All about the under 18s account

Under 18 accounts are a free account for children aged 6–17. It’s linked to your Monzo current account, so your child gets their own card and child-friendly app while you stay in control.

As the parent or guardian, you own the account and the money in it. Your child can use their card, see their balance and activity, and use the features available in their app. You can keep an eye on their spending, add money, manage limits and control how the card can be used.

With an under 18s account, your child can:

  • use their card in shops and online

  • see their balance and activity in their own app

  • use Pots, if they’re available in their app

  • freeze their card if it’s lost

  • customise parts of their app

  • use Apple Pay or Google Pay from age 14, if the option shows in their app and their device supports it

They can’t use these features yet:

  • Bizum

  • child bank transfers

  • payment requests

  • Monzo-to-Monzo payments from the child account

To open an under 18s account, you’ll need a Monzo Spain current account. During sign-up, we’ll ask for your child’s details and an ID document. Spanish citizens need a DNI (Documento Nacional de Identidad), EU/EEA or Swiss citizens need a passport or national identity card, and people who aren’t in those groups need a passport or TIE (Tarjeta de Identidad de Extranjero) the

Eligible deposits are protected up to €100,000 per person, per bank. For under 18s accounts, this limit is combined with your other eligible deposits at Monzo.
