What is essential to confirm the phone number format for SMS campaigns?

1. Create a calculated insight after ingestion.

2. Edit and update the data in the source system prior to sending.

3. Assign the PhoneNumber field type during data stream creation.

4. Use a streaming API to verify the number.

The correct answer is: Assign the PhoneNumber field type during data stream creation.

Assigning the PhoneNumber field type during data stream creation is crucial for confirming the phone number format for SMS campaigns. By designating the field specifically as a PhoneNumber type, you ensure that the system recognizes the format expected for phone numbers, which is critical for any SMS communication. This assignment generally includes checks for standard phone number patterns, such as the correct number of digits and potentially the inclusion of area codes or country codes. The proper field type allows for more accurate data handling and processing later in the campaign, minimizing errors that could occur if the data was not initially defined appropriately. Ensuring that the PhoneNumber field is correctly set up from the start helps in maintaining the integrity of the data, thereby increasing the effectiveness of SMS outreach efforts. While the other options may touch on data handling aspects, they do not specifically address the foundational need for confirming the phone number format. Creating insights, updating source data, or verifying through a streaming API may be useful in certain contexts, but they do not provide the necessary initial validation that assigning the correct field type does.
