Set up a family phone locator

The reliable route is a provider-supported family group with explicit sharing, not a website that asks for a relative's phone number.

What to do

First, check

Choose the family's device ecosystems and review each member's sharing choices.

Then

Set up the appropriate Apple or Google family features and test them with every member present.

If it’s not that simple

Discuss visibility
Name the members, devices and intended recipients.
Configure authorised features
Use the ecosystem’s family/sharing controls.
Test together
Confirm what each member can actually see before anyone depends on the arrangement.

Share location with family by choice

Good to know

A family group does not automatically reveal every person's location at all times.
