About TELSA
TELSA is a free Japanese phone-number search service that helps users identify unfamiliar or potentially suspicious callers through community-submitted reviews. The site covers mobile numbers beginning with 070, 080, and 090, as well as landline numbers organized by regional area code. Visitors can search a number to check available reports and learn how others describe calls they have received, including silent calls, business inquiries, and recorded messages.
Recent reviews and recently accessed numbers provide a snapshot of activity, although the site notes that access data may sometimes be temporarily unavailable. TELSA also offers a searchable directory of area codes grouped by region and prefecture, making it easier to look up landline numbers across Japan. The service is designed to help people assess an unknown call before deciding how to respond, using shared experiences rather than claiming to verify a caller’s identity.
