Confirm if AWS SNS uses Singapore approved aggregator

Hi Team,

Our project is based in Singapore and we use AWS SNS for sending messages to users. We would like to know if AWS SNS service setup uses Singapore's approved list of aggregators. Please refer to the link 'https://sgnic.sg/docs/default-source/sms-registry/listpa.pdf' for the list of approved aggregators in Singapore.

Additionally, from this link https://aws.amazon.com/sns/sms-pricing/ and then selecting Singapore for Outbound we see below networks

1. Circles
2. GRID Comms
3. M1
4. SingTel
5. SingTel Mobile
6. Singtel
7. StarHub
8. StarHub Mobile
9. TPG Telecom

In the above list there exists Circles,GRID Comms,TPG Telecom which are not present in Singapore's approved list of aggregators. So how do we confirm/verify that SNS is using once of the approved aggregators.

Thanks & Regards, Rohith
