There are three things that irritate Pakistani mobile users more than anything else. The first is endless telemarketing calls from loan apps, property schemes, and insurance companies. The second is outright fraud calls — fake BISP prize announcements, fake bank warnings, and fake EasyPaisa alerts designed to steal your money. The third is the quiet worry: how many SIM cards are registered against my CNIC without my knowledge?
This guide covers all three with actual working solutions, not vague advice. Every method here is official, free, and confirmed working in 2026.
Part 1: Stop Telemarketing Calls and SMS — Register on DNCR
The Do Not Call Register (DNCR) is PTA's official system for blocking all legally-operating telemarketing companies from contacting your number. Once you are on this list, any registered business running marketing campaigns cannot legally include your number.
How to Register
Open your SMS app on any Pakistani network — Jazz, Telenor, Ufone, or Zong — and do the following:
Type: reg Send to: 3627
That is it. You will receive a confirmation message within a short while, and within one to two business days your number is removed from all legitimate telemarketing lists. If promotional calls and messages ever resume and you want to allow them again, text unreg to 3627 to reverse the registration.
This code works on every network and costs nothing beyond standard SMS rates.
Part 2: Report Fraud Calls and Scam Messages — SMS to 9000
The DNCR stops legal companies. It does nothing against scammers. For fraudulent calls, fake prize messages, and impersonation scams, PTA has a separate reporting system — and every report you send leads to a permanent SIM block on the scammer's number.
How to Report a Scam Number
Do not delete the fraud message. Keep it as evidence, then:
Step 1: Open a new SMS message.
Step 2: Type the scammer's mobile number, then a space, then paste the scam message you received.
Format: 03XX-XXXXXXX [paste the scam message here]
Step 3: Send to 9000.
PTA treats these reports seriously. The scammer's SIM is investigated and blocked permanently when sufficient reports are received. Your report may not see immediate results, but collectively these submissions shut down fraud operations. A small SMS charge applies for reporting to 9000.
For fraud calls you received but did not get a message from, you can also file a complaint directly at pta.gov.pk under the consumer complaints section, or call PTA's toll-free helpline at 0800-25625.
Part 3: Block a Specific Number on Your Phone
For an individual number — a harassing ex-contact, an annoying neighbour, or someone who simply will not stop calling — your smartphone's built-in tools are the fastest and most effective solution.
On Android
Open your recent calls, find the number, tap and hold it (or tap the three-dot menu), and select Block or Block/Report spam. On most Android phones (Samsung, Xiaomi, Infinix, Tecno) this also silences future calls automatically.
For a more powerful option, download Google Phone and Google Messages from the Play Store, set them as your default calling and messaging apps, then enable Spam Protection in the settings of each. These apps use Google's global spam database and automatically flag or silence known spam numbers before they even ring.
On iPhone
Go to Phone, then Recents, tap the information icon next to the number, scroll down, and tap Block this Caller. For SMS, open the conversation, tap the sender's name at the top, and select Block this Caller.
Part 4: Check How Many SIMs Are Registered on Your CNIC
This is one of the most important checks you can do for your own security. PTA allows a maximum of five SIM cards per CNIC across all networks. Identity misuse — where someone registers a SIM against your CNIC without your knowledge — is a real and common problem in Pakistan.
Check Via SMS
Type: Your 13-digit CNIC number (no dashes) Send to: 668
PTA's automated system replies with the total number of SIMs registered against your identity across all networks. If the number is higher than the SIMs you actually use, some have been registered fraudulently.
To have unauthorised SIMs blocked, visit the relevant network's franchise with your original CNIC and report the fraudulent registrations. The operator will deactivate them and update PTA's records. You may need to do this separately at each operator's franchise if the fake SIMs span multiple networks.
You can also run a quick CNIC identity check alongside your SIM check to make sure your overall CNIC status is clear and active.
Part 5: Block a Lost or Stolen Phone
If your phone has been stolen, blocking the handset prevents anyone from using it on any Pakistani network — even with a new SIM. PTA's Device Identification Registration and Blocking System (DIRBS) handles this.
Visit pta.gov.pk, go to the Lost and Stolen Device section, and submit your phone's IMEI number along with your CNIC and a description of the incident. Your IMEI number is printed inside the phone box or can be retrieved by dialling *#06# on your phone before it is stolen — worth noting it down somewhere safe in advance. You can also email [email protected] or call 0800-25625 for assistance.
The Short Version
To stop telemarketing: text reg to 3627. To report a scammer: send their number and the fraudulent message to 9000. To check how many SIMs are on your CNIC: text your CNIC number to 668. For individual number blocking: use your phone's built-in block feature or Google Phone. For a stolen handset: file at pta.gov.pk using your IMEI. Everything here is official, free, and works on all Pakistani networks.
