SCO — the Special Communication Organization — is Pakistan’s fifth mobile network operator, serving one of the most strategically important and geographically distinctive regions in the country: Azad Jammu and Kashmir (AJK) and Gilgit-Baltistan (GB). While Jazz, Zong, Telenor, and Ufone dominate Pakistan’s major urban markets, SCO is the primary — and in many remote mountainous areas, the only — mobile network serving millions of Pakistani citizens in AJK and GB.
Despite being smaller in subscriber count than the four major operators, SCO SIM registrations fall under the same PTA regulatory framework, the same biometric verification requirements, and the same CNIC-linked registration system as all other Pakistani networks. This means SCO subscribers have the same rights, the same verification tools, and the same fraud risks as any other Pakistani mobile user.
This guide covers every official method for checking SCO SIM owner details — how to verify your SCO SIM is correctly registered on your CNIC, how to check for unauthorized SCO SIM registrations, and what to do if you discover a problem.
Quick Answer: To check all SIMs on your CNIC including SCO, send your 13-digit CNIC number (no dashes) to 668 via SMS. SCO SIMs registered on your CNIC will appear in the reply alongside any Jazz, Zong, Telenor, or Ufone SIMs — completely free.
What Is SCO and Who Does It Serve?
The Special Communication Organization was originally established to provide telecommunications infrastructure in AJK and Gilgit-Baltistan — regions that present some of the world’s most challenging terrain for network deployment. SCO’s mission combines commercial mobile services with a strategic national security dimension, as these border regions require reliable communication infrastructure for both civilian and defense purposes.
SCO’s operational scope:
- Azad Jammu and Kashmir (AJK): Covering Muzaffarabad, Mirpur, Rawalakot, Bagh, Kotli, Haveli, Sudhnoti, Poonch, and all other AJK districts
- Gilgit-Baltistan (GB): Covering Gilgit, Skardu, Hunza, Nagar, Ghizer, Ghanche, Astore, Diamer, and Shigar — including some of the world’s most remote high-altitude communities
SCO number prefixes: SCO mobile numbers use the following prefixes:
- 0320 — SCO standard prefix
- 0321 — SCO secondary prefix
Important: The 0321 prefix was historically associated with Mobilink/Jazz in some regions. In AJK and GB, however, 0321 numbers may be SCO numbers. The 668 reply clearly labels the network for each number — always trust the network label over the prefix when determining the operator.
Why SCO SIM Verification Matters — Specific Risks for AJK and GB Residents
SCO SIM fraud follows the same patterns as fraud on other networks but has some region-specific characteristics worth understanding:
Remote area franchise compliance: SCO’s network includes many franchise points in extremely remote areas — high-altitude villages, border communities, and areas with limited regulatory oversight. PTA compliance monitoring in these locations has historically been more challenging than in urban centres. This can create opportunities for fraudulent SIM registrations where biometric verification is less rigorously enforced.
Lower monitoring awareness: Many SCO subscribers in remote AJK and GB communities are less aware of the 668 monitoring tool or the 5-SIM CNIC limit. Criminals targeting these communities exploit this awareness gap — registering SIMs on rural CNICs that are less likely to be regularly monitored.
Migration and overseas worker vulnerability: A significant proportion of AJK’s population works abroad (particularly in the UK). Their Pakistani CNICs — which retain the same SIM registration capacity whether the holder is in Pakistan or abroad — can be targeted for unauthorized SCO SIM registrations while the holder is out of the country.
Cross-network fraud: Criminals often combine an SCO SIM registration (less monitored) with SIMs on major networks to create multi-SIM fraud operations that are harder to trace across operator databases.

Method 1: Check SCO SIM Owner Details via 668 SMS
The 668 service is the universal Pakistani SIM verification tool — it covers all five networks including SCO with equal accuracy and real-time data.
Step-by-Step:
Step 1: Open your phone’s SMS application on any Pakistani SIM — this does not need to be an SCO SIM. 668 works from Jazz, Zong, Telenor, Ufone, and SCO SIMs equally.
Step 2: Create a new message addressed to: 668
Step 3: In the message body, type your 13-digit CNIC (or AJK CNIC/NICOP if applicable) — no dashes, no spaces.
Step 4: Send the message. It is free from all networks.
Step 5: Receive the reply within 30–60 seconds.
Step 6: Look for SCO entries in the reply — they will be labeled as “SCO” and show numbers starting with 0320 or 0321.
