Tickets for the concert to benefit the victims of the Manchester attack have gone on sale.
One Love Manchester takes place on Sunday, with proceeds going to the Red Cross's Manchester Emergency Fund.
Last Monday, 22 people died and 116 were injured in a suicide bombing at an Ariana Grande concert at Manchester Arena.
Grande will play at the benefit gig alongside Take That, Niall Horan, Katy Perry, Miley Cyrus and Justin Bieber.
Those who attended Grande's original concert have been offered free tickets, with other tickets on sale to the general public priced at £40.
Some concertgoers who bought their tickets for Grande's original show from secondary ticketing sites were initially told they would not be eligible for free tickets to One Love Manchester.
The Black Eyed Peas were added to the One Love Manchester line-up on Wednesday
But those websites are now making efforts to ensure that tickets are offered to the people who actually went to the original gig, rather than those who first purchased the tickets.
Ticketmaster, which owns Getmein, told the BBC: "We are doing everything possible to extend the offer to all fans we can verify were at the show."
Fans who were at last Monday's concert had until 22:00 BST on Wednesday to register for free tickets for the benefit gig.
The application included a section where fans could say they bought their original tickets from a secondary site.
The concert, held at the Emirates Old Trafford stadium, will be broadcast on BBC One and is expected to raise more than £2m for the Red Cross fund.
The Black Eyed Peas, Coldplay, Usher and Pharrell are also going to be performing.
Fans have been asked not to bring bags to avoid delays going through security.
ITV has made schedule changes to avoid the final of Britain's Got Talent clashing with the benefit gig.
