Zong is Pakistan’s fastest-growing mobile network and the country’s leading 4G/5G provider, with over 45 million subscribers. As Zong’s network and digital services expand, so does the criminal interest in fraudulently registering Zong SIMs using stolen CNICs — particularly because Zong numbers are heavily used for internet services, data SIM fraud, and unauthorized device registrations.
This guide gives you every official, free method to check Zong SIM owner details in Pakistan — whether you want to verify your own Zong SIM’s registration, see how many Zong SIMs are on your CNIC, or confirm no Zong SIM has been registered against your identity without your consent.
Fastest Check: Send your 13-digit CNIC (no dashes) to 668 via SMS. All SIMs on your CNIC — including every Zong number — will appear in the reply within 60 seconds, completely free from any network.
Why Checking Zong SIM Owner Details Is Critical
Zong SIMs are disproportionately used for data fraud in Pakistan. Criminal use cases include:
- Registering Zong data SIMs on stolen CNICs for resale as anonymous internet connections
- Using Zong numbers for OTP interception linked to online banking and fintech apps
- Operating fraudulent e-commerce seller accounts with Zong SIMs for untraceable transactions
- Registering Zong SIMs for device verification bypasses on platforms requiring Pakistani mobile numbers
Because Zong is China Mobile’s Pakistani subsidiary and operates the widest 4G coverage network in the country, Zong SIMs are especially valuable on the fraud market — making CNIC protection for Zong registrations especially important.
Every Pakistani with a CNIC must know exactly which Zong SIMs are active under their name at all times. Regular verification takes under 60 seconds and can prevent devastating financial consequences.

Method 1: Check Zong SIM Owner Details via 668 SMS
The 668 service is PTA’s national SIM verification system that queries the live CSRS database and returns all SIMs on your CNIC across every network simultaneously — including Zong.
Step-by-Step Process:
Step 1: Open your phone’s SMS application.
Step 2: Create a new message. Address it to: 668
Step 3: Type your full 13-digit CNIC number in the message body.
- No dashes, no spaces, no dots
- Example:
3520212345671 - Double-count your digits before sending — exactly 13 required
Step 4: Send. This SMS is free on all networks including Zong.
Step 5: Receive the reply within 30–60 seconds.
Step 6: Identify Zong numbers in the reply. Zong numbers appear with the “Zong” label or carry one of these prefixes:
| Zong Prefix | Range |
|---|---|
| 0310 | All 0310-xxxxxxx numbers |
| 0311 | All 0311-xxxxxxx numbers |
| 0312 | All 0312-xxxxxxx numbers |
| 0313 | All 0313-xxxxxxx numbers |
| 0314 | All 0314-xxxxxxx numbers |
| 0315 | All 0315-xxxxxxx numbers |
| 0316 | All 0316-xxxxxxx numbers |
| 0317 | All 0317-xxxxxxx numbers |
| 0318 | All 0318-xxxxxxx numbers |
| 0319 | All 0319-xxxxxxx numbers |
Step 7: Compare every Zong number in the reply to the Zong SIMs you actually own. Any number you do not recognize is unauthorized.
Action Grid for 668 Results:
| Scenario | Action |
|---|---|
| All Zong numbers are yours | No action — check again next month |
| One unknown Zong number | Call Zong 310 + PTA 0800-55055 immediately |
| Multiple unknown Zong numbers | Emergency — call PTA first, then Zong 310 |
| 0 Zong numbers but you own a Zong SIM | Possible biometric mismatch — visit Zong franchise |
Method 2: Check Zong SIM Details via Zong Helpline (310)
Zong’s customer helpline provides agent-assisted SIM verification for your Zong account:
Steps:
Step 1: Dial 310 from your Zong SIM. This call is free from Zong numbers. (If calling from a non-Zong number, dial 021-310 with standard call rates.)
Step 2: Follow the IVR prompts — select your preferred language, then select Account or SIM Services.
Step 3: When connected to a Zong agent, request:
“I need to verify the owner registration details of my Zong SIM and confirm my CNIC-linked Zong registrations.”
Step 4: Provide identity verification when asked — typically your CNIC number and registered Zong number.
Step 5: The agent will confirm:
- Your Zong SIM’s registration status
- Whether biometric verification is complete
- Any account flags or anomalies
Step 6: To report an unauthorized Zong SIM: provide the suspected number and your CNIC. Request an urgent blocking order and get the complaint reference number.
Method 3: Check Zong SIM Details via USSD (*310#)
Zong’s USSD self-service system gives instant access to your own SIM’s account and registration information:
Steps:
Step 1: From your Zong SIM, dial *310# and press call.
Step 2: The USSD menu loads — navigate to:
- “My Account” → “Account Information” or
- “My Services” → “SIM Details”
Step 3: Select the option to view your SIM registration or account details.
Step 4: Your registered CNIC (partially masked), registration status, and account details will display.
Important Zong USSD Codes:
| Code | Function |
|---|---|
*310# | Main account menu |
*102# | Check remaining balance |
*6767# | Data balance check |
310 | Live helpline (free from Zong) |
*100# | Number enquiry (confirm your own number) |
Limitation: USSD shows your own Zong SIM only — not other Zong SIMs on your CNIC. Use 668 for the complete picture.
Method 4: Check Zong SIM Details via My Zong App
The My Zong app provides a full digital account dashboard with complete SIM registration information:
Steps:
Step 1: Download “My Zong” from Google Play Store or Apple App Store.
Step 2: Open the app and log in using your Zong number. An OTP will be sent to your Zong SIM for authentication.
Step 3: Navigate to Profile or My Account section.
Step 4: Select SIM Information or Account Details.

