668 is Pakistan’s most important shortcode — and most Pakistanis don’t even know it exists. This single number gives you free, instant access to every SIM card registered under your CNIC across all networks. No internet needed. No app required. No charges. Just send one SMS and know exactly what’s registered on your identity within seconds.
SimOwnerDetailss.org.pk has helped hundreds of thousands of Pakistanis use the 668 service correctly. This complete guide covers everything — from sending your first SMS to interpreting results to taking action if something looks wrong.
What Is 668 and Why Does It Matter?
668 is PTA’s official shortcode for SIM registration verification. When you send your 13-digit CNIC number to 668, PTA’s central database instantly queries all five mobile operators and returns a complete count of every SIM registered under your identity.
This service was created because PTA detected 4.7 million unauthorized SIM registrations in 2025 alone. Criminals use stolen CNIC data — photocopies, leaked images, or compromised biometric records — to register SIMs for fraud, harassment, and criminal activities. The CNIC holder becomes legally responsible without even knowing these SIMs exist.
668 is your first line of defense. If you’ve never used it, you could have unauthorized SIMs operating under your name right now.
How to Use 668 — Step by Step
Step 1: Open Your Messages App
Use any Pakistani SIM card on any phone — smartphone or basic feature phone. Any network works — Jazz, Zong, Telenor, Ufone, or SCO. You don’t need internet or a specific app.
Step 2: Type Your CNIC Number
Enter your complete 13-digit CNIC number WITHOUT dashes and WITHOUT spaces.

Send the message to shortcode 668. Not 667 (that’s different). Not 669. Specifically 668.
Step 4: Wait for Reply
Your result arrives within 5 to 30 seconds. During peak hours, it may take up to 60 seconds. If no reply after 2 minutes, try again.
How to Read Your 668 Results
Sample Result:
Dear Customer,
SIMs registered on CNIC 3520112345671:
Total: 7
Jazz: 3
Zong: 2
Telenor: 1
Ufone: 1
SCO: 0How to Interpret:
Total Count: This is the total number of SIMs across all networks. Compare this with how many SIMs you ACTUALLY own and use.
Operator Breakdown: Shows how many SIMs are on each network. PTA allows maximum 5 per operator.
Red Flags — Take Immediate Action If:
🔴 Total is higher than expected: If you own 4 SIMs but the result shows 7, three unauthorized SIMs exist on your CNIC.
🔴 Operator count exceeds your ownership: If Jazz shows 3 but you only have 1 Jazz SIM, two unauthorized Jazz SIMs are registered on your CNIC.
🔴 Network you never used shows SIMs: If SCO shows 2 SIMs but you’ve never owned an SCO SIM, both are unauthorized.
🔴 Total approaches 25: If your total is near PTA’s maximum limit of 25, DIRBS may block your legitimate SIMs when the limit is exceeded.

668 vs 667 — Understanding the Difference
Many people confuse these two shortcodes. They serve completely different purposes:
| Feature | 668 | 667 |
|---|---|---|
| What you send | Your CNIC number | The word “MNP” |
| What you get | Count of ALL SIMs on your CNIC | Owner name of SPECIFIC SIM in your phone |
| Scope | All networks, all SIMs | Only the SIM currently inserted |
| Shows names | No — only counts | Yes — registered owner name |
| Shows CNIC | No | Yes — partially masked |
| Best for | Monthly CNIC monitoring | Verifying a specific SIM |
Use 668 to check HOW MANY SIMs are on your identity.
Use 667 to check WHO OWNS a specific SIM.
Both methods are covered in detail on our SIM owner details platform — completely free.
