SIM Check SMS Codes

Complete SMS Code Reference

Every SIM check SMS code in Pakistan sits in one of four families: PTA's CNIC count (668), your own SIM's registration check (667), network identification (76367), and per-operator biometric or own-number codes (6001, 7751, 7911 and the USSD codes). The table above is the quick reference; the sections below explain what each code actually replies with and what it cannot do.

Code by Code: What Each Check Replies

668: SIM Count on Your CNIC

SMS your 13-digit CNIC, without dashes, spaces or extra words, to 668. The reply lists how many SIMs are registered against your CNIC, company by company. It shows counts only: PTA has published no sample reply, so treat any screenshot of a "668 reply" listing phone numbers or names with suspicion. Charges may apply per PTA's notice of 31 December 2025, so do not resend in a loop. The same count is free at cnic.sims.pk, PTA's official SIM Information System. Full walkthrough: how to check SIMs on your CNIC.

667: Registration of the SIM That Sends the Message

Text MNP to 667 from the SIM you are holding. The reply shows that SIM's mobile number, registered name, CNIC and SIM number. The service exists for mobile number portability, which is why it returns your own record: you must be holding the SIM for it to send. It cannot check a SIM sitting in someone else's phone. If the reply shows a name or CNIC that is not yours, contact the operator to correct the record.

76367: Which Network a Number Is On

Text N, a space, then an 11-digit number (for example N 03001234567) to 76367. The reply names the network the number currently uses, which matters because mobile number portability breaks the link between a prefix and its original network. Price per the cnic.sims.pk listing: Rs 2 plus tax. It shows the network and nothing else, never the subscriber; mobile number details covers how prefixes and porting interact.

6001, 7751 and 7911: Biometric Status by Operator

These confirm whether a SIM has completed biometric verification, which has been mandatory since 2015 and has run through MBVS (two random fingers checked against NADRA records) since December 2022. Jazz: SMS your CNIC to 6001. Telenor: SMS your CNIC to 7751. Zong and Ufone: SMS V to 7911; Ufone also offers *336# option 1. None of these counts SIMs or reveals owners; they answer one yes-or-no style question about the SIM you are using.

*99#, *8#, *8888#, *780*3#, *414#: Your Own Number

USSD codes, dialled rather than texted, that read your own number back from the network: *99# on Jazz, *8# on Zong, *8888# on Telenor, *780*3# on Ufone and *414# on SCO. They involve no third party and reveal nothing about anyone else. Your phone's SIM settings usually show the same number.

8484 and *#06#: IMEI and Device Status

Dial *#06# (free) to display your phone's IMEI, then SMS that IMEI to 8484 to check its PTA registration status via PTA, or verify the result at the DIRBS portal. This is about devices, not SIMs or subscribers.

Help Channels: 0800-55055, 1799, RAABTA

PTA's helpline 0800-55055 is toll-free and handles SIM complaints; you can also file at complaint.pta.gov.pk. The NCCIA's 1799 line is for cybercrime, including identity misuse under PECA 2016 (see PECA 2016 and SIM ownership). PTA's RAABTA assistant answers general telecom questions on WhatsApp at 0315-0055055.

Important: Do Not Confuse These Codes

• 668 counts SIMs on your CNIC. It does not show phone numbers or owner names.
• 667 checks the registration of the SIM that sends the message. It does not check someone else's SIM.
• 76367 shows which network a number is on. It does not show the owner.
• 6001/7751/7911 check biometric verification status, not SIM count.

Network-Specific Codes

Troubleshooting: When a Code Does Not Work

No reply arrives

Open the sent message first. The usual causes are a dash or space inside the CNIC, an extra word before the number, or sending to the short code from the dialler instead of Messages. Check the SIM has balance, since some checks are charged. Send once more; if nothing still arrives, stop resending (each message may be charged) and switch to the free cnic.sims.pk website, which answers the same count question.

"Wrong format" or a reply that names the error

Short codes parse strict formats. For 668 the body must be the thirteen digits alone; PTA's FAQ and its releases of 10 November 2023 and 31 December 2025 both say no dashes. For 667 the body must be exactly MNP, sent from the SIM you want checked. For 76367 it must be N, one space, then the full 11-digit number. Correct one thing at a time rather than rewriting the whole message.

The code works but the answer is not what you wanted

That is usually the right reply to the wrong question. 668 will never list numbers; it counts. 76367 will never name an owner; it names a network. The boundary is deliberate: no official SMS code discloses another person's details, and unauthorised access to identity information is an offence under PECA 2016.

Charged for a check you did not mean to run

Charges vary by network and code, and PTA's 31 December 2025 notice says charges may apply to the 668 SMS. Confirm your network's SMS rate before sending, and prefer the free website for repeat checks.

SIM Check Codes: The Bottom Line

The complete set of SIM check SMS codes comes down to four questions you can lawfully ask: how many SIMs sit on my CNIC (668 or cnic.sims.pk), who does the SIM in my hand belong to (MNP to 667), which network is a number on today (N to 76367), and has my SIM passed biometric verification (6001, 7751 or 7911). Everything else on the reference table is device status or a help line.

Your next step: save 668 and cnic.sims.pk as your routine. Run the CNIC count once a quarter, compare it against your own SIM list, and if any company's count is too high, follow the disowning process the same week.
