Corporate SIMs on NTN: Registration Rules for Businesses

Imagine opening a recovery notice for Rs. 626,360 in unpaid mobile bills, for 400 postpaid connections your company has never heard of. That's roughly what happened to one Pakistani company, and on 25 August 2026 PTA fined the operator involved Rs. 38.9 million over it. The case is a sharp reminder that corporate SIMs are not just a convenient way to give staff phones. They're a regulated category with their own paperwork, their own deadlines and their own traps. This guide explains how corporate SIMs on an NTN work, what PTA requires, how ownership changes and porting are handled, and how to keep your business from ending up on the wrong side of it. I'll also flag what I couldn't verify, because a lot of confident "corporate SIM" advice online has no official source behind it.

Four parties are involved in every corporate SIM, and confusion between them is where most problems start.

What "Corporate SIM" Means to PTA

The clearest official definition sits in PTA's MNP Porting Process Guidelines. A corporate account is a mobile connection, or set of connections, whose owner is a corporate entity that undertakes, on its official letterhead, responsibility for all financial matters related to the connection. Each connection must have a user designated by the authorised signatory of the entity.

The same document widens the term deliberately. For porting, "corporate" includes all types of business accounts sponsored by or paid for by a corporate, company or organisation. So it isn't only about big firms with hundreds of lines. A small business that pays for its staff's connections falls in the same family.

Where does the NTN come in? The National Tax Number is the tax identity of the business. Reports of PTA's 2026 enforcement order describe operators verifying "CNIC/NTN and organisational credentials" before bulk corporate issuance. I couldn't find PTA publishing a full checklist of NTN documents on its public pages, so the exact papers an operator asks for can vary. Treat the list below as the reported baseline, and confirm details with the operator's corporate team.

The Paper Trail

A detailed summary of PTA's August 2026 order lists what corporate SIM issuance requires under the Subscribers Antecedents Verification Regulations and the related SOP. This is the list businesses should be ready for.

1. A valid board resolution or authority letter from the organisation.
2. Identification and a CNIC copy of the authorised representative.
3. Verification of CNIC, NTN and organisational credentials.
4. The number of SIMs requested, which the operator must verify before bulk issuance.
5. End-user details, including name, CNIC and present and permanent address, declared within seven days of bulk issuance.
6. Complete SIM allocation and end-user mapping records, kept by the operator.

Because this is a summary of an order and not the regulation itself, I'd verify the details with your operator before relying on them. But as a working checklist for a business, it's a sensible one. Try it below to see how ready your paperwork is. The check runs in your browser, and nothing you tick is stored or sent.

The Seven-Day Clock

The most unusual requirement in the reported rules is a deadline. After a bulk issuance, the end-user details for each SIM have to be declared within seven days. If they aren't, the reported rules say the SIMs are to be blocked on the eighth day.

1. 0Day 0: IssuanceSIMs issued after the operator verifies the company and representative
2. 1–6Days 1–6: CollectGather each user's name, CNIC and addresses
3. 7Day 7: DeclareLast day to give end-user details to the operator
4. 8Day 8: BlockingSIMs without end-user credentials are to be blocked

The takeaway for a business is practical. Don't order a batch of SIMs and hand them out over a few weeks. Have your end-user list ready before the SIMs arrive, or you risk a wave of blocked connections in the middle of a busy period. The people holding those phones will also need valid CNICs, which is a good reason to check for anyone whose card is close to expiry, as our guide to expired CNICs and SIM blocking explains.

Personal CNIC vs Company NTN

For the personal side, our guides to 668, the cnic.sims.pk portal and MNP 667 cover each check.

The 400 SIMs Nobody Ordered

Here's the case that put corporate SIMs in the headlines. According to reports, Target Marketing (Pvt) Limited complained to PTA after a recovery agency demanded Rs. 626,360.48 for around 400 corporate postpaid connections that, it said, were registered in its name between June and August 2021 without its request, consent or authorisation. PTA called for Jazz's records under Section 23 of the Pakistan Telecommunication (Re-organization) Act, 1996.