Understanding AJK CNIC Numbers in 668:
AJK residents hold Pakistani CNICs with a specific district prefix pattern:
- AJK CNIC numbers typically begin with 82 or 83 (AJK district codes)
Gilgit-Baltistan residents:
- GB CNIC numbers typically begin with 74 or 75 (GB district codes)
These CNICs work identically to all other Pakistani CNICs in the 668 system — enter all 13 digits exactly as shown on your card, no dashes.
What to Do If You Find an Unauthorized SCO SIM:
- Screenshot the 668 reply immediately
- Call SCO helpline 1236 (from an SCO SIM) or the general contact number
- Call PTA at 0800-55055 to file a formal complaint
- Visit the nearest SCO Customer Service Centre with your original CNIC for biometric-verified blocking
- File an FIR at your local police station in AJK or GB
Method 2: Check SCO SIM Details via cnic.sims.pk
PTA’s official web portal covers all five networks including SCO:
Steps:
Step 1: Open any browser on any device (phone, tablet, computer).
Step 2: Navigate to: cnic.sims.pk
Step 3: Enter your 13-digit CNIC or AJK/GB CNIC number in the field provided (no dashes).
Step 4: Complete the CAPTCHA security verification.
Step 5: Click Submit.
Step 6: The portal displays all SIMs registered under your CNIC — SCO SIMs are clearly labeled.
Step 7: Screenshot the results for documentation.
Particular Value for AJK and GB Users:
For AJK residents in the UK diaspora or GB residents working in other countries, the cnic.sims.pk portal is the primary method for monitoring their Pakistani CNIC SIM registrations from abroad — since 668 is a local short code and cannot be accessed from foreign networks.
Method 3: Check SCO SIM Details via SCO Helpline (1236)
SCO operates a customer care helpline for SIM account inquiries and fraud reporting:
Steps:
Step 1: Dial 1236 from your SCO SIM — this call is free from SCO numbers.
Step 2: Follow the IVR options for your preferred language and service category.
Step 3: When connected to an SCO representative, state:
“I want to verify the registration status of my SCO SIM and check whether any unauthorized SCO SIM has been registered on my CNIC.”
Step 4: Provide your CNIC number and SCO SIM number for identity verification.
Step 5: The representative confirms your SIM’s BVS status and registration details.
For unauthorized SCO SIM reporting: Provide the unauthorized number and your CNIC. Request immediate blocking. Note the complaint reference number.
SCO helpline limitations: SCO’s helpline infrastructure is smaller than major operators — wait times can be longer, especially during high-traffic periods. If the helpline is unavailable, use the PTA complaint portal (complaint.pta.gov.pk) as an alternative.
Method 4: Check SCO SIM Details at SCO Customer Service Centre
For the most complete SCO SIM owner verification — including registration dates and franchise locations:
What to Bring:
- Original CNIC or NICOP (biometric required — no photocopies)
- Your SCO SIM card
SCO Customer Service Centre Locations:
SCO operates Customer Service Centres in major AJK and GB cities:
| Region | Key Locations |
|---|---|
| AJK | Muzaffarabad (HQ), Mirpur, Rawalakot, Bagh, Kotli, Bhimber, Haveli |
| Gilgit-Baltistan | Gilgit (HQ), Skardu, Hunza (Aliabad), Ghizer (Gahkuch) |
For remote communities: SCO maintains franchise points in smaller towns and villages. For fraud complaints specifically, attending a major city Customer Service Centre is recommended for faster resolution.
What the SCO Franchise Terminal Shows:
- All SCO SIMs registered on your CNIC
- Registration date and time for each SIM
- Location (franchise) where each SIM was originally registered
- BVS (Biometric Verification) status
- Account history
Method 5: SCO SIM Verification via USSD
SCO provides basic USSD self-service for account and SIM information:
SCO USSD Codes for Account Verification:
| Code | Function |
|---|---|
*1# | Check your own SCO number |
*100# | SCO account balance |
*310# | SCO account information menu |
1236 | Free SCO helpline |
Note: SCO’s USSD system is less extensive than Jazz, Zong, Telenor, or Ufone — reflecting SCO’s smaller operational scale. For account verification beyond basic balance checks, the franchise visit or 668 check provides more complete information.
SCO SIM Registration — Biometric Requirements and BVS
SCO SIM registrations follow the same biometric verification requirements as all other Pakistani operators under PTA’s mandate:
BVS requirement: Every SCO SIM must be biometrically linked to a valid CNIC via NADRA’s fingerprint database.
BVS verification terminal: SCO franchises use the same NADRA-connected biometric terminals as Jazz, Zong, Telenor, and Ufone.
