Give this a try:
Code:
awk 'FNR==NR {zip[$1]; next} $NF in zip' file1 file2

Code:
FNR==NR # this condition is true only for the first file
{zip[$1]; next} # record the zips from file1 only
$NF in zip # if the zip, (last column) in file2, is found in the records, display

Output:
Code:
ID                 Name            City                 ZipCode
12343     Washington             DC                   20878
54211        Maryland           Silver Spring         20304
54877       Missouri              St. Louis             10023
