SMS senderID

What is a senderID?

Also called TPOA (Transmission Path Origin Address), this parameter carries the SMS sender’s number or designation. Depending on the local constraints enforced by the mobile operators, different types of senderIDs may or may not be available on mobile networks across the World.

What types of senderIDs are available?

A. Numeric SenderIDs

  • They can be made of up to 16 digits usually representing a phone number in the cases when the SMS invites the user to respond or to call back.

  • According to the length and format of the numeric senderIDs, they can be segmented in 3 sub-types.

3 different types of numeric senderIDs:

Short-code
  • Example: 123
  • 3 to 7 digits in length according to the countries
  • They are digit sequences shorter than telephone numbers that have been designated to be memorable.
  • They are usually used for SMS notifications or value added service based on 2-Way SMS interactions (polls, challenges, information requests, unsubscriptions, etc.).
Local long-code
  • Ex: 91046180 (Local to Singapore)
  • Their format varies according to the countries, but are usually between 7 and 12 digits in length.
  • They are digit sequences that represent telephone numbers without the international prefix.
  • They are usually used in the cases when the senderID must be identified as an active phone number that can be called and messaged (ex: sending SMS notifications with the support phone number of your company).
International long-code
  • Ex: +6591056180 (Singaporean international long code)
  • They can be made of up to 15 digits and should start by a “+” sign.
  • They are telephone number in the international format (starting with the international prefix and followed by the local long code stripped from its leading 0).
  • They have the same purpose as the local long-code but can be used in an international context and the replies will be routed back correctly to the telephone number even from a different country.

 

 B. Alphanumeric SenderIDs

  • Ex: Wavecell
  • They can be made of a combination of up to 11 digits and uppercase of lowercase letters and spaces.
  • They are used for identifying your service name or brand name to your users and consumers receiving the message: the recipient will see the message as coming from your brand name as if he had registered a name for a number in his phone contacts.
  • It is not possible to reply to an alphanumeric senderID, the response will not be routed back to any telephone number. Considering this, alphanumeric senderIDs should be only used with opt-in users who have been given a means to opt-out of your SMS notifications. It is recommended to include a means to opt-out at the end of your message.
