| Parameter | No of bits | Description |
|---|---|---|
| Message ID | 6 | Identifier for Message 6, always 6. |
| Repeat Indicator | 2 | Used by the repeater to indicate how many times a message has been repeated. 0 – 3 0 = default 3 = do not repeat anymore |
| Source ID | 30 | MMSI number of source station. |
| Sequence Number | 2 | 0 – 3; refer to ITU-R M.1371-3, Annex 2, § 5.3.1. |
| Destination ID | 30 | MMSI number of destination station. |
| Retransmit Flag | 1 | Retransmit flag should be set upon retransmission. 0 = no retransmission = default 1 = retransmitted |
| Spare | 1 | Not used. Set to zero. |
| IAI | 16 | DAC = 001; FI = 18 |
| Message Linkage ID | 10 | A source specific running number, unique across all binary messages equipped with Message Linkage ID. Used to link additional information to the message by a Text Description message. The Message Linkage ID and the first six digits of the source MMSI uniquely identify the sent message. 1 – 1,023 0 = not available = default |
| Clearance date/time to enter port |
UTC date and time. | |
| UTC Month | 4 | 1 – 12 0 = not available = default |
| UTC Day | 5 | 1 – 31 0 = not available = default |

| UTC Minute | 6 | 0 – 59 60 = not available = default |
| Name of port and berth | 120 | Name of the port and berth. Maximum 20 characters 6 bits ASCII as defined in ITU-R M. 1371-3, Table 44. “@@@@@@@@@@@@@@@@@@@@” = not available = default |
| Destination | 30 | UN LOCODE; 5 characters 6 bits ASCII “@@@@@” = not available = default |
| Longitude | 25 | Longitude in 1/1,000 min, ±180 degrees as per 2’s complement (East = positive, West = negative). 181 = not available = default |
| Latitude | 24 | Latitude in 1/1,000 min, ±90 degrees as per 2’s complement (North = positive, South = negative). 91 degrees = not available = default |
