Zong (China Mobile Pakistan) is Pakistan’s second-largest network, known for strong 4G LTE coverage and competitive data packages — particularly popular among data-heavy users and in areas where Zong’s network infrastructure is strongest. Like all Pakistani networks, Zong operates a comprehensive USSD code system giving subscribers instant access to balance information, package subscriptions, and account management without requiring the My Zong app or customer service calls.
This guide provides every Zong USSD code organized by function — verified as of Jun 2026. USSD codes work without internet connectivity, work on basic feature phones, and give immediate responses. Knowing these codes makes Zong account management significantly faster.
For Zong SIM registration verification — confirming your Zong SIM is correctly registered on your CNIC, checking for unauthorized Zong SIMs, or verifying your SIM status beyond what USSD codes show — visit SimOwner.net.pk.
Zong USSD System Overview
Zong’s USSD system uses *310# as the main menu entry point — from which most services are accessible through submenu navigation. Direct codes exist for the most frequently used functions, bypassing the menu for instant results.
USSD code format: Dial like a phone number — enter the code and press the green call button. Response appears as a popup menu or instant text display.
Works without: Internet data, the My Zong app, or network signal (basic 2G/GSM signal is sufficient for USSD).

**21*[number]# | Activate unconditional call forwarding |
#21# | Deactivate all call forwarding |
*#21# | Check call forwarding status |
Critical security warning: Criminals impersonating Zong technical support sometimes instruct victims to dial call forwarding activation codes (directing their calls and OTPs to the criminal’s number). Never dial any code at a stranger’s instruction. If call forwarding is unexpectedly active on your account, dial #21# immediately to deactivate it, then call 310 to report the incident.
Check if Someone Is Using Your Zong Data
If your data depletes faster than expected:
- Dial
*102*5#— check remaining data vs your expected usage - Check active packages via
*310*2# - If a package you did not subscribe to is active — call 310 to report and cancel
Zong USSD and SIM Verification — What the Codes Miss
USSD codes provide account-level information for your own SIM. They do not reveal:
- Other SIMs registered on your CNIC — fraudulent Zong SIMs appear only via 668, not via USSD on your own SIM
- Your SIM’s registration history — when it was registered, at which location
- Whether biometric verification was properly completed at registration
For complete Zong SIM verification including unauthorized SIM detection and registration history:
- Send your CNIC to 668 (free, from any phone)
- Use SimOwner.net.pk’s SIM database tools for comprehensive guidance
- Access SimOwner.net.pk’s SIM info resource for verification interpretation
Zong Postpaid USSD Codes
Zong postpaid subscribers have additional code options:
| Code | Function |
|---|---|
*310*9# | Postpaid bill and usage information |
*310*9*1# | Current bill amount |
*310*9*2# | Usage breakdown |
*1000# | Postpaid account menu |
Zong USSD Troubleshooting
“Service Not Available” Response
- Check your Zong signal strength — USSD requires at minimum 1 bar of signal
- Try moving to better coverage area
- Some services are temporarily unavailable during network maintenance (typically 2am–4am)
Code Works but Gives Unexpected Menu
Zong’s USSD menus are periodically updated — menu structure may differ from documentation. Navigate the interactive menu to find the function you need, or call 310 for assisted service.
No Response After Dialing
- Confirm you pressed the call/send button after the code
- Ensure the code includes the
*at the start and#at the end - Some Zong codes require your SIM to have balance — check
*102#first

Frequently Asked Questions
Q: Do Zong USSD codes work on Zong MiFi (WiFi router) SIMs?
A: Some codes work on MiFi SIMs via SMS rather than USSD — MiFi devices do not have a keypad for USSD dialing. Send the equivalent service request via SMS to Zong’s service number, or manage via the My Zong app or web portal.
Q: My *102# shows a negative balance. What does this mean?
A: A negative balance on Zong typically means you have used the Zong Advance (airtime loan — *9090#) and the loan has been deducted from your credit. The negative amount is what you owe, which will be deducted from your next recharge.
Q: Can Zong USSD codes be used to check if my SIM is properly registered?
A: *6464# shows your SIM’s status in Zong’s system — if your SIM is active and registered, it will return account information. However, this only confirms your SIM is registered. To check for unauthorized Zong SIMs on your CNIC, send your CNIC to 668.
Q: Is there a Zong code to block my SIM remotely?
A: No — SIM blocking requires calling Zong customer service at 310 or visiting a Zong CSC. This is a security measure — if a code could block your SIM, criminals could use it against you. Blocking always requires verified agent interaction.
Q: Zong codes worked yesterday but none are working today. What happened?
A: Your SIM may have been suspended (for non-payment if postpaid, or potentially as part of a fraud action). Call 310 immediately to check your SIM status. If you suspect unauthorized SIM suspension, report it as possible fraud.