PTA found Jazz's response incomplete. The records reportedly included an NTN certificate, an older business agreement naming a point of contact, a list of 400 SIMs and connection requests, but not the corporate authorisation documents and end-user credentials required. On 25 August 2026, PTA fined Jazz Rs. 38.9 million, with 30 days to pay. Jazz had argued, as reported, that the matter was a commercial and billing dispute and that SOPs lacked the force of the Act. PTA rejected both.

• Compliance doesn't end at onboarding. PTA said it extends to continuous monitoring, verification of end-user authenticity, traceability of SIM allocation and blocking where required information isn't provided in time.
• Responsibility can't be passed on. PTA said the operator remains accountable and can't shift responsibility to corporate customers, franchises, sales channels or representatives.
• A billing complaint and a regulatory duty run in parallel. A financial dispute doesn't excuse the operator from its regulatory obligations.

A note on sources, since it matters. The fine, the complaint and PTA's main findings were reported independently by several outlets, including TechJuice and Daily Pakistan, as well as PhoneWorld. The finer details, such as the list of required documents and the seven-day rule, come mainly from a summary of the order published by ICCI, a site developed by the complaining company. I haven't seen the order itself, so treat those details as reported, and read PTA's own record if you need exact wording. These are PTA's findings as reported, and the operator may contest them. What's not in dispute is the lesson for every business: your NTN can be used to open connections you know nothing about, and the first you hear may be a debt collector.

Changing Hands: When an Employee Leaves

People move on, but their company SIM often doesn't. PTA's guidelines describe how ownership changes for ported corporate numbers, and the logic is a good model for any business.

• From company to individual. The individual must have been the user designated by the company for the last 60 days, all outstanding dues on the related corporate account must be cleared, and the authorised signatory must issue an NOC on company letterhead with the company stamp. The person then completes biometric verification.
• From individual to company. The individual must be the designated user and issue an NOC confirming the change, and the authorised signatory must sign an application on letterhead with the stamp, confirming that the individual is associated with the company.

Both need the person in front of the counter for fingerprints, which is why our guide to biometric verification is worth a read before you go. Since a change of ownership also restarts the 60-day period before a number can be ported out, plan it ahead of any network switch. If a company SIM was mistakenly put on an employee's personal CNIC, moving it to the company is a legitimate use of this kind of process, but ask the operator which route applies to your SIM. Our guide to the name on a SIM explains how to see whose name a SIM is currently registered under.

Porting a Corporate Number

Switching networks works differently for a company. Instead of each employee texting 667, PTA's guidelines set out a letter-based process.

1. Write on company letterhead. The authorised contact sends a letter, following a PTA template, asking the current operator for the data needed to start porting.
2. Name the new operator's contact. The letter includes the recipient operator's MNP contact and the company's authorised contact.
3. Send it in the right order. A scanned copy goes first, and the hard copy has to reach the donor operator by close of business on the fourth calendar day.
4. Wait for the data. The current operator provides the information by close of business on the next working day after the electronic copy arrives.
5. Watch for name mismatches. For corporate customers, the company name has to match the operator's records, though spelling mistakes alone aren't a ground for rejection.
6. Cancel in writing if needed. Corporate subscribers can send a cancellation request to either operator before the number is switched.

The guidelines also give corporates one break: the rejection for not having used the 667 message service in the previous ten days doesn't apply to corporate accounts. The 60-day minimum subscription period still applies to newly activated or ported-in numbers, and unused prepaid balance on the number you leave isn't refunded. Our MNP 667 code guide covers the individual version of the process.

Do Company SIMs Count Against Employees?

This is the question I get asked most, and the honest answer is that I couldn't find an official statement. PTA's public FAQ describes the limit of five voice and three data SIMs per CNIC in terms of personal use. Corporate connections are registered in the company's name, with employees recorded as designated users. That suggests they're separate from an employee's personal allowance, but "suggests" isn't "confirms". Ask your operator how your company's connections are recorded against individuals.

What I can say with confidence is the risk on the other side. If a company SIM is registered on an employee's personal CNIC, it occupies that employee's allowance, makes them the person on record, and can leave them explaining it long after they've left the job.

