Can an insert in a dictionary raise KeyError?

Question

Can this code generate a KeyError? I am new to python, I just want to clarify, since a verified insert cannot throw a KeyError exception.

def add(self, name, company):
    try:
        self.identity[self.id] = { 'name': name,
                                   'company': company }
        return self.identity
    except KeyError:
        raise NameNotAdded

Here, identity is a dictionary and id is an initialized int elsewhere and NameNotAdded is a custom exception.
