    From 1 June 2017, the ISBN agency in Suriname is no longer being operated by VACO Publishers/ Interfund Group.

    Following the International ISBN Agency's discussions with VACO Publishers/ Interfund Group, it has been agreed that they would cease to act as the ISBN agency for Suriname. This means that they will no longer provide ISBNs to publishers based there. For the present time, any publishers based in Suriname should contact the International ISBN Agency directly for all ISBN requirements. Our details are:
