How to fill a column with specific data in a flow.

Question

What is the best practice/way for filling in a column with a specific  string (area telephone code) which is different each time the flow is run? That is, each time a workflow is run, I need to fill a column (Area Code) with an area code I will manually need to check/input each time?

Here's 2 ways of doing it.  One being an app where you enter the Area Code and it automatically updates a formula.  The other being the same thing just without the interface and you would have to manually update the formula with your Area Code each run.
