How to Check Zong SIM Owner Details in Pakistan

Zong is Pakistan’s second-largest mobile network with 45 million+ subscribers, operating on prefixes 0310 through 0318. If you need to verify Zong SIM ownership — whether to confirm your own registration, check for unauthorised numbers on your CNIC, or identify an unknown caller — there are four official methods available. This page covers all of them, in order of speed.

Why Checking Zong SIM Ownership Matters

Zong SIMs are frequently misused in SIM swap attacks and financial fraud because Zong numbers are linked to mobile wallets, bank OTP systems, and WhatsApp accounts. In 2025, PTA detected over 4.7 million unauthorised SIM registrations across all Pakistani networks. A SIM registered on your CNIC without your knowledge gives a criminal biometric-verified access to impersonate you.

Pakistani law places full responsibility on the CNIC holder for every SIM registered under their identity. Proving you did not activate a fraudulent SIM typically takes 2 to 4 years through courts.

PTA SMS Service (668): Fastest, No Internet Needed

This is the most reliable cross-network method. It works on any Pakistani mobile, including feature phones.

1. Open your SMS app.
2. Type your 13-digit CNIC number without dashes (e.g., 3520112345671).
3. Send to 668 from any network.
4. Receive a reply within 30 seconds listing SIM counts per operator.

A typical reply looks like: “Jazz: 2 active. Zong: 1 active. Ufone: 0. Telenor: 1. SCOM: 0.”

The 668 service shows how many Zong SIMs are registered against your CNIC — not the specific number. To retrieve the actual Zong number, visit a Zong franchise with your original CNIC and request a full SIM ownership printout.

PTA Web Portal (cnic.sims.pk)

The Pakistan Telecommunication Authority operates cnic.sims.pk — the official online portal for SIM registration lookup.

1. Visit cnic.sims.pk from any browser.
2. Enter your 13-digit CNIC number.
3. Complete the CAPTCHA.
4. View a table showing all SIMs across Jazz, Zong, Telenor, Ufone, and SCOM.

The portal is free and requires no account registration. It provides network names and SIM counts per CNIC — it does not display the actual mobile numbers for privacy reasons.

Zong USSD Code (*4004#)

For Zong-specific SIM registration:

1. Dial *4004# from your Zong SIM.
2. Follow the on-screen prompts.
3. The system shows all Zong SIMs registered under the CNIC linked to that SIM.

This method requires an active Zong SIM and works without internet.

Zong Helpline (310) and Customer Service Centres

Call 310 from any Zong number to reach Zong customer service. Request SIM ownership verification. The representative will ask for your CNIC and perform identity verification before sharing details.

For in-person verification: visit the nearest Zong Customer Service Centre (CSC) with your original CNIC. Franchises can tell you every Zong number registered against your identity and process blocking requests on the spot if unauthorised numbers are found.

Zong MyAccount App

Download the Zong MyAccount app from Google Play or the App Store. Log in with your Zong credentials. Under SIM Information, the app displays registration details for your active Zong SIM including the registered name and partial CNIC.

MNP SMS (667)

Send MNP to 667 from the specific Zong SIM in question. The response includes the registered owner’s name and partially masked CNIC. This works only from the SIM physically inserted in your device — you cannot send it from a different number to check a third party.

What to Do If You Find an Unauthorised Zong SIM on Your CNIC

• Note the Zong SIM count from your 668 reply.
• Call Zong helpline 310 to initiate a fraud report.
• Visit a Zong CSC with your original CNIC.
• Request biometric-based deactivation — the franchise scans your thumbprint, matches it against NADRA records, and blocks the number.
• Re-verify via 668 or cnic. sims.pk within 48 hours to confirm removal.
• File a complaint with the FIA Cyber Crime Wing at complaint.fia.gov.pk for cases involving financial fraud.

PTA SIM Limit Rule Zong and All Networks

Per PTA regulations, each CNIC can hold a maximum of 5 voice SIMs across all networks combined, plus 3 data SIMs. If you already have 5 active SIMs (across any mix of Jazz, Zong, Telenor, Ufone, SCOM), PTA’s DIRBS system will block any new SIM registration attempt on that CNIC automatically.

If your legitimate Zong SIM was blocked without reason, it may be because fraudsters pushed your CNIC to the 5-SIM limit using unauthorised registrations. A 668 check resolves this in under a minute.

Can You Check Who Owns a Specific Zong Number?

Privacy law under PECA 2016 and PTA regulations prohibit public access to another person’s SIM ownership details by entering their phone number. The only entity that can legally perform a reverse lookup on a Zong number is a law enforcement agency (FIA, police) with formal authority.

Any website or APK claiming to show the full name and CNIC of a Zong number you enter is operating outside the law. These tools typically use leaked breach data or fabricate results.

Zong SIM Prefixes

Zong numbers begin with: 0310, 0311, 0312, 0313, 0314, 0315, 0316, 0317, 0318.

If you receive a call from a number starting with any of these prefixes and want to verify the registration, the only legally available data is what 667 returns — the owner’s name for the SIM you personally control.
