Where CV sits
It is administratively fragmented, reaching into Warwickshire, Coventry, Worcestershire and Solihull and 2 other authorities.
Water supply across CV
All 24 CV districts are supplied by Severn Trent. That makes CV simple in a way many areas are not: one company, one set of rules, one status to check.
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 CV area
CV37 is the largest district with 1,600 postcodes around Stratford-upon-Avon, and CV33 the smallest with 348. The area divides into 111 postcode sectors.
The numbering is not continuous. CV runs up to 47 but has only 24 districts, so 23 numbers are unused:.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: CV1, CV2, CV3, CV4, CV5, CV6 and CV7 all point at Coventry, CV21, CV22 and CV23 all point at Rugby and CV10 and CV11 all point at Nuneaton.
What borders CV
CV sits next to B (Birmingham) to the west, NN (Northampton) to the east, LE (Leicester) to the north east, WS (Walsall) to the north west and WR (Worcester) to the west.
Its neighbours run in 4 different directions, so CV 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 CV 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 CV area?
There are 24 CV postcode districts, running from CV1 to CV47, and they contain 21,267 live postcodes across 111 sectors.
What towns does the CV postcode area cover?
CV covers Coventry, Rugby, Nuneaton, Warwick, Stratford-upon-Avon and Whitnash. The area takes its name from Coventry, and each district is listed with its settlement in the table on this page.
Which water company supplies CV postcodes?
Severn Trent supplies all 24 CV 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 CV1 and CV2 both say Coventry?
CV1, CV2, CV3, CV4, CV5, CV6 and CV7 all serve Coventry, 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 CV postcode map?
Yes. This page offers the CV 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 CV area called Coventry when it covers Stratford-upon-Avon?
CV takes its letters from Coventry, where the sorting office that served the area was based when the code was allocated. Stratford-upon-Avon is the largest settlement in the area today, in CV37, but the area code follows the historic sorting geography rather than current population.
Which councils cover the CV postcode area?
CV reaches into Warwickshire, Coventry, Worcestershire, Solihull, Leicestershire and West Northamptonshire. 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.
