What you can actually do with a phone number
You cannot use a phone number alone to locate someone's phone on a map. Phone carriers do not release real-time location data to the public, and most phone tracking services you see online either do not work or require the phone owner's permission to install software first.
What you can do depends on your situation. If you own the phone, you can use built-in location tools. If someone else owns it, your options are much narrower — you need either their consent, a family relationship with specific phone plan access, or law enforcement involvement. This guide covers what actually works in each scenario.
Key Takeaways
- Built-in phone tracking (Find My iPhone, Find My Mobile, Google Find My Device) works only on phones you own or have permission to track.
- Phone carriers can locate phones in emergencies but will not do so for private individuals — only law enforcement with a warrant can request this.
- Family plans on some carriers let parents track minor children's phones, but this requires setup before the phone is lost.
- Third-party tracking apps require the phone owner to install them and grant permission, so they do not work on phones you do not control.
- If someone is missing and you believe they are in danger, contact local police instead of trying to track them yourself.
Tracking a phone you own using built-in tools
If the phone is yours, use the manufacturer's built-in location service. These work without needing the phone number — they use your account login instead.
For iPhones: Go to iCloud.com on any computer or another Apple device, sign in with your Apple ID, and select Find My iPhone. Your phone will appear on a map if it is powered on and connected to the internet. You can also make it play a sound, lock it remotely, or erase it.
For Android phones: Go to google.com/android/find on any computer, sign in with your Google account, and select Find My Device. Your phone will show on a map. You can ring it, lock it, or erase it from this page.
For Samsung phones: Go to findmymobile.samsung.com, sign in with your Samsung account, and your phone will appear on a map. Samsung's tool works even if the phone is offline — it shows the last known location.
All three of these services require you to have set them up before the phone was lost. If you never turned on location services or signed into your account on the phone, these tools will not work.
Tracking a family member's phone with parental controls
If you are a parent with a minor child on your phone plan, some carriers offer family location features. These must be set up while you still have physical access to the child's phone.
Verizon: Offers Verizon Family Locator, which shows the location of phones on your account. You set this up through your Verizon account online or by calling 1-908-559-4899. There is a monthly fee.
AT&T: Offers AT&T Family Map, which works similarly. Set it up in your AT&T account online or call 611 from an AT&T phone. This also has a monthly fee.
T-Mobile: Does not offer a dedicated family locator service, but T-Mobile customers can use Google Family Link (for Android) or Apple's built-in family sharing (for iPhone) at no extra cost.
These services work only if you set them up before the phone is lost. If your child's phone is already missing and you never installed family tracking, you cannot retroactively turn it on.
What phone carriers can and cannot do
Your phone carrier (Verizon, AT&T, T-Mobile, etc.) knows your phone's location at all times — that is how they route calls and data to you. However, they will not share this information with you, even if it is your own phone number.
Carriers release location data only to law enforcement with a valid court order or warrant. If someone is missing and you believe they are in immediate danger, contact local police and provide them with the phone number. Police can request the carrier's location records through proper legal channels.
If you call your carrier and say your phone is lost, they can help you lock the account or erase the phone remotely, but they cannot tell you where it is. They will direct you to the manufacturer's tracking tools instead.
Third-party tracking apps and why they do not work for lost phones
Apps like Life360, Google Family Link, and Apple Family Sharing can track phones, but only if the phone owner installed the app and gave permission. You cannot install tracking software on someone else's phone without their knowledge, and you cannot use an app that was never set up.
If you want to use a third-party app to track someone in the future, both people must agree to it beforehand and install it while you have access to the phone. These apps are useful for families who set them up proactively, but they do not help you find a phone that is already lost.
Be cautious of websites that claim to track any phone number without permission. These are almost always scams that either steal your money or your personal information. There is no legitimate service that can locate a phone based only on the phone number without the owner's consent.
What to do if someone is missing
If you are trying to find someone because they are missing and you are worried about their safety, contact local police immediately. Provide them with the person's phone number, last known location, and any other details. Police have legal authority to request location information from carriers and can act faster than you can.
Do not waste time trying third-party apps or websites. Do not pay money to anyone claiming they can track the phone. Call 911 if you believe the person is in immediate danger, or call your local police non-emergency line if the situation is less urgent.
If the missing person is a child, provide police with a recent photo and a description of what they were wearing. If it is an adult, explain why you believe they are in danger — for example, they have a medical condition, they left without their medication, or their disappearance is out of character.
Frequently Asked Questions
Can I track someone's phone if I have their phone number?
No. A phone number alone does not let you track location. You need either the phone owner's permission, access to their account, or law enforcement involvement. If someone is missing and you are concerned for their safety, contact local police with the phone number.
What if I lost my phone and do not remember my password?
Contact your phone manufacturer's support line. For iPhone, call Apple Support. For Android, contact Google Support. For Samsung, contact Samsung Support. They can verify your identity and help you access your account to locate your phone, even if you do not remember your password.
Do I need to pay for phone tracking services?
Built-in tools from Apple, Google, and Samsung are free. Some carriers charge a monthly fee for family locator services. Third-party apps vary — some are free, some charge monthly. Never pay an upfront fee to an unknown website claiming to track any phone number.
Can police track a phone with just the phone number?
Yes, but only with a court order or warrant. Police can request location data from carriers in missing person cases or emergencies. If you believe someone is missing and in danger, call 911 or your local police non-emergency line and provide the phone number.
What happens if I try to track someone without permission?
Tracking someone's phone without their knowledge or consent is illegal in most places and can result in criminal charges. The only legal exceptions are parents tracking minor children on a family plan they pay for, or law enforcement with a warrant.
