Jazz and Zong Caller Name Service in Pakistan: Codes, Daily Charge and How to Hide Your Name

Jazz Caller Name shows an unknown caller's name in a flash message for Rs 3.20 a day including tax: dial *7773# to start and *7773*5# to stop. Zong Caller Name does the same for Rs 1.50 plus tax a day on *254#, stopped with *254*6#. To keep your own name out of these services, send U to 7773 on Jazz or dial *254*3# on Zong.

Unknown calls are a daily nuisance in Pakistan, from loan apps to scam "bank officers". Both big networks now sell a caller name service that works without internet or an app, even on a keypad phone. Both also draw names from a crowd-sourced database, which means your own name may be shown to people who call you or whom you call. We read the Jazz and Zong service pages on 20 October 2026.

Jazz and Zong both sell caller name for a daily fee

Jazz charges Rs 3.20 a day including tax. Zong charges Rs 1.50 plus tax a day. Both renew daily until you unsubscribe, and both show the name in a flash message on your screen when an unknown number rings.

Over a 30 day month, Jazz's service costs about Rs 96. Zong's costs about Rs 54 once 19.5% sales tax is added. Those are our sums from each network's listed price.

The names come from a crowd-sourced database, not NADRA

Neither network uses its own customer records. Jazz says the data "is not sourced from any Jazz database" and comes from a crowd-sourced database. Zong says the same about its customer database. Both say results are best effort and some names will not appear.

In plain words, the name you see is whatever other people saved for that number. It might be "Ali Plumber", a nickname, or a wrong name. Treat it as a hint, not proof. A caller showing a bank's name can still be a fraudster, and nothing on either page says the name is checked.

Both services also say they do not read your own contact list. Jazz states it does not take data from the user's address book, and Zong says the same.

How to hide your own name from caller name services

You do not have to subscribe to be in the database. Your name may show on other people's phones because someone else saved it. Each network gives a way to remove or change your listing in its service.

1. On Jazz, send U to 7773 to hide your name.
2. On Jazz, send N followed by your name to 7773 to change it.
3. On Zong, dial *254*3# to unlist your number.
4. On Zong, dial *254*1# to change your name, or *254*2# to list it again.
5. Repeat on any app based caller ID you use, since those keep separate lists.

Jazz's page lists the hide and change commands in its FAQ for the service, so they may only work from a subscribed Jazz number. Zong's page lists its codes among the service's features. Neither page says whether a non-subscriber can unlist. If the code fails, ask the network's helpline. App based caller ID is a separate system; the steps for removing your number from Truecaller cover the biggest one.

Five cases where no name appears

A blank screen does not mean the service failed. Both networks list the cases where nothing is shown.

• The caller's number is not in the database.
• The call comes from an international number, on Zong.
• You turned the flash message off, with *254*4# on Zong.
• On Zong, the call is a Yaari Call, the collect call service.
• On Jazz, you blocked flash messages from that number by sending CL:92 followed by the number to 7773.

Zong adds one clash. Users of its My Status or Dial Tune services cannot subscribe to Caller Name until they stop those. Jazz has no such rule on its page.

Charges continue even when your balance is zero

Jazz says a prepaid user with no balance keeps the service, and the pending charges are deducted once balance is added. So a forgotten subscription can eat the first rupees of your next recharge. Zong says its service renews automatically.

If you see Rs 3.20 vanish every day and never subscribed, dial *7050# on Jazz to see what was deducted in the last 3 days. PTA rules say a paid service needs your consent, so an unwanted subscription is worth a complaint. For calls you never want to hear again, a block on your phone or the network's call block service works better than knowing the name.
