locational accuracy

[USGS Structures]

A few of the post offices I have found are on shopping centers, I
have figured out where in the centers they are either calling or
street view available online.

Should I list the shopping centers name somewhere in the data building
name, or locational attribute source or does it even matter?

Also if we use a could source should we just list the last used source
in attribute source.
For instance I found the phone number and address from US Post office
site but called to ask which part of shopping center exactly they were
in. Should I list personal Contact and put in the notes also used
authoritative website?

If you called the post office to verify the location please choose
'other' under locational accuracy and then explain in the comments
box. If you used the website to verify the attributes, such as the
address, then choose authoritative website under attribute source.
Does that answer your question?

Do not list the shopping center's name unless it is in the official
name on the USPS website. This would rarely be the case for any
feature.
