My 5yo kid regularly comes home with a phone number scribbled down of their friend's parent's cell # that they got from a playmate from school. I've called and setup several play dates this way. I just drop my kid off to play at their house or have their kid come play at our place. Based on conversations with other parents in my neighborhood, this is the norm.

Sadly, kids in our direct neighborhood don't generally mingle or have unschedule play. Definitely different from the way I grew up (grew up in the 90s: little to no supervision, just wandered the neighborhood.)
