Due to it lacking a community, a market, or any major important centre, South Lynn was merged into King's Lynn in 1555 and since then, has formed a major part of the southern part of the town.

The civil parish was abolished on 1 April 1935 to form Kings Lynn.

[9] The area is served by bus routes 46, 47 and X46, which provide services to King's Lynn, Downham Market and Wisbech; the routes are operated by Lynx or Go To Town (West Norfolk Community Transport Project).

South Lynn's nearest railway stations are King's Lynn and Watlington; both stations are on the Fen line, providing regular services to Ely, Cambridge and London King's Cross.

There was a short spur to connect the line to the nearby King's Lynn railway station.
