South Humberside, Postal county in eastern England, United Kingdom
South Humberside is a postal county in eastern England covering the southern shore of the Humber estuary, and it takes in towns such as Grimsby, Cleethorpes, and Scunthorpe. Most addresses in this area use the DN postcode prefix, which applies across a broad stretch of the region.
The postal county was created in 1974 when English administrative boundaries were reorganized on a large scale, and the name matched the new administrative county of Humberside that was formed at the same time. The postal designation outlasted the administrative one, remaining in use even after the region was divided.
The fishing and port trades have left a clear mark on the towns of South Humberside, and their traces are easy to spot in the streets and harbors today. Grimsby in particular still has a working waterfront where the daily routines of dock and fish trade workers give the area a distinctive character.
When sending mail to this area, using the correct postcode and post town is the most important step, as South Humberside is still a recognized postal address within the Royal Mail system. Checking the full address on the Royal Mail website before sending helps avoid any delivery issues.
South Humberside continues to appear on official Royal Mail address lists even though it no longer exists as an administrative region, making it one of a handful of postal counties that outlived their administrative counterparts. A letter addressed to South Humberside today is routed through a system that treats the name as fully current, decades after local government stopped using it.
