Both teams have been upgraded from the bronze medal position for their performances at the 2008 Olympics in Beijing and 2012 Olympics in London due to doping sanctions handed to the silver medal-winning teams of Russia from both Games.
Last year, Great Britain & Northern Ireland were awarded their bronze medal from the 2008 final, with Ukraine also receiving medals for the 2012 race.
The team set to be awarded from the 2008 Olympic silver medals today in London are: Shereefa Lloyd, Shericka Williams, Rosemarie Whyte, Novlene Williams-Mills, Bobby-Gaye Wilkins.
The team set to be awarded the 2012 Olympic silver medals are: Christine Day, Shereefa Lloyd, Rosemarie Whyte, Shericka Williams, Novlene Williams-Mills.
Four of the six athletes were affected by the original results twice, being part of both relay teams.
Both teams are set to receive their medals on Sunday 21 July and will have them presented by Mr Pal Schmitt, Member of the International Olympic Committee and a two-time Olympic champion.
Major Events Director, Cherry Alexander OBE said:
