How to Check SIM Registration Date in Pakistan — All Networks Official Methods (2026)

Want to know when your SIM was registered in Pakistan? There is an important difference between checking the SIMs registered on your CNIC and checking the exact registration or activation date of a particular mobile number.

PTA’s official SIM Information System lets you check the total number of SIMs registered against your CNIC. You can also check this through the 668 SMS service. However, the public PTA system does not provide an exact registration date for each SIM.

If you need the date for a specific number, the correct next step is to contact the network that issued the SIM and ask whether its subscriber records contain the original registration or activation date.

Quick Answer

What you want to know	Best official method	Exact date shown?
How many SIMs are on your CNIC	PTA SIM Information System	No
SIMs registered against your CNIC by SMS	668	No
Network of a mobile number	PTA SIM Information System	No registration date
Exact registration date of your own number	Relevant network	Depends on operator records
Activation history	Relevant network	Depends on available records
Unknown SIM on your CNIC	PTA + network operator	Investigate through official channels

The important point

668 is a SIM ownership/count check, not an exact SIM registration-date checker.

That distinction matters because many websites describe 668 as if it can show the complete history of a SIM. PTA’s own material describes the service as a way to check the number of SIMs issued against your CNIC.

How to Check SIMs Registered on Your CNIC

Before looking for the date, first Check SIM Owner Details by CNIC

Method 1: Check through PTA’s online SIM Information System

Open the official PTA SIM Information System:

PTA SIM Information System

Enter your CNIC number and complete the verification. The system is designed to show the total number of SIMs registered against your CNIC.

Method 2: Send your CNIC to 668

You can also check through SMS:

Open your phone’s Messages app.
Enter your 13-digit CNIC number without dashes.
Send it to 668.
Check the response.

PTA’s guidance also recommends periodically checking the SIMs issued in your name and taking action if you find an unauthorized connection.

Can PTA 668 Show the Exact SIM Registration Date?

No.

The public PTA SIM Information System tells you how many SIMs are registered against your CNIC. It is not a public database where you enter a number and receive its exact original registration date.

So if you are searching for:

SIM registration date
SIM activation date
Original SIM issue date
Date a mobile number was registered

you may need to go beyond the PTA count check and contact the relevant operator.

How to Find the Exact Registration Date of Your SIM

Once you know the network, contact that operator and ask for the original registration or activation date of your mobile number.

Use the wording:

“I want to know the original registration or activation date of my mobile number. Please check the date available in your subscriber record.”

This is better than simply asking for the “SIM date,” because a number may have had a SIM replacement later.

Jazz SIM Registration Date

For a Jazz number, you can contact Jazz customer support through SIMOSA or its customer-care numbers.

111 for existing prepaid customers
0 111 300 300 when calling from another network
SIMOSA for customer queries and complaints

Jazz also provides a franchise locator for customers who need in-person assistance.

Jazz official customer support

Ask whether the original registration or activation date of your number is available in the subscriber record.

Zong SIM Registration Date

Zong customers can contact the operator through:

310 from a Zong number
(051) 111-222-111 from other numbers
Zong service centers or franchises

Zong’s official contact page confirms these customer-support channels.

Zong official customer support

When contacting Zong, ask specifically for the original registration or activation date, rather than only asking whether the number is registered in your name.

Ufone SIM Registration Date

Ufone customers can contact:

333 from Ufone
033-11-333-100 from other numbers

Its also provides sales and service centers for customers who need in-person help.

Ufone official customer support

Ask the representative whether the original registration or activation date is available for your number.

Telenor SIM Registration Date

Telenor’s official self-service information lists 345 as the helpline for individual prepaid and postpaid customers. It also lists 042 111 345 100 as a UAN option in its customer information.

Telenor official website

For the exact date, ask Telenor to check the original registration or activation record for your number.

Registration Date vs Activation Date: What’s the Difference?

This is one of the most important things to understand when checking an old SIM.

Suppose you have been using the same mobile number since 2018 but replaced the physical SIM in 2025 because it was damaged.

The SIM replacement date could be 2025 even though the number was originally registered much earlier.

So an operator’s record may contain different dates related to the same connection, such as:

Date type	What it can mean
Original registration date	When the connection was initially registered
Activation date	When the service became active
SIM replacement date	When a replacement SIM was issued
Ownership transfer date	When the subscriber details changed
Reactivation date	When a previously inactive connection was restored

If you need the first-ever date, clearly ask for the original registration/activation date, not the latest SIM replacement date.

What If You Recently Replaced Your SIM?

A SIM replacement does not necessarily mean you received a new mobile number.

Your number can remain the same while the physical SIM card changes.

That is why checking a date without asking what the date represents can give you the wrong impression.

For example:

Original number registration: 2019
SIM replacement: 2025

If an operator gives you the 2025 date without context, you might assume the number was newly registered in 2025. It may simply be the date of the replacement SIM.

How to Check If an Unknown SIM Is Registered on Your CNIC

If you suspect that an additional SIM has been issued using your CNIC, check your record through PTA first.

You can use the online SIM Information System or send your CNIC to 668. PTA’s cybersecurity guidance specifically recommends checking the number of SIMs issued in your name and blocking illegally issued SIMs.

What to do if you find an unknown SIM

Check the SIM count against your CNIC.
Identify the relevant network.
Contact that network through its official channel.
Explain that you do not recognize the connection.
Complete the required identity verification.
Ask about the procedure for blocking or disowning the unauthorized SIM.
Keep any complaint/reference number for your records.

Do not try to obtain private subscriber information through unofficial SIM databases.

Is There a Universal Code to Check SIM Registration Date?

No.

There is no single official code that publicly displays the exact registration date of every Jazz, Zong, Ufone, or Telenor SIM.

The 668 service is for checking SIMs associated with your CNIC, while detailed information about a particular connection has to be handled by the relevant operator.

Can You Check the SIM Registration Date Online for Free?

Not through PTA’s public SIM Information System.

You can check how many SIMs are registered against your CNIC online, but the public system does not present an exact historical registration date for each number.

If an unofficial website claims it can instantly reveal the exact registration date of any Pakistani mobile number, do not assume that the information is an official PTA record.

For your own number, the safer route is:

PTA check → identify the network → contact the operator → request the original registration/activation record.

What You Should Have Before Contacting Your Network

Keep these details ready:

Required information	Why it matters
Original CNIC	Identity verification
Mobile number	Identifies the connection
Network name	Sends the request to the right operator
Approximate purchase date	Helps with older records
SIM replacement details	Helps distinguish original registration from replacement

The operator may require additional verification before discussing subscriber information.

Conclusion

PTA’s 668 service is useful when you want to see how many SIMs are registered against your CNIC. It does not show the exact date on which a SIM was registered.

For the registration or activation date of a specific number, contact its network and ask them to check the subscriber record. If the SIM has been replaced before, also confirm whether the date is for the original registration or the replacement SIM.
