If the cell you're validating is A1, with the current value of: abcd1234567 --------------------------------- Your first criteria is easy: Len(A1)=11 --------------------------------- The second criteria: "last 7 characters are numeric" CAN be fairly simple, depending on your definition of "numeric". right(A1,7) gives you the last 7 characters. "normallY", ISNUMBER() would tell you if the characters are numeric. But for some reason, since your cell value is alphanumeric, Excel considers the last 7 characters as "text" and therefore, ISNUMBER(RIGHT(A1,7)) would return FALSE. So, you have to convert it to an number. you can either use: INT(RIGHT(A1,7)) or RIGHT(A1,7)*1 I chose ISNUMBER(RIGHT(A2,7)*1) Now, as the to your definition of "numeric": To Excel all of these are 7 digit "numerics": 1234567 .123456 123.456 123456% If that is acceptable, than all is well and good, if NOT then we'll have to work on testing each individual character to see if it is between 0 and 9. --------------------------------- Your third criteria: "the first 4 characters as alpha" requires testing each character separately. To extract the character, you can use the MID() function MID(A1,4,1) extracts the fourth character MID(A1,3,1) extracts the third character MID(A1,2,1) extracts the second character. MID(A1,1,1) extract the first character (you COULD use LEFT(A1,1) but to keep it looking the same, I prefer to use MID()) Now, to test to see if it is alpha, use ISTEXT() Resulting in: ISTEXT(MID(A1,1,1)) --------------------------------- Now, for the validation formula, each of these criteria must be met. By combining them, you get: =AND(LEN(A1)=11, ISNUMBER(INT(RIGHT(A1,7))), ISTEXT(MID(A1,1,1)), ISTEXT(MID(A1,2,1)), ISTEXT(MID(A1,3,1)), ISTEXT(MID(A1,4,1)) )
