Let me tell you something to ease your tension.
I am working in field in Canada where people have to remit cheque's/draft payable to Receiver General for Canada, but sometimes they are not aware of what name to write when they are addressing payment to Government of Canada so they use below names:
-- Receiver General for Canada
-- The Receiver General for Canada
-- Receiver General of Canada
-- The Receiver General of Canada
-- Receiver General
-- Government of Canada
-- Receiver General Canada
-- The Receiver General Canada
Every name above works. I have got PE with it. So I see no reason to panic.
