What age can my child join TikTok, Snapchat or Instagram?

The short answer: TikTok, Snapchat, Instagram and WhatsApp all set a minimum age of 13. In Ireland there’s an extra layer, because the digital age of consent is 16, which means apps that rely on consent to use a child’s data need a parent’s permission for under-16s (Data Protection Commission). And in September the European Commission proposed new EU-wide limits that would change things again, although they aren’t law yet (Better Internet for Kids).

Irish experts are clear on one point: CyberSafeKids says children under 13 should not have their own social media accounts (CyberSafeKids). Beyond that, it’s a judgement call for your family, and this guide is here to help you make it.

The apps’ own minimum ages

These are the ages in each company’s current help pages or terms:

• TikTok: 13. Some features have higher limits, such as messaging during TikTok LIVE, which needs users to be 16 or 18 (Internet Matters).
• Snapchat: 13, and Snapchat notes that laws in some countries set a higher age for the app or certain features (Snapchat Support).
• Instagram: 13. Everyone aged 13 to 17 gets a “Teen Account” with stricter settings (more on those below) (Instagram).
• WhatsApp: 13, or older where a country requires it. WhatsApp’s European terms also mention parent-managed accounts for younger children where they’re available (WhatsApp terms, EEA).

It helps to know where 13 comes from. Internet Matters explains that most platforms chose 13 because of US privacy law, rather than because the content has been judged suitable for 13-year-olds (Internet Matters). So 13 is the youngest an app will accept, not a sign that it’s ready for your 13-year-old.

What Ireland’s “digital age of consent” means

The Data Protection Commission (Ireland’s data protection regulator) says the age of digital consent here is 16. Where an online service relies on consent to process a child’s personal data, it needs a parent or guardian’s consent for children under 16 (DPC).

There’s a catch the DPC is honest about: consent is only one of several legal bases a company can use, so your consent isn’t always needed for your child to open an account. Companies only have to make “reasonable efforts” to check that a parent agreed (DPC). In practice, then, 16 is not a ban, and many 13 to 15-year-olds sign up without a parent being asked.

What’s changing: the EU KIDS Act and Irish plans

On 17 September 2026 the European Commission proposed the EU KIDS Act. As proposed, it would (Better Internet for Kids):

• Ban social media accounts for under-13s. Children from 3 to 12 could use specially designed, child-friendly video services through accounts their parents set up and supervise.
• Give 13 and 14-year-olds “mini accounts”, set up with a parent’s consent, with limited features, parental controls, limited contacts and up to an hour a day.
• Set 15 as the EU-wide age for an independent account.
• Require proper age checks when new accounts are opened, and make app stores stop children downloading apps above their age rating.

This is a proposal. It now goes to the European Parliament and the Council (the EU’s member state governments) to be examined and agreed, and no start date has been set (Better Internet for Kids). Separately, the Tánaiste, Simon Harris, said in July that a blanket ban on social media for under-16s remains the Government’s preferred approach (The Irish Times).

Some rules already apply now. Under Coimisiún na Meán’s Online Safety Code, video-sharing platforms that allow under-16s must offer parental controls, and must use proper age checks, not just a typed-in birthday, to keep children away from adult content such as pornography and extreme violence. The regulator opened its first investigation under the Code, into X, in September (Law Society Gazette).

So what age is right for my child?

Nobody can give you one perfect birthday, and every family’s situation is different. What Irish experts suggest:

• Under 13: stick to the apps’ age limits. CyberSafeKids points out that age checks are weak, so younger children can sign up easily, which is why it’s worth talking about the rule rather than relying on the app to enforce it (CyberSafeKids). If your child mainly wants to chat with friends, Internet Matters suggests apps designed for under-13s as a safer alternative (Internet Matters).
• 13 and over: ask whether your child is emotionally ready for the social pressures that can come with it, and whether you’re ready for your part too (CyberSafeKids). Internet Matters suggests doing things online together first to see whether they have the skills and resilience to handle other people safely (Internet Matters).

If your under-13 already has an account, you’re far from alone, and it’s not a reason for panic. Internet Matters suggests talking regularly about why the age limits are there, and notes that each platform has its own route for reporting an underage account if you decide to close it (Internet Matters). Closing it together, with an explanation, usually goes better than deleting it behind their back.

If you say yes: the settings that help

Teen accounts on the big apps now come with stronger defaults:

• Instagram Teen Accounts are private by default, limit messages to people your teen follows or is connected to, nudge them to leave after 60 minutes a day, and mute notifications from 10pm to 7am. Under-16s need a parent’s permission, through Instagram’s supervision tools, to make any of these less strict (Instagram).
• TikTok teen accounts start private, have a one-hour daily screen time default, and turn notifications off overnight. Family Pairing links your account to your teen’s so you can set screen time and privacy limits, and Time Away can block the app during school hours (Internet Matters).

These features and menus change often, so check the app’s own help pages when you set them up. CyberSafeKids also suggests making sure the account is private, turning location sharing off on the phone and in the app, and reviewing their friends list together from time to time (CyberSafeKids). Our guide to what age to get a first smartphone covers the phone itself.

What to do next

1. Ask your child which apps their friends are actually using, and look at one together this week. You’ll learn more from ten minutes on the sofa than from any article.
2. Agree your family’s rule out loud. For example: “No social media accounts until 13, then one app at a time, set up together.” Writing it into a family screen time agreement helps it stick.
3. If you’re saying yes, set it up side by side: private account, location off, and Instagram supervision or TikTok Family Pairing switched on before the first post.
4. Talk to two or three other parents in the class. “Everyone else has it” is much easier to handle when a few families agree to wait together.
5. Keep an eye on the EU KIDS Act. If it’s agreed, the rules for under-16s will change, and the apps will have to bring in proper age checks.
