Starting from 20:30 on January 8, 2021, the itinerary card will no longer mark the names of cities and towns containing medium- and high-risk areas in red, but will instead mark the names of cities and towns containing medium- and high-risk areas in brackets after the city names. Notes are only used as travel tips and are not related to health status.

On March 30, the national government service platform "Epidemic Prevention Health Code" has integrated information related to the "Communications Big Data Itinerary Card", which can display the user's itinerary information in the health code, including whether they have been to medium- and high-risk areas. Now, we can support the “one code universal” health code. ?

Users directly search for "health code" in Baidu App, and the search results can simultaneously display the user's local health code and the "epidemic prevention health information code" of the national government service platform. The "Communications Big Data Itinerary Card" information bar has been integrated under the "Health Code" on the "Epidemic Prevention Health Information Code" page, which can display travel information such as whether the user has been to medium- and high-risk areas.

In September 2021, in order to help people travel safely, the national government service platform integrated the health code and itinerary code into a "one-page view". When you open the Alipay health code, you can see the itinerary code at the same time. This means that the health code and the itinerary code have been fully integrated into one page on one page across the country.
