What is also commonly called the mini-Miranda pursuant to 15 U.S.C. 1692e(11)?

When an individual or company fails to pay what is due, the usual procedure is for several reminder letters to be sent (and ignored or without payment) before more serious action is taken. In the last stage, a debt collector must be used. He must act according to established principled and this includes the actual words he uses when attempting to recover the debt.

Firstly, of course, he must establish that he is talking to the individual who has incurred the debt. Then he must used these exact words "This is an attempt to collect a debt and any information obtained will be used for that purpose."
