what state do social security numbers start with 455
Such numbers were issued in Connecticut.
There is no specific state that corresponds to a Social Security number starting with 147. The first three digits of a Social Security number indicate the location where it was issued, but they do not correspond to a specific state. Social Security numbers are issued by the Social Security Administration (SSA) and are not tied to a particular geographic location.
The State identifier depends on what span of years the number was issued. Typically, the State Identifier is where the person lived at the time (the specific date) when the Social Security Number was issued. The Social Security Administration can tell you about your SS Number, if you cannot remember what State you lived in when you (or your parents) originally applied for your Social Security number.
