Apple has launched a new portal that will allow healthcare providers, labs, and other businesses to submit information on COVID-19 testing locations, which will then be displayed on Apple Maps after review and approval by the company.

The portal provides a template in CSV format, which is to be filled up by the relevant healthcare providers and labs. The template asks for information like testing hours, referral requirements,  appointment requirements, testing location type, and much more. The file can then be emailed to Apple for review, from a business email address. Alternatively, new testing locations can also be submitted via Apple Maps app, by tapping on the 'i' button and selecting "Add a missing place".
