Washington: The US Treasury Department has ordered President Donald Trump's name to be printed on cheques the Internal Revenue Service is planning to send to tens of millions of Americans, a decision that will slow their delivery by several days, the Washington Post reported.

Citing unnamed administration officials, the Post said the $US1200 ($1870) cheques to be sent as part of a $US2.3 trillion package enacted last month to cushion the economic blow from the coronavirus outbreak will "bear Trump's name in the memo line, below a line that reads, 'Economic Impact Payment'."

The White House and the Treasury Department did not immediately respond to Reuters requests for comment.

The Post said the decision to include Trump's name was announced to the IRS information technology team on Tuesday, US time (Wednesday AEST).
