Town haven’t taken on the Exiles at Kenilworth Road since September 2017, when Danny Hylton scored twice and Alan Sheehan was on target in a 3-1 victory as Town went on to win promotion from the fourth tier.
County finished 11th in League Two last term, with a fine away record, picking up 10 victories on the road under manager James Rowberry, who has been in charge since Michael Flynn left the club in September 2021.
The Welsh side still have former Hatter Robbie Willmott in their ranks, the 32-year-old having made over 200 appearances over two spells at Rodney Parade, returning to the club for his second stint in July 2017.
The tie is scheduled to take place the week commencing Monday, August 8.
