Uefa has fined the Football Association of Wales (FAW) £3,960 (5,000 euros) for the pitch invasion following Gareth Bale's late winner against Andorra last month.
The Andorran Football Federation has also been fined £7,920 (10,000 euros) for insufficient organisation inside the Estadi Nacional on 9 September.
Chris Coleman's side won 2-1 and are top of Group B after three games.
Wales' next game is away to Belgium on Sunday, 16 November.
The FAW has accepted the decision by Uefa, European football's governing body, after it was charged with a breach of article 16.2 (field invasion by supporters).
Under article six of Uefa's disciplinary regulations, there are a wide-range of possible punishments for a pitch invasion, including a warning, a fine and a points deduction.
Andorra were charged for breaches of articles 15.4 (improper conduct of the team) and 16.1 (organisation) of its disciplinary regulations.
Crowd problems broke out after the 81st-minute strike from Bale completed a Welsh turnaround.
The visitors went behind when Ildefons Lima converted a sixth minute penalty - Andorra's first goal in a competitive fixture since 2010.
A first-half header from Bale brought Chris Coleman's side level before he completed his brace after substitute George Williams was fouled 25 yards from goal.
The match was played on a 3G pitch, which Bale described as "the worst I have ever played on".
The artificial surface at Andorra's new national stadium had only been deemed suitable to stage the opening match of the Euro 2016 qualifying campaign six days earlier.
