Call Barring Codes: Full List, Password, and How to Reset It (2026)
NoDial Editorial ／ 2026-09-29You want the dial code to turn call barring on or off, or your phone asked for a "barring password" you have never heard of. This page lists every standard call barring code with what it blocks, shows how to use the codes on Android, and explains the call barring password: the defaults carriers publish, how to change it, and how to get it reset if it is forgotten or locked.
Current as of September 2026. The codes below come from the 3GPP standard that GSM and LTE networks follow, but your carrier decides whether it accepts them and sets its own password. Check your carrier's help page before relying on them.
1. The short answer
The main call barring codes are *33*PW# to bar all outgoing calls, *331*PW# to bar outgoing international calls, *35*PW# to bar all incoming calls, and #330*PW# to turn every kind of barring off. Replace PW with your 4-digit call barring password. To check whether outgoing barring is on, dial *#33#. To change the password, dial **03*330*OLD*NEW*NEW#.
The password is set by your carrier, not by the phone, and there is no universal default. Published defaults include 0000 or 1234 (Vodafone Australia) and 1919 (Vodafone UK's device guides). If the default is refused, ask your carrier to reset it rather than guessing.
* turns barring on, # turns it off, *# checks it. The number in the middle picks what is barred. PW is a password held by your carrier, not your SIM PIN.
2. Full list of call barring codes
These service codes are defined in 3GPP TS 22.030 (Annex B). Every one of them needs the barring password to turn on or off.
| What is barred | Turn on | Turn off | Check |
|---|---|---|---|
| All outgoing calls | *33*PW# | #33*PW# | *#33# |
| Outgoing international calls | *331*PW# | #331*PW# | *#331# |
| Outgoing international calls except to your home country | *332*PW# | #332*PW# | *#332# |
| All incoming calls | *35*PW# | #35*PW# | *#35# |
| Incoming calls while roaming abroad | *351*PW# | #351*PW# | *#351# |
| All barring (every kind above) | – | #330*PW# | – |
| All outgoing barring | – | #333*PW# | – |
| All incoming barring | – | #353*PW# | – |
| Change the barring password | **03*330*OLD*NEW*NEW# | ||
* 330, 333 and 353 are group codes, most useful for switching everything off at once. The standard defines them for other operations too, but "turn off all barring" is what most people need.
What each category means in practice, and when to use which: Call Barring on Android. For the international options specifically: How to Block International Calls on Android.
How the codes are built
Every code follows the same pattern from the standard: *SC*PW# to activate, #SC*PW# to deactivate and *#SC# to check, where SC is the service code from the table. You can add a third part to limit the bar to one kind of service, such as 11 for voice calls: *33*PW*11# bars outgoing voice calls only. Vodafone Australia lists codes in this form, for example *331*PIN*11#. Without that part, the bar applies to all services, which is what most people want.
3. How to use the codes on Android
- Open the Phone app and go to the keypad.
- Type the code exactly, including every * and #, with your password in place of PW. On a dual-SIM phone, choose the SIM you want to change.
- Press the call button. The network answers with a message saying the service was activated, deactivated, or what its status is.
You can also use the Call barring screen instead of codes, if your carrier shows it:
- Samsung Galaxy: Phone app > three-dot menu > Settings > Supplementary services > Call barring. Samsung's own support page gives this path.
- Phones using Google's Phone app (Pixel and others): Phone app > three-dot menu > Settings > Calling accounts > your SIM > Call barring. Carrier device guides show this path.
Android lets each carrier decide whether the Call barring screen appears at all: in Android's carrier settings it is off unless the carrier turns it on. If you cannot find it, the codes are the way in. In our own test on a Pixel 8a (September 2026), the Call barring entry only appeared while mobile data was on for that SIM.
4. The call barring password
Because the carrier's network does the blocking, the network also checks the password. According to the 3GPP standards:
- The password "will consist of four digits in the range 0000 to 9999."
- There is one password per subscriber "for all barring services": the same one for outgoing, international and incoming barring.
- The carrier "has to register a password at provision time", so the starting value depends on the carrier.
- The password "may not be Erased or Interrogated": no code or menu shows you the current password.
| Code the phone asks for | What it protects | Where it lives |
|---|---|---|
| Call barring password | Turning call barring on or off | Your carrier's network |
| SIM PIN | Using the SIM card when the phone starts | The SIM card |
| PIN2 | SIM features such as Fixed Dialing Numbers | The SIM card |
| Screen lock | Unlocking the phone | The phone |
5. Default passwords carriers publish
Values we found on carriers' own pages in September 2026. Many carriers publish none.
| Carrier | Published default | Where it says so |
|---|---|---|
| Vodafone (Australia) | 0000 or 1234 | Call barring support page: "If you haven't changed it, the default barring PIN should be '0000' or '1234'." |
| Vodafone (UK) | 1919 | Device guide for the Samsung Galaxy A03s: "The default barring password is 1919." |
| Vi (India) | Usually 0000 | Vi blog: "the default is usually 0000" |
| Airtel (India) | Not published | Says to contact the carrier if you forget the password |
| Telstra, EE, O2 | Not published | Device guides only say to key in your barring password |
Two Vodafone companies publish different values, so the brand alone does not tell you the default. Lists of "default passwords by carrier" on other sites are usually copied without a source; treat them as guesses.
