We do not run this check. SimCheck.pk has no access to PTA or NADRA databases and never asks for your CNIC. The official checks below are free and go directly to PTA.
Method 1: SMS 668
- Open the messaging app on any Pakistani SIM.
- Type your 13-digit CNIC number without dashes, e.g.
3520212345671. - Send it to
668. - PTA replies with the number of active connections per operator registered on that CNIC.
Not sure your CNIC is typed correctly? Use our CNIC Format Checker to get the digits-only version — it never sends anything anywhere.
Method 2: cnic.sims.pk
- Go to cnic.sims.pk (PTA SIM Information System).
- Enter your CNIC number and complete the on-page verification.
- The site shows a count of connections per operator.
What the result tells you — and what it doesn't
PTA shows how many SIMs each operator has registered on your CNIC. It does not list the actual numbers. To find out which numbers are yours, visit the operator's franchise with your original CNIC. If the count is higher than you expect, read what to do about an unknown SIM on your CNIC.
Limits
PTA rules allow a limited number of SIMs per CNIC across all operators. If you have reached the limit, a new SIM cannot be issued until you block one you do not use.
Frequently asked questions
Is the 668 service free?
PTA describes the 668 SIM information service as free. Your operator may still apply its standard rules, so check with them if you are charged.
Can I see the actual numbers registered on my CNIC?
No. PTA only shows the count per operator. The operator can show you the numbers when you visit with your original CNIC.
Can I check someone else's CNIC?
You should only check your own CNIC. Looking up other people's personal records without consent is not something this site supports.
Does SimCheck.pk store my CNIC?
No. We do not have any form that sends CNICs anywhere. The checks happen on PTA's own SMS shortcode and website.
