Short form of state name

Can we use short cut of state in product label or we have to write full state name?
We have different MRP for different state. So we cannot print full state name on label by inkjet printer. Karnataka as KTK
Is there any provision to add short cut of state on label or carton?
Pls give suggestions.

I think KTK is not an official short name of Karnataka state approved by Indian Government. Use of KTA can be questioned by FDA.

Can we use it sir?..
