The 17-year-old received support from Dortmund and the Football Association after sharing images of the racist messages he received on Instagram.
The post showed a number of comments on an earlier post which were highlighted by Bellingham, including monkey and faeces emojis, as well as a derogatory message about the player’s mother.
The former Birmingham youngster posted the replies with a short message which read: “Just another day on social media…”
Bellingham made his England debut in November, becoming the third-youngest senior Three Lions international in the process.
He was also included in Gareth Southgate’s squad last week for the upcoming World Cup qualifiers triple-header next week.
England tweeted: “We continue to be disgusted by the discriminatory abuse our players – and others across the game – are being subjected to online. Something needs to change. We stand with you, BellinghamJude.
Dortmund – who signed the midfielder in July 2020 – retweeted the post and offered their support to Bellingham.
“We stand with you BellinghamJude. Racism belongs nowhere £BorussiaVerdindet,” they wrote.
Bellingham may not yet be able to link up with England when the squad assemble at St George’s Park at the start of next week.
Regional Covid-19 regulations in Germany may prevent him joining up for the World Cup qualifiers against San Marino, Albania and Poland.
Asked if he knew what part Bellingham could play this month, Southgate said last week: “We don’t know. We’ve left him in the squad. At this moment in time it looks as though we won’t be able to take him.
“The quarantine rules in Germany looked like they’ll rule him out.
“But, as we’re seeing, those rules can change so quickly and while we’re still investigating what’s possible we wanted to name him in the squad.
“We’ve got a really good relationship with Dortmund so no issues between us and the club.”
