📡Zong SIM — Quick Facts
Zong, operated by China Mobile Pakistan, is one of the country’s major cellular operators with a strong 4G footprint. To check Zong SIM owner details, text MNP to 667 from the Zong SIM (free), use Zong’s network-specific USSD options, or log into cnic.sims.pk for the full PTA record. All methods are free and PTA-compliant. This guide covers each one. For a side-by-side comparison of all four PTA-approved owner-check methods across all operators, see how to check SIM owner details.
How to check Zong SIM owner details — 4 methods
Four free methods cover every Zong SIM ownership question:
- Method 1: text MNP to 667 from the Zong SIM. The universal PTA method.
- Method 2: use Zong USSD codes from a Zong SIM (the exact code varies; check Zong’s current help pages for the latest).
- Method 3: log into cnic.sims.pk for the full PTA portal view of all your Zong SIMs.
- Method 4: the My Zong app or zong.com.pk account login.
Method 1 — MNP to 667 from Zong
Standard PTA method. From the Zong SIM in question:
- Open the SMS app.
- Type
MNP(uppercase or lowercase). - Send to 667.
- Reply arrives within 30 seconds showing registered name and masked CNIC.
Zong’s 667 reply follows the standard PTA format: registered owner’s name in English, a partial CNIC with middle digits masked, and the SIM’s verification status. The lookup is free; standard Zong SMS rates may apply at carrier level. For the full 667 walkthrough including per-network response formats, see the 667 method page.
Method 2 — Zong USSD verification
Zong provides USSD-based verification accessible from Zong SIMs. The USSD code occasionally changes with operator updates — verify with Zong customer service for the current code, or check the My Zong app for the latest in-app verification option.
Some users report success with the *6611# pattern; others find this varies by region and package. The reliable fallback is always 667 SMS, which works regardless of operator-specific code changes. For a direct comparison of what 667 and 668 each return, see 667 vs 668 Pakistan.
Method 3 — cnic.sims.pk for Zong numbers
The PTA portal shows your Zong SIMs alongside SIMs on other networks. Standard portal workflow:
- Open cnic.sims.pk in any browser.
- Enter your CNIC.
- Complete captcha + OTP to a registered number.
- View full record — Zong SIMs appear with activation dates, verification statuses, and current states.
The portal is the most detailed view of any Zong SIM you own — use it when you need activation-date documentation, suspect dealer fraud, or want to identify a specific Zong number you can’t account for. For a full breakdown of what the portal exposes across all operators, see SIM database online Pakistan.
Method 4 — My Zong app
The official Zong app provides ownership confirmation through your account profile. The Account section shows your registered name and masked CNIC after login — useful for users who prefer app access over SMS workflows.
Available on Google Play and the App Store. Authentication uses your Zong number with OTP. The app’s advantage over SMS is persistent display and integration with billing and recharge functions; the disadvantage is that it requires installation and login before use.
Zong SIM check by CNIC
To see all Zong SIMs on your CNIC across the full network picture:
-
Text your CNIC to 668.
The reply includes a
Zong: Ncount showing how many Zong SIMs are registered to you. - Log into cnic.sims.pk for the individual Zong numbers, activation dates, and verification statuses.
For the comprehensive CNIC audit workflow, see the CNIC SIM check guide. For context on how the five-SIM ceiling interacts with legacy or forgotten Zong SIMs, see PTA SIM limit per CNIC Pakistan. For a broader view of what Pakistan’s SIM information system tracks, see SIM information Pakistan.
How to deactivate an extra Zong SIM
When your audit shows a Zong SIM you don’t recognise or want to remove:
- Option 1: visit any Zong franchise with your CNIC and the specific number. Request deactivation. The block takes effect immediately.
- Option 2: call Zong customer service — 310 from a Zong SIM, 03158885555 from any other number. The agent verifies your identity (CNIC + security questions) and processes the deactivation.
- Option 3: file at complaint.pta.gov.pk if you suspect dealer fraud. PTA investigates and can order deactivation plus action against the franchise involved.
Timeline: immediate blocking, with full release from your CNIC count typically within 90 days as the operator releases the number for potential reassignment. For the network-by-network deactivation guide, see deactivate extra SIM Pakistan.
Zong biometric re-verification
Re-verification triggers and procedures at Zong follow the standard PTA pattern:
- PTA-mandated campaigns notify you via SMS with a deadline (usually 30–60 days).
- Visit any Zong franchise with your original CNIC. The biometric terminal scans your fingerprint and submits to NADRA’s MBVS for fresh verification.
- Missing the deadline blocks the SIM from outgoing service. Reactivation requires re-verification with potentially additional documentation depending on how long the block has lasted.
For a full explanation of what MBVS verification involves, what each status means, and how to handle failed verification, see PTA SIM verification.
Common Zong SIM owner details problems
- 667 reply missing or delayed: the SIM may be in a pending verification state. Check cnic.sims.pk for the status or visit a Zong franchise.
- USSD codes not responding: network or service-side issue. Use 667 SMS as the fallback — it’s operator-agnostic and more reliable.
- Zong SIM showing under a different operator after MNP: this is expected — 76367 reports the current operator after number portability. The SVMS record reflects the current network assignment. For more on how SIM details resolve after MNP, see SIM details by number.
- Zong count in 668 higher than expected: old or blocked-but-not-released SIMs inflate the count. Check cnic.sims.pk for the specific numbers. For context on data currency, see fresh SIM database Pakistan.
- “Verification pending” on an active Zong SIM: MBVS sync delay. Visit a Zong franchise for fresh biometric submission.
