NPTG/NaPTAN Admin Area 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.  

  • Either digits or letters may be used (2=abc, 3=def, etc so that a single tap can be used for each character.  For example "manwapga" & "6269242" are equivalent
  • Successive digits are avoided, to avoid input delay and reduce  input keying errors.
  • The digits "0" & "1" (which are likely  be confused with the characters "O" & "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 three 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 i.e.  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 - eg MAN = Manchester, AND = Andover.

Suffixes are allocated by each authority.

The following table shows the current SMS Codes & ATCO Area code prefixes:
