Code word for kids: a family password for pickup and strangers
By Trusterity · Updated 13 November 2026
A family code word lets your child check that an adult really comes from you. If someone they don't expect says “Your mum sent me”, your child asks for the word. No word, no going anywhere.
When a child uses the code word
- Someone they don't expect offers to pick them up from school, a club or a friend's house.
- An adult says there's an emergency and they must come right now.
- Older children: a call or message “from Mum” on a new number asking them to do something unusual. Voices can now be faked with AI, so the word matters on the phone too.
How to pick a good one
- Fun and easy to picture, so a young child remembers it: “purple penguin”, or a longer silly sentence for older kids.
- Not guessable: not the pet's name, the street, a favourite team or anything on a school bag or social media.
- Easy to say for every adult who might need it.

How to teach it
- Make it a game. Practise at home: you play the “stranger”, your child asks for the word.
- The child asks — the adult answers. Teach them never to say the word first, even to someone they know.
- No word, no go. If the adult doesn't know it, your child stays put, goes to a teacher or another trusted adult, and asks them to call you.
- It's a family secret. Not for best friends, not in chats, not written on anything they carry.
Who else needs it
Only adults who might really collect your child: grandparents, a regular babysitter, a trusted neighbour. Tell them in person. If you share it with someone for a one-off pickup, change it afterwards.
When to change it
After it has been used, if your child told a friend, or at the start of each school year.
Background: the FBI also recommends a secret word or phrase with your family to verify identity, as AI makes voices and images easier to fake.
Questions
At what age can a child use a code word?
Many children can remember and use a simple code word from about the age they start being collected by different adults. Keep it short for young children and practise it often.
Should the kids' code word be the same as the adults' safe word?
It can be. Some families use one simple word with young children and a longer phrase between adults for money requests.
