A separate version exists for Scotland, bearing the Scottish Crown.
The image will be seen on letters from Government departments and on some postboxes.
The design was picked personally by the sovereign out of a collection presented by the College of Arms.

He was “instrumental in setting up the Court Post Offices in Buckingham Palace”, the account posted.
It continued: “The cypher was introduced at a time when the Monarch was seen by very few people, to create identity.”
This coincides with the announcement by Royal Mail that four new stamps marking the Queen’s reign will be made available to the public later this year.
The stamps will take the form of portraits of the Queen, and have been approved by the King.
The Queen’s cypher will still appear in many places as Charles’ is phased in
The portraits were taken in 1952, 1968, 1984 and 1996.
They were approved by the Queen to mark her Golden Jubilee back in 2002.
The postal service has also said that stamps featuring the new sovereign will “enter circulation once current stocks of stamps are exhausted”.
The portrait that is to appear on the notes will be unveiled later this year.
The Royal Mint has also said new coins will become available “in line with demand from banks and post offices”.
But all coins and notes bearing the face of Queen Elizabeth II will still be valid as legal tender.
