Water supply across NG
All 31 NG districts are supplied by Severn Trent, which is notable at this size: an area with this many districts usually crosses at least one supply boundary, and this one does not.
We are re-checking Severn Trent's status. It was last confirmed on 18 August 2026 as voluntary appeal, and until it is confirmed again this page does not assert a current position for it.
The shape of the NG area
The districts are wildly uneven: NG5 holds 1,928 postcodes around Arnold and NG90 holds 19, a ratio of about 101 to one. They divide into 170 sectors.
No single district dominates: the largest holds only about 6 per cent of the area's postcodes.
The numbering is not continuous. NG runs up to 90 but has only 31 districts, so 59 numbers are unused:.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: NG8, NG9, NG11, NG80 and NG90 all point at Beeston, NG1, NG3 and NG7 all point at Nottingham and NG4, NG5 and NG14 all point at Arnold.
What borders NG
NG sits next to DE (Derby) to the west, LE (Leicester) to the south, S (Sheffield) to the north west, LN (Lincoln) to the north east and DN (Doncaster) to the north.
Its neighbours run in 5 different directions, so NG is landlocked by other postcode areas on most sides.

Hardness is published per census area, not per postcode, so these figures characterise a district rather than measuring one address. They are a scale and taste matter, not a safety one. Hardness data version wessex-water@2022-2025+yorkshire-water@2026.
Download the NG data
No signup, no email wall. GeoJSON carries the district points, the supplier and the live status, so it can be dropped straight into a map.
District positions are averaged postcode centroids from OS Code-Point Open. They show roughly where a district sits, not where its boundary runs, and are not legal boundaries.
Frequently asked questions
How many postcode districts are in the NG area?
There are 31 NG postcode districts, running from NG1 to NG90, and they contain 29,864 live postcodes across 170 sectors.
What towns does the NG postcode area cover?
NG covers Beeston, Arnold, Nottingham, Grantham, Newark-on-Trent and Mansfield. The area takes its name from Beeston, and each district is listed with its settlement in the table on this page.
Which water company supplies NG postcodes?
Severn Trent supplies all 31 NG districts. Supply boundaries follow the pipe network rather than postcode geography, so confirm against your water bill if you are near the edge of the area.
Why do NG8 and NG9 both say Beeston?
NG8, NG9, NG11, NG80 and NG90 all serve Beeston, covering different parts of it. A single town routinely needs more than one postcode district once it passes a few thousand delivery points, so this is normal rather than an error in an address.
Can I download a free NG postcode map?
Yes. This page offers the NG districts as GeoJSON, CSV and SVG, free and with no signup or email address required. The GeoJSON carries each district's position, its water company and its current restriction status, so it can be dropped straight into a mapping tool.
Why is the NG area called Nottingham when it covers Arnold?
NG takes its letters from Nottingham, where the sorting office that served the area was based when the code was allocated. Arnold is the largest settlement in the area today, in NG5, but the area code follows the historic sorting geography rather than current population.
Which councils cover the NG postcode area?
NG reaches into Nottinghamshire, City of Nottingham, Derbyshire, Lincolnshire and Leicestershire. A postcode area is not a council area: they were drawn for different purposes and a single district can sit across a council boundary, so your postcode does not tell you which authority you pay.
