Frequently Asked Questions About UK Postcodes

Common UK Postcode Questions

What’s my postcode?

To find your current postcode, simply click the “What’s My Postcode?” button at the top of this page. Our tool will instantly show your UK postcode based on your location. Alternatively, you can click anywhere on the map to check postcodes across the United Kingdom.

How do UK postcodes work?

UK postcodes consist of two parts separated by a space:

• The outward code (e.g., “SW1A”) identifies the postcode area and district
• The inward code (e.g., “1AA”) identifies a street or group of addresses
  For example, in the postcode “SW1A 1AA”:
• “SW” is the area
• “1A” is the district
• “1AA” specifies the exact location

Why isn’t my postcode showing correctly?

This could happen for several reasons:

• Your device’s location services are turned off
• You’re using a VPN that changes your location
• You’re in a new development not yet added to the database
  Try clicking directly on your location on the map for the most accurate results.

How accurate is this postcode checker?

Our UK postcode finder uses the latest OpenStreetMap data, which is regularly updated. For most locations in the UK, you’ll get precise postcode information. However, very new developments might take some time to appear in the database.

Can I find postcodes for a specific street?

Yes! Simply zoom into the street on our map and click anywhere along it. You’ll see the postcode along with the full address details for that specific location.

Are UK postal codes and postcodes the same thing?

Yes, “postcode” is the official term used in the UK, while “postal code” is used in many other countries. They serve the same purpose – helping deliver mail to the correct address.

How often do UK postcodes change?

While postcodes generally remain stable, changes can occur when:

• New developments are built
• Areas are redeveloped
• Royal Mail updates its delivery routes
  Our tool updates regularly to reflect these changes.

Can I find a postcode without a street address?

Yes! Our map-based tool lets you find postcodes by simply clicking on any location in the UK, even if you don’t know the street address.

How do I format a UK postcode correctly?

UK postcodes should always be written with:

• Capital letters
• A single space between outward and inward codes
• No other spaces or punctuation
  Example: “SW1A 1AA” (correct) vs “sw1a1aa” (incorrect)

Can I find old or historical postcodes?

Our tool shows current, active postcodes. For historical postcode information, you may need to contact Royal Mail directly.

Do postcodes identify exact addresses?

A single postcode typically covers:

• About 15 addresses in urban areas
• Larger areas in rural locations
  For exact address identification, you’ll need both the postcode and property number/name.

What area does a postcode cover?

Postcode coverage varies:

• Urban postcodes might cover just one building or part of a street
• Rural postcodes might cover several square miles
  Click different locations on our map to see how postcodes change across an area.
