At what age do children typically know their first and last name?

Children typically begin to know their first and last name around the age of 4 years. At this stage in their development, many children are becoming more aware of their identity and the world around them. They often start to grasp the concept of names as part of their social environment and can articulate both their first and last name to others. This milestone is indicative of their growing linguistic abilities, self-awareness, and cognitive development, which is observed as they engage in conversations with adults and peers.

By this age, children have usually been introduced multiple times to their names through family interactions, social situations, and educational settings, allowing them to internalize this information. This skill is a building block for further development in social interactions and communication.
