A lot of us have had our Driver's License for a LONG time. Lots of times when renewing, the clerk just copies information off of last card you had. This may happen many times over the years. When calling in the 4473, the FFL gives information off of 4473 and your Driver's License. If you give correct up to date information on 4473 about your weight, height etc. and it differs from Driver License, that throws up a red flag on the other end. Make sure the information on the 4473 is EXACTLY the same as your Driver's License.
