Couriers are generic NPCs who will occasionally approach you to deliver messages. These messages sometimes serve to initiate a quest (miscellaneous or regular) and sometimes play a role in advancing a currently activated quest forward. A courier can appear anywhere in the province of Skyrim, as well as on Solstheim.
Using a dragon shout in public view can increase the probability of a contact with a courier; after doing so, he will usually appear some time later with a letter that activates a miscellaneous quest directing you to a location where they may find an undiscovered word wall. He will also occasionally bring other kinds of messages, such as a letter of inheritance.
When randomly encountered, perhaps walking along a road, you can pickpocket the courier for a courier's letter. These refer to semi-random locations and have no quest objectives connected to them. They will update your map if you have not been to the location mentioned.
