MCMC in practice: CLI verification, Sender ID registration and the DNO list for A2P SMS traffic into Malaysia

The Malaysian Communications and Multimedia Commission (MCMC) administers the +60 numbering plan and the Sender ID regime under the Communications and Multimedia Act 1998. Four mobile networks carry the country: Maxis, Celcom Digi (the merged Celcom + Digi entity), U Mobile and Yes (YTL Communications). 4notify routes over direct tier-1 interconnects with all four, registers alphanumeric Sender IDs and verifies the DNO list at the API edge. Sabar sikit — traceability and delivery, no grey-route.

Share: ~35% · P50: 2.5 s

Largest postpaid base and the most enterprise A2P contracts; tier-1 preferred for regulated sectors.

Celcom Digi

Post-merger Celcom + Digi combined: the largest subscriber base in Malaysia, strong throughput for high-volume marketing.

U Mobile

Growing operator with sharp digital-native traction; alphanumeric Sender ID well supported.

Yes (YTL Communications)

Share: ~10% · P50: 3.1 s

Five-step MCMC compliance chain

    MCMC notification + carrier contracts

    4notify is a notified A2P delivery provider with MCMC and holds Sender ID contracts with Maxis, Celcom Digi, U Mobile and Yes.

  2. 02

    On every commercial message the keywords STOP and BERHENTI are processed within 3 days and propagated into the suppression list.

Frequently asked

Is a Malaysian Sdn Bhd required to send SMS into Malaysia?

No. 4notify operates the tier-1 interconnects from European infrastructure. Sender ID registration itself requires a brand with provable ownership (trademark or SSM business registration); we assist with the operator filings at Maxis, Celcom Digi, U Mobile and Yes.

What is the penalty for impersonating a reserved Sender ID?

Impersonating a DNO Sender ID (banks, federal agencies, emergency services) can trigger MCMC enforcement under the Communications and Multimedia Act 1998 and liability for impersonation fraud. That is why 4notify verifies the DNO list before every send.

How long does Sender ID activation take?

Typically 5-10 business days. Celcom Digi tends to be the fastest; Yes can take an extra 1-2 days because of additional internal review.
