Letter Writing - FULL Format - Situation 3 - from an organisation to a private individual

SITUATION 3

Let us pretend that you are writing for your organisation to a private individual. If you are doing so, then you must KNOW the name of that recipient.  It will be a ridiculous situation if you did not. 

So the full format should be:

12  Mary Road
Singapore 123456

11 July 2010

Ali bin Ahmad [Name of your recipient - private individual/no position]
Block 123  Bedok North Street 6
#03-123
Singapore 678910
