Answer:
When addresses appear within the text of a document it is optional to abbreviate the parts of the address
Step-by-step explanation:
There is a difference in how do we write an address in an envelope and within a text, this main difference is related to punctuation, whenever you are writing an address on an envelope you use only capital letter and don't follow some punctuation rules, all the contrary whenever you write it within a text you can use abbreviations but you have to use capital and small letter as well as commas and periods.
