DETROIT — A phone number tied to Harry Styles' new viral marketing campaign has roots in Metro Detroit, and fans are clamoring to find out why.

Styles, the three-time Grammy winner and former One Direction singer, has launched a new website, webelongtogether.co. The site's splash page features a wide-angle image of a massive concert crowd, shot from above, with some fans dancing, some fans with their lights from their phones lit up above their heads. The site includes a copyright notice from Sony Music Entertainment, the parent company of Styles' record label.

Click anywhere on the page and the site goes to a page that mirrors an iPhone contact screen, tied to HSHQ, which one can presume is Harry Styles Headquarters. The phone number listed under the contact is 586-533-5477, a Macomb County area code.

Call the number and it hangs up after one ring. Text it and it autofills a message, "We belong together," and sends a link that takes users to Community, a "messaging engagement platform that connects global brands, sports teams, film and TV studios, music labels, public figures, artists, and more to their audiences at scale through personalized experiences," according to a company bio.

But what in the world does Harry Styles have to do with Macomb County?

A spokesperson for Community, which was co-founded by Ashton Kutcher and Madonna manager Guy Oseary, said Tuesday, "we cannot and do not discuss our client's campaigns with outside parties." An inquiry sent to Columbia Records, Styles' record label, was not returned.

Styles, 31, has hinted that he is on the verge of announcing new music. A YouTube clip uploaded in late December featured Styles performing a piano ballad, with the words "WE BELONG TOGETHER" flashing across the screen at the end, over the same image from the We Belong Together website.

Earlier this week, posters tied to Styles with the message "See you very soon" started popping up in New York. Similar messaging popped up in other cities around the world.

So far, there's been no official word from Styles' camp on new music or touring plans. The New York Post's Page Six is reporting Styles will be performing a residency at Madison Square Garden later this year.

Styles' most recent album, "Harry's House," was released in April 2022 and included the smash single "As It Was," which topped Billboard's Hot 100 singles chart for 15 non-consecutive weeks. "Harry's House" went on to win the Grammy for album of the year.

Styles' last local performance was at Little Caesars Arena in September 2021.