Checking What's Registered in Your Company's Name

Individuals have SMS 668 and the portal. Businesses have less. PTA's public checks are described in terms of a CNIC, and I found no official public NTN lookup. That doesn't leave you helpless, though.

• Ask the operator's corporate team in writing. Request a list of all connections registered under your NTN, with the end-user mapping, and get a reference number.
• Read your invoices closely. Connections you don't recognise are the earliest warning sign. In the reported case, the first alert was a recovery notice.
• Reconcile against your own register. Compare the operator's list with your SIM allocation record every quarter.
• Escalate quickly if something is unauthorised. Report to the operator, then to PTA on 0800-55055 or through its complaint portal. For identity misuse, contact NCCIA on 1799.

Start from your operator's official pages: Jazz, Zong, Ufone or Onic. Former Telenor customers should use Ufone's channels after the July 2026 merger, and Onic stopped new SIM sales after a PTA order on 11 September 2026, so use it for existing service only. Our Zong SIM owner details guide shows what a network-specific check looks like.

Please Don't Use Employees' CNICs

The shortcut is tempting: a manager needs ten SIMs, so they're registered on staff CNICs and the company pays the bills. It's a bad idea for three reasons. Each SIM uses up the employee's personal allowance. The employee becomes the registered person for everything the SIM does. And registering SIMs on someone's identity without their informed consent can raise identity-misuse questions under section 16 of PECA 2016, which covers using another person's identity information without authorisation. That's general information, not legal advice.

The clean alternative is what this whole guide describes: register under the company, with a designated user for each SIM, and keep the records. It protects the business, the employee and the operator at the same time. If you've already put company SIMs on personal CNICs, ask the operator about moving them to the company, and use our CNIC SIM check guide to see what's on each person's CNIC.

A Compliance Calendar

Corporate SIMs on NTN: FAQs

What is a corporate SIM in Pakistan?

A connection whose subscriber is a company, which takes responsibility for it on its official letterhead. Each connection has a user designated by the company's authorised signatory, according to PTA's MNP guidelines.

What documents are needed to register corporate SIMs on an NTN?

Reports of PTA's 2026 order list a board resolution or authority letter, the authorised representative's CNIC, verification of CNIC/NTN and company credentials, and end-user details. Exact requirements can vary, so confirm with the operator's corporate team.

What is the seven-day rule for corporate SIMs?

As reported, end-user details such as name, CNIC and addresses must be declared within seven days of bulk issuance, and SIMs without them are to be blocked on the eighth day. Confirm the current rule with your operator.

Who is responsible if a corporate SIM is misused?

PTA's reported findings say the licensed operator remains accountable for compliance and can't shift that to customers or sales channels. The company is still the registered subscriber and answers for the connection's financial matters, so keep your own records.

How can I check SIMs registered under my company's NTN?

PTA's public checks are described in terms of a CNIC, and I found no official public NTN lookup. Ask the operator's corporate team in writing for the list of connections and end-user mapping.

Do corporate SIMs count toward an employee's SIM limit?

I couldn't find an official statement. The personal limit of five voice and three data SIMs is described for personal use, and corporate connections are registered to the company. Ask your operator how they're recorded.

What happens when an employee leaves?

Reassign or return the SIM and update the records. If ownership moves from the company to the individual, PTA's guidelines for ported numbers require, among other things, a company NOC on letterhead with a stamp, cleared dues and biometric verification.

How do I port a corporate number?

Through a letter on company letterhead following a PTA template, sent to the current operator directly or through the new operator's MNP contact. Data is due by the next working day after the scanned copy arrives.

Can I register company SIMs on employees' CNICs?

It's a bad idea. Each SIM uses the employee's personal allowance and makes them the person on record. Registering SIMs on someone's identity without informed consent can also raise questions under PECA section 16.

What if SIMs were registered in my company's name without permission?

Report to the operator, then to PTA on 0800-55055 or through its complaint portal. A 2026 PTA order followed exactly this kind of complaint. For identity misuse, contact NCCIA on 1799.