BVS compliance history: SCO’s biometric compliance rate in remote areas has been an area of PTA audit attention. If your SCO SIM was registered before 2015 or in a very remote franchise location, it may have a BVS pending status requiring re-verification.
How to check BVS status for SCO SIM:
- Call SCO helpline 1236 and ask for BVS status check
- Visit any SCO Customer Service Centre for in-person biometric verification
Why BVS matters: An SCO SIM with BVS Pending status is at risk of PTA blocking enforcement. Complete your biometric verification at the nearest SCO franchise proactively.
SCO NICOP and Overseas AJK Community
AJK has one of the highest overseas Pakistani populations per capita in the world — primarily in the United Kingdom. Many UK-based Pakistanis of AJK origin hold both Pakistani CNIC and NICOP documents. Here is how this intersects with SCO SIM management:
NICOP for SCO SIM registration: NICOP is fully accepted for SCO SIM registration — the same as with any other Pakistani operator. AJK NICOP holders can register SCO SIMs during Pakistan visits.
Monitoring from the UK: UK-based AJK community members should use cnic.sims.pk monthly to check both their CNIC and NICOP numbers for unauthorized SCO SIM registrations — since remote AJK community CNICs are specifically targeted by fraudsters who know these individuals are less likely to monitor their SIM records.
The 180-day rule for SCO SIMs: SCO SIMs held by overseas AJK residents left in Pakistan face the same 180-day inactivity deactivation risk as SIMs on other networks. Arrange for a trusted family member to make one USSD query or call from the SCO SIM every 90 days.

SCO and the 5-SIM CNIC Limit
PTA’s 5-SIM limit per CNIC applies equally to SCO registrations — SCO SIMs count toward your total 5-SIM quota exactly the same as Jazz, Zong, Telenor, or Ufone SIMs.
What this means practically:
If your 668 check shows:
- 2 Jazz SIMs
- 1 Zong SIM
- 1 Telenor SIM
- 1 SCO SIM
You are at your maximum of 5 SIMs. You cannot register any new SIM (on any network) until one of these is deactivated.
If an unauthorized SCO SIM has consumed one of your 5 slots, it has effectively prevented you from registering a legitimate SIM anywhere in Pakistan. This makes unauthorized SCO SIM registration doubly damaging — it is both a fraud risk and a practical obstruction of your mobile registration rights.
Frequently Asked Questions — SCO SIM Owner Details Pakistan
Q: Does 668 show SCO SIMs as accurately as Jazz or Zong SIMs?
A: Yes. 668 queries PTA’s national CSRS database which includes all five operators equally. SCO SIM registrations appear in the 668 reply with the same accuracy and the same near real-time update speed as any other operator.
Q: Can I register a Jazz or Zong SIM as an AJK resident?
A: Yes. AJK and GB residents can register SIMs on any Pakistani operator — Jazz, Zong, Telenor, Ufone, or SCO. The 5-SIM limit applies to all registrations combined regardless of which operator.
Q: I live in Gilgit-Baltistan. Can I use 668 from my SCO SIM?
A: Yes. 668 works from SCO SIMs in Gilgit-Baltistan and AJK exactly as it does from any other Pakistani network. Send your CNIC number to 668 from your SCO SIM — the call routes through PTA’s system normally.
Q: SCO’s helpline (1236) is not answering. What should I do?
A: Use PTA’s complaint portal at complaint.pta.gov.pk to file your complaint — it is available 24/7. Or call PTA at 0800-55055 (Monday–Saturday, 9 AM–5 PM). PTA has regulatory authority over SCO and can compel action.
Q: Can Overseas Pakistanis from AJK check their SCO SIM status from abroad?
A: Yes — using cnic.sims.pk (web portal) which works from any country with internet. This is the primary recommended method for the UK-based AJK diaspora.
Q: Is there a USSD code to check all my SIMs on SCO specifically?
A: SCO’s USSD system shows your own SCO SIM details only — not other network SIMs on your CNIC. For the full cross-network picture, always use 668 or cnic.sims.pk.
Q: Does PECA 2016 apply to SCO SIM fraud in AJK and GB?
A: Yes. PECA 2016 applies nationally — including AJK and GB. Unauthorized SCO SIM registration is a criminal offence under Section 16 carrying up to 3 years imprisonment and Rs. 1 million fine.
Q: SCO’s coverage is poor in my area. Can I port my SCO number to Zong via 667?
A: Yes. MNP (Mobile Number Portability) via 667 works for SCO SIMs — you can port your SCO number to any of the four major operators while keeping your existing number.
