Pakistan has one of the most comprehensive legal frameworks in South Asia for prosecuting cyber harassment — yet millions of Pakistanis, particularly women, receive harassing calls and messages for months or years without taking legal action, primarily because they do not know their rights or the reporting process.
Harassment through phone numbers — unwanted calls, threatening messages, WhatsApp harassment, fake accounts created using someone’s SIM-linked identity — is directly connected to SIM registration. The phone number used to harass you is registered to a CNIC. That CNIC is traceable. The person behind the harassment is findable — if you know how to use Pakistan’s legal system to find them.
This guide covers Pakistan’s complete legal framework for cyber harassment linked to SIM and phone number abuse, the exact reporting process, what evidence to collect, and the specific protective measures that make you harder to harass through your SIM. This guide is written for victims, concerned family members, and anyone who wants to understand their rights.
Note on scope: This guide covers legal harassment reporting and protection measures only — not surveillance or tracking of others. If you are experiencing harassment, verify whether your CNIC data has been exposed (which may be how harassers obtained your number) at SimOwner.net.pk.
Pakistan’s Legal Framework for Cyber Harassment
PECA 2016 — The Primary Law
The Prevention of Electronic Crimes Act 2016 (PECA) is Pakistan’s primary legislation addressing cyber harassment. Multiple sections apply depending on the specific nature of the harassment:
Section 19 — Offences Against Dignity of a Natural Person:
This section specifically targets content that is “false and obscene” and is used to “harass” a person. It covers:
- Sending repeated unwanted messages with intent to harass
- Publishing or transmitting content that harms someone’s dignity
- Creating fake online profiles to harass a person
Penalty: Imprisonment up to 3 years or fine up to Rs. 1,000,000 or both.
Section 20 — Offences Against Modesty of a Natural Person and Minor:
This section covers:
- Publishing or transmitting intimate images without consent
- Content that outrages modesty
- Material involving minors in a harmful context
Penalty: Imprisonment up to 7 years or fine up to Rs. 5,000,000 or both.
Section 21 — Electronic Fraud:
Applicable when harassment is accompanied by financial demands or threats linked to financial coercion.
Section 17 — Unauthorized Interception:
Applicable when the harasser is intercepting private communications to obtain material for harassment.
Why SIM Registration Matters for Harassment Cases
Every phone number used for harassment in Pakistan is (or should be) registered to a CNIC through Pakistan’s mandatory SIM registration system. This means:
- The harasser has a traceable identity — their CNIC is linked to their number in PTA’s SVMS
- FIA can subpoena operator records — call logs, message records, and registration details
- NADRA MBVS records — the biometric verification at SIM registration creates a reliable identity link
In harassment cases where the harasser uses multiple SIM cards or frequently changes numbers, FIA can trace each number back to its registered CNIC through the operator records. Pakistan’s mandatory biometric SIM registration makes anonymous harassment technically impossible — harassers can be identified even when using “burner” SIMs.
Types of SIM-Linked Harassment in Pakistan
Type 1 — Persistent Unwanted Calls
Repeated calls from one or multiple numbers — threatening, obscene, or simply persistent — with intent to disturb or intimidate. This is the most common form of harassment reported to FIA Cybercrime Wing.
Type 2 — WhatsApp Harassment
Messages, voice notes, images, or calls via WhatsApp from known or unknown numbers. WhatsApp is linked to phone numbers registered to CNICs — WhatsApp provides records to FIA upon legal request.
Type 3 — Fake Account Creation Using Victim’s Number
A harasser creates social media accounts using the victim’s phone number or impersonating the victim — often using personal information obtained through CNIC breach databases or relationship access. This intersects with identity fraud under PECA Section 16.
Type 4 — Threatening Messages
Explicit threats of violence, sexual harm, or property damage transmitted via SMS, WhatsApp, or other digital channels from a SIM-registered number.
Type 5 — Non-Consensual Intimate Image Distribution
Sharing intimate images without the subject’s consent — a serious PECA Section 20 violation carrying the highest penalties in Pakistan’s cyber harassment framework.
Type 6 — Financial Sextortion
Threatening to distribute intimate material unless money is paid — combining PECA Sections 20 and 21. This is increasingly documented in FIA Cybercrime cases.
How Harassers Obtain Your Number — And How to Stop Them
Understanding how a harasser got your phone number helps you cut off their information source and protect yourself going forward:
From CNIC breach databases: As detailed in our CNIC Data Breach Pakistan guide, Pakistani subscriber data including phone numbers has been exposed in multiple large-scale breaches. Harassers can purchase your phone number paired with your name and address from these breach databases.
From social media: Phone numbers visible on Facebook profiles, WhatsApp status, or business pages are harvested by harassment networks.
From shared contacts: In relationship-based harassment (domestic situations, workplace situations), the harasser likely obtained the number directly.
From public registrations: Business registration, property documents, and other public records sometimes contain phone numbers.
