How to request an ATCO Code split

Published: 08/02/2024

What is an ATCO code?

An ATCOAreaCode (ATCO code) is a number allocated to regions in England, Scotland and Wales which is used by the NaPTAN system. For example, North Yorkshire has the ATCO code 340.

An ATCO code will need to be split if a region undergoes change resulting in a new region area. The transport stops in the new region will need to be recreated with a new ATCO code and removed from the current system.

These stops are not just no longer active, they cannot ever be recreated with their current ATCO code.

Northamptonshire split into 300 and 305

What do you need to know?

Northamptonshire (ATCOAreaCode 300) has been split into two – West Northamptonshire (300) and North Northamptonshire (305). The NaPTAN codes for North Northamptonshire bus stops have also changed.

What do you need to do?

Download the latest version of both NPTG and the National NaPTAN data or the 305 NaPTAN data.

This will update your system with the new stops.
