Check the SIMs on Your Own CNIC or Number
Pick a tab and press the button to see the official PTA check for your own CNIC, or for the SIM in your phone. Nothing you type leaves this page, and this site does not look up other people's numbers.
From a Pakistani mobile number alone, you can legally find out which network it is on now, by sending “N 03XXXXXXXXX” to 76367. You can also confirm who a SIM is registered to, but only for the SIM in your own hand, by sending “MNP” to 667 from it. You cannot legally get the name, CNIC or address of someone else from their number, so if an unknown caller is the problem, the answer is reporting, not looking them up.

This guide covers exactly what a number can tell you, what it cannot, and what to do about unknown callers, scams, spam and harassment. For all the official SIM checks in one place, see our main page on SIM owner details.
What you can and cannot check by number
| Question | Can you check it? | How |
|---|---|---|
| Which network is this number on now? | Yes, any number | SMS “N 03XXXXXXXXX” to 76367 |
| Which network originally issued this number? | Roughly, from the prefix | Look at the first four digits (but see the MNP caveat below) |
| Is the SIM in my phone registered to me? | Yes, your own SIM only | Send “MNP” to 667 from that SIM |
| Who owns someone else’s number? | No | Not available to the public. Report misuse instead |
| What is their CNIC or address? | No | Not available to the public |
The table also explains why “check number details Pakistan” websites that promise names and CNICs are not real. No official channel offers that, so a site that does is using fake, outdated or stolen data. See why there is no public SIM database.
Check the current network with 76367
This is the one official check that works on any Pakistani number.
- Open your SMS app.
- Type N, a space, then the full number, for example N 03XXXXXXXXX.
- Send it to 76367.
The reply names the network the number is on now, such as Jazz, Zong, Ufone, Telenor or SCOM. PTA’s page lists the charge as Rs 2 + tax. It never shows the owner’s name.
Knowing the network is useful because it tells you which operator to report a number to, and whether a “Jazz” or “Telenor” message really came from a number on that network.
What the prefix tells you, and the MNP caveat
Each operator was given its own number series, so the first four digits (such as 0300, 0311, 0333 or 0345) show which network originally issued the number.
But Mobile Number Portability (MNP) lets people move their number to a different network and keep the same digits. That means the prefix no longer proves the current network. A number that started on one operator may now be on another. If the network matters, use 76367 instead of guessing from the prefix.
A prefix also tells you nothing about the owner or where they live.
Check the SIM in your own hand with 667
If you have a SIM and want to know whose name it is registered in, for example a SIM you bought second-hand, one your family gave you, or one used by an employee:
- Put the SIM in a phone.
- Send MNP to 667 from that SIM.
The reply shows the registered owner’s name plus related details, including a partly hidden CNIC and the activation date. A small SMS charge may apply.
This only works for the SIM sending the SMS. You cannot use 667 to check a number you do not have. Our 667 guide covers this in more detail.
Why it matters: PTA said in December 2025 that every SIM must be registered in the name of its actual user, and that the registered owner is held responsible for calls, messages and data on it. If the SIM you use is in someone else’s name, or a SIM in your name is used by someone else, get it transferred at the operator’s franchise.
To see how many SIMs are registered on your own CNIC, use cnic.sims.pk or SMS your CNIC to 668. That is a different question; 667 vs 668 explains the difference.
Who is calling me? Handling unknown callers
“Who is calling me Pakistan” is one of the most common reasons people search for number details. Since you cannot see the caller’s identity, focus on protecting yourself.
Simple steps for any unknown number
- Do not share OTPs, PINs, passwords or CNIC details over the phone. Banks, PTA and operators do not ask for OTPs on calls.
- If a caller claims to be from a bank or operator, hang up and call the official helpline yourself. From your own SIM, customer care is Jazz 111, Zong 310, Ufone 333 and Telenor 345.
- Use 76367 to check whether the number is on the network it claims.
- Block the number on your phone if calls continue.
Common scam patterns
- Prize or lottery calls asking for a “processing fee” or an OTP.
- Fake verification calls claiming your SIM will be blocked unless you share a code. PTA’s 2026 blocking drive targeted SIMs on deceased or expired CNICs and illegal SIMs. It does not phone people asking for codes.
- Relative in trouble calls asking for urgent money transfers. Call the relative directly first.
Reporting spam, fraud and harassment
| Problem | Where to report |
|---|---|
| Spam or promotional SMS | Forward it to 9000 |
| Repeated nuisance calls | Your operator. Get a complaint number |
| Fraud, threats, harassment, identity misuse | NCCIA cyber crime helpline 1799, plus your operator |
| Operator did not resolve your complaint | PTA Complaint Management System (website or app) or PTA toll-free 0800-55055 |
When you complain, keep evidence: screenshots, call logs, the number, dates and any transaction details. PTA will ask for your name, contact details, the operator’s complaint number and a short description.
The National Cyber Crime Investigation Agency (NCCIA) took over cyber crime work from the FIA cyber crime wing in 2025. Investigators can identify the person behind a number through legal process. That is the lawful way to get the answer “who is this?”
Why not use a number lookup site?
Sites offering “SIM details by number” with names and CNICs are not connected to PTA, NADRA or operators. They may show wrong results, harvest the numbers you type, or ask for payment. Using someone else’s identity information without authorisation can also break PECA 2016 Section 16, which carries up to 3 years in prison, a fine of up to Rs 5 million, or both.

Frequently asked questions
Can I find the owner’s name from a mobile number?
Only for a SIM you have, using 667 from that SIM. For anyone else’s number, owner details are not available to the public.
Does 76367 work for numbers that switched networks?
Yes. It shows the current network, which is why it is more reliable than the prefix after MNP.
Can I find out which city a number is from?
No official check shows a city or location. Prefixes relate to the network, not to a city.
