To fill attributes with an specific format

I don’t know if there is a possibility to create an attribute with an specific format.

For example, the Social Security number has this format 28/0000000/1.

This is a mandatory field for each employee, but each one write it in a different way (2800000001, 28-0000000-1 and also 28 0000000 1).

I would like to have this field with only one format to write, in order to have the same data when I download an employee report: only numbers but without dots, like this 2800000001.

I’m not able to find any article related to this topic.

Thanks in advance
