PTA DIRBS Explained: Here’s How You Can Avoid Getting Your Phone and IMEI Blocked in Pakistan

As you might have heard, Pakistan Telecommunication Authority has launched DIRBS — Device Identification, Registration and Blocking System — that will block all smuggled and unregistered smartphones as well as feature phones in the country.

Before we help you understand how DIRBS works, and how can you register your phone to avoid any blocking, here are a few terms that you need to know well.


IMEI, or International Mobile Equipment Identity, is a unique number issued to every mobile phone in use today. It is also important to note that phones with dual SIM will have two IMEI.

This unique number (or numbers in case of dual SIM phones) is set at the time of its manufacturing. And because of its uniqueness, no two phones in the world can have similar IMEIs.

Now that you know what an IMEI is, it is time to dig in deeper and understand how DIRBS will make use of IMEI numbers to block unregistered and smuggled phones.


There will be basically three types of IMEI in DIRBS:

  • Invalid IMEI
  • Valid IMEI
  • Compliant IMEI / PTA Approved IMEI
Invalid IMEI

As mentioned above, two phones can never have similar IMEIs. The list of IMEIs that a manufacturer can use in their phones is issued by GSMA, a global authority that represents mobile operators from around the world.

In short, any phone in the world can be identified if it has valid IMEI or not by simply checking its IMEI number against GSMA’s list of approved IMEIs.

If a phone has a GSMA issued IMEI number, then it has a valid IMEI. If not, it has an invalid IMEI number.

For your information, some small, home-based Chinese manufacturers use dummy numbers as their phone IMEIs. At times they use all zeros as the IMEI or even alpha numeric numbers for their phones’ IMEIs. All of these numbers are considered as invalid IMEI. And the reason why some Chinese phone makers do this is because they want to avoid a nominal fee that’s charged by GSMA for issuance of IMEI list.

Another way that your phone can have an invalid IMEI is if you get your phone from a local market. Chances are that your IMEI number is flashed (software is re-installed) and re-coded with an invalid IMEI.

PTA Approved IMEI or Compliant IMEI

All phones that are imported through legal channels in Pakistan will have PTA approved IMEI numbers. For example, suppose Samsung is importing 10,000 phones into Pakistan per month, they will need to share the list of IMEI numbers of all the phones with PTA first.

These phones contain valid IMEIs (since they are GSMA approved). And once they are registered with PTA, the IMEI numbers of those phones will be considered as PTA approved IMEI number.

Alternatively, any IMEI number that is Valid and PTA approved is considered as Compliant IMEI. This term is used for DIRBS as well.

Valid IMEI

Third type of IMEI will be Valid; not compliant. Its those phones that come with GSMA approved IMEIs but are not registered with PTA, such as a phone that your cousin brought from Dubai may have valid IMEI but not compliant IMEI.

How to Check IMEI number of a Phone?

Now for the main thing. Checking your phone’s IMEI number is very simple. To do this:

  • Just dual *#06# from your dial pad.
  • You will get a pop-up that displays all the IMEI numbers of the phone (depending on whether you have a single SIM or dual SIM phone).

Here’s how the IMEI numbers usually look:

How to Check if an IMEI is Valid, Invalid, Compliant or Not?

You may have bought your phone from OLX, or an online store. Or maybe your cousin brought it for you from Dubai. In any case, there are a couple of reasons why you may need to check whether your phone’s IMEI(s) is Valid, PTA Approved or not.

Here’s how you can check if your phone comes with a Valid IMEI number or not. Furthermore, you can also check if it has a PTA approved (compliant) IMEI number or not.

  • Through Web:
    • Go to this website:
    • Enter your 15 Digit IMEI number
    • Press ‘Check’
    • You will be shown the status of the IMEI number on the next screen
  • Through SMS
    • Write a new SMS message
    • Type your 15 digit IMEI
    • Send it to 8484
  • Through Android application
    • Download this Android app from here
    • Install the DIRBS app on your smartphone
    • Open app and enter your 15 digit IMEI number and that’s it

Possible Outcomes of IMEI Checks

While checking the IMEI number of your phone through the above three methods, there could be three possible outcomes for your phone:

  • Valid IMEI: This means that your phone IMEI is GSMA approved but not PTA approved.
  • Invalid IMEI: Not a GSMA approved IMEI, nor PTA approved.
  • Compliant IMEI: It is both GSMA approved and PTA approved IMEI number.

Who Needs to Register their IMEI Number to Avoid Blocking

Now that we have an idea about IMEI numbers and how to check if its valid or not, or compliant or not, you need to proceed to the next step.

Depending on your scenario, here’s what you need to do to register your smartphone so that it doesn’t get blocked from normal use later on.

