How do you compare results of vlookups not the formula themselves

I am having issues comparing the results of two vlookups. I'm looking up information based on a position from two different systems where we use the same name convention.

Sheet1 has a phone number in 2 blocks, area code and then phone number.

Sheet2 is from our cell phone provider

I am trying to compare the results of 2 separate vlookups.

Vlookup1 Cell B2
"=CONCATENATE(VLOOKUP(A2,Sheet1!A2:C3,2,FALSE),VLOOKUP(A2,Sheet1!A2:C3,3,FALSE))"

Vlookup2 Cell C2
"=VLOOKUP(A2,Sheet2!A2:B3,2,FALSE)"

The lookups report the phone numbers back correctly but I can't see to compare the results. To test this I'm using a simple IF, but ultimately will be conditionally formatting and nesting into other formulas.
=IF(B2=C2,TRUE,FALSE)

The issue is that you are comparing numeric value against text.
Column B is text value and will not equal numeric values in Column C.

You can use following:
=IF(B2=TEXT(C2,"@"),TRUE,FALSE)

EDIT: If using in CF, all you'd need is =B2=TEXT(C2,"@")
