# PIS

*PIS code lookup is supported for GWR and HEx services*

There are two ways for you to find PIS codes; using the timetable search on the homepage, and using the PIS Finder page.

## Timetable Search

By typing a headcode into the timetable search, you are more likely to find a match.  Partial matches are returned through the timetable search - where you need to skip stops the number of stops to skip will be specified.

To find out how to use the timetable search, see the [timetable guide](timetable.md).

## PIS Finder

As an alternative to the Timetable Search, you can use the PIS Finder.  Here, you simply enter the CRS code of the start and end station to see matches.  You can also search for a PIS code by number to see which stops it contains.

All PIS codes that match the start and end locations are returned (Duplicate stopping patterns do exist):

You can check the results to find a code that contains the stops you need.

Some routes contain a large number of codes which may make finding a suitable code difficult.  It is recommended that you use the [timetable search](timetable.md) instead.