Invalid IMEI Numbers

Below are the possible scenarios if your IMEI number is Invalid:

  • Your phone is manufactured by a low-end Chinese company that didn’t use a GSMA approved IMEI number
  • You flashed your phone (re-installed the software) and now your new IMEI is not GSMA approved

Those with Invalid IMEI numbers, will get an SMS from the DIRBS system directing them to pair their smartphone with SIMs that they want to use on this phone. After a certain deadline (that will be mentioned in SMS from DIRBS), this phone won’t accept any new SIM.

So for example if your smartphone has an Invalid IMEI number, you must use all the SIMs that you want to use with this smartphone till the end of deadline. After the deadline, you won’t be able to use a non-paired SIM on this phone.

Using a SIM means, making at least one revenue generating activity, i.e. make a call, send an SMS or use mobile internet.

Once paired with a SIM, phones with Invalid IMEI numbers can be used with only these SIMs till the end of life of the phone.

And if you haven’t paired the phone (with Invalid IMEI) before the deadline, you won’t be able to use this phone ever again in life in Pakistan.

Valid IMEI (but Not Compliant)

There are some phones which could have a Valid IMEI but not Compliant IMEI numbers. This usually happens if:

  • You bought a phone from Dubai and took it back with you in Pakistan,
  • You ordered a phone from Ali Express that was delivered to you through a courier company,
  • You bought the phone from an online store that imported the device from abroad,
  • Your cousin brought you a new Smartphone from US,
  • You are using a test device issued by phone companies.

Phones with Valid IMEIs but not Compliant IMEIs must use the phone at once — with any SIM — before the deadline (that will be communicated to you in the SMS sent by DIRBS/PTA).

If you use this phone before the deadline, then you will never be asked to register the phone. In fact, you can use other SIMs on these phones without the need to pair them.

If these phones are used before deadline, you will be allowed to use them as normal for the remainder of their life, just like you do it now.

If a phone (with valid but not complaint IMEI) was never used even once after the deadline then you will be given around 20 days to register the IMEI numbers with PTA, i.e. by going to PTA’s website and getting an NOC from there.

This is the same NOC that is currently required if you order a phone from Ali Express or from anywhere else.

Not to mention, after the deadline, a custom fee might be required in order to get an NOC from PTA to register the IMEI number.

Also remember that all those phones with Valid (but not compliant) IMEI numbers will not be allowed to register with Pakistani mobile networks if deadline expires and if NOC is not obtained.

Compliant IMEI

Those phones with compliant IMEI — that is with Valid and PTA approved IMEIs — need to do nothing. They can continue using their smartphones as they were using before and there is not going to be any restriction on them whatsoever.

Never Forget to Check IMEI When Buying a Phone

With DIRBS in place, as you may have imagined, any phones with invalid IMEIs or non PTA approved IMEIs are going to be in trouble.

You should always make it a point to check the IMEI number of the phones while making new purchases. Whether you’re getting it from a friend or from an online store or even when you buy a phone from a shop, don’t forget to check its IMEI number.

Benefits of DIRBS

You must be wondering that this new system brings a lot of hassles and limitations to owning a mobile phone in Pakistan. However, if implemented correctly, DIRBS brings a host of benefits for every mobile user in Pakistan. Here are some of them:

  • Phone snatchers won’t be able to sell your phone, since you can easily get them blocked via your registered IMEI number.
  • Unscrupulous sellers who sell you a refurbished phone for the price of a new one will not be able to do so again.
  • With this system in place, you are going to get 100% legal devices, that naturally come with better quality, after sales services and warranties.

    • Arslan Ejaz

      No you are not registered with PTA and also not blacklisted IMEI that’s why you have to put any sim during the deadline at least once and make a call or sms and it will auto verify.

      • Tayyab Zaffar

        mean i don’t need any PTA reregistration right or if i bought another device under the deadline and use with my sim (i don’t need to be registers with PTA NOC….. right ) its auto registered right

  • Khaliq Mehmood

    good article.i think if your phone’s IMEI is valid but not compliant then you have to use this phone once before 29-06-18 (Deadline).the phones with valid IMEI will be automatically registered in PTA and you dont need to get it registered (Just insert sim and make call or sms before deadline).this is what i understand after checking my phones IMEI on DIRBS.correct me if i m wrong.

    • aamir7

      You are right. Any new phones with valid IMEIs but not approved by PTA will need NOC after the deadline.

    • aamir7

  • Kamra

    According to the DIRBS law document published in official gazette of pakistan, when PTA gives type approval to a certain phone model, it will be whitelisted and all units of the same model must be usable afterwards without any registration.

    • Tayyab Zaffar

      link plz

  • Adnan

    Question: What happens if i am living abroad and i visit Pakistan(after the deadline) and i want to use my cell here with a local sim?

