Manchester United are likely to be given more than 6,000 tickets for the FA Cup fourth-round tie with Liverpool at Anfield this month.
United received a reduced allocation for October's league fixture because of fans blocking gangways at fixtures.
But Liverpool City Council has said its objections have now been lifted.
United may get the bottom tier of the Anfield Road stand, holding just under 6,400, but two seats at the end of each row, around 300, will not be sold.
"We have taken into account the improvement of the Manchester United supporters at the most recent Premier League fixture relating to the blocking of gangways and aisles," said Stephen Clare, Liverpool City Council's principal licensing officer.
"Liverpool FC will be responsible for determining the actual numbers that this will result in."
The fourth-round match takes place on the weekend of 28/29 January.
It will be the first time the teams have met since the 1-1 draw at Anfield on 15 October in which Liverpool striker Luis Suarez clashed with United's Patrice Evra.
Suarez was subsequently banned for eight matches and fined £40,000 after being found guilty of racially abusing Evra.
Additional security will be in place for the tie and it is expected the front row of the top tier of the Anfield Road stand will not be sold for the game, the first between the sides in the FA Cup at Anfield since 2006.
Suarez will still be suspended for the match, a date for which should be confirmed by the Football Association this week.
However, the Uruguay international would be available for any replay, and for the Premier League game between the teams at Old Trafford on 11 February.
