Boston post office is established.

[3/12/1638-Thwing] General Court declares “Richard Fairbanks his house in Boston is the place appointed for all letters which are brought from beyond the seas, or are to bee sent thither.” The first post office in the British Colonies, it operates from Fairbanks’ Blue Anchor Tavern at today’s 266 Washington Street. It handles only overseas mail; those wishing to send or receive mail within the Colonies must make arrangements with private travelers until 1677.* The post office subsequently moves to the Town House, Cornhill, Milk Street, back to Cornhill, to the corner of Congress Street and Water Street in 1829, to the Town House again in 1838, to the Merchants Exchange Building in 1844, and to corner of Summer and Chauncy Streets from 1859 to 1873.*
