Manage sender IDs

When you create a Verified SMS agent, you include the agent's sender IDs: long codes (E.164 format), short codes, national codes, or alphanumeric codes that can send SMS messages. Associating your agent with sender IDs lets Verified SMS and the Messages app know that they can expect messages from these IDs to be from your agent.

When the Messages app receives a message from an agent's sender ID, the app attempts to verify the message by hashing the message content and confirming the hash with Verified SMS. If the Messages app receives a message that isn't from an agent's sender ID, the app treats the message like it would any other SMS message and doesn't verify the message or display any branding in the conversation.

Countries

When you associate a sender ID with your agent, you include a list of countries that your sender ID operates in. For example, if the sender ID +12345 sends messages to users in the USA and Canada, you register it with the ISO 3166 Alpha-2 country codes US and CA.

If you send a message in a country that your sender ID isn't associated with (continuing the example, if you send a message from +12345 with the country code AU), the Messages app doesn't recognize +12345 as a sender ID from a Verified SMS agent and doesn't attempt to verify the message.

One conversation per sender ID

It's a best practice to send all of an agent's messages from a single sender ID. When an agent has multiple sender IDs, the Messages app verifies SMS messages from all of the IDs but keeps messages from each ID in their own conversations. For example, if Growing Tree Bank has the sender IDs 50470 and 88464, the Messages app verifies messages from both IDs but has one conversation with messages from 50470 and another conversation with messages from 88464.

Sharing sender IDs

If multiple agents (such as those operated by different partners) represent the same brand, those agents can share one or more sender IDs. Messages from a sender ID appear in the same conversation in users' devices, regardless of which agent sent the message.
