When you hold a physical SIM in your hand — whether it came with a second-hand phone, was inherited from a family member, or arrived as a mystery in an old SIM tray — you have the legal right to verify who it is registered to. The SIM Information Database tool on SimOwner is a free educational resource explaining how Pakistan's official SIM verification system answers exactly this question, using the PTA-approved 667 MNP method that works across every Pakistani network.
This tool is fundamentally different from a CNIC-based audit. The CNIC Information Check starts from your identity and lists all SIMs tied to it. The SIM Information Database approach starts from a single SIM in your possession and returns the registered owner of that one number. Both methods query the same official PTA-NADRA registry — but they answer different questions, and Pakistani consumers need to know which one to use when.
What Is Pakistan's SIM Information Database?
Pakistan's national SIM information database is officially called the Subscriber Verification Management System (SVMS). It is jointly maintained by the Pakistan Telecommunication Authority (PTA) and NADRA, and it stores the complete registration record of every active mobile connection in the country across Jazz, Telenor, Zong, Ufone, and SCOM networks. The database links each SIM to a 13-digit CNIC via biometric fingerprint verification at activation.
This is the only legitimate SIM information database in Pakistan. Every other website, app, or "Pak SIM data" service advertising similar capability is illegal under PECA 2016 — PTA has blocked 1,300+ such platforms, FIA Cybercrime Wing actively prosecutes operators, and PKCERT's September 2025 advisory confirmed many distribute Raccoon and RedLine malware to harvest user data.
The SVMS does not allow public bulk searches. What it does allow — and what this tool teaches you to use — is targeted self-verification through three official channels: 667 for single-SIM lookup, 668 for CNIC-wide audit, and cnic.sims.pk for online portal access.
What the 667 MNP Method Reveals
The 667 service — operated by Pakistan's Mobile Number Portability (MNP) system — returns the following information when you query a SIM that is physically inserted in your phone:
- Registered Owner Name — the full legal name as recorded at SIM activation
- Masked CNIC Number — last digits visible for verification (full CNIC is protected)
- Network Operator — Jazz, Telenor, Zong, Ufone, or SCOM (especially useful after MNP porting where the prefix no longer matches the current carrier)
- Activation Date — when NADRA's biometric verification system authorized the SIM
- Status — active, suspended, or pending re-verification
The response arrives within 30 seconds via SMS. Cost is negligible — typically Rs. 0.50 to 2.00 depending on your operator's SMS rate, and often free on monthly packages.
3-Step Guide to Verify a SIM in Your Phone
According to Sara Khan, SimOwner's lead telecom researcher, the 667 MNP method is the fastest legal way to confirm SIM ownership of a number you physically hold. The process is identical regardless of which Pakistani telecom operator issued the SIM:
- Insert the SIM you want to verify into your phone. The SIM must be physically active in the device — this is a fundamental legal requirement that prevents remote lookups of someone else's number.
- Open your SMS app and type
MNP(capital letters, exactly as written). Send the message to the shortcode 667. Do not dial 667 as a voice call — the service responds only to SMS. - Wait for the official reply within 30 seconds. The SMS will contain the registered owner's full name, partially masked CNIC, the active network operator, and the SIM activation date. If no reply arrives within 5 minutes, ensure full signal and retry once more.
That is the entire procedure. No website signup, no payment, no third-party app. Every Pakistani citizen has the legal right to use this service for any SIM in their physical possession — under PTA guidelines and PECA 2016, this falls squarely within permitted self-verification.
When You Should Use the 667 Method
The SIM Information Database lookup via 667 is the right tool for several specific situations Pakistani consumers commonly face:
- Buying a second-hand phone — verify the SIM inside before transferring it to your CNIC
- Inherited SIMs from a deceased family member — confirm registration before initiating transfer paperwork
- Suspicious SIMs found in old phones or drawers — identify who registered them before deciding to keep or block
- Verifying your own SIM — confirm your name appears correctly in the registry after re-verification or biometric refresh
- Pre-purchase due diligence on bulk SIM purchases — businesses verifying employee-issued SIMs
- Confirming a SIM transfer was processed correctly — after visiting a franchise to change ownership
667 vs 668 — Which Method Should You Use?
Both methods query the same SVMS registry but answer different questions. Use this decision table to pick correctly:
| Your Situation | Correct Method |
|---|---|
| You have a CNIC and want to know all your SIMs | 668 — send CNIC to 668 |
| You have one SIM in hand and want to know its owner | 667 — send MNP to 667 |
| You want a detailed printable record | cnic.sims.pk portal |
| You suspect identity theft on your CNIC | 668 first, then franchise visit |
| You bought a used phone with mystery SIM | 667 with that SIM inserted |
| You need court-admissible documentation | Operator franchise visit with original CNIC |
For most users, both methods complement each other. Sara Khan recommends running 668 on your CNIC at the start of every month, and using 667 anytime an unfamiliar SIM enters your possession.
Operator-Specific BVS Codes
In addition to the universal 667 service, each network operator runs its own dedicated biometric verification (BVS) status code. These codes let you verify a specific SIM's BVS compliance directly with that operator's database:
- Jazz — Send your CNIC to 6001. Full Jazz guide.
- Telenor — Send your CNIC to 7751. Full Telenor guide.
- Zong — Send the letter V to 7911. Full Zong guide.
- Ufone — Send V to 7911 or dial *333#. Full Ufone guide.
- SCOM — Use regional helpline 1236 or SMS to 668. Full SCOM guide.
Unverified SIMs face deactivation in PTA enforcement sweeps. If any BVS check returns "pending" or "expired", visit the operator's franchise with your original CNIC for free re-verification — the process takes under 10 minutes and protects you from identity theft scenarios.
Limitations — What 667 Cannot Do
It is critical to understand what this method legally cannot return, regardless of any website promising otherwise:
- It cannot verify a SIM you do not physically have. The lookup requires the SIM to be active inside your phone. This is by design — PTA enforces this restriction to prevent remote identity violations.
- It cannot return the full unmasked CNIC. Only the last few digits are shown. The full CNIC is protected privacy data.
- It cannot return home address, family details, or location. No legal channel anywhere in Pakistan returns this information for someone else's SIM. Any website claiming to do so is illegal under PECA 2016, punishable by up to 3 years imprisonment and Rs. 5 million fine.
- It cannot work after MNP without prefix verification. If the SIM has been ported between networks, send the number to 76367 first to confirm the current carrier.
These limits are not flaws — they are deliberate identity theft protection features built into Pakistan's NADRA registry system. They exist to keep ordinary citizens safe from the kind of mass identity lookups that illegal SIM databases attempt.
Run a SIM Verification Today
If you have any unfamiliar SIM in your possession, insert it now and send MNP to 667. The reply is instant, the cost is negligible, and the information is official PTA data. For a broader audit of every SIM tied to your CNIC, use the CNIC Information Check tool instead. Together, these two methods cover every legal SIM verification scenario a Pakistani consumer will ever need in 2026.