    • Tayyab Zaffar

      gae kam say you have to registered under PTA

    • Syed Sheharyar Ali

      Through DIRBS Device Registration System, you must register the device by the time you arrive Pakistan. A person is allowed to register up to 5 devices every 12 months for personal use. Usually CoC is issued within 24 hours of application.

  • Safiullah Jan

    “Device IMEI is Valid. Insert SIM and make a call/SMS to anyone on or before 29/06/18 date for auto registration”
    It is shows me above msg i,e Means i m clear??

    • Tayyab Zaffar

      just a warning message and your phone not block and aromatically registers by PTA after the dead line

  • Adnan

    8484 SMS Charges Please ?

  • Amir Bro, how can we report a snatched phone? What is the process to get it blocked? We have police report.

  • Syed Sheharyar Ali

    You can register 5 devices for personal use per year without having to pay any taxes.

  • Amir Butt

    Thank you for the clarification. I need to understand what mistake did the people who live in the villages made? People got phones by saving lots of money and after this system they won’t be able to use the phones with any other sims. They cannot even shuffle their phones. Huge loss I don’t see this system will be welcomed by most of the people. Let’s hope for the best.

  • Very confusing!!!

  • Idrees

    Device IMEI (35274509093**10) is Valid. Insert SIM and make a call/SMS to anyone on or before 29/06/18 date for auto registration

    Device IMEI (35274509093**02) is Valid. Insert SIM and make a call/SMS to anyone on or before 29/06/18 date for auto registration

    Status is same for both IMEI althoug i am sending daily 1000’s of message and again sent message but status is same. what should i do ?

    • Mohsin

      You don’t need to do anything.. just use any Pakistan Network SIM in your phone and make chargeable activity(Make call, SMS, or User internet) before 29 June 2018 to get auto registerd.

      • Idrees

        i have done with this but still status i same what to do

        • Tayyab Zaffar

          ck after dead line bro

  • mustafa

    @Aamir 7

    “If you use this phone before the deadline, then you will never be asked to register the phone. In fact, you can use other SIMs on these phones without the need to pair them”

    Situation: I buy a. Phone valid;not compliant, use a Sim or Sims of mine for use, later sell the phone to someone.From your post snippet above, the new user can put his sim or sims, and can use it.

    If this is true, a stolen phone can be used , unless there is a way for me to report stolen.

    If my understanding is not correct, then I buy a valid/not compliant phone, and use it for myself, and then I cannot sell it.

    Please clarify

  • Abrar Ali Khan

    Apparently if you have a Valid but not Confirmed mobile phone (i.e. non duty paid phone from dubai) then all sim cards you use in those phones will have their phone numbers locked against the imei’s. After June 29th 2018 no other numbers can be used against the imei’s. ProPakistani team please confirm above.

    Phone shops have started putting in sim cards and making calls from their smuggled stock so that they can sell it after the deadline but if the above is true then this tactic will not work.

    • tazzix

      This can only work with stock already in the country, but would for sure discourage future smuggling. Now allowing 5 devices in 12 months is a bit too much for genuine usage and ‘importers’ would use CNIC numbers of village people to get devices registered. I think 2-3 devices would be better.

  • Azhar

    My Question: I am here in Dubai and using a phone purchased here in UAE and it has a valid IMEI number. I don’t have any plan to come to Pakistan before August 2018. So if I come to Pak after the PTA deadline i.e 29/06/18, will my cell phone work? And if not, what will be the procedure to make it work as right now I cant use any Pakistani sim card to make at-least a single call to sms.

    • aamir7

      You will be allowed to use the phone for 20 days then you will get a message from dirbs to register through drs

  • Eli Ehsan

    what a palpable system that’s gonna be from PTA…. Oh wait… aren’t all the systems from PTA the same…. Who the h3ll puts “Valid but not compliant” category in a system like DIRBS? (terrible acronym I must say), matlab banda har saal bahar se device mangaye or NOC leta phire… allow FACETIME on iDevices in Pakistan that are made for pakistan phr ye ahmaqana system launch kijiye… shukria

  • xkz

    Device IMEI is Valid. Insert SIM and make a call/SMS to anyone on or before 29/06/18 date for auto registration.
    M using my phone since last 2 years . Still m getting the above mentioned message.. :(
    What should i do ???

  • DevilMind

    when i register on website, it says CNIC Already registered.
    but when i try to Logon, it says No Email Record.
    Forgot password only shows Email reset, but no CNIC reset.
    Now how can i link my CNIC to my Email for login error?

  • Ahsan

    After the phone is auto registered how will they make sure that the person calling for blocking of the phone is the right owner? Will they automatically link the phone to SIM’s CNIC or what?

  • MIS

    Please guide, How can I block my stolen phone IMEI?
