Try something like this:

With your posted scenario

C2: =COUNTIF($B$2:$B$4,LEFT(A2,6))=1

Copy that formula down as far as you need

Is that something you can work with?

Ive been racking my brain trying to figure this out on my own but can't seem
to get it right. The problem that I have is I am trying to match phone
numbers in a column with a data base of the first 6 digits of the number that
I can call, and either get a true or fasle or any thing that will indicate
that I can call those numbers.

Example:
Number NPANXX Results
2813356789 281225 False
2813377896 281337 True
2815672345 281445 False
2813458765 False
2814452321 True

The results shoud be (False,True,False,False,True) in column C because the
number does not have the the first 6 digits
