However If you do not want to do some calculations with it, then use the data type as varchar (in Laravel migration: it is string) as the data type of the field. So, when it comes to storing Phone numbers, you definitely use the varchar data type as you do not have to do calculations with Phone numbers.
Phone numbers are made of numbers. Using varchar allows user to store any type of formatting, with ( or not, with - or . and it quickly creates a mess with your data. A phone # format is country dependent, the mask should be tied to the country.
