USSD Codes and SIM Owner Details: Why *99#, *310#, *345#, and *333# Don’t Work

The claim going around

A handful of “SIM owner details” websites tell readers to dial specific USSD codes to instantly find out who owns any phone number. It is a tidy story, and it spreads fast, but it does not hold up once you actually test it.

We picked the exact codes these sites mention most often, one for each major operator, and dialed every single one. Not one of them returned a name, a CNIC, or any identity information, for our own number or anyone else’s.

Below, we walk through each code individually, so you can see precisely what happens the moment you dial it.

What a USSD code actually is

USSD stands for Unstructured Supplementary Service Data. In plain terms, it is a short, real-time menu system your operator built for quick account tasks, things like checking your balance, buying a bundle, or managing a service, all without needing internet.

Every operator in Pakistan runs its own set of USSD codes: Jazz, Zong, Telenor, Ufone, SCOM, and ONIC. Each code is scoped to a specific function that the operator programmed, and that function never includes handing over a third party’s registration details. USSD menus are built for self-service, not for identity lookups.

Jazz *99# — tested and explained

Dial *99# on a Jazz SIM, and the screen shows exactly one thing: your own 11-digit phone number. That is the entire function of this code.

It exists purely as a quick way to check your own number when you have forgotten it, for example after switching SIMs. It has no connection whatsoever to CNIC data, ownership records, or anyone else’s information.

Zong *310# — tested and explained

Zong’s *310# opens an account information menu. From there, you can view your balance, your active packages, and current offers available on your line.

Nowhere in that menu does an option appear for checking ownership, CNIC details, or any other subscriber’s data. It is strictly an account self-service tool, the same category as a balance-check code.

Telenor *345# — tested and explained

Dialing *345# on Telenor opens the operator’s general services menu. Inside, you will find balance information, package options, and other standard account features.

Just like the Zong code above, this menu has no branch that reveals who owns a SIM. It manages your own account, and nothing beyond that.

Ufone *333# — tested and explained

Ufone’s *333# code opens the SIM services menu, covering balance checks, package subscriptions, and account settings.

Once again, ownership lookup is simply not a feature this menu offers, on Ufone or on any other network. Every operator built these codes around the same purpose: helping you manage your own line quickly.

What about SCOM and ONIC

SCOM, which serves Azad Jammu and Kashmir and Gilgit-Baltistan, runs its own account menu through a dedicated USSD code as well, again limited to balance and package information. ONIC, the digital-first brand operating on Ufone’s network, leans mainly on its own app for account management rather than a single fixed USSD code.

The pattern holds across every operator in the country. USSD exists to serve the account holder, not to expose anyone’s identity to someone else.

Why no USSD code can reveal ownership

USSD sits entirely within an operator’s own billing and account system. It was never designed to talk to PTA’s national subscriber registry, which is the actual database that links a SIM to a CNIC.

Consequently, no operator USSD menu has the technical ability to pull CNIC or ownership data, even if a site claims otherwise. The two systems are built separately, on purpose, precisely to keep subscriber identity data protected.

The only official way to check SIM details

If you actually want to know how many SIMs sit under your own CNIC, PTA gives you two genuine, free options.

Both draw from the same PTA registry, and both only ever return your own record. Neither one, and no USSD code either, will show you who owns someone else’s number.
