What should a consultant do to ensure phone numbers are standardized for SMS campaigns?

1. Create a formula field to standardize the format.

2. Edit and update the data in the source system before ingestion.

3. Assign the PhoneNumber field type when creating the data stream.

4. Create a calculated insight after ingestion.

The correct answer is: Assign the PhoneNumber field type when creating the data stream.

The best approach for ensuring that phone numbers are standardized for SMS campaigns is to assign the PhoneNumber field type when creating the data stream. This method plays a critical role in how the data is interpreted and processed. When the PhoneNumber field type is specified, the system recognizes it as a specific type of data that adheres to expected formats for phone numbers. This ensures that the data is properly validated and formatted right from the start, reducing potential errors later in the pipeline. Assigning this field type can facilitate various automated processes, such as format validation, country code normalization, and even detection of invalid numbers. By defining the field type during the data stream creation phase, the overall integrity of the data is upheld, which is essential for the success of SMS campaigns where a standardized format directly impacts deliverability and effectiveness. In contrast to this, creating a formula field or calculating insights after ingestion does not address the issue at the point of data entry. While these methods may be useful for analysis or reporting, they do not inherently ensure that the phone numbers are standardized during the initial ingestion phase. Similarly, editing and updating data in the source system can be effective but may not always be feasible depending on data accessibility or governance constraints. Thus, assigning the PhoneNumber field
