What Is the 668 SMS Code, Exactly?
Think of 668 as a direct line to PTA’s SIM database. Instead of calling a helpline or visiting a website, you simply send your CNIC number as a text message, and the system checks its records to tell you how many SIMs are registered against that CNIC.
It’s a small piece of infrastructure, but it plays a big role in helping people spot unauthorized SIM registrations before those numbers cause any trouble.
How to Use 668 SMS Code in Pakistan: Step-by-Step
Step 1: Pick Any Phone With an Active SIM
You don’t need a smartphone or data connection. Even an old-fashioned keypad phone will do the job, as long as it can send a standard text message.
Step 2: Format Your CNIC Correctly
This is where a lot of people get stuck. Your CNIC must be entered as 13 digits with no dashes and no spaces. So instead of writing 42101-1234567-1, you’d type 4210112345671.
Step 3: Send the Message to 668
Open your messaging app, paste or type your CNIC number, and send it to the short code 668. There’s no fee for this message.
Step 4: Read the Automated Reply
The system will text back with the total SIM count linked to your CNIC, usually broken down by network operator. Take a screenshot if you want to keep a record with the date visible.
Step 5: Troubleshoot If Needed
If you don’t get a reply within a few minutes:
- Double-check your CNIC format — even one extra space can cause an error.
- Confirm your SIM has network signal.
- Try again after a short wait, since the system can occasionally be slow during high traffic.
- Use the alternative PTA web portal if the SMS route still isn’t working.
What the Results Actually Mean
Once you get your reply, compare the numbers against what you actually use. For example:
- If PTA shows 3 Jazz numbers but you only use 1, that’s 2 unaccounted-for SIMs.
- If the total matches what you personally own, you’re all clear.
Any mismatch is worth looking into further, since those extra numbers are technically your responsibility under current regulations.
What to Do If You Spot an Unfamiliar SIM
Finding an unknown number doesn’t have to be stressful. Here’s the general path forward:
- Note down the operator showing the mismatch.
- Visit that operator’s franchise with your original CNIC.
- Ask to disown the unauthorized number.
- Complete a quick biometric verification to confirm your identity.
- Re-check via 668 a day or two later to confirm the number has been removed.
Pakistanis living abroad can use PTA’s dedicated overseas facility to handle this without needing to visit a franchise in person.
