MySQL. In what types of data and how should I store these keys?

There are the following keys:
The first(comma-separated):WB-0502/0000173, 248, 10206/100026, 10210/110312/10115/3
The second(separated by commas):10206090, 103F2F20, 1031300H, 10505000
In what types of data they store?

numeric letter will not retain
but generally the task is not solved
to put before each key number, and to do it with a key, this option does not suit me too. - Gabrielle73 commented on July 2nd 19 at 13:31
