In a recent blog post Albert Wang, a global policy manager with Bing Ads, announced that as of now plain text phone numbers will no longer be supported as plain text entries within Bing advertisements. Bing wants you to focus on displaying your contact information via Call Extensions or Location Extensions, two features centered on displaying contact information directly within your ads. Current advertising campaigns will not be affected by the change until June so long as the ads aren’t changed in any way, shape, or form. That means no updates, including typo corrections – or the new policy checks will be applied to your ad.
Due to a change in our editorial policies, starting February 2015 in the United States, United Kingdom, Hong Kong and Taiwan, phone numbers will only be allowed through the use of Call Extensions or Location Extensions. The ad, title, body, URL, and any other ad extensions, such as Sitelink Extensions, can no longer feature phone numbers in plain text.