Protective measures:
- Remove your phone number from all public social media profiles
- Use a separate public number for business listings that does not connect to your financial accounts
- Implement the dual SIM security strategy — a private number for personal/financial use
Collecting Evidence — What FIA Needs
Before filing any complaint, collect and preserve evidence. FIA Cybercrime investigations require documented evidence — verbal descriptions alone are insufficient.
Essential Evidence to Collect
Screenshots with timestamps: Every harassing message, call record, WhatsApp conversation, or social media interaction. Ensure the timestamp and phone number/profile are clearly visible in every screenshot.
Call log records: Your phone’s call log showing the harassing number(s), date, time, and duration of calls. Screenshot or export this.
WhatsApp exports: In WhatsApp, open the chat with the harasser → three dots → More → Export Chat. Save this export — it contains all message content with timestamps.
Any identifying information from the harasser’s profile: Profile photo, name, location information, other phone numbers they mention.
Pattern documentation: A simple written record showing the pattern — “Received 12 calls on [date] between 10pm and 2am from number [XXXXX]” — demonstrates systematic harassment rather than a one-time incident.
Evidence Preservation Rules
Never delete harassing messages — even if you want to. Delete means evidence gone. Move them to a separate folder, mute the contact, but preserve the messages.
Back up evidence to multiple locations: Email screenshots to yourself, save to cloud storage, and keep a physical printed copy. FIA investigations can take time — you need evidence that survives a phone loss or change.
Do not share evidence publicly before the legal case is resolved — sharing screenshots on social media can compromise the investigation and potentially create legal complications.
Step-by-Step Reporting Process
Step 1 — FIA Cybercrime Wing Complaint (Primary Channel)
Online filing: complaint.fia.gov.pk — available 24/7
What to include:
- Your CNIC number and contact information
- The harassing phone number(s) — every number used
- Network operator for each harassing number (if identifiable from number prefix)
- Timeline of harassment — start date, frequency, escalation
- Nature of harassment — threatening, obscene, persistent calls, fake accounts
- Evidence attached — screenshots, call logs, WhatsApp exports
- Any known identity of harasser (if known relationship)
PECA sections to cite:
- Section 19 (dignity offences — harassment) — always cite
- Section 20 (modesty offences — if intimate content involved)
- Section 17 (interception — if private communications were accessed)
After filing: You receive a complaint reference number. FIA assigns an investigating officer. Initial response within 24–72 hours for urgent harassment cases.
Step 2 — PTA Complaint for Number Blocking
File at complaint.pta.gov.pk specifically requesting the harassing number(s) be blocked at the network level.
PTA has authority to direct network operators to block numbers used for documented harassment. While this does not prevent the harasser from getting a new SIM, it disrupts their current harassment campaign.
What to include: Your complaint, the harassing numbers, FIA complaint reference number (if already filed).
Step 3 — Network Operator Report
Call the network operator whose SIM is being used for harassment and report the number:
| Network | Report Line |
|---|---|
| Jazz | 111-225-111 |
| Zong | 310 |
| Telenor | 345 |
| Ufone | 333 |
Tell the agent: “I am reporting number [harassing number] for harassment. I have filed an FIA complaint, reference [number]. Please flag this number and restrict outgoing communications pending investigation.”
Network operators can add flags to accounts under investigation and cooperate with FIA data requests.
Step 4 — Police FIR
File an FIR at your local police station for particularly serious harassment — threats of violence, sextortion, or any harassment that creates fear for physical safety.
PECA offences are cognizable — police must register the FIR. If refused, follow the escalation process outlined in our FIR for SIM Fraud guide — the same escalation applies here.
Include in FIR: All harassing numbers, FIA complaint reference, evidence summary, and the specific PECA sections violated.
Step 5 — Pakistan Electronic Media Regulatory Authority (PEMRA) — If Broadcast
If harassment involves broadcast media or publicly distributed content, PEMRA has additional jurisdiction. This applies to a minority of harassment cases but is relevant for public figures or when harassment involves radio/TV.
Protecting Your SIM and Identity From Harassment
Beyond legal action, these practical measures reduce your vulnerability to ongoing SIM-linked harassment:
Immediate Protective Measures
Block the harassing number: On your phone directly (Settings → Phone → Blocked Contacts), and via WhatsApp (chat → Block). This does not stop a determined harasser from getting a new number, but it stops the immediate channel.
Enable WhatsApp privacy settings:
- Settings → Privacy → Last Seen: “My Contacts”
- Settings → Privacy → Profile Photo: “My Contacts”
- Settings → Privacy → Status: “My Contacts”
- Settings → Privacy → Groups: “My Contacts” (prevents being added to unwanted groups)
- Settings → Privacy → Calls: Silence Unknown Callers
Change your number (if appropriate): If harassment is persistent and from unknown sources, getting a new number and carefully managing who receives the new number may be the most effective practical solution. Complete a formal SIM ownership transfer process — do not simply abandon the old number as it remains on your CNIC.
Medium-Term Protection
Audit your digital footprint: Remove your phone number from social media profiles, business listings, and any public-facing online presence. The less visible your number is publicly, the harder it is for harassers to find or distribute it.
