor with your OSM, and add the missing name yourself: https://osmapp.org/iiylttw

It's easy, and fun!

Also, you seem to be local. Would you know the specific Del Pilar the next street is named after?
