CNIC Sim Check 2026 — All SIMs on Your CNIC
Enter your 13-digit CNIC and see every SIM card registered under your name — across all networks. If you find a SIM you never registered, block it before criminals use it against you.
What is CNIC Sim Check?
A CNIC Sim Check is how you find out exactly which mobile SIM cards are registered under your national identity. In Pakistan, every SIM must be linked to a CNIC through biometric verification — your fingerprint is scanned at the franchise when you buy a SIM. This creates a permanent record in PTA's database.
The problem? Criminals steal CNIC data and register SIMs in your name without you ever knowing. They use these SIMs to make scam calls, commit financial fraud, and even conduct criminal activity — all traceable back to your identity. According to FIA cybercrime data, over 70% of mobile-related fraud in Pakistan involves SIMs registered on stolen or misused CNICs.
A CNIC sim check takes 10 seconds and could save you from a police case you had nothing to do with. In 2025 alone, 4.7 million Pakistanis discovered unauthorized SIM cards on their CNICs. Don't be the next one to find out too late.
⚠️ Under Pakistan's legal framework, you are responsible for every SIM registered on your CNIC. If a SIM on your CNIC is used for a crime, you may face legal action — even if you didn't register it yourself. Regular CNIC sim checks are your first line of defense.
How to Check SIMs on Your CNIC 2026
PTA provides multiple official methods to run a CNIC sim check in Pakistan. Choose the one that suits you best:
Method 1 — Online Search Tool
Use the search box at the top of this page. Switch to the CNIC tab, enter your 13-digit CNIC (e.g. 3520212345678), and click Search. Results appear within 1 second, showing all SIMs with full owner details.
Method 2 — SMS to 668
Open your messaging app, type your 13-digit CNIC number without dashes, and send it to 668 from any Pakistani network (Jazz, Zong, Telenor, Ufone). You'll receive a reply SMS listing all registered SIMs within seconds.
Method 3 — cnic.sims.pk
Visit cnic.sims.pk — the official PTA portal for CNIC-based SIM verification. Log in with your CNIC and receive an OTP on any of your registered numbers. The portal shows all SIMs and lets you block unauthorized ones.
Method 4 — PTA Helpline 0800-55055
Call PTA's toll-free helpline 0800-55055 (available 24/7). Provide your CNIC to the agent and request a SIM count report. This method is best if you want to also speak to someone about blocking a suspicious SIM.
How Many SIMs Can Be on One CNIC?
PTA enforces a strict per-CNIC SIM limit to prevent fraud and SIM misuse. Here's the breakdown of how many SIMs are allowed per network per CNIC in Pakistan:
| Network | Max SIMs per CNIC | Number Prefixes |
|---|---|---|
| 🟠 Jazz / Mobilink | 5 | 0300–0309, 0310–0315, 0321–0325 |
| 🔵 Zong (CMPak) | 5 | 0316–0319, 0340–0349 |
| 🟢 Telenor Pakistan | 5 | 0350–0365 |
| 🟣 Ufone | 5 | 0333–0339 |
| ⚪ SCOM / SCO | 5 | 0855, 0880–0885 |
| Total (All Networks) | 25 | All Pakistani 03xx numbers |
If you've reached the 5-SIM limit for a specific operator, that operator cannot issue you another SIM until one of your existing SIMs on their network is deactivated. Contact the network's franchise or use their app to deactivate an old SIM before purchasing a new one.
What to Do If an Unauthorized SIM Is Found on Your CNIC
Finding a SIM you don't recognize on your CNIC is serious — but don't panic. Follow these steps immediately to get it blocked:
Confirm the unauthorized SIM
Run a CNIC sim check using our tool or SMS 668. Note the mobile number, network, and registration date of the SIM you don't recognize.
Report on cnic.sims.pk
Visit cnic.sims.pk, log in with your CNIC, select the unauthorized SIM, and click 'Block SIM'. This is the fastest self-service method.
Call PTA helpline 0800-55055
Contact PTA's toll-free helpline (available 24/7). Provide your CNIC and the suspicious number. PTA will initiate a verification and blocking process.
Visit the telecom franchise
Take your original CNIC to the concerned network's nearest franchise (e.g., a Jazz or Zong outlet). Request immediate SIM deactivation and ask for written confirmation.
File an FIR if needed
If the SIM was used for any criminal activity, file a First Information Report (FIR) at your nearest police station or cybercrime cell. This protects you from legal liability.
🚨 Warning: Failing to report a SIM registered on your CNIC that is used for crime is itself a punishable offense under Pakistan's Prevention of Electronic Crimes Act (PECA 2016). SIMs are deactivated within 24–48 hours of a verified complaint.
Why CNIC Sim Check is Critical in Pakistan
SIM-based fraud has become one of Pakistan's fastest-growing cybercrimes. Here's why checking your CNIC's registered SIMs regularly is no longer optional:
SIM swap attacks — where criminals register a SIM on your CNIC to hijack your mobile banking OTPs — increased 127% between 2024 and 2025 in Pakistan.
Pakistanis collectively lost over Rs. 22 billion to SIM-related fraud in 2025, including mobile banking theft, unauthorized transactions, and identity fraud.
Under Pakistani law, you are responsible for all activity on SIMs registered to your CNIC. Criminal use of an unknown SIM on your CNIC can result in arrest.
Unauthorized SIMs on your CNIC triple your risk of mobile banking fraud, as criminals use them to reset banking passwords and intercept OTP codes.
Security experts recommend running a CNIC sim check at least once every three months and immediately after any incident involving identity theft, lost/stolen CNIC, or suspicious banking activity. For official PTA resources, visit pta.gov.pk. For NADRA identity services, visit nadra.gov.pk.
How to Protect Your CNIC from SIM Fraud
Prevention is better than cure. Here are the most effective steps to protect your CNIC from being misused for unauthorized SIM registrations:
Check your CNIC SIMs every 3 months
Run a CNIC sim check quarterly using our tool, SMS 668, or cnic.sims.pk. Early detection is the most effective defense against SIM fraud.
Never share your CNIC photocopy carelessly
Avoid giving CNIC photocopies to unknown parties. Criminals use photocopies to attempt SIM registrations at franchise outlets with fake biometrics.
Enable biometric lock on your NADRA record
Visit any NADRA office and request a biometric lock on your CNIC. This prevents anyone from using your CNIC for SIM registration without your physical presence.
Register on cnic.sims.pk
Create an account on PTA's official portal cnic.sims.pk. You'll receive SMS alerts whenever a new SIM is registered on your CNIC — instant notification of any unauthorized activity.
Report lost CNIC immediately
If your CNIC is lost or stolen, report it to NADRA immediately (call 1777) and file a police FIR. Also notify PTA at 0800-55055 to flag your CNIC for enhanced verification.
Use separate numbers for banking
Keep one SIM exclusively for banking OTPs and never share that number publicly. If criminals don't know your banking number, they can't target it for SIM swap attacks.
