Validate geographic coordinates

How can I validate a geographic coordinate to see if it really corresponds to a valid location? For example, -47.888477, -100.555444; These coordinates I did not get on any map, are random numbers that came to my head now to use for example, how do I know if it is a valid coordinate?

Google uses the standard WGS84 coordinate system. To validate you can consider these approximate values:

Latitude: max / min +90 to -90

Length: max / min +180 to -180
