Per Wikipedia, the number itself has quite a history since the release of the song: In some cases, the number was picked up by commercial businesses or acquired for use in radio promotions. In 1982, WLS radio obtained the number from a Chicago woman, receiving 22,000 calls in four days.[7]
In 1982, Southwest Junior High School received up to two hundred calls daily asking for Jenny in area code 704.[7] Brown University obtained the +1-401-867 prefix in 1999, assigning 867-5309 to a student dormitory room which was promptly inundated with nuisance calls.[10]
In 2002 the university transferred the number to Gem Plumbing & Heating,[11] a local business in Lincoln, Rhode Island. Gem began using the number in advertising campaigns both in Rhode Island and in eastern Massachusetts (area code 617), trademarking the number in 2005.
A February 2004 auction for the number in a New York City area code was shut down by eBay after objections from Verizon; bidding had reached $80,000.[12]
A subsequent February 2004 auction for the number in area code 800 and 888 listed Jeffrey Steinberg's Philadelphia business JSS Marketing for sale, including both numbers as part of the bundle. This circumvents eBay restrictions which prevent selling the numbers on their own.[13]
In 2004, Weehawken, New Jersey resident Spencer Potter picked up the number for free after discovering to his surprise that it was available in the 201 area code, hoping it would improve his DJ business. Unable to handle the overwhelming volume of calls, he sought to sell the number on eBay in February 2009. Although bids reached $1 million, his inability to confirm the identity of the bidders led him to sell it privately to Retro Fitness, a gym franchise with a location in Secaucus, New Jersey that felt the 1980s origin of the number tied in perfectly with their business's retro theme.[4]
In 2006, Benjamin Franklin Franchising, a large national plumbing franchise, began using a toll-free version of the number (+1-866-867-5309). In 2007, Gem brought suit against Clockwork Home Services, the parent company of Benjamin Franklin Franchising, alleging a violation of its trademark. Clockwork contended that Gem's trademark was invalid. Effective in May 2007, Clockwork was ordered by a court to stop using the number in New England.[14]
As of 2011 +1-866-867-5309 remains in the hands of Benjamin Franklin Franchising as a valid method of reaching BFF customer support.[15]

In July 2009, a Pennsylvania company had the number assigned to a Vonage phone line in the name of a small business, and then listed the entire business for sale on eBay.[18]Whereas telephone numbers are the legal property of the wireline carrier, the logic behind this company and several others was that Vonage as a VOIP provider did not own the numbers, making them open for sale, with eBay being the typical medium.[19][20]
When area code 855 was opened in 2010, +1-855-867-5309 was taken in the first 47 seconds on the first day, while Pennsylvania 6-5000 was assigned on the twenty-first day.[21]
A captive RespOrg "Voice Box International", controlled by the same people who operate "5309 Partners" and "Five309 LLC", also reserved +1-844-867-5309 in the first few seconds after that area code's December 7, 2013 opening.
[22] In January 2013, Five309 LLC announced plans to use 855-867-5309 and 888-867-5309 to promote website JennySearch.com[23] but as of 2013 that site is not being actively updated.
