SCO — the Special Communication Organization — is Pakistan’s fifth mobile network and the only state-owned telecom operator providing mobile services exclusively in Azad Jammu and Kashmir (AJK) and Gilgit-Baltistan. Millions of Pakistanis in these regions rely on SCO for mobile connectivity, yet no complete guide to checking SCO SIM owner details exists online.
This is that guide — Pakistan’s first and only dedicated resource for SCO SIM verification in 2026.
What Is SCO and Why Is It Different?
SCO (Special Communication Organization) operates under the Ministry of Defence of Pakistan and was established primarily to provide telecommunications infrastructure to Pakistan’s northern regions — AJK and Gilgit-Baltistan — where commercial operators historically had limited or no coverage.
| Feature | SCO | Jazz/Zong/Telenor/Ufone |
|---|---|---|
| Ownership | Government (Ministry of Defence) | Private / Foreign |
| Coverage area | AJK + Gilgit-Baltistan only | Nationwide |
| Number prefix | 0355–0357 | Various |
| Subscribers | 6M+ | 28M–82M each |
| 4G availability | Expanding | Nationwide |
| PTA regulation | Yes — same as all operators | Yes |
Critical point: SCO SIMs follow the exact same PTA biometric registration rules as all other operators. Every SCO SIM must be registered with a valid CNIC and biometric verification. SCO SIMs count toward your PTA limit of 5 SIMs per operator and 25 total across all networks.
SCO Number Prefixes — How to Identify an SCO Number
SCO mobile numbers in Pakistan use these prefixes:
| Prefix | Region |
|---|---|
| 0355 | AJK — Mirpur, Kotli, Bhimber areas |
| 0356 | AJK — Muzaffarabad, Rawalakot areas |
| 0357 | Gilgit-Baltistan — Gilgit, Skardu, Hunza |
If you receive a call from a number starting with 0355, 0356, or 0357, it is an SCO number from AJK or Gilgit-Baltistan.
