In response to queries from The Business Times, UOB UOB: U11 0% said that it was among the first to join IMDA's SMS Sender ID protection registry pilot in September 2021. 

I am surprised uob tried it first.

By registration it prevent scammer from impersonating OCBC in their sms headers.

You send an SMS you can insert any alpha numeric ID you want....you can call your UOB ...or OCBC or Toyota. This is done using a simple software to add the header.

By creating a registry only legitimate use can call itself UOB.
