TON (Type of Number)

The Type of Number (TON) setting is used to tell both your EMSE the format of the addressing (bind addressing) that will be processed for inbound messages as well as tell the Messaggio (source and destination addressing) how it should be processed for submits. There are three separate pairs of TON and NPI values; receiving addressing, source addressing, and destination addressing. These definitions are derived from the ETSI GSM 03.40 specification, which defines the SMS protocol. The SMPP specification defines the following TON values: If you wish to specific a special value for the TON, the available options are:
  • 0: Unknown
  • 1: International
  • 2: National
  • 3: Network Specific
  • 4: Subscriber Number
  • 5: Alphanumeric
  • 6: Abbreviated
Messaggio does not generally require specific TON values from your bind to our network. We store specific values as defaults for your routes, connections, and communication assets (Short Code, Long Code, Alphanumeric Code). See TON and NPI defaults below.

NPI (Numbering Plan Identification)

The Numbering Plan Identification setting is used to tell both your EMSE the numbering plan associated with your messaging. The SMPP specification defines the following TON values: If you wish to specific a special value for the NPI, the available options are:
  • Unknown = 0
  • ISDN/telephone numbering plan (E163/E164) = 1
  • Data numbering plan (X.121) = 3
  • Telex numbering plan (F.69) = 4
  • Land Mobile (E.212) =6
  • National numbering plan = 8
  • Private numbering plan = 9
  • ERMES numbering plan (ETSI DE/PS 3 01-3) = 10
  • Internet (IP) = 13
  • WAP Client Id (to be defined by WAP Forum) = 18

TON and NPI Defaults

Messaggio will generally default both your TON and NPI to the values they should be to insure your messages are delivered properly.  The default values used by Messaggio are as follows:

Short Code (3 digits to 8 digits in length)

If the source code/address is a Short Code
  • TON = 3
  • NPI = 0

Long Code (10 digits to 15 digits in length, excludes the plus sign)

If the source code/address is a Long Code the recommended settings and default settings that Messaggio will use are:
  • TON = 1
  • NPI = 1

Alphanumeric

If the source code/address is Alphanumeric (contains both letters and numbers or only letters)
  • TON = 5
  • NPI = 0
