The Danish government decided on Tuesday to extend temporary control over the country's border to Germany by 10 days to March 4, the Ministry for Immigration, Integration and Housing said.
"The government still sees the control as necessary to avoid accumulation of illegal immigrants in Denmark," it said in a statement.
Previously, the Danish government put a 10 day border control into effect, after a similar action was taken by Sweden.
Denmark received 21,000 asylum applications in 2015, putting it far behind the 163,000 registered in neighbouring Sweden.
More than 190,000 refugees crossed the German-Danish border last year. About 13,000 applied for asylum in Denmark, while others travelled further north to Sweden, Norway and Finland, according to Prime Minister Lars Loekke Rasmussen.
