How the site works
Every page is built on CNAC’s public register, imported and checked weekly; community reports are moderated before publication. The site never identifies the subscriber behind a number. Methodology · Contact
Allocation source: Canadian Numbering Administrator (CNAC), the registry that records which carrier a central-office code was originally issued to. An allocation says who was issued the prefix, not who serves the number today: numbers can be ported between carriers, and caller ID can be spoofed outright.
