FAQ AIS & MMSI Registration in Malaysia

What is AIS?

AIS (Automatic Identification System) is a tracking system used on boats and ships for collision avoidance and maritime safety. It works by broadcasting a vessel’s identity, position, course, speed, and other vital data in real-time over VHF radio frequencies.

This information is received by:

• Other vessels nearby (to avoid collisions)

• Shore-based AIS stations

• Satellite systems (for offshore tracking)

There are two main types:

• Class A AIS: Mandatory for commercial vessels (SOLAS compliant).

• Class B AIS: Designed for recreational boats and smaller commercial vessels.

Why is AIS Required?

While AIS is not mandatory for all private yachts in Malaysia, it is highly recommended and often required for:

• International cruising — Many countries expect arriving vessels to be AIS equipped. Thailand and Indonesia requires your AIS is turned on at all times.

• Participation in rallies/regattas

• Offshore navigation — Especially in busy shipping lanes (like the Malacca Strait).

• Enhanced safety — It allows nearby vessels and authorities to see you, even in poor visibility or at night.

To activate AIS on your vessel, you need a unique MMSI number.

What is an MMSI Number?

MMSI (Maritime Mobile Service Identity) is a unique 9-digit number assigned to your vessel that identifies it during digital communications — including AIS, DSC (Digital Selective Calling) radios, EPIRBs, and more.

Once programmed into your AIS transceiver, your MMSI will be permanently tied to your boat.

How to Apply for MMSI & AIS Registration in Malaysia

As of 2025, here’s the general procedure for Malaysian-flagged boats:

Step-by-Step Process:

1. Prepare Documentation

You'll need:

• Copy of your boat’s registration certificate (Langkawi, Sabah, Sarawak, etc.)

• Your IC/passport (if Malaysian or foreigner owner)

• Proof of ownership / Bill Of Sale

• Equipment details (make/model of AIS unit, radio, etc.)

2. Contact the MCMC (Malaysian Communications and Multimedia Commission)

MCMC is the body responsible for issuing MMSI numbers in Malaysia. We provide their contact at the bottom of this article.

3. Pay Licensing Fees

Fees vary based on the type of license and equipment. Expect a Ship Station License fee (approx. RM 60–150 annually).

4. Receive Your MMSI

Once approved, you will be assigned a unique MMSI, which must then be programmed into your AIS transceiver by a certified installer or technician (some models allow DIY entry once).

5. AIS Activation & Testing

Once your MMSI is programmed, activate your AIS unit. Test to ensure:

• Your signal is being received by nearby ships

• You're visible on AIS tracking apps (like MarineTraffic)

Notes for Foreign Cruisers in Malaysia:

If your boat is foreign-flagged, retain your MMSI from your country of registration. You don’t need a Malaysian MMSI. However, if you re-register your boat under a Malaysian flag, you must apply for a new MMSI locally through MCMC.

Important Tips:

• Don't reuse an MMSI from another vessel — they are unique and non-transferable.

• Once programmed, the MMSI in some AIS devices is non-editable without special tools — double-check before inputting.

• Renewal is typically annual, and failure to renew may cause your MMSI to be deactivated.
