Most Pakistanis searching for 667 vs 668 Pakistan already know both codes deal with SIM verification, but very few understand which code to use, when to use it, and why.
PTA-aligned answer so you never pick the wrong code again. The core difference is simple: 667 checks the SIM physically in your phone, while 668 checks all SIMs registered on your CNIC. They solve two completely different problems, and you should never substitute one for the other.
What Is the 667 Code in Pakistan?
The 667 code gives you the registration details of the SIM physically inserted in your phone. It is the most direct way to confirm who a SIM belongs to when that SIM is already in your hand.
To use it, insert the SIM you want to check into your phone, open your messaging app, type MNP, and send it to 667. Within seconds, you will receive the owner’s name, a partial CNIC number, and the activation date. This service is free on most networks, though standard SMS charges of approximately Rs. 2 may apply depending on your operator.
The critical limitation of 667 is that it works exclusively for the SIM physically in your phone at that exact moment. Pakistani telecommunications law strictly limits 667 to self-check only. You cannot use it to remotely look up another person’s number, and no official channel in Pakistan permits this.
What Is the 668 Code in Pakistan?
The 668 service is PTA’s official SIM Information System. The most important distinction in the 667 vs 668 Pakistan comparison is that 668 is about your CNIC identity, not a single SIM.
It shows all active SIMs registered to your national identity number across all operators. To use 668, open your messaging app, type your 13-digit CNIC without dashes (for example, 3520212345679), and send it to 668.
You will receive an operator-wise SIM count such as “Jazz: 1. Zong: 0. Ufone: 1. Telenor: 0.” The 668 service charges Rs. 2 plus applicable taxes per SMS.

What Is the 76367 Code?
While the 667 vs 668 Pakistan comparison covers ownership and registration, the 76367 code serves a different purpose entirely. It identifies which mobile network a number belongs to, which is useful after MNP (Mobile Number Portability) porting. Sending a mobile number to 76367 returns only the current network assignment. It does not return the owner’s name, CNIC, or any registration details.
Quick Comparison: 667 vs 668 vs 76367

When to Use 667 vs 668 — Decision Guide
Use 667 when you have a physical SIM in your hand and want to know who it is registered to. Common scenarios include buying a used phone, finding a SIM card, or wanting to confirm your own SIM’s registration before a biometric deadline.
