Frequently asked questions
How can I check how many SIMs are on my CNIC?
Send your 13-digit CNIC without dashes to 668 by SMS, or visit PTA's cnic.sims.pk. PTA replies with the count per operator.
Can SimCheck.pk show who owns a number?
No. Owner details are private and protected. We only provide official methods for checking your own SIMs and general number information.
Are the tools on this site safe to use?
Yes. Every tool runs in your browser. CNICs, IMEIs and phone numbers are never sent to a server or saved.
How do I check if a phone is PTA approved?
SMS the 15-digit IMEI to 8484 or check it on dirbs.pta.gov.pk. Our IMEI validator can catch typos first.
Is SimCheck.pk an official PTA website?
No. We are an independent information site and are not affiliated with PTA, NADRA or any operator. We link to official services.
What is the 668 SIM check?
An SMS service run by PTA. Send your CNIC (13 digits, no dashes) to 668 to receive the count of SIMs per operator.
How many SIMs can be registered on one CNIC?
PTA sets an overall cap across all operators and a cap per operator. Ask your operator for the current limits.
What should I do about a SIM I didn't register?
Visit that operator with your original CNIC, ask for it to be blocked, and report it to PTA if not resolved. See our unknown SIM guide.
Why does the network checker show the wrong network?
Numbers can be ported between operators and keep their prefix. The checker shows the original operator.
What does a valid IMEI result mean?
Only that the format and checksum are correct. Use DIRBS or SMS 8484 for PTA status.
How do I find my own number?
Jazz *99#, Zong *2#, Ufone *780*3#, Telenor *8888#. See the own number check page for more methods.
Will anyone call me to update biometrics?
Treat such calls as fraud. Operators, PTA and NADRA do not ask for OTPs or fingerprints by phone.