Zong-Specific Fraud Patterns to Watch For
Zong SIMs are targeted in specific fraud patterns that differ from other networks. Being aware of these helps you act faster:
Data SIM fraud: Criminals register Zong data SIMs (used only for internet, no calls) on stolen CNICs. These often go unnoticed for months because no calls are made — only silent data usage that consumes your CNIC slot.
Prevention: Your 668 check will catch data-only SIMs the same as regular SIMs. Check monthly.
Zong 5G device fraud: Zong’s expanding 5G network has created demand for Zong SIMs registered with CNICs to activate 5G devices illegally sold as “registered.” Your CNIC is used to provide what appears to be a legitimate registration.
Prevention: Any Zong SIM on your CNIC that you did not register yourself is unauthorized — regardless of whether it is being used for data or calls.
Roaming SIM fraud: Zong SIMs with international roaming activated have been registered fraudulently on Pakistani CNICs and sold to foreign visitors to avoid operator restrictions.
Prevention: Check 668 whenever you are traveling internationally. Your Zong SIM fraudulently used for international roaming will still appear in the 668 results.

Frequently Asked Questions — Zong SIM Owner Details Pakistan
Q: Can I check Zong SIM owner details for a number that belongs to someone else?
A: No. Pakistani law under PECA 2016 prohibits checking another person’s SIM ownership through public channels. If you have a legal reason to identify the owner of a specific Zong number (harassment, fraud), file a complaint with PTA at their official complaint portal.
Q: Does Zong charge for the 310 helpline call?
A: Calls to 310 are free from Zong numbers. If calling from a non-Zong number, standard call rates to a Zong number apply.
Q: Can I check Zong SIM details without having a Zong SIM?
A: Yes. Use the 668 service from any Pakistani SIM (Jazz, Telenor, Ufone, or SCO) to check all SIMs on your CNIC including Zong. The 668 service is not Zong-specific — it covers all networks.
Q: My Zong SIM shows BVS pending. Will it be blocked?
A: PTA periodically enforces BVS compliance and can block SIMs with unresolved pending biometric status. Visit any Zong service centre with your CNIC to complete the biometric verification before this happens.
Q: How many Zong SIMs can I have on one CNIC?
A: PTA’s limit is 5 SIMs total across all networks combined. There is no separate Jazz, Zong, or Telenor limit — but your combined total including Zong SIMs cannot exceed 5.
Q: I received an SMS from Zong saying a new SIM was activated on my account but I didn’t request it. What do I do?
A: Call Zong 310 immediately. Then call PTA 0800-55055. This is a fraud alert — act within minutes. Do not wait.
Q: How do I permanently deactivate a Zong SIM I no longer need?
A: Visit any Zong service centre with your original CNIC. Request permanent deactivation. This removes the SIM from your CNIC count in PTA’s database within 24–48 hours.
Q: Does checking Zong SIM details cost anything?
A: All official methods are free — 668, cnic.sims.pk, Zong 310 helpline (from Zong), Zong franchise visits, and the My Zong app.
