Quick answer: You cannot find someone’s CNIC number or name from a mobile number, because PTA, NADRA and mobile companies offer no public lookup. You can check how many SIMs are registered on your own CNIC by sending your CNIC number to 668 or using PTA’s SIM Information System, and confirm or block a SIM at your operator’s franchise with biometric verification.
“Check CNIC number with mobile number” is one of the most searched identity questions in Pakistan. Some people have forgotten their own CNIC number, some want to know which SIMs are registered in their name, and some want to find out who owns a number that keeps calling them. Each situation has a different answer. This guide explains what the Pakistan Telecommunication Authority (PTA) and NADRA really allow, and what to do in each case.
Can You Find a CNIC Number from a Mobile Number?
No. SIM ownership records are held by mobile operators and verified against NADRA’s database through biometric verification. Neither PTA, NADRA nor any mobile company offers a public service that returns a CNIC number, name or address for a mobile number.
CNIC & SIM Verification Guide
Method 1: Check SIMs on Your CNIC by SMS (668)
PTA’s 668 service is the official way to check how many SIMs are issued against a CNIC.
- Open the messaging app on any mobile phone.
- Type your 13-digit CNIC number without dashes.
- Send it to 668.
- You will receive a reply listing how many SIMs are registered on your CNIC with each mobile company, for example Jazz, Zong, Telenor or Ufone.
The reply shows counts only. It does not show phone numbers, names or activation dates. The service is free. Full details are in our guide on how many SIMs are on your CNIC.
Method 2: PTA SIM Information System (Online)
If you prefer the internet, PTA’s SIM Information System gives the same result as 668.
- Open the PTA SIM Information System portal.
- Enter your 13-digit CNIC number.
- Complete the captcha and submit.
- The page shows the number of active SIMs on your CNIC for each operator.
See the full walkthrough in our PTA SIM Information System guide.
Method 3: Confirm a SIM Is Yours at a Franchise
To confirm that a specific number is registered in your name, visit that operator’s franchise or customer service centre with your original CNIC. The staff will verify your fingerprints against NADRA records through biometric verification and confirm the numbers registered to you. This is also where you can block any SIM you do not recognise.
Forgot Your Own CNIC Number? Where to Find It
Your mobile number cannot give you your CNIC number, but these official sources can:
- Your physical CNIC: the 13-digit number is printed on the front.
- Pakistani passport: the citizenship number on your passport is your CNIC number.
- Other NADRA documents: your B-Form entry, Family Registration Certificate (FRC) or old CNIC copies.
- Bank or mobile wallet records: your bank account and wallets such as JazzCash are linked to your CNIC. See how to update your CNIC in JazzCash.
- Pak Identity app: after biometric login, your own record is shown. See how to check your NADRA CNIC details with picture.
- NADRA Registration Centre: staff can retrieve your record after fingerprint verification. Helpline: 051-111-786-100.
Found an Unknown SIM on Your CNIC? Do This
- Send your CNIC to 668 and note which operator shows an extra SIM.
- Visit that operator’s franchise with your original CNIC and ask them to block every SIM you did not buy.
- Keep the complaint or reference number they give you.
- If the operator does not act, file a complaint with PTA through its online complaint system.
- If your CNIC card itself is missing, report the lost CNIC and apply for a reprint.
A SIM registered on your CNIC can be used for fraud in your name, so check 668 every few months.
Getting Calls from an Unknown Number?
You cannot legally look up the owner of a number. Instead:
- Block the number on your phone.
- Report spam or harassment calls to your mobile operator.
- If you are threatened or scammed, file a complaint with PTA or the cybercrime authorities, and give them the number. They can trace the owner through official channels.
Warning: “SIM Owner Details” and “CNIC by Number” Websites
Many websites and apps claim to show the owner’s name, CNIC and address for any mobile number. They are not connected to PTA, NADRA or any mobile operator. They show fake or leaked data, collect the numbers you enter, and often lead to scams.
- Never enter your CNIC or OTP on a site that is not an official .gov.pk or operator website.
- PTA, NADRA and mobile companies never ask for your OTP over a phone call or WhatsApp.
- Using someone’s identity information without permission is an offence under Section 16 of the Prevention of Electronic Crimes Act (PECA) 2016.

How Banks and Companies Verify a CNIC and Mobile Number
Banks, telecom companies and other registered organisations verify a customer’s CNIC through NADRA’s paid Verisys service and biometric checks, usually with the customer present. This is why a bank can match your number to your CNIC but a website cannot. See NADRA CNIC verification for the official options.

Conclusion
A mobile number cannot be used to look up a CNIC number or owner details in Pakistan. What you can do is check how many SIMs are on your own CNIC through 668 or PTA’s SIM Information System, confirm and block numbers at your operator’s franchise, and find your own CNIC number from your documents, the Pak Identity app or a NADRA centre. Treat any site offering “SIM owner details” as unsafe.
