BT stopped fulfilling orders for VeriSign Server Certificates on 26 September 2004 and is now passing these to VeriSign for processing. As a result, BT no longer operates the Registration Authority service that was approved by tScheme, although it will continue to support customers who purchased certificates prior to this date until their certificates expire or are revoked.
