Business Address: This must match the address shown on your business documents.
Review & Submit: Double-check all fields before submitting.
Once submitted, your brand information will be reviewed by our carrier partner. This process typically takes 2–3 business days. You will receive an email notification when your brand is verified.
You will not be able to move to the next step by clicking on the ‘Next’ button unless the brand is verified.

Required Information:
-
Campaign Description
Describe the purpose of the campaign clearly (e.g., OTPs, appointment reminders).
Descriptions must align with your sample messages.
If you are in the financial domain, include the term “Direct Lending” where applicable.
Examples:

Rejected: “Customers sign up.” (too vague)
Very Important:
If you collect customer information through a form or similar method on your website and intend to contact them via SMS, it is essential to clearly state this at the point of data collection. The form must include a clear consent statement such as:
