# Pakistan A2P SMS in 2026: PTA sender IDs, the 3627 Do Not Call Register, and the Corporate SMS market review

> Pakistan's A2P rules come from the PTA's anti-spam regulations: approved short codes and sender IDs, consent before marketing, the 3627 Do Not Call Register and business-hours delivery. In June 2026 the PTA also proposed treating Corporate SMS as its own regulated market.

To send A2P SMS in Pakistan you need a sender identity — a short code or an alphanumeric ID — approved through a cellular operator or a PTA-licensed aggregator, individual consent before any marketing, respect for the national Do Not Call Register on short code 3627, and promotional delivery within normal business hours. In June 2026 the Pakistan Telecommunication Authority (PTA) also proposed declaring Corporate SMS a separate relevant market, a step towards regulating what operators charge for it.

This guide sets out the rules as the PTA wrote them, what the consultation says, and a practical checklist for banks, fintechs, e-commerce brands and international apps with Pakistani users. Last reviewed: 26 September 2026.

## Key takeaways

- A2P SMS in Pakistan is governed by the PTA's Protection from Spam, Unsolicited, Fraudulent and Obnoxious Communication Regulations, 2009, as amended in December 2022.
- Marketing messages go out through approved short codes or alphanumeric IDs allocated by the Authority, under an agreement with an operator or a licensed SMS aggregator.
- Individual consent must be sought, in English and Urdu, before marketing; the sender keeps the consent record.
- Subscribers block telemarketing by registering on the Central Do Not Call Register via short code 3627.
- Operators must ensure opted-in promotional messages are received within normal business hours.
- On 4 June 2026 the PTA published a consultation proposing Corporate SMS as a separate relevant market, finding that each operator holds significant market power over SMS termination on its own network.

## Who regulates A2P SMS in Pakistan?

The PTA, under the Pakistan Telecommunication (Re-organization) Act, 1996. The operative rulebook for commercial SMS is the Protection from Spam, Unsolicited, Fraudulent and Obnoxious Communication Regulations, 2009 (S.R.O. 713(I)/2009), substantially rewritten by the Second Amendment Regulations, 2022 (S.R.O. 2402(I)/2022, published in the Gazette of Pakistan on 31 December 2022). The amended regulations take their definition of "spamming" from section 25 of the Prevention of Electronic Crimes Act, 2016 (PECA).

The regulations work through the operators. Each cellular operator must run a standard operating procedure for unsolicited communication, register telemarketers, maintain the Do Not Call Register, and act against repeat offenders.

## Who does what in Pakistan's A2P chain?

| Party | Role under the PTA rules |
|---|---|
| PTA | Regulator; allocates short codes and alphanumeric IDs; receives SLAs on demand; now reviewing Corporate SMS tariffs |
| Cellular mobile operators (Jazz, Zong, Telenor Pakistan, Ufone) | Terminate the traffic; register telemarketers; run the anti-spam SOP and the Central Do Not Call Register |
| CVAS licensees and SMS aggregators | Short-code holders that carry enterprise traffic under back-end agreements with the operators |
| Telemarketers and enterprises | Seek and keep individual consent; send only through approved short codes or IDs; honour opt-outs |

## How do I register a sender ID in Pakistan?

The amended regulations require telemarketers to enter into service-level agreements with SMS aggregators or operators that specify the services provided to subscribers "through short codes / alphanumeric IDs allocated by the Authority". Messages must be disseminated through approved short codes, or alphanumeric IDs mapped against short codes. In practice that means the sender identity is set up through an operator or a licensed aggregator, not by the sender alone.

1. Choose the identity: a short code, or an alphanumeric ID that clearly names your brand. Check it in our [sender ID validator](https://www.broadnet.me/tools/sender-id-validator).
2. Contract with an operator or a PTA-licensed aggregator and sign an SLA that states what you will send and how.
3. Supply company documents for the approval. Requirements vary by operator, so confirm the current list at onboarding.
4. Keep marketing and transactional traffic on separate identities so a marketing complaint cannot interrupt your OTPs.
5. Plan for five to ten business days for approval through BroadNet's operator routes (see the [Pakistan coverage page](https://www.broadnet.me/coverage/pakistan)).

