Excel 2007 : returning values searching with only the first 4 characters

Hi,

i am looking to return the value from a column C which is related to column B. the issue is that only the first 4 characters of the word match and column B cannot be sorted either.
for example i have;
column B Column C
FANCOTE ALBIAV
NA AMITBO
STOREY ANDERO
CUL-DE-SAC ARISPA
KENTUCKY ARMADR
BUFFER ARMALA
STOCKTON ARMARO
BUFFER AROMCR
KINSHIP AUBIGR
AROMATIC FANCAV

how can i get excel to identify the first 4 characters of the two columns and then return column C's whole word into column A (in this case FANCOTE will have FANCAV next to it in column A)
