Supporters will be able to purchase tickets for Wednesday's friendly match at Dagenham & Redbridge from the Chigwell Construction Stadium on match night.
Terracing places are available for Hammers supporters priced at £10 adults, £8 over-65s and £3 under-16s.
The Hammers have already sold in excess of 1,600 tickets for the Chigwell Construction Stadium match, which will look to raise much-needed funds for the Daggers, who find themselves in a difficult financial situation.
David Moyes is set to take a strong West Ham squad to contest the fixture, as his team work on their match sharpness during the international break.
The manager said: “We got a letter from Dagenham asking if we could help out. It’s a football community, we all compete against each other, but I think it’s important that you help the local teams.
“With us being the biggest club in the area, it’s only right we help the ones below. Hopefully they get a full house, we’ll take a team down there in the international break and give Dagenham all the proceeds to help them keep the club, make sure the players get paid and do whatever they need to do with it.”
