SINGAPORE SMS SENDER ID REGISTRY (“SSIR”)
Sender ID Rules of Registration
- Registration of Sender IDs is on a first-come-first-served basis.
- No sharing of Sender IDs is allowed between user organisations.
- Sender IDs cannot be transferred between user organisations, unless approved by SGNIC.
- If a user organisation is seeking to register a Sender ID that is not linked to its company name or business, it may be requested to provide supporting documents to justify its choice of Sender ID.
- Alphanumeric Sender IDs should:
- have a minimum of 3 characters and a maximum of 11 characters;
- not contain non-Latin characters;
- be in any combination of upper/lower casing;
- not be generic in nature (for e.g. “OTP”, “SMS”, etc);
- not be sensitive in nature;
- not contain leading or trailing spaces; and
- only include the allowed special characters found in the Annex.
- Short codes can be registered as Sender IDs with the SSIR, provided the below conditions are met:
- Only 5-digit short codes starting with 7 can be registered;
- The short code will need to be unique to the user organisation; and
- The user organisation will need to submit supporting document(s) to the SSIR, showing that the short code was issued by a Mobile Network Operator in Singapore to the SMS aggregator that the user organisation is working with.
- Long virtual numbers (“LVNs”) can be registered as Sender IDs with the SSIR, provided the below conditions are met:
- Only numeric Sender IDs assigned by Mobile Network Operators in Singapore and sent by Participating Aggregators can be registered. SMS sent via SIM card with mobile number as Sender ID cannot be registered;
- Only LVNs from the 8 and 9 series can be registered, where you should register both the 10-digit LVN with “65” prefix e.g. 658xxxxxxx or 659xxxxxxx and the 8-digit LVN e.g. 8xxxxxx or 9xxxxxxx. The 2 versions of the LVN will be considered as one Sender ID for purposes of billing;
- The LVN will need to be unique to the user organisation;
- The user organisation will need to submit supporting document(s) to the SSIR, showing that the LVN was issued by a Mobile Network Operator in Singapore to the SMS aggregator that the user organisation is working with.
- User organisation should not register Sender ID(s) as follow:
- Suggesting a link to or associated with Singapore Government, statutory bodies, regulatory authorities/agencies, national controlling bodies and/or national movements; or
- Regarded as obscene, scandalous, indecent or contrary to law or morality in any language, or offending religious beliefs.
- For the avoidance of doubt, SGNIC has sole and absolute discretion in deciding which Sender IDs are objectionable, undesirable or unsuitable for Registration. SGNIC may delete/reject the Sender IDs or take such other action as SGNIC deems necessary or desirable in its sole and absolute discretion.
Annex: List of Allowed Special Characters in a Sender ID*
* Each Participating Aggregator (PA) has its own “Know-Your-Customer” verification processes during sign up. Each PA also has commercial and technical policies and set-up in supporting Sender IDs, which may differ from another PA. E.g., not all PA(s) may support Sender IDs that contain special characters (e.g., ?, @, *, #). User organisations should check out before engaging their preferred PA.
