By Quick answer: The Jazz number check code is *99#. Dial it from your Jazz SIM and your number appears on the screen within a few seconds. On a dual SIM phone, pick the Jazz SIM when the phone asks which SIM to use.
Most people need their own number at the worst moment: filling a form at a bank counter, giving it to a delivery rider, or registering on an app that sends an OTP. This page shows the official code, four backup methods for when the code does not respond, and what to do if the SIM itself is not working.

How to use the Jazz number check code
Jazz lists *99# as its "Check Jazz Number" code on its official self-service dial code page. It is a USSD code, so it works without internet.
- Open the phone (dialer) app, not the messages app.
- Type
*99#and press the call button. - If your phone has two SIMs, choose the Jazz SIM. Choosing the other SIM sends the code to the wrong network and you get an error or nothing.
- Read your number in the pop-up on screen. Some phones also receive it as an SMS a few seconds later.
Write the number down or save it as a contact named "My Jazz" so you do not have to dial the code again.
Other ways to check your Jazz SIM number
If *99# does not respond, one of these will still get you the number.
1. Check your phone's settings
Many phones read the number from the SIM and show it in settings. On an iPhone, open Settings > Phone > My Number (on newer iOS versions the number is under Settings > Apps > Phone). On Android, look under Settings > About phone > Status or SIM status; the exact path depends on the brand. If the field is blank or shows "Unknown", the number was never written to the SIM, so use another method.
2. Use the SIMOSA app
Jazz's self-care app, SIMOSA (formerly called Jazz World), logs you in with your Jazz number and shows your account details on the home screen. If the app is already installed and signed in, your number is there.
3. Call or message someone you trust
Call a family member or friend and ask them to read the number that appears on their screen. It costs a normal call, but it works even when USSD codes fail.
4. Look at the SIM card holder
The plastic card your SIM came in usually has the number printed on it, along with the PUK code. If you kept it, the number is there.
Why *99# sometimes does not work
| What you see | Likely reason | What to do |
|---|---|---|
| "Connection problem or invalid MMI code" | The code went through the other SIM, or there is no signal | Select the Jazz SIM and try again where you have signal |
| Nothing happens | Phone is in airplane mode or the SIM is not detected | Turn airplane mode off, restart, reinsert the SIM |
| "SIM not provisioned" or no network at all | The SIM may be inactive after long non-use | Dial *8822# to restore an expired number (Jazz FAQ), or see the Jazz SIM Lagao offer |
| SIM was lost and you are using a new one | A replacement SIM keeps your old number | Dial *99# on the new SIM; the number is the same |
Check how many SIMs are on your CNIC
Sometimes the real question is not "what is my number" but "which numbers are registered in my name". PTA runs a SIM information service for this: send your 13 digit CNIC number, without dashes, by SMS to 668. The reply lists how many SIMs of each network are registered on your CNIC. It shows counts, not the full numbers, so use it to spot a SIM you do not recognise and then visit a Jazz franchise to block it.
Jazz number formats explained
Jazz numbers start with 0300 to 0309 or 0320 to 0329 (the 032 range belonged to Warid before it merged into Jazz). When an app or a foreign service asks for an international number, drop the first zero and add +92: 0301 1234567 becomes +92 301 1234567. Numbers that moved to Jazz from another network through porting can start with a different prefix, so the prefix alone does not prove the network.

Frequently asked questions
What is the Jazz number check code?
The Jazz number check code is *99#. Dial it from the Jazz SIM and your number shows on the screen. Jazz lists it on its official self-service dial code page.
Does *99# work without balance?
Jazz's dial code page does not list a charge for *99#. If it does not respond on a SIM with zero balance, check the number in your phone's settings or call a friend instead.
How do I check my Jazz number on a dual SIM phone?
Dial *99# and choose the Jazz SIM when the phone asks which SIM to use. If it never asks, set the default calling SIM to Jazz in settings, dial again, then switch the default back.
Can I find out who owns a Jazz number?
No official public service shows another person's name from their number. Sites that claim to do this are not run by Jazz or PTA. You can only check the SIMs registered on your own CNIC by sending your CNIC number to 668.
Is my number the same after a SIM replacement?
Yes. A replacement SIM from a Jazz franchise keeps the same number. Dial *99# on the new SIM to confirm.
