What is phone number cleansing?

Last Updated: Sep 22, 2018 02:45PM UTC

When end users enter their phone number in a form, the number is not always properly formatted based on International Dialing Rules, especially in markets outside the United States. A phone cleansing mechanism is provided for you that automatically cleanses phone numbers by adding or removing leading digits in the phone number based on the country, city, and message type (SMS vs. Voice) or adding digits based on in-country or out-of-country dialing rules by phone type. Phone number cleansing can improve SMS and Voice deliverability by more than 10 percent in most markets.
