To register your sender ID for Singapore traffic, you must have a valid UEN (Singapore business registration number). 

If you don’t have a valid UEN number, you can obtain one by registering with the Accounting and Corporate Regulatory Authority (“ACRA”). For more information, please refer to SGNIC’s FAQ.

On 31  January  2023,  the  Infocomm Media Development Authority (“IMDA”) implemented the Full SMS Sender ID Registry Regime (“Full SSIR Regime”). The SSIR was set up to enable organizations to protect their customers from receiving fraudulent SMS messages that spoof organizations’ SMS sender IDs. 

Under the Full SSIR Regime, organizations that wish to send SMS messages with alphanumeric sender IDs to Singapore mobile subscribers must first register their sender IDs with the SSIR. All non-registered sender IDs will be marked as “Likely-SCAM” for a transitionary period of 6 months.  

After that, SMS messages with non-registered sender IDs will be blocked and not delivered to mobile subscribers in Singapore.

Clickatell is working with our partners to facilitate a solution to ensure our customers’ service continues and will provide the next steps for our customers shortly. 

More details on the regulations are available at this link: https://sgnic.sg/smsregistry/overview. 

Here are general guidelines for registering sender IDs. 

Each sender ID must be: 

• Within 3 - 11 characters (including spaces, underscores, and hyphens).  

• Cannot contain Chinese or Cyrillic characters. 

• Should not be generic (e.g. 'SMS' is generic and not allowed). 

Sender IDs are case sensitive, thus “Big Brand” and “BIG BRAND” are different Sender IDs. 

Customers can refer to SGNIC's Sender ID Rules of Registration for further information. 

Yes, this is a charged service. Note that Clickatell will not be charging you but the SGNIC will be charging directly.  

You can refer to the SSIR User Agreement listed on SGNIC's website for the possible costs.
