In a cell, I have zip+4 format, but this does not &nbsp;prevent erroneous entries. &nbsp;I need code to insure 5 numbers, hyphen, four numbers, ie #####-####. &nbsp;Other charfacters and too many numbers or not enough numbers should bring up an error with a retry or cancel. &nbsp; Would the zip+4 formatting still be required? &nbsp; Please be thorough in your answer. &nbsp;Thanks in advance for your kind help! &nbsp;rgds/ron
