Understanding SIM Owner Details in Bangladesh

If you have ever wondered who owns a particular mobile number or how to verify sim owner details in bangladesh, you are not alone. Millions of people in Bangladesh need to check sim owner details for personal safety, business verification, or simply to confirm that a SIM card is registered under their own name. In Bangladesh, every mobile connection – whether Grameenphone, Robi, Banglalink, Airtel, or Teletalk – must be linked to a valid National ID (NID) as mandated by the Bangladesh Telecommunication Regulatory Commission (BTRC). This guide explains all legal, ethical, and practical ways to obtain sim owner details in Bangladesh, including official USSD codes, operator apps, and BTRC tools.

Why You Might Need Sim Owner Details in Bangladesh

Knowing the registered owner of a mobile number can help in many situations:

Verify unknown callers – If you receive repeated calls from an unfamiliar number, checking ownership can confirm if it is a legitimate contact or a potential scammer.
Confirm business identities – Before making a payment or sharing sensitive information, verifying the SIM owner can prevent fraud.
Check your own registration – Ensure your SIM is properly registered under your name and NID, as per BTRC rules.
Track lost or stolen phone numbers – If your SIM is misused, knowing the registered details helps in reporting to authorities.
Family and employee management – Parents may want to check SIMs registered under their NID for family members, or employers can verify corporate connections.

While checking someone else’s sim owner details without consent is restricted by privacy laws, there are legal methods to verify registration status for your own numbers and, in some cases, with the owner’s permission.

Official USSD Codes to Check SIM Owner Details in Bangladesh

The fastest and most reliable way to see sim owner details in Bangladesh is by using USSD codes provided by each operator. These codes work without an internet connection and display your own registered name and NID information.

Grameenphone (GP) SIM Owner Check

To view GP sim owner details:

Dial *111# from your GP number.
Select option “3” (Services) or follow the menu.
Choose “My Account” then “My Information”.
Your registered name, activation date, and NID details appear on screen.

An alternative code is *121*1*1# which directly shows your SIM registration status.

Robi SIM Owner Check

Robi users can check their owner details by dialing *222#:

Dial *222# and press call.
Select option “1” (My Account).
Choose “My Info” to view the registered owner name.

Another method: dial *8444*88# to receive a USSD response with your registration status, or send an SMS with “ER” to 8444.

Banglalink SIM Owner Check

Banglalink customers can verify sim owner details in bangladesh using:

Dial *551# from your Banglalink number.
Select “My Account Info” from the menu.
Choose “My Details” to see the registered name.

You can also dial *166# and navigate to account information.

Airtel SIM Owner Check

Airtel Bangladesh users:

Dial *121# from your Airtel number.
Select “My Offer” (option 1).
Then choose “My Account” and follow prompts to view owner details.

Your registered name and NID will be displayed.

Online Methods: Operator Apps and Websites

Every major operator in Bangladesh provides a self-care app where you can view your sim owner details after logging in. These apps often show additional information like usage history and billing.

Grameenphone – MyGP app (Android/iOS): go to “My Account” → “Profile” to see your registered name and NID.
Robi – MyRobi app: under “Account Info” you can view owner details.
Banglalink – Banglalink Shop app or My Banglalink portal: select “My Profile”.
Airtel – Airtel Bangladesh app: check “My Account” → “Profile”.
Teletalk – Teletalk self-care portal: log in and view personal details.

These apps require an OTP sent to the registered number, so you can only check your own SIM. For checking someone else’s sim owner details in bangladesh, you would need their explicit consent or a legal authority order.

BTRC SIM Registration Check: How Many SIMs Are Under Your NID?

The Bangladesh Telecommunication Regulatory Commission (BTRC) offers a service to check how many SIM cards are registered under your National ID. This is crucial to prevent identity theft and to ensure no one has fraudulently used your NID to obtain a SIM.

Dial *16001# from any mobile phone.
You will receive an SMS listing all numbers registered under your NID, along with operator names and registration dates.
If you see any SIM you did not authorize, immediately contact the respective operator or BTRC to block it.

This BTRC service is free and works across all operators. Use it regularly to verify your sim owner details and keep your identity safe.

Limitations of Checking SIM Owner Details for Others

While it is easy to check your own sim owner details in bangladesh, finding the owner of another person’s number is restricted under the Digital Security Act and privacy regulations. SIM databases are not publicly accessible. Third-party apps that claim to show owner names for any Bangladeshi number should be treated with caution; many are scams or contain outdated, unreliable information.

Legitimate methods to identify an unknown caller in Bangladesh include:

Truecaller – crowdsourced caller ID app, but it only shows names that users themselves have saved.
Operator caller ID services – Grameenphone, Robi, and others offer paid caller identification for incoming calls.
BTRC complaint portal – if you receive harassing calls, you can file a complaint with BTRC, and they may assist in identifying the owner.
Police assistance – for serious threats or fraud, law enforcement can request SIM owner details from operators with a court order.

Remember: never share your NID or OTP with anyone. Scammers often pose as operator representatives to steal your sim owner details.

How to Protect Your SIM Registration Information

Keeping your sim owner details secure is vital. Follow these practices:

Regularly check BTRC’s *16001# service to see all SIMs under your NID.
If you lose your phone, immediately block the SIM by contacting your operator’s helpline.
Do not let shops register SIMs for you without your presence; insist on doing the NID verification yourself.
Change your SIM’s PIN code and enable two-factor authentication where possible.
Report any suspicious activity to the BTRC hotline or your operator’s fraud department.
