You can check a SIM Owner’s name using social media, reverse phone lookup tools and even government databases. However, identifying unknown callers, verifying contacts or avoiding harassment from these mystery individuals isn’t always easy. That’s why many Filipinos often ask how to check a SIM owner’s name in the Philippines. Fortunately, even with the Philippines’ strict data privacy laws, there are common workarounds to get you the information you need.
How to check the SIM owner’s name by mobile number?
Once you have their phone number, several lookup services can instantly retrieve the SIM owner’s details. The results you’ll get depend on how public the individual is. That said, here are these methods and the limitations you might face.
Utiliser la recherche inversée de numéro de téléphone
Reverse phone lookup tools are a significant first step toward finding as much information as possible about the SIM owner.
Localiser le téléphone
LocatePhone is a fantastic SIM number identifier that can help you find the name, location and carrier of the phone number using public or crowdsourced information. You’ll love how, at the very least, it reveals patterns about that phone number, including mobile carrier information that would be useful for making smart decisions about that phone number. Here’s how it works:
- Go to LocatePhone.
- Type in the Philippines phone number and hit the lookup button.

- Select “Unlock All Results.”

- Enter your email address to complete your account and access the results.
Ce numéro
ThisNumber also does a decent job of deconstructing phone numbers. It’s not meant for identifying the owner’s name. However, it can help you uncover the actual area code of the landline calling you within minutes. Here’s how it works:
- Aller à Ce numéro, and enter the Philippines phone number.

- Hit the search button and access the results.
Recherche sur les réseaux sociaux
Your social media channels can also help you identify who owns that phone number. It’s fantastic for uncovering which businesses on Facebook use that phone number. You may also check whether the phone number has been published. To use this:
- Go to the Facebook search bar and enter the phone number.
- You might find the associated profile, group or business page.
- Alternatively, store the phone number and sync your Facebook app.
- Then check the “People You May Know” section for new suggested profiles based on your contact list.
Search via Messenger apps
When you add a phone number to your contact, messaging apps can display the name the user has set for themselves. However, note that there’s a good chance the display name isn’t the user’s real name. That said, it could offer some insights into their identity. To use this avenue on WhatsApp,
- Go to the chat section and tap the plus icon.

- Next, select New Contact and enter their Philippine phone number.

- Hit the save button.

- Look for the number on WhatsApp and click to view their profile.
On Viber:
- Go to the “More” tab and click the “Add contact” button.
- Enter the phone number, including the Philippines country code.
- Confirm entry, and if the contact already has a Viber account, you’ll see their profile.
Contact mobile service providers
The most logical step is to ask your mobile service provider who the phone number belongs to. However, they won’t automatically give you an answer. Usually, telcos are prohibited from directly helping you identify the SIM owner under the Philippines’ Data Privacy Act. That said, all hope isn’t lost. They can still help by blocking the phone number. You could also provide details of your interactions with that phone number, which can help them label it for the next person who comes into contact with it.
Also note that Law enforcement can get the Telcos to reveal the identity of that individual. But this often happens in criminal cases and requires a proper court order or subpoena.
Google search mobile number
A simple Recherche Google can also help identify the phone number. When you paste the phone number into the search engine, it automatically creates a list of pages where it appears. This avenue often works if the phone number is associated with a public business, posted on a public forum, or flagged by others as a scam number. For most personal mobile numbers, you won’t find useful information. Here’s how to use this:
- Go to Google search and type in the phone number (with the Philippines country code).

- Try again without the country code for the Philippines.

- You can also try to narrow your search by placing the phone number in quotes and adding key terms like “full name” or “scam”.

Report to NTC
The Philippine government also provides the NTC website for requesting information related to scams. Note that the website won’t provide details on that SIM owner. However, you can make your reports available in a public database to help others avoid being scammed. Here’s how it works:
- To make a quick report, you can dial the NTC Hotline at 1682, available 24/7.
- Alternatively, you can email consumer@ntc.gov.ph with the full details.
- You can also call the phone numbers 89204464, 89267722, and 89213251 between 8:00 am and 5:00 pm, Monday to Friday.
With payment apps
Payment Apps often display a name after you’ve attempted to send money to their phone number. It’s an ingenious method for checking the SIM owner’s name with impeccable accuracy. You can also see their full name, but it depends on how they’ve registered on the app. To use this:
- Download and set up an account on the chosen payment app. For example, you can select between GCash, Maya Bank and other Bank apps.
- You’ll need to fund the account with at least a peso to conduct transactions.
- Type in the number you were given to view the details that come up.
- Remember to avoid accidentally sending your money to them.
