Number overview
050-3100-9434 is an IP phone number (the 050 prefix). Multiple directories carry user reports describing sales calls in the name of the job-listing site Bizlista, pitching job-ad placements to corporate recruiters (as of 2026-08-03). jpnumber registers the number under that name. We could not confirm the number on the job site's own official page.

How to handle this call
Get every condition in writing
Consumer centers in Japan receive complaints about job-ad telemarketing whose free period silently converts into a paid contract. Never agree by phone; check the terms in writing or on the official site.
You may simply decline
Re-soliciting someone who has declined is prohibited by law. Say no clearly and hang up.
