No hosepipe ban currently applies anywhere in PR.
The shape of the PR area
The districts are wildly uneven: PR4 holds 1,840 postcodes around Kirkham and PR0 holds 17, a ratio of about 108 to one. They divide into 78 sectors.
The numbering is not continuous. PR runs up to 26 but has only 13 districts, so 14 numbers are unused:.
District by district: PR0 serves Preston, PR1 serves Preston, PR2 serves Fulwood, PR3 serves Longridge, PR4 serves Kirkham, PR5 serves Bamber Bridge, PR6 serves Adlington, PR7 serves Chorley, PR8 serves Southport, PR9 serves Southport, PR11 serves Fulwood, PR25 serves Leyland and PR26 serves Leyland.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: PR0 and PR1 all point at Preston, PR2 and PR11 all point at Fulwood and PR8 and PR9 all point at Southport.

PR sits next to FY (Blackpool) to the north west, WN (Wigan) to the south east, BL (Bolton) to the south east, L (Liverpool) to the south and BB (Blackburn) to the east.

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.

Frequently asked questions
How many postcode districts are in the PR area?
There are 13 PR postcode districts, running from PR0 to PR26, and they contain 13,736 live postcodes across 78 sectors.
What towns does the PR postcode area cover?
PR covers Southport, Fulwood, Kirkham, Preston, Chorley and Longridge. The area takes its name from Southport, and each district is listed with its settlement in the table on this page.
Which water company supplies PR postcodes?
United Utilities supplies all 13 PR 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 PR0 and PR1 both say Preston?
PR0 and PR1 all serve Preston, 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 PR postcode map?
Yes. This page offers the PR 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 PR area called Preston when it covers Kirkham?
PR takes its letters from Preston, where the sorting office that served the area was based when the code was allocated. Kirkham is the largest settlement in the area today, in PR4, but the area code follows the historic sorting geography rather than current population.
Which councils cover the PR postcode area?
PR reaches into Lancashire and Sefton. 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.
