Guidance and Restrictions
Message Classification in India A2P messages are classified as domestic or international. Domestic - To be able to send domestic traffic, a corporation must have a local legal entity and office in India. Companies must register as a PE (Principal Entity) on the DLT platform, which necessitates the submission of a company registration certificate and KYC documentation. International traffic refers to any traffic from companies that does not fall under the description of domestic traffic provided above. Messages are further classified as transactional or promotional. Transactional refers to a message prompted by a transaction completed by the Subscriber.who is also the Sender's customer, provided that the message is sent within thirty minutes of the transaction's completion and is directly related to it. The transaction may be a banking transaction, the delivery of an OTP, the purchase of goods or services, etc. Promotional communications are commercial communication messages sent without the recipient's explicit agreement. Promotional communications may only be sent between 0900 and 2100 hrs local time. Combining all of the above: Domestic Transactional - You must use a pre-registered 6-letter word (alpha) as the originator, and the end user's consent must be verifiable and explicit.Consent is valid for only six months. Domestic Promotional - Only pre-registered 6-digit (numeric) originators are permitted; no alphas. You must obtain verified and express consent from the end user. Consent is valid for only six months. Domestic Transactional and Promotional - a two-letter prefix will be appended to the beginning of the alpha originator upon handset delivery (e.g., VK-OPNMKT). The two-letter prefix denotes the Indian network operator (first letter) and the "circle" or region (2nd letter) in which the communication is delivered to the end-user's network. As a result, in this example, VK refers to Vodafone as the network operator in the Kolkata "circle." International transactional and promotional originators will be assigned a random short or long code.The Do Not Disturb (DND) registration exists. If a subscriber has opted in, any promotional messages will be banned. You can send up to 100 text messages each day to an end user. 2-way For a 2-way reply path, a long or short code originator must be included in the message body. This is the market standard for two-way A2P SMS in India. If a user attempts to respond to the original sender of the message, the message will fail on the device side. There are numerous regulations in India. For more information, please contact us.
