Steps
- Write a new SMS from any active Pakistani SIM.
- Type your 13-digit CNIC — digits only, no dashes or spaces.
- Send to
668. - Wait for PTA's reply (usually within a minute).
Reading the reply
The reply lists each operator and the number of active connections registered on your CNIC, for example "Jazz 2, Zong 1". It includes data-only SIMs and SIMs you may have forgotten about, such as one bought years ago for a device.
Common problems
| Problem | Fix |
|---|---|
| "Invalid CNIC" reply | Check you sent exactly 13 digits without dashes. Our CNIC Format Checker gives you a clean version. |
| No reply | Check you have SMS service and try again later, or use cnic.sims.pk. |
| Count higher than expected | Follow our unknown SIM guide. |
Using the website instead
PTA's SIM Information System at cnic.sims.pk gives the same count in a browser. It is useful if you are abroad or don't have a Pakistani SIM handy.
You can send the SMS from any SIM — it doesn't have to be registered on the CNIC you are checking. Only check your own CNIC.
Frequently asked questions
Do I include dashes when sending CNIC to 668?
No. Send 13 digits only.
Does 668 show my SIM numbers?
No. It shows the count per operator. Operators can tell you the numbers in person.
Can I use 668 from abroad?
Use cnic.sims.pk instead if you do not have an active Pakistani SIM.
