Salisbury supporters are expected to be housed in half of the Len Weston stand where the two clubs meet in the FA Vase on March 12th.
This will mean that they will have an allocation of around 600.
As regards the game at Salisbury on March 19th, much will depend on how the home club decides to segregate the supporters.
But the initial thinking is that Hereford will be offered an allocation of around 500.
Whatever is decided Hereford supporters are being urged to keep their ticket stubs if attending tomorrow evening's game against Highgate.
The club shop will open at 10am for ticket sales. Tickets can also be purchased online.
