How to Check How Many SIM Cards Are Registered on Your Aadhaar (2026)

Most people have no idea how many SIM cards are registered on their Aadhaar. You buy a connection, you use it for a year, you stop recharging, and it quietly stays on the books in your name. Multiply that by a decade of job changes and city moves and it is not unusual to find three or four numbers you had forgotten, and occasionally one you never asked for at all. That last case is the dangerous one, because a connection issued against your identity can be used for fraud that traces back to you.

The Department of Telecommunications runs a free service that shows you the list and lets you disown anything that is not yours. It began life as TAFCOP and now sits inside the Sanchar Saathi portal as the Know Your Mobile Connections service. This guide from TechLein explains how to run the check, what the results actually mean, how many connections you are allowed, and what happens after you flag one.

Key takeaways

• The Know Your Mobile Connections service on Sanchar Saathi lists the connections registered against your identity, free of charge.
• An individual is generally allowed up to nine mobile connections nationwide, with a lower cap in certain regions.
• You can flag a number as not yours, or as one you no longer need, and track the request with a ticket ID.
• The check needs only a working mobile number and an OTP, not your Aadhaar number.

Why this check is worth ten minutes

Every mobile connection in India is issued against a proof of identity, usually Aadhaar. When someone obtains a connection using your documents, either through a careless retailer or a deliberately fraudulent one, that number sits in your name in the operator’s records and in the national database. If it is then used for spam, fraud calls or worse, the trail leads to you first.

The more mundane risk is simply forgotten connections. An unused number that eventually gets recycled and reissued to a stranger is a problem if it is still the recovery number on an old email account or a bank record. Auditing the list gives you a chance to close what you do not need and update what you do.

How many SIM cards can be registered on one Aadhaar

The Department of Telecommunications caps the number of mobile connections a single individual can hold. The general limit across most of the country is nine connections. In certain licensed service areas, including Jammu and Kashmir, Assam and the North East, the cap is lower. Machine-to-machine connections are counted separately under a different regime.

Two points about the cap are commonly misunderstood. It applies per person, not per operator, so nine is the total across Jio, Airtel, Vi, BSNL and any other provider combined. And it is a regulatory ceiling, not a target; there is no benefit to holding connections you do not use.

How to check the connections in your name

The service lives on the Sanchar Saathi portal run by the Department of Telecommunications, and is also available inside the official Sanchar Saathi app. Do not use third-party sites that reproduce the form; there is no reason for any private site to collect your mobile number for this.

1. Open the Sanchar Saathi portal in your browser, or the official app if you have installed it.
2. Find the citizen-centric services section and select the option to know your mobile connections.
3. Enter the ten-digit mobile number you want to check from and the captcha shown on the page.
4. Request the OTP and enter the code that arrives by SMS. You must have the SIM in hand.
5. The portal displays the list of connections registered against the identity linked to that number.
6. Review each entry. Numbers are usually shown partially masked, which is enough to recognise your own.
7. For anything you do not recognise, use the action option next to it to report the connection.

One caveat worth setting expectations on: the list reflects what the operators have reported against your identity, and there can be lag or gaps, particularly for very old connections or those taken in a different licensed service area. Treat a clean result as reassuring rather than as an absolute guarantee.

What the reporting options mean

Each row on the results page comes with a choice, and picking the right one matters because they trigger different processes at the operator’s end.

Not my number

Use this only when the connection was genuinely never taken by you. It starts a verification at the operator, which will typically attempt to contact the current user and validate the documents on file. If the connection turns out to be fraudulent, it is disconnected.

Not required

This is for a number that is legitimately yours but which you no longer want. It is the clean way to surrender an old connection rather than letting it lapse and get recycled while your accounts still point at it.

Required

Some interfaces show this for numbers you are actively using but which appear flagged. Selecting it simply confirms that you want to keep the connection.

In every case the portal issues a ticket reference. Save it. There is a separate status-tracking option on the same site where you enter the ticket ID and see whether the request is open, under process or closed.

What happens after you report a connection

The request goes to the telecom service provider that issued the number. The operator re-verifies the customer acquisition form and the identity document used at activation. If the documents do not hold up, the connection is deactivated. Where the case looks like organised misuse of identity documents, it can be escalated further.

Resolution is not instant. Expect the process to take a few weeks rather than a few days, and check the ticket status periodically instead of filing repeat complaints, which only resets the queue. If a fraudulent connection has already caused you a specific harm, such as a financial loss, report that separately through the cyber crime channels rather than relying on the disconnection request alone.

Related checks worth running at the same time

The connections audit is one of several tools on the same portal, and it makes sense to run through the others while you are logged in. The fraud reporting facility lets you flag suspicious calls and messages, and the device-blocking service handles a lost or stolen handset. Our Sanchar Saathi guide walks through each of those in turn, and the specific procedure for a stolen phone is covered in detail in our explainer on how to block a lost or stolen phone using CEIR.

If the audit turns up an old number that you want to keep but no longer carry a physical SIM for, converting the active one to an eSIM is often tidier than juggling handsets; our complete eSIM guide for India covers how each operator handles the switch. And if the OTP for this check never arrives because the mobile number on your Aadhaar record is stale, our guide on how to update Aadhaar details explains what that fix involves.

Reducing the risk in the first place

Most fraudulent connections start at the point of sale. A retailer takes an extra fingerprint impression or an extra photocopy and uses it later. Two habits cut this down substantially. First, use the biometric lock feature in the mAadhaar app so your fingerprints cannot be used for authentication without your explicit unlock. Second, prefer offline eKYC or a Virtual ID over handing across an Aadhaar photocopy, and if you must give a copy, write the purpose and date across it.

Beyond telecom, keeping your identity documents out of casual circulation is the same discipline that protects your accounts generally. Our online safety guide for India covers the wider picture, and the practical steps for securing your Android phone matter because the handset is where most of the damage from a compromised number lands. Storing verified copies in DigiLocker rather than a WhatsApp chat also helps, and our complete DigiLocker guide explains how sharing works there.

Frequently asked questions

Do I need my Aadhaar number to run this check?

No. The service only asks for a mobile number and an OTP sent to it. Any site demanding your Aadhaar number for this is not the official one.

Will the portal show every connection ever issued to me?

It shows what operators have reported against your identity. Very old connections or those from another service area may not appear, so treat it as a strong indicator rather than a complete record.

How long does a disconnection request take?

Typically a few weeks, since the operator re-verifies the documents used at activation. Track the ticket ID instead of filing duplicates.

Can I check a number that is not in my hand?

No. The OTP goes to the number you enter, so you need the active SIM to complete the check.

What if I already hold nine connections and need another?

You will need to surrender one first. Use the not required option on the portal to close a connection cleanly before applying for a new one.

The bottom line

Checking the SIM cards registered on your Aadhaar takes less time than a recharge and occasionally turns up something genuinely worth acting on. Even when it does not, closing two forgotten connections removes numbers that could be recycled while your old accounts still point at them.

Make it an annual habit, run it alongside a quick review of which of your accounts still use an old number for OTPs, and turn on Aadhaar biometric lock so the next careless retailer cannot add to the list. Those three steps together cover most of the ways an identity document turns into someone else’s phone connection.
