Lookup Reassigned Number is Now Generally Available

Users frequently change their phone numbers: a Gallop poll shows 55% of users globally changed their phone number every two years and Twilio’s research shows up to 10% of users in the US changed their phone number annually. When a user changes their number, the old one can be reassigned to someone else. Whether you're engaging with customers via voice or SMS for user verification, promotional offers, alerts, notifications, and general user engagement, businesses can face significant challenges.

This creates a risk: if a business's records are not updated, messages may be sent to the wrong recipient. This not only wastes resources but can also result in unauthorized contact, potentially leading to hefty fines in certain countries. 

Twilio can help businesses tackle these challenges and knows that when contact reaches the intended users at the right moment, conversion rates can soar, driving increased engagement, loyalty, and revenue for the company.
