# Shipping Container Generates shipping container code values that are compliant with ISO 6346. All of the generated codes are in the freight category ("U"). ## Characteristics


Consistency	Yes, can be made self-consistent or consistent with another column.
Linking	No, cannot be linked.
Differential privacy	Yes, if consistency is not enabled.
Data-free	Yes, if consistency is not enabled.
Allowed for primary keys	No
Allowed for unique columns	No
Uses format-preserving encryption (FPE)	No
Privacy ranking	1 if not consistent 4 if consistent
Generator ID (for the API)	`ShippingContainerGenerator`

## How to configure To configure the generator, toggle the **Consistency** setting to indicate whether to make the generator consistent. By default, the generator is not consistent. If you enable consistency, then by default the generator is self-consistent. To make the generator consistent with another column, from the **Consistent to** dropdown list, select the column. When the generator is self-consistent, then a given value in the source database is always mapped to the same value in the destination database. When the generator is consistent with another column, then a given value for the other column in the source database always results in the same shipping container code value in the destination database. For example, a shipping container column is consistent with an owner column. Every instance of an owner column from the source database has the same shipping container value in the destination database. If [Structural data encryption](https://docs.tonic.ai/app/generation/generators-assign-config/generators-data-encryption-config) is enabled, then to use it for this column, in the advanced options section, toggle **Use data encryption process** to the on position. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
