The Indian Continuous Discharge Certificate–cum–Seafarer’s (CDC) is the primary identity and sea-service record for seafarers in India to sail in ships. It is required for joining a ship as a seafarer and is used by maritime authorities, employers and port/immigration officials. Before you can apply for a CDC or attend most DG Shipping–approved courses, you must first obtain an Indian National Database of Seafarers (INDoS) number which is provided by DG Shipping authority— the national e-registry that prevents use of fraudulent certificates and helps streamline seafarer verification.

Why CDC?

• The CDC is proof of your identity and sea service and is mandatory for employment on Indian-flag and many foreign-flag ships. It also serves as an official document for embarkation / disembarkation and statutory checks.
• You cannot be issued a CDC unless you hold the required STCW certificates and meet medical and regulatory requirements.

Who needs it?

• All aspiring Indian seafarers who intend to serve on merchant ships.
• Candidates completing DG Shipping–approved pre-sea or modular courses who plan to apply for sea-going employment.
• Note: Some short courses may admit candidates without a CDC but most STCW and competency pathways require INDoS + CDC later in the process.

Which course must you complete to get CDC?

To become eligible to apply for a CDC you must complete the DG Shipping–approved BST (Basic STCW Training) and STSDSD (Security Training for Seafarers with Designated Security Duties) programme. The BST which includes the following modules (all DG Shipping approved):

• PST – Personal Survival Techniques
• FPFF – Fire Prevention and Fire Fighting
• EFA – Elementary First Aid
• PSSR – Personal Safety and Social Responsibility

Once you successfully complete these STCW modules and meet other DGS requirements (including medical fitness), you become eligible to apply for the CDC.

Why INDoS?

Indian National Database of Seafarers (INDoS) is a centralized electronic registry maintained by the Directorate General of Shipping. It stores verified identity details of seafarers (name, passport, photograph, signature, qualifications, etc.) and issues a unique INDoS number. This INDoS number is mandatory for admission to all DG Shipping–approved courses and for later CDC processing. Institutes (MTIs) can also help generate INDoS numbers for trainees they admit.

Why it matters?

• Prevents fraudulent claims and forged certificates.
• Reduces the need to carry original certificates for every course (originals are still required at verification).
• Speeds verification for employers and licensing authorities.

How to apply for INDoS Number?

Important Notes / Compliance

• Timeline: INDoS number issuance and admin verification timelines can vary — having perfect documents and following HIMT’s stepwise guidance reduces delays. (HIMT will confirm expected timelines at the counter.)
• Tips:
  • Double-check that name spelling and DOB match your passport on every document.
  • Carry all your originals.
  • Use a recent high-quality passport photo as per DGS specs — low quality images often cause rejection.
  • Keep payment receipts or any reference/confirmation pages.
• HIMT will only generate an INDoS for candidates who intend to take admission at the same MTI and who are physically present with originals, as per DGS/MTI rules. MTIs are responsible for secure handling of login credentials and the integrity of the application process.
• After INDoS verification, and upon completion of BST, & STSDSD Course, you will be eligible to apply for the CDC. The CDC is normally dispatched to the applicant’s residential address by the appropriate Shipping Office once issued.

FAQs

1. How do I apply for an INDoS number through DG Shipping?

To apply for an INDoS number, candidates must visit a DG Shipping–approved Maritime Training Institute such as HIMT with their original passport, 10th marksheet, photograph, and signature. The institute will assist in generating the Reference Number and completing the online application as per DG Shipping norms.

2. Is an INDoS number mandatory for joining Basic STCW courses?

Yes. A DG Shipping–approved INDoS number is mandatory for enrolling in most Basic STCW (BST) courses like PST, FPFF, EFA, PSSR, and STSDSD. Without an INDoS number, candidates cannot proceed with admission or appear for these mandatory seafarer training programs.

3. What is the difference between INDoS and CDC?

INDoS is a unique identification number stored in the Indian National Database of Seafarers, used for verifying a seafarer’s identity and certificates. The CDC (Continuous Discharge Certificate) is an official seafarer identity and service record book required for joining a ship. INDoS comes before, while CDC comes after completing the required STCW courses.

4. How long does it take to get an INDoS number?

The INDoS processing time depends on the accuracy of your documents and DG Shipping verification. The process is generally quick, and your INDoS can be instantly generated if all documents are correct.

5. Can I apply for a CDC without an INDoS number?

No, you cannot apply for a CDC without an INDoS number. INDoS is the first step, followed by completing the Basic STCW and STSDSD courses, after which candidates become eligible to apply for the Indian CDC.

6. What is the fee for INDoS and how do I pay it?

The INDoS fee is charged as per DG Shipping norms and must be paid directly on the DG Shipping portal. Candidates can pay using debit/credit card, or net banking.
