The following language is often referred to as the Fair Debt Collection Practices Act Validation Notice.
THIS IS AN ATTEMPT TO COLLECT A DEBT AND ANY INFORMATION OBTAINED WILL BE USED FOR THAT PURPOSE. Unless you contest the validity of this indebtedness in writing, I will assume that the debt is valid.
The FDCPA applies only to those who regularly engage in the business of collecting debts for others -- primarily to collection agencies. The Act does not apply when a creditor attempts to collect debts owed to it by directly contacting the debtors.
