Method 1 — Send MNP to 667 (Fastest Zong Number Check)
PTA’s official 667 verification service is the fastest method to check any Zong SIM’s registered owner details.
Exact steps:
- Insert the Zong SIM you want to verify into your phone
- Open SMS application
- Type: MNP
- Send to 667
- Receive reply within 10 seconds
Sample Zong 667 reply:
Number: 0311-XXXXXXX
Registered Owner: Muhammad [Name]
CNIC: 35201-XXXXX-1
Network: Zong (China Mobile Pakistan)
Biometric Status: Verified
Registration Date: DD/MM/YYYYThis method is essential when:
- You bought a used phone with a Zong SIM already inside
- Someone gave you a Zong SIM and you want to confirm its registration
- You want to verify your own Zong SIM is in your name after registration
Legal boundary: The 667 method requires the Zong SIM to be physically in your phone. Remotely checking another person’s Zong number is illegal under PECA 2016.
Method 2 — Send CNIC to 668 (Check All Zong SIMs on Your CNIC)
To see every Zong SIM registered against your CNIC number:
Steps:
- Open SMS app on any phone
- Type your 13-digit CNIC — no dashes, no spaces
- Send to 668
- Look for the Zong line in the reply
Sample 668 reply — Zong section:
Zong: 2 SIMs active
0311-XXXXXXX (active)
0314-XXXXXXX (active)PTA limit for Zong: Maximum 5 Zong SIMs per CNIC. If your 668 reply shows more Zong SIMs than you registered, someone has fraudulently registered Zong SIMs on your identity.
