How should you address someone with OBE following their name?

When addressing someone with an OBE (Order of the British Empire) following their name, you should use the title "Mr.", "Mrs.", "Ms.", or "Dr." as appropriate, followed by their name. For example, you would say "Mr. John Smith, OBE." In formal writing, you can also include the OBE after their name at the end of the sentence or in a list of credentials. It's important to respect their title and use it appropriately in both spoken and written communication.
