The SE (South Eastern) postcode area covers a broad area of the south and south-east of the London, England post town from the Albert Embankment to West Heath and the nearest edges of Sidcup and Selhurst. It loosely corresponds to the boroughs of Southwark, Lewisham and Greenwich plus indicated parts of the boroughs of Croydon (north), Lambeth (east), Bexley (west) and Bromley (northwest).

Postal administration

The postcode area originated in 1857 as the SE district. In 1868 it gained some of the area of the short-lived S district, with the rest going to SW. It was divided into numbered districts in 1917, by giving the district closest to London that hosted the head office the suffix "1" and all others alphabetically based on a locally important parish, chapelry, topological or built environment feature administering or close to the local distribution office. SE28 is a late addition carved out of the existing districts SE2 and SE18 to reflect the building up of a new London district in what had been the meadows and marshes by the tidal Thames in the parish of Plumstead: Thamesmead.

Unlike SW, where a consecutive 50%, there ten, districts can more officially be traced into two alphabetical groups excluding SW1, SE has always technically followed the norm in that SE1 is the only head district. However SE19 was drawn up to serve the key distribution office serving Norwood after a complete alphabetical series so that those surrounding it and SE21 (Dulwich): SE20 and SE22 to SE27 are strictly alphabetical afresh (Anerley to West Norwood) but it has never technically been a "head district". The postcode area is part of the London post town. There are no dependent localities used in the postcode area. SE1P is a non-geographic postcode district for PO boxes located in SE1.