Traffic that bypasses this chain — international grey routes that arrive as P2P — is what operator filters are built to stop. Our explainer on [grey routes](https://www.broadnet.me/answers/what-is-grey-route-sms) and the [direct vs grey routes guide](https://www.broadnet.me/blog/direct-routes-vs-grey-routes-a2p-sms) explain why it costs more than it saves.

## What is Pakistan's DNCR (3627)?

The Do Not Call / SMS Register (DNCR) is, in the regulation's words, a database maintained centrally by the operators of subscribers who have asked not to receive unsolicited communication — expressly including A2P promotional and telemarketing SMS and calls. The operators must run a consolidated Central Do Not Call Register (C-DNCR) and give every subscriber the option to register or unregister through short code 3627, which the Authority designated.

The regulation defines unsolicited communication as promotional or marketing information sent to people who have not consented and whose details are recorded in the C-DNCR. For senders the practical rule is simple: suppress registered numbers from marketing and keep your own opt-out list in sync. Our note on [handling SMS opt-outs](https://www.broadnet.me/answers/how-to-handle-sms-opt-outs) covers the mechanics.

## What are the consent and timing rules for promotional SMS?

| Requirement | Applies to | Since | Source |
|---|---|---|---|
| Seek individual consent by message in English and Urdu before marketing | Telemarketers sending through an SMS aggregator (short-code holder) | Gazette of 31 Dec 2022 | Spam Regulations Reg. 6(1)(a)(i), as amended |
| Keep a record of each individual consent | Telemarketers | Gazette of 31 Dec 2022 | Reg. 6(1)(a)(ii) |
| Offer an option to unsubscribe from promotional messages | Anyone engaged in direct marketing | Gazette of 31 Dec 2022 | Reg. 4(3) |
| Opted-in promotional messages received within normal business hours | Operators (and so their senders) | Gazette of 31 Dec 2022 | Reg. 4(3), proviso |
| Send only through approved short codes or alphanumeric IDs | Telemarketers and enterprises | Gazette of 31 Dec 2022 | Reg. 6(1)(b) |
| Registration of telemarketers | Operators | Gazette of 31 Dec 2022 | Reg. 8(1) |
| Register/unregister on the C-DNCR via 3627 | Subscribers; operators provide it | Gazette of 31 Dec 2022 | Reg. 7 |

The regulation says "normal business hours" without fixing the clock times, so agree the exact window with your operator or aggregator. The consent wording they prescribe is also bilingual: subscribers reply to receive marketing, or send a message to 3627 to refuse it.

## What happens to senders who spam?

The amended regulations give operators an escalation path for obnoxious communication: a first warning, then suspension of the originating subscription no later than 24 hours after a repeat complaint, a blacklist, and — for further repeats — permanent blocking with the user's details placed on a blacklisted-antecedents list. A suspended subscription can only be restored with the Authority's approval and a written undertaking. Every operator must also run an anti-spam filter that is regularly updated, may not be used anti-competitively, and applies to on-net and off-net messages alike.

## What is PTA's Corporate SMS market consultation?

> On 4 June 2026 the PTA published a "Consultation Paper on Identification of Corporate SMS as a Relevant Market for SMP Determination", with comments due by 19 June 2026. It is a proposal, not a decision; at the time of writing we had not seen a final determination published.

According to the paper, enterprises, financial institutions and service providers asked the PTA to intervene because operators charge significantly more for Corporate SMS than for person-to-person SMS on the same infrastructure. The PTA's preliminary view is that Corporate SMS — bulk messaging for alerts, transaction notifications, promotional campaigns and government messaging, sold directly by operators or through CVAS licensees and aggregators — is a distinct market.

