SIM Information Check by Mobile Number Pakistan 2026

Every mobile number active in Pakistan has an owner permanently registered in PTA’s national database. Whether you received a call from an unknown number, bought a used phone with a SIM inside, or simply want to verify your own registration — checking SIM information by mobile number is something every Pakistani needs to know how to do correctly in 2026.

This is Pakistan’s most complete guide to legally checking SIM information by mobile number — covering all five networks, all official PTA methods, and zero payment required.

What Does “SIM Information by Mobile Number” Actually Mean?

When you check SIM information by a mobile number, you are requesting the registration data linked to that specific number from PTA’s central subscriber database. This data includes the registered owner’s name, their CNIC number (partially masked for privacy), the network operator, biometric verification status, and current DIRBS activity status.

PTA maintains this data for every active SIM in Pakistan — all 194 million+ registered numbers across Jazz, Zong, Telenor, Ufone, and SCO.

Critical legal point: Pakistani law under PECA 2016 only permits you to check registration details of your own SIM or SIMs registered on your own CNIC. Checking another person’s complete SIM information without legal authorization is a criminal offense. The official methods described in this guide are designed specifically around this legal framework — they show you what you are legally entitled to see.

Method 1 — Send MNP to 667 (Fastest Check for Any SIM in Your Phone)

The 667 SMS method is PTA’s official service for checking the registered owner of any specific SIM number. It works by verifying the SIM physically present in your device.

Exact steps:

Insert the SIM number you want to check into your phone
Open your SMS application
Type exactly: MNP
Send to 667
Receive reply within 10 seconds showing registered owner name and masked CNIC

What the reply shows:

Your number 03XX-XXXXXXX is registered to:
Name: Muhammad [Last Name]
CNIC: 35201-XXXXX-1
Network: Jazz/Zong/Telenor/Ufone

Works for: Jazz, Zong, Telenor, Ufone numbers Cost: Small SMS charge may apply Legal: 100% PTA-approved official service

This is the most powerful method for checking SIM information by mobile number because it gives you the registered owner’s identity in seconds. It is the method PTA recommends when you want to verify ownership of a specific SIM card.

Method 2 — Send CNIC to 668 (Check All SIMs on Your Identity)

While the 667 method checks one specific number, the 668 service checks all mobile numbers registered against your CNIC simultaneously — showing you the complete picture of your telecom identity across all five networks.

Exact steps:

Open SMS application
Type your 13-digit CNIC — no dashes, no spaces
Example: 3520112345671
Send to 668
Receive complete breakdown by operator within 30 seconds

668 reply example:

CNIC: 35201-XXXXXXX-1
Total SIMs: 4
Jazz: 2 active (0300-XXXXXXX, 0321-XXXXXXX)
Zong: 1 active (0311-XXXXXXX)
Telenor: 0
Ufone: 1 active (0333-XXXXXXX)
SCO: 0

Use this method when:

You want to verify all your own numbers at once
You suspect unauthorized SIMs have been registered on your CNIC
You are buying a new SIM and need to check your current count before the 25-SIM limit

Method 3 — cnic.sims.pk Official PTA Web Portal

For users who prefer web-based verification or are currently outside Pakistan, PTA’s official portal provides the same information as 668 through any browser.

Steps:

Go to cnic.sims.pk
Enter your 13-digit CNIC
Complete the CAPTCHA
View all registered SIMs instantly

No registration, no payment, no app — just the official government portal.

What You CAN and CANNOT Check Legally

Action	Legal?	Method
Check your own SIM’s owner	✅ Yes	667 SMS
Check all SIMs on your own CNIC	✅ Yes	668 SMS or cnic.sims.pk
Verify a SIM given to you by someone else	✅ Yes	667 SMS (insert SIM first)
Check a random number you received a call from	❌ No	No legal method exists
Search a number in a third-party database	❌ No	Illegal under PECA 2016
Pay a website for “complete SIM data”	❌ No	Criminal offense

Any website or app claiming to show you complete name, address, and CNIC of any random number is either using stolen data or fabricated data. PTA has officially confirmed that no third party has legal access to its subscriber database. Using such services exposes you to PECA 2016 criminal liability.

What to Do If an Unknown Number Keeps Calling You

Many Pakistanis search “SIM information by mobile number” because they want to identify who is calling them from an unknown number. Here is what is legally available to you:

Step 1: Check the prefix to identify the network:

0300–0309, 0321–0322 = Jazz
0310–0318 = Zong
0340–0347 = Telenor
0330–0337 = Ufone
0355–0357 = SCO

Step 2: If receiving harassing or threatening calls, report directly to FIA Cybercrime Wing at www.fia.gov.pk or call 9911. FIA has legal authority to trace numbers and identify subscribers.

Step 3: Block the number using your phone’s built-in call blocking feature.

Step 4: If the calls constitute a genuine threat, file an FIR with your local police and provide the number — law enforcement can legally request subscriber information from operators through proper channels.
