What is the English word for the red markers with a letter on them?
Google itself seem to use, well, marker, but I wonder if that’s too technology-related (like, say, pointer?).
I need a word that applies to red markers on the map above, but also to the real world object, like this: in other words, something with a pin that is literally placed on a map to indicate a point.
Thought about pin itself, pinpoint, but I am not sure about which is the best.

Google themselves use pin to select a location: dropped pin
The red bubbles are location indicators or location tags acting as locators to mark geographic points.
Locator is possibly the single word you're looking for to call the red bubbles.
