**Step 4:** Under Alpha Sender ID, key in <mark style="color:red;">`RedeemSG`</mark>. It is <mark style="background-color:yellow;">case sensitive</mark>, so input exactly. We have already registered this Sender ID with SGNIC.

**Step 5:** Leave ‘Step 3: Set up integration’ exactly as it is. Click ‘Step 4: Add compliance info’.

## Additional Notes

If you are only planning to send SMSes using a registered alphanumeric sender ID and not receive replies, you do not need to purchase a Twilio phone number. This is the case for RedeemSG.
