NaPTAN guide for data managers

Updated 3 February 2023

NaPTAN stop point naming

NaPTAN 2 Field	Content (See the simple guide for information on permitted characters)	Notes
AtcoCode	The first 3 numbers denotes the authority responsible for the stop. The fourth character is a 0 (zero). The remaining characters to a maximum of 8 are alpha-numeric determined locally.
NaptanCode	A unique 7 or 8 character code suitable for displaying on stops and in public facing systems. The code is suitable for use in stops and in public facing system. Must follow detailed rules.	See NaPTAN Schema Guide for detailed rules.
CommonName	The aim is to have a unique name for an obvious group of stops within a locality. Acceptable: nearby landmark, nearby side street, the street on which the stop is located (for very short streets only where there is one group of stops). Unacceptable: a composite of 2 street names or a street name and a landmark.	The ‘obvious group of stops’ is a StopArea. The Simple Guide provides information on how StopAreas are constructed. When combined with the Indicator, the stop name should be one that the public would recognise.
Landmark	Optional field. See Simple Guide for details of how and when this field is used.	Is a candidate for use as CommonName
Street	The street on which the stop is located.
Crossing	Optional field: See Simple Guide for details of how and when this field is used.	Is a candidate for use as CommonName
Indicator	A very short way of distinguishing between 2 or more stops that have the same CommonName. Acceptable: o/s [outside], opp [opposite], adj [adjacent], Bay 1, Stance B, stop 5. Unacceptable: anything which cannot be read as qualifier of the CommonName, lengthy descriptions (always keep as short as possible). See the list of Preferred Indicators below for complete list of acceptable values.	The test that should be applied is whether or not the Indicator works well with the CommonName, for example: Postoffice, o/s War Memorial, stop 5, High Street, o/s 6
Bearing	The direction in which the vehicle is pointing when it is stopped at the StopPoint. Acceptable: N, NE, E, SE, S, SW, W, NW. Unacceptable: NNE, SSW, south west.
NptgLocalityCode	The code of the lowest level Locality in which the stop is located.	This code is associated with the locality name and other locality relationships such as Parent when the data is uploaded.
Town, Suburb, Locality Centre	Optional fields. See Simple Guide for details of how and when these fields are used.	Leave unused unless there is a local requirement for data in these fields.
Easting and Northing	Each stop much be geo-coded to 1m precision using Ordinance Survey all numeric grid references.	Longitude and Latitude are available where these have been provided by local authorities.
StopType, BusStopType, TimingStatus	The available values and their meaning should be obtained from the Simple Guide.

List of preferred indicator values (input not case sensitive)

First issued 30 March 2010

• Amended 3 December 2010 (addition of “Inner Circle” and “Outer Circle”)
• Amended 22 December 2010 (addition of “Quay” and “Berth”)
• Amended 15 February 2012 (addition of “Gate” and corrected capitalisation)
• Amended 5 March 2012 (clarification of normalisation of initial letters)
• Amended 22 July 2013 (addition of taxi rank and related provisions)

Those in bold and in brackets show the normalisation values – other values are NOT to be normalised except in terms of their initial letters, which should always be in upper or lower case as shown in this list.

These should appear before the CommonName:

• “opposite” {> “opp”}
• “opp” {> “o/s”}
• “outside” {> “o/s”} “o/s”
• “adjacent” {> “adj”}
• “adj”
• “near” {> “nr”}
• “nr”
• “behind”
• “inside”
• “by”
• “in”
• “at”
• “on”
• “before”
• “just before”
• “after”
• “just after”
• “corner of”

These should appear after the CommonName:

• “corner”
• “cnr”
• “DRT”
• “Stop”
• “Stance”
• “Stand”
• “Bay”
• “Platform”
• “entrance”
• “main entrance”
• “side entrance”
• “front entrance”
• “back entrance”
• “rear entrance”
• “north entrance”
• “east entrance”
• “south entrance”
• “west entrance”
• “north east entrance” {> “NE entrance”}
• “NE entrance”
• “north west entrance” {> “NW entrance”}
• “NW entrance”
• “south east entrance {> “SE entrance”}
• “SE entrance”
• “south west entrance” {> “SW entrance”}
• “SW entrance”
• “N entrance”
• “E entrance”
• “S entrance”
• “W entrance”
• “arrivals”
• “departures”
• “Northbound” {> “N-bound”}
• “N-bound”
• “Southbound” {> “S-bound”}
• “Eastbound” {> “E-bound”}
• “E-bound”
• “Westbound” {> “W-bound”}
• “W-bound”
• “NE-bound”
• “NW-bound”
• “SW-bound”
• “N bound” {> “N-bound”}
• “E bound” {> “E-bound”}
• “S bound” {> “S-bound”}
• “W bound” {> “W-bound”}
• “NE bound” {> “NE-bound”}
• “SE bound” {> “SE-bound”}
• “SW bound” {> “SW-bound”}
• “NW bound” {> “NW-bound”}
• “Inner Circle”
• “Outer Circle”
• “Quay”
• “Berth”
• “Gate”
• “taxi rank” (with permitted prefixes of “main”, “north”, “east”, “south”, “west” if required)

The words below can be followed by an alphanumeric string to allow for Stop codes, such as A, A1, 23, FG. AB27:

• “Stop”
• “Stand”
• “Bay”
• “Platform”
• “entrance”
• “Quay”
• “Berth”
• “Gate”
• “taxi rank”

The numeric part must be limited to 1 or 2 digits. The alpha part must be limited to 1 or 2 characters either before or after the numeric part – all in an unbroken string (of up to 4 characters).

If the Indicator is just one of these alphanumeric strings of up to 4 characters, then add the word “Stop” in front of them, except for the words “at”, “by”, “in”, “nr” or “on”, which are valid indicator values in their own right.

Words that indicate a relationship (nr, opp, o/s, adj, at, etc), can be followed by an alphanumeric string to allow for house numbers (for example, opp 23, o/s 76a). In this case, the numeric part should allow values to 9999, with or without a single following alpha character.

Stops that have an indicator in NaPTAN that does not match one of the preferred values (including those which do not have an indicator where one is required) will have a normalised indicator created based on the value of the bearing for the Stop. So a Stop with a bearing of “N” will have a normalised indicator of “N-bound” if the content of the indicator field is not a preferred value.

Stops table

The following tables describe the data stored in each CSV file. The data types of each field are the same as the XML output. For example, StopType is a 3 letter mnemonic.

SMS prefixes

The NaptanCode provides a short identifier for identifying bus stops suitable for use in SMS and other mobile services. The identifier is ergonomic for use on a mobile keypad.

1) Either digits or letters may be used (2=abc, 3=dfg, and so on, so that a single tap can be used for each character. For example ‘manwapga’ and ‘6269242’ are equivalent.

2) Successive digits are avoided, to avoid input delay and reduce input keying errors.

3) The digits 0 and 1 (which are likely confused with the characters O and I) are not used except in the London Prefix.

The number is made up of a regional prefix and a suffix together making up a unique code. The prefix is 3 characters (a/2-w/9) except in London where it is the single digit, 1.

Each NaPTAN administrative area has one or more reserved SMS prefixes that are used to create the SMS – in other words – NaptanCode for the stop points in its domain. These SMS prefixes are part of the National PT Gazetteer data and ensure that codes are unique nationally. They are chosen as far as possible to be memorable. For example, Manchester’s code is MAN and Andover’s code is AND.

Suffixes are allocated by each authority.

This table shows the current SMS Codes and ATCO Area code prefixes.
