A2P SMS regulations in Nigeria.
Compliance with the NCC.
A2P SMS in Nigeria is regulated by the NCC (Nigerian Communications Commission). Subscribers opt out of unsolicited marketing through the national DND (Do Not Disturb) facility on the 2442 short code, commercial senders register a branded sender ID with the operators, and NCC guidelines govern unsolicited messages. Personal data is governed by the Nigeria Data Protection Act, 2023 (NDPA), enforced by the Nigeria Data Protection Commission (NDPC).
Who regulates A2P SMS in Nigeria?
Telecom services in Nigeria are regulated by the Nigerian Communications Commission (NCC) under the Nigerian Communications Act, 2003. The NCC issues guidelines and directives on unsolicited commercial messages and consumer protection, and enforces them through the mobile operators. Data-privacy obligations sit separately under the Nigeria Data Protection Act, 2023, overseen by the Nigeria Data Protection Commission (NDPC).
- Regulator: NCC (ncc.gov.ng).
- Governing law: Nigerian Communications Act, 2003.
- NCC guidelines cover unsolicited commercial messages.
- Data privacy: NDPA 2023, enforced by the NDPC.
The DND facility and the 2442 short code
Nigeria's defining consumer control is the national Do-Not-Disturb (DND) facility: subscribers text opt-out instructions to the short code 2442 to stop unsolicited marketing, and can choose full DND or partial category filtering. Operators must honour these preferences, and promotional messages to fully-DND subscribers are blocked. Senders must suppress DND-registered numbers from marketing campaigns.
- Subscribers manage marketing preferences via 2442.
- Full DND blocks all promotional SMS; partial filters by category.
- Operators must honour DND selections.
- Senders must suppress DND numbers from marketing.
Sender-ID registration
Commercial A2P messages are sent under a registered, branded alphanumeric sender ID that identifies the business, provisioned through the mobile operators (MTN, Airtel, Glo and 9mobile) via a corporate SMS agreement. The sender ID should reflect the registered brand, and content is typically reviewed against the declared use case. Unregistered sender IDs and international grey-route traffic are liable to be blocked or filtered.
- Branded alphanumeric sender ID registered through the operators.
- Operators: MTN, Airtel, Glo, 9mobile.
- Sender ID should match the registered brand name.
- Unregistered IDs and grey-route traffic are blocked/filtered.
- Since December 2020 the NCC has required every SIM to be linked to the subscriber's National Identification Number (NIN); lines without a verified link have been barred.
Promotional vs. transactional messages
Marketing/promotional SMS is subject to the DND facility, consent and opt-out rules, while transactional/service messages — OTPs, banking alerts, delivery and account notifications — are tied to an existing customer relationship and are generally not blocked by DND. Both are sent under a registered sender ID; keep promotional and transactional flows separate with their own consent records.
- Promotional: DND, consent and opt-out rules apply.
- Transactional/service (OTP, alerts): not blocked by DND.
- Both delivered under a registered sender ID.
- Keep marketing and transactional traffic separate.
Consent, opt-out and unsolicited messages
NCC guidelines require senders not to send unsolicited marketing to subscribers who have activated DND, and to provide clear opt-out. Beyond DND, the NDPA requires a lawful basis — generally consent — to process personal data for marketing, and individuals may object to direct marketing and withdraw consent. Every marketing message should identify the sender and offer a free, honoured opt-out, and senders should reconcile lists against DND.
- No unsolicited marketing to DND-activated subscribers.
- NDPA requires a lawful basis (usually consent) for marketing data.
- Individuals may object to direct marketing and withdraw consent.
- Provide a free opt-out and reconcile against DND.
Data protection: the NDPA 2023 and NDPC
Personal data used for messaging is governed by the Nigeria Data Protection Act, 2023 (NDPA), which established the Nigeria Data Protection Commission (NDPC) and succeeded the earlier NDPR 2019 regime. The NDPA requires a lawful basis for processing, data-subject rights (access, rectification, erasure, objection), breach notification, and conditions on cross-border transfers. Larger data controllers face registration and compliance-audit obligations.
- Law: Nigeria Data Protection Act, 2023 (NDPA).
- Regulator: Nigeria Data Protection Commission (NDPC).
- Succeeded the earlier NDPR 2019 framework.
- Data-subject rights, breach notice and transfer rules apply.
- NDPA fines: up to the higher of NGN 10 million or 2% of annual gross revenue for data controllers of major importance (NGN 2 million or 2% for others).
Enforcement and operator landscape
Enforcement runs on two tracks: the NCC can fine operators and direct blocking for DND and unsolicited-message breaches, while the NDPC can impose penalties for unlawful processing of personal data. Nigeria has four mobile operators — MTN, Airtel, Glo and 9mobile — and reaching all subscribers means registering the sender ID with each. Confirm current registration fees, documents and timelines with your operator at onboarding.
- NCC: fines and blocking for DND / unsolicited-message breaches.

How to register a sender ID in Nigeria
What to prepare, who approves it and how long it takes. Send us the documents below and BroadNet coordinates the registration with the operators, the regulator or the registry, as the market requires.
- Who approves
- NCC-licensed aggregators and the four operators MTN, Airtel, Glo and 9mobile, under NCC rules. Content providers do not connect to the operators directly: the ID is registered through a licensed aggregator and whitelisted on each network.
- Typical lead time
- 5–10 business days once the paperwork is in
Document checklist
- Corporate Affairs Commission (CAC) certificate
- Tax registration
- Authorisation letter
- Sample message templates
- Traffic-type declaration
Steps
- 1
Choose the sender ID: alphanumeric, up to 11 characters, matching the brand on your CAC registration. Use one ID per use case per entity, and keep promotional and transactional traffic on separate sender IDs.
- 2
Check the category. Unlicensed lending, gambling and unlicensed pharma templates are blocked at the operator firewall. A licensed lender's sender ID is registered against its lending licence.
- 3
Send BroadNet the documents. A2P SMS reaches Nigerian operators only through an NCC-licensed aggregator, which files the ID with MTN, Airtel, Glo and 9mobile; BroadNet coordinates the filing during onboarding.
- 4
Approval typically takes 5–10 business days.
- 5
Send only within the registered use case. Every bulk message must carry the sender's registered ID. Marketing SMS goes only to opted-in recipients, is filtered against the NCC Do-Not-Disturb (DND) registry, and may be sent only between 8:00am and 8:00pm.
Common reasons for rejection
- A foreign sender trying to bind directly, without an NCC-licensed aggregator
- Restricted-category templates (unlicensed lending, gambling, pharma)
- Generic IDs such as INFO or ALERT
- A brand that does not match the CAC registration
- A sender ID that conflicts with a brand name already reserved on an operator's whitelist
