All eviction notice forms are not the same. It really does matter in what state or jurisdiction the rental property is located.
Some states require 7 days notice to the tenant for failure to pay rent. Many require 3 days notice. Some none.
Even within a state local county or city landlord-tenant law may change the eviction notice form requirements. For example, in Seattle just cause eviction ordinances must be complied with and arguably change the eviction notice form requirements. In Tennessee, an eviction notice may be a prerequisite to bringing an eviction in some metropolitan areas, but not in a more rural county.
When in doubt consult a landlord-tenant attorney in your area.