6. How to change the password
Dial **03*330*OLD*NEW*NEW# and press call: OLD is the current password, NEW is the new four-digit password, typed twice. The standard also defines the single-star form *03*330*OLD*NEW*NEW#. If the change is refused, for example because OLD was wrong, "the old password remains unchanged".
Some phones also offer a password change on the Call barring screen, if the carrier allows it (Android has a separate carrier setting for this). If yours does not, the code works regardless of the menu.
7. How to reset it: wrong, forgotten or locked
Forgotten: no code reveals the password, so only the carrier can reset it. Vodafone Australia: "If you've forgotten your barring PIN, give us a call." Airtel says you "may not be able to manage your call barring settings until you contact your mobile service provider."
Locked: the standard says that if the subscriber "enters incorrect password more than three consecutive times, all control procedures related to the use of the password are made impossible until the service provider instructs the network to again accept password-related requests". If every password is suddenly refused, stop trying and ask the carrier to unlock and reset it.
Barring is on and you cannot turn it off: the carrier can remove it. Samsung's support page on calls that will not connect says the same: if call barring is activated, contact your SIM provider to deactivate it.
When you contact the carrier, say "call barring password" or "network password for call barring", so that the support agent does not start the SIM PIN or PUK process instead.
8. When a code does not work
- "Connection problem or invalid MMI code". The network did not accept the code. Check every * and #. If it still fails, the carrier may not let subscribers control barring on your SIM, which the standard allows: a carrier "needs not to offer this option to its subscribers". A wrong password is only one possible cause.
- The carrier manages the barring. The standard also allows barring to be controlled "by the service provider", in which case password requests from the phone are refused. Only the carrier can change it.
- No Call barring screen. The carrier has not enabled it on your phone, or mobile data is off for that SIM. Use the codes.
- Two SIMs. Each SIM has its own barring and its own password. Make sure the right SIM is selected before you dial.
9. Blocking one number without any code
Call barring works by category: it can bar all outgoing calls or all international calls, but not calls to one specific number. If that is what you actually want, no code or password is needed.
- One number ✓
- No code, no password
- Any carrier (Android)
Android lets one app check each outgoing call as you place it and end the ones you asked it to end. NoDial uses this to block calls to the numbers you choose, on your phone, before the call leaves. Other calls go through as usual, and your contacts are not changed.
- Install NoDial and let it handle call redirection when Android asks (a one-time prompt).
- Add the number you have decided not to call.
- Choose how it is blocked: always, on certain days and hours, or up to a set number of calls per day, week or month.
The first number is free. Turning a number's block off takes effect one hour later, and you can cancel during that hour. To block every outgoing call except a few numbers, without codes or a carrier, see How to Block All Outgoing Calls on Android.
* NoDial works on your phone, not on the carrier's network, so it does not change your carrier's call barring or its password. Emergency calls are never blocked.
10. FAQ
- What is the code for call barring?
- *33*PW# bars all outgoing calls, *331*PW# bars outgoing international calls and *35*PW# bars all incoming calls, where PW is your 4-digit barring password. #330*PW# turns every kind of barring off, and *#33# checks whether outgoing barring is on.
- How do I cancel all call barring?
- Dial #330*PW# and press call, where PW is your barring password. If the password is refused, ask your carrier to remove the barring and reset the password.
- What is the default call barring password?
- It depends on the carrier; the standard only says it is four digits. Published defaults include 0000 or 1234 (Vodafone Australia), 1919 (Vodafone UK device guides) and usually 0000 (Vi, India). Many carriers publish none.
- How do I reset my call barring password?
- If you know the current one, change it with **03*330*OLD*NEW*NEW#. If you forgot it or it is locked, only your carrier can reset it; no code shows the current password.
- What does *#33# do?
- It asks the network whether barring of all outgoing calls is currently on. It does not show or need the password.
- Why does it say "invalid MMI code"?
- The network did not accept the code. Check the exact characters first. If it still fails, your carrier may not let subscribers control call barring on your SIM, or the password may be wrong. Your carrier can tell you which.
11. Summary
*33*PW# bars outgoing calls, *331*PW# international calls, *35*PW# incoming calls, and #330*PW# turns everything off. PW is a four-digit password set by your carrier; change it with **03*330*OLD*NEW*NEW#, and ask the carrier to reset it if it is forgotten or locked.
- * on, # off, *# check. The middle number picks the category.
- One password for all barring. Not your SIM PIN, PIN2 or screen lock.
- No universal default. Published examples: 0000 or 1234, 1919, usually 0000.
- More than three wrong tries in a row can lock password changes until the carrier unlocks them.
- To block calls to one number, NoDial (Android) needs no code or password. First number free.
