Design decision: Convert code to display String

I'm developing a project with domain objects that contains quite a few fields. The fields only store numbers as codes or IDs.

To display these domain objects, I have to write some logic to convert the codes to display labels.

Now, with my most straightforward thoughts, I'd just write a utility class to do the conversion.

However, since this should be a very common cases, I am just wondering is there any better practice for doing this kind of job? (in a more object-oriented way)

Is there any design pattens for this context?

Thank you so much!
