San Marino MMSI number registration is usually included with your yacht registration package. You get an MMSI number, an AIS number, and a call sign together. The process is straightforward and offers a complete, all-in-one solution.
What Is an MMSI Number and Why Do You Need One?
An MMSI (Maritime Mobile Service Identity) is a unique nine-digit number for your boat. It identifies your vessel on radio and AIS systems. You need it for safety communications like Digital Selective Calling (DSC) and for your AIS transponder. Without an MMSI, your radio and AIS cannot send your identity in an emergency, which is critical for VHF radio, AIS, and distress communication. It is a legal requirement for vessels with VHF radios and AIS in many jurisdictions.
San Marino’s inclusion of the MMSI in the registration package is particularly advantageous because it eliminates the need for a separate application, ensuring you have this essential safety identifier from day one.
San Marino MMSI Registration: Included with Your Flag Registration
San Marino boat registration includes the AIS and MMSI radio license automatically. You do not need to apply separately. The license is issued together with your registration package. This saves you time and hassle. Other flags often require a separate application after registration. San Marino bundles it all in one step. The package includes your MMSI number, AIS number, and call sign.
How Fast Can You Get Your San Marino MMSI License?
It is important to distinguish between the full San Marino registration and the MMSI license alone. The full San Marino registration, which includes the MMSI, takes a minimum of 2 months to process. Once your registration documents are complete and approved, the MMSI is issued as part of that package. If you only need an MMSI license and do not require a full San Marino registration, processing can be completed in a few working days. Processing times can vary depending on document completeness, for example if ownership or VAT proofs are missing.
For comparison, a UK MMSI license takes about one working day but is a separate process from UK Part 1 registration. Polish registration can take a number of weeks for the full package, while a Dutch Zeebrief MMSI can be processed as a separate application. San Marino offers a simple, bundled approach.

What Is Included in the San Marino MMSI Package?
You receive an MMSI number, an AIS number, and a call sign. These are all part of the radio license. The license covers your VHF radio, AIS, and EPIRB equipment.
The MMSI number is stored in a register maintained by the administration that issued it. There is no annual renewal fee for the MMSI itself — the license is valid for the duration of your registration. However, some flags charge an annual radio license tax. San Marino’s radio license is typically included with no additional costs.

How to Get an MMSI Number: The General Process
To get an MMSI number, you need a ship station license from your flag state. The process varies by country. Some flags issue it automatically with registration, like San Marino. Others require a separate application. You will need your vessel’s details and proof of ownership. In most yacht registries, you cannot complete full yacht registration without proving ownership. The license is usually valid for the duration of your registration. You must keep the license onboard your yacht at all times.
Is an MMSI Number Free to Get?
An MMSI number is not free. There is a cost for the radio license. BlueWater’s MMSI & AIS Radio License Service costs €350. This includes your MMSI number, AIS number, and call sign. This price is the same regardless of the flag state you choose, covering the service fee for processing the license application.
San Marino registration includes the license in the package price.
How to Get an MMSI Number in the UK?
If you are a UK resident, you can apply for a UK MMSI license. BlueWater’s MMSI & AIS Radio License Service costs €350. Processing takes one working day. You must be a UK resident for a UK Part 1 registration.
San Marino vs Other Flags: MMSI Speed and Convenience
San Marino offers the most straightforward and convenient MMSI registration because the license is included with your registration package. There is no separate application process. However, it is not necessarily the fastest option in every situation. For example, if you already have a UK Part 1 or Dutch Zeebrief registration, the separate MMSI application can be processed in 1 working day. San Marino is the simplest choice for owners who want an all-in-one solution without residency requirements.
Other flags vary. UK licenses are fast (about one working day) but require separate applications. For UK owners, UK Part 1 registration provides other benefits and a straightforward MMSI application. For Dutch residents, our Dutch Zeebrief registration offers advantages such as a separate MMSI process.

When Is San Marino MMSI the Best Choice?
San Marino MMSI registration is ideal if you are a non-EU resident, want a straightforward process without separate applications, and prefer no annual renewal fees for the license itself. It is also a strong option if you need a simple, bundled package that includes everything from day one. However, if you are a UK resident and want a UK-issued MMSI with a UK Part 1 registration, that may be more convenient for you. Similarly, Dutch residents may find the Dutch Zeebrief package more suitable. San Marino is particularly advantageous for non-EU owners who want a straightforward, all-in-one solution.
Consider these scenarios:
- Non-EU resident without a UK or Dutch address: San Marino or Polish registration are your best options, as they have no residency requirements.
- Want everything in one package: San Marino and Polish registration both include the MMSI automatically, saving you a separate application.
- Need a fast separate MMSI: If you already have a UK or Dutch registration, the separate MMSI process takes only one working day.
- Unsure about VAT status: If you cannot prove the VAT status of your yacht, customs authorities may request more documents and question whether the yacht can be used in EU waters. VAT proof may be required for full registration, but BlueWater can advise on your options.
When Is San Marino MMSI NOT Suitable?
San Marino MMSI is not suitable if you already have a yacht registered under another flag and only need an MMSI license. In that case, a separate application with your existing flag is quicker and avoids changing your registration. San Marino MMSI is designed for owners who want a complete registration package, not for those who already have a flag and just need a radio license. It is also not the best choice if you need an MMSI urgently and cannot wait the minimum 2 months for full San Marino registration.
VAT Implications for Non-EU Residents
If you are a non-EU resident, VAT status is a critical consideration. In most yacht registries, you cannot complete full yacht registration without proving ownership and, in many cases, VAT status. If you cannot prove the VAT status of your yacht, customs authorities may request further documents and question whether the yacht entered the EU without import VAT. VAT proof is exactly required when importing a yacht into the EU, during customs clearance, or when transferring ownership. Without it, authorities may question whether the yacht can be used in EU waters. BlueWater can advise on your VAT options and help you understand the requirements for your specific situation. For non-EU owners, San Marino offers a clear path, especially if your yacht’s VAT status is already established.