- Demand side: for OTPs and banking alerts, SMS reaches every subscriber without data, a smartphone or an app, so OTT messaging, e-mail and push are complements rather than substitutes.
- Supply side: aggregators cannot deliver on their own; they depend on each operator for termination, so they cannot restrain operator pricing.
- Market power: each operator has exclusive control of SMS termination to its own subscribers — a 100% share of its own termination market — so the PTA considers that each operator holds significant market power (SMP) for Corporate SMS termination on its network.
- Data request: operators must supply audit-certified average rates and revenues for 1 January 2023 to 31 December 2025, split into banking transactional, banking marketing/information, and other sectors, for direct contracts and aggregator traffic.

An SMP finding is what normally allows a regulator to impose remedies such as tariff controls. Whether and how the PTA does that is still open, so budget on current rates and watch for the determination.

## Is SMS or WhatsApp better for OTP in Pakistan?

The PTA's own consultation makes the case for SMS: it is the only channel that reaches every mobile subscriber regardless of device or data. The cost pressure the consultation describes is also why many teams add a second channel for users who have WhatsApp installed and keep SMS as the universal fallback. [MyOTP](https://www.broadnet.me/products/myotp) and our [OTP API](https://www.broadnet.me/products/otp) route each verification to the channel you choose and fall back automatically; the [Pakistan SMS pricing page](https://www.broadnet.me/pricing/sms/pakistan) has current rates.

## Compliance checklist for A2P SMS in Pakistan

1. Send only through an operator or PTA-licensed aggregator under a written SLA — never over grey routes.
2. Register a short code or alphanumeric ID that names your brand; keep separate identities for marketing and OTP.
3. Collect individual, bilingual (English and Urdu) consent before marketing and keep the record.
4. Suppress C-DNCR registrations and your own opt-outs from every promotional send.
5. Include an unsubscribe option in promotional messages and deliver them only within normal business hours.
6. Keep OTPs and alerts free of promotion so they remain transactional.
7. Track the PTA's Corporate SMS determination and revisit pricing assumptions when it lands.

## Frequently asked questions

### How do I register a sender ID in Pakistan?

Through a cellular operator or a PTA-licensed SMS aggregator. The PTA's regulations require marketing traffic to use short codes or alphanumeric IDs allocated by the Authority, under an SLA that describes the service. Expect to supply company documents; confirm the current list with the operator.

### What is the 3627 Do Not Call Register in Pakistan?

It is the Central Do Not Call Register (C-DNCR) that operators must maintain. Subscribers register or unregister through short code 3627, and promotional messages to people who have not consented and are on the register count as unsolicited communication.

### What hours can I send promotional SMS in Pakistan?

The amended regulations require operators to ensure opted-in promotional messages are received within normal business hours. They do not fix the clock times, so agree the exact window with your operator or aggregator. OTPs and transactional alerts are not promotional.

### Do I need consent to send marketing SMS in Pakistan?

Yes. Telemarketers sending through an SMS aggregator must seek individual consent by message, in English and Urdu, before sending marketing, and must keep a record of each consent in case of dispute. Every promotional message must also offer a way to unsubscribe.

### What is PTA's Corporate SMS relevant-market consultation?

A June 2026 PTA paper proposing that Corporate SMS be treated as a separate relevant market. It finds that each operator controls SMS termination to its own subscribers and so holds significant market power, and asks operators for audit-certified rate and revenue data for 2023 to 2025.

### Why are bank OTP SMS costs a concern in Pakistan?

Stakeholders told the PTA that operators charge far more for Corporate SMS than for person-to-person SMS on the same infrastructure. Banks depend on SMS for authentication and alerts, and the PTA's consultation finds few substitutes, which is why it is examining operator market power.

### Can foreign companies send OTP SMS to Pakistan?

Yes, through a provider with operator or licensed-aggregator routes into Pakistan and an approved sender identity. The consent and DNCR rules apply to marketing; OTPs must stay free of promotional content to remain transactional.

### What happens if a sender keeps sending spam in Pakistan?

After a first warning, operators must suspend the originating subscription within 24 hours of a repeat complaint and blacklist it. Further repeats lead to permanent blocking, and restoring a suspended subscription needs the Authority's approval and a written undertaking.
