A Geocode Is Not an Address

For instance, Puerto Rican addresses often use “urbanization” and “barrio” divisions to distinguish between otherwise identical street addresses, and mainland US software frequently has no input field for these. So should a place like Puerto Rico simply adopt What3Words as a fix for its broken address system? Using a geocode instead of an address is, in the case of What3Words, like swapping your first, middle, and last names for three names chosen at random—and, in fact, your name would be guaranteed to be as different as possible from the names of those closest to you, like your parents, spouse, and children.
