"Effective September 25, 2008, Publication 52, Hazardous, Restricted, and Perishable Mail, is revised to offer a new option for mailing cremated human remains to domestic addresses and to eliminate the current requirement for requesting a return receipt when the remains are sent via Registered Mail service.  Currently, the only option for mailing cremated human remains is Registered Mail service with return receipt requested.  We now also offer the option to use Express Mail service as a faster alternative for mailing cremated remains domestically.  Since verification of the date and time of delivery for both Registered Mail and Express Mail service is now available online or by telephone, there is no longer a need to require return receipt service and this requirement is now removed."
