I have been looking into implementing the FGDC street address data standards so that my address data is potentially consistent with other US data I obtain in the future. However, the FGDC documentation doesn't suggest actual names to name the fields.

I currently am using the following fields:

555 1 SW Main St, Ste B

 - ST_NUMBR:  555
 - ST_NSFX:   1
 - ST_NAME:   Main
 - ST_TYPE:   ST
 - ST_UNIT:   Ste B

To be consistent, I should probably change the ST_PREFIX field to ST_PREDIR, but if I'm making changes I might as well know if there are other conventions I should be following.

Are there any standard or common names for such address fields?
