May 6 is the deadline to opt out of 2013 Dex Yellow Pages deliveries.

Under a settlement agreement reached with publishers of the directories, the city of Seattle has closed its opt-out site and is publicizing an industry opt-out site, www.YellowPagesOptOut.com.

Seattle residents who already opted out of yellow-pages directories through the city site will not need to opt out again, said City Council member Mike O’Brien, who sponsored the legislation that sought to limit the delivery of unwanted directories.

The publishers of the Yellow Pages successfully sued the city, saying the ordinance infringed on its free-speech rights. The city in February agreed to pay more than $780,000 to settle the lawsuit.

The directory publishers argued that many customers still rely on print Yellow Pages to make purchases or locate services. They improved their opt-out site after complaints from Seattle officials that the publisher’s site was difficult to find and didn’t result in deliveries being stopped.

Local Search Association, the trade group of several Yellow Pages publishers, said the new website is easier to use and allows customers to set preferences so they only receive the directories they want, or can opt-out of all of them.
