Overview
The RG postcode area is a group of postal districts in southern England, primarily centered on Reading, a major town in Berkshire. It extends into parts of neighboring counties, including Oxfordshire, Hampshire, and Buckinghamshire, serving both urban and rural communities. The system helps Royal Mail efficiently sort and deliver mail across a diverse geographic region.
Established in the late 1950s, the RG postcode has evolved to accommodate population growth and urban development. Today, it plays a crucial role in navigation, logistics, and digital services such as online shopping and emergency response. The area includes 20 postcode districts, each serving specific towns and neighborhoods.
- RG1 covers Reading city center and is the most densely populated district, handling over 25,000 addresses annually.

- RG6 covers Calcot and Southcote, bordering West Berkshire and experiencing rapid residential development since 2000.
- RG17 refers to Newbury, a key market town located about 25 miles west of Reading, with strong transport links to London.
How It Works
The RG postcode system functions as part of the UK’s national postal coding structure, enabling accurate mail delivery and geographic identification. Each postcode district is further divided into smaller sectors for precision.
- Postcode District: Each RG code (e.g., RG1, RG2) represents a specific geographic zone, typically centered on a major town or suburb. These districts are managed by Royal Mail’s Reading Mail Centre.
- Postal Town: The primary postal town for most RG codes is Reading, though some, like RG17 (Newbury), serve other major towns.
- Delivery Office: The Reading Delivery Office handles over 1.2 million items weekly, sorting mail for all RG districts using automated systems.
- Geographic Reach: The RG area spans approximately 600 square miles, extending as far as Farnham (RG29) in Hampshire and Watlington (RG9) in Oxfordshire.
- Population Served: An estimated 500,000 people live within the RG postcode area, including residents of Reading, Basingstoke, and Newbury.
- Historical Development: The RG code was introduced in 1959, replacing older postal regions and aligning with national standardization efforts by the General Post Office.
