Switching between Saudi operators, or advising a friend who just moved from STC or Mobily to Zain? Good news: call barring codes are identical across all three, so nothing about how you manage restrictions changes when you change carriers — only the customer care number for a PIN reset does.
Quick answer
Standard GSM barring codes with your PIN (default 0000):
| Bar | Code |
|---|---|
| All outgoing calls | *33*PIN# |
| Outgoing international | *331*PIN# |
| All incoming calls | *35*PIN# |
| Remove all bars | #330*PIN# |
One code set, three Saudi operators
Because barring is a GSM network standard rather than a Zain-specific feature, the exact same codes work identically on Mobily and STC. If you’ve used call barring before on either of those, there’s nothing new to learn here — only 959 as the number to call for a PIN reset is Zain-specific.
Why this consistency is useful
Family members or a small business often run lines across more than one Saudi operator rather than all on one — knowing the codes are universal means you can set up identical barring rules across a mixed-operator household or team without needing operator-specific instructions for each line.
Managing via the app instead
The Zain KSA app offers the same barring controls through a tappable interface if you’d rather not dial codes at all.
Want to redirect calls instead of blocking them? Zain doesn’t currently have a dedicated forwarding guide on this site, but Zain KSA call waiting covers the related feature.

Frequently Asked Questions
Can I manage barring in the Zain app?
Yes. The Zain KSA app offers the same controls without dialling codes, handy if you'd rather tap than remember sequences.
What is the default barring PIN?
0000 unless you've set your own. Change it through 959 or the app so the bars can't be removed by anyone else.
How do I lift all bars?
Dial #330*PIN# to clear every bar at once, then confirm with *#33#.
Are the barring codes really the same on Mobily and STC?
Yes — call barring is a GSM standard, so *33*, *331*, *35*, and #330* behave identically across all three Saudi operators.
If I switch from STC to Zain, do I need to relearn barring?
No — the codes carry over exactly. Only the customer care number for a PIN reset changes (959 for Zain vs 900 for STC).