Two-number strategy: Use one number for private personal use and a separate number for public/business contact. This way, if the public number becomes a harassment target, you can change it without disrupting your private life.
Monitor CNIC SIM registrations: Using the SimOwner.net.pk live tracker, confirm no new unauthorized SIMs appear on your CNIC. In some harassment cases, the harasser attempts to register SIMs in the victim’s name to monitor their activity or create additional harassment channels.
Support Resources for Harassment Victims in Pakistan
FIA Cybercrime Wing: complaint.fia.gov.pk — primary reporting channel PTA Helpline: 0800-55055 (toll-free) National Commission on the Status of Women (NCSW): ncsw.gov.pk Digital Rights Foundation Cyber Harassment Helpline: 0800-39393 (toll-free, Monday–Friday 9am–5pm) — provides counseling, legal guidance, and case support specifically for cyber harassment victims
The Digital Rights Foundation helpline specifically supports cyber harassment victims in Pakistan and can provide guidance on evidence collection, FIA complaint filing, and navigating the legal process. Their lawyers assist with PECA cases.
What Happens After the FIA Complaint
Understanding the investigation process manages expectations and helps you support the investigation:
Week 1–2: FIA reviewing complaint, assigning investigation officer.
Week 2–4: FIA issues data preservation orders to network operator(s) — requiring them to preserve call records, message logs, and registration data for the harassing number(s).
Month 1–3: FIA requests subscriber data from operator via legal process — obtaining the CNIC registered to the harassing number and NADRA MBVS verification records.
Month 2–6: FIA investigators may contact you for additional information or statement. Cooperate fully and provide any additional evidence.
Prosecution: If sufficient evidence exists and harasser is identified — FIA/police file charges under relevant PECA sections. Cases are heard in specialized cyber crime courts established under PECA 2016.
Timeline reality: FIA cybercrime investigations vary enormously in timeline — from weeks (for clear-cut cases with identified harassers) to months (for cases involving anonymous SIMs or multiple numbers). Persistence in following up with your assigned FIA investigation officer matters.
Special Considerations for Women Victims
Pakistan’s cyber harassment landscape disproportionately affects women. PECA 2016 recognizes this — Section 20’s higher penalties reflect the severity of gender-targeted harassment. Additional resources:
Gender-sensitive FIA units: FIA’s Cybercrime Wing includes female investigation officers for cases where the victim prefers to report to a female officer. Request this when filing.
NCSW support: The National Commission on the Status of Women can support cases involving gender-based cyber harassment and can apply institutional pressure on FIA and PTA for faster investigation responses.
Keeping family involvement minimal during initial reporting: For harassment involving intimate content, victims may prefer to file independently before involving family members. The FIA complaint process can be completed by the victim alone, without family presence.
Frequently Asked Questions
Q: The harasser keeps changing numbers. Can FIA still trace them?
A: Yes — each new number is registered to a CNIC via NADRA MBVS biometric verification. Even if a harasser uses 5 different numbers sequentially, each traces back to a registered identity. The pattern of numbers used in harassment can all be traced to the same CNIC through the SVMS registration database.
Q: What if the harasser is using a foreign number (+1, +44)?
A: Foreign numbers used for harassment in Pakistan are harder to trace through PTA’s domestic system. However, WhatsApp and major platforms cooperate with FIA requests through mutual legal assistance treaties. FIA can still request WhatsApp records for foreign-number accounts. File the FIA complaint — indicate the foreign number and FIA will determine the appropriate international channel.
Q: Can I find out who owns a harassing number?
A: As an individual, you cannot directly access SIM registration data for a number you do not own. The 668 service checks your own CNIC’s SIMs — not another person’s registration. FIA’s investigation authority allows them to subpoena this information from the network operator. This is why filing the FIA complaint is the appropriate channel for obtaining harasser identification.
Q: The harasser is someone I know personally. Does reporting still make sense?
A: Yes — PECA applies regardless of the victim-harasser relationship. In domestic or relationship-based harassment cases, FIA and police are required to investigate. Document the harassment thoroughly before reporting if you are concerned about evidence being disputed. Organizations like the Digital Rights Foundation Cyber Harassment Helpline provide case-specific guidance for relationship-based harassment situations.
Q: My harasser threatened to share intimate images if I report. What should I do?
A: This threat is itself a criminal offence under PECA Section 20 (sextortion). Do not comply with demands. Report immediately to FIA at complaint.fia.gov.pk — specifically cite “sextortion/non-consensual intimate image threat” in your complaint. FIA prioritizes these cases and can issue rapid preservation orders to platforms to prevent distribution. The Digital Rights Foundation helpline (0800-39393) has specific protocols for these cases.
Q: Can reporting harassment lead to my own number being exposed?
A: The FIA complaint process does not publicly expose your phone number. Your contact information in the complaint is for FIA use only, not published. Ask FIA about confidentiality procedures if this is a concern for your specific situation.
