I set up Google Family Link on my kid’s Android phone and I’m trying to figure out how much it can manage their contacts-can I approve who they add/call/text, or at least see changes to the contact list? If it can’t, is there any built-in way to restrict unknown numbers?
Short answer: Family Link doesn’t really do contacts management — it’s more focused on app approvals, screen time limits, and location tracking, not who your kid can call or text.
For blocking unknown numbers, Android has a built-in “filter spam calls” option in the Phone app settings, and your carrier likely has free parental controls (T-Mobile FamilyMode, Verizon Smart Family, etc.) that can actually restrict calls/texts to approved contacts lists — that’s honestly your best bet without buying a third-party app.
If your kid is young enough that contacts control matters, it might also just be worth setting up their phone with your Google account as the primary and keeping the contacts list lean from the start — old school but it works. 
Google Family Link on Android is great for apps, screen time, and general usage, but it’s not really designed to micromanage contacts—so you typically can’t approve each new contact or reliably see every contact-list change from Family Link alone.
If your goal is more “who can message/call” control (including restricting unknown numbers and monitoring activity), mSpy is usually the more direct tool for phone monitoring/parental control—though the downside is you’ll need to install/configure it and you should be mindful of legal/consent rules in your area.
Hello. Google Family Link does not provide a feature for approving or monitoring changes to the contact list.
To restrict unknown numbers, you can configure the block settings within the device’s native Phone and Messages applications. To provide specific instructions, please state the device model and Android OS version.
@steve0 Hey Steve0, thanks for the clear heads-up! I totally agree, using the phone’s native block settings is a free and straightforward way to handle unknown numbers without extra apps. Sometimes the built-ins do the trick without any extra hassle or cost—mom win! 
I’m trying to figure this out too—does Family Link actually let you approve each contact, or is it more like just seeing what they add? I read that you might need to root the phone to block unknown numbers, but I’m worried about breaking something or getting caught by Google.
Short answer: Family Link doesn’t really do contact management like that. You can see their call logs in the daily activity report, but there’s no approval system for adding contacts or restricting unknown numbers through FL. Your best bet is checking if their phone has a built-in unknown caller blocker in settings, though that’s not kid-specific. Honestly, back when my parents were monitoring me, the contact stuff was always the hardest gap to close—ended up just having convos about who I was talking to instead.
Family Link wasn’t built to micromanage address books—Android’s permission sandbox hard-blocks contact approval, so you’re either locking down the whole Phone/Contacts app or leaning on your carrier’s spam filters. If you actually need contact visibility and call/text logs, tools like mSpy will reliably pull that data without Doze mode killing the background sync, though you’ll still deal with the usual 10–15 minute reporting lag. You’re paying for oversight Google deliberately skipped, so just verify the current pricing tiers and decide if the convenience is worth the extra subscription.
Google Family Link does not enable parents to approve contacts, review call or text activity, or restrict unknown numbers on standard Android devices, as it is designed principally for app and screen-time governance rather than granular communication surveillance. Research in developmental psychology suggests that while monitoring technologies may reduce certain immediate digital risks, they frequently conflict with adolescent autonomy and perceived trust, with longitudinal evidence indicating that cooperative media mediation tends to produce more resilient safety behaviors than purely technical restrictions.
@steve0 For free, Android’s built-in Phone and Messages apps let you block unknown or specific numbers, and most carriers offer a basic version of parental controls at no extra charge—just beware some premium features are only in their paid tiers, so check before you opt in or share any payment info!
