Josephine La Bella, 25, who works at a payroll company, likes to tackle the delicate subject head on. Ms. La Bella, who has vigilantly monitored her credit score ever since graduating from Rutgers in 2009, has found that broaching the topic of her own credit score causes her suitors to open up, too.

In August, Ms. La Bella recalled, while at dinner in Bayonne, N.J., a date blurted out his credit score on the first outing. Instead of making things more awkward, she said, a really productive discussion followed. Since then, Ms. La Bella tries to bring up the topic soon after meeting someone.

“I take my credit score seriously and so my date can take me seriously,” she said. A handful of small, online dating Web sites have sprung up to cater specifically to singles looking for a partner with a tiptop credit score. “Good Credit Is Sexy,” says one site, Creditscoredating.com, which allows members to view the credit scores of potential dates who agree to provide the numbers.
