Albion will be backed by a full away section in Rome as their Europa League tie heads for a total sell-out.
All 3,425 tickets have been snapped up by Seagulls fans for the first leg at the Stadio Olimpico.
In Italy, the expectation is that home areas will also sell out several days before the game.
New boss Daniele De Rossi has excitement at fever pitch in the capital and media are describing the interest in the Europa tie as “Brighton fever”.
Albion have published important travel tips and information via their website.
It includes details of shuttle buses which will take fans to and from the stadium.
Use of the buses is strongly advised by AS Roma and the Italian police.
