Understanding the Master Index Standardization Engine

Telephone Number Standardization Components

Standardization engines use tokens to determine how each field is standardized into its individual field components and to determine how to normalize a field value. Tokens also identify the field components to external applications, like a master index application. The following table lists each token generated by the Master Index Standardization Engine for telephone data along with the standardization component they represent. You can only specify the predefined field IDs that are listed in this table unless you customize the existing data type or create a new data type or variant.
