Where PA sits
It is administratively fragmented, reaching into Renfrewshire, Inverclyde, Argyll and Bute and North Ayrshire and 1 other authority.
Every PA postcode is in Scotland. Water there is regulated by the Scottish Environment Protection Agency, and Temporary Use Bans under the Water Industry Act 1991 do not apply in Scotland at all.
Water supply across PA
All 67 PA districts are supplied by Scottish Water, 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 Scottish Water's status. It was last confirmed on 17 August 2026 as no restrictions, and until it is confirmed again this page does not assert a current position for it.
The shape of the PA area
The districts are wildly uneven: PA2 holds 1,000 postcodes around Paisley and PA74 holds 1, a ratio of about 1000 to one. They divide into 102 sectors.
The numbering is not continuous. PA runs up to 80 but has only 67 districts, so 13 numbers are unused:.
Several districts share a settlement, which is a common source of confusion when a form rejects an address: PA34, PA35, PA37, PA38, PA62, PA63, PA64 and PA65 all point at Oban, PA68, PA71, PA72, PA73, PA74, PA75 and PA80 all point at Tobermory and PA5, PA6, PA9, PA10, PA11 and PA12 all point at Johnstone.
What borders PA
PA sits next to G (Glasgow) to the east, KA (Kilmarnock) to the south east, FK (Falkirk) to the east, PH (Perth) to the north east and ML (Motherwell) 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.
Download the PA 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 PA area?
There are 67 PA postcode districts, running from PA1 to PA80, and they contain 9,504 live postcodes across 102 sectors.
What towns does the PA postcode area cover?
PA covers Paisley, Johnstone, Gourock, Port Glasgow, Renfrew and Greenock. The area takes its name from Paisley, and each district is listed with its settlement in the table on this page.
Which water company supplies PA postcodes?
Scottish Water supplies all 67 PA 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 PA34 and PA35 both say Oban?
PA34, PA35, PA37, PA38, PA62, PA63, PA64 and PA65 all serve Oban, 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 PA postcode map?
Yes. This page offers the PA 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.
Which councils cover the PA postcode area?
PA reaches into Renfrewshire, Inverclyde, Argyll and Bute, North Ayrshire and Highland. 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.
Why is there no PA40 postcode district?
PA40 is not in use. Postcode districts are allocated as sorting requirements change rather than numbered straight through, and a code that is retired or never brought into service is not reissued, so gaps in the sequence are normal.
