An unknown caller is not automatically a scammer. A lookup gives you time to check before replying or sending money.
The same habit of checking helps across Toronto, Montreal, Vancouver, Calgary, Ottawa, Edmonton, Winnipeg, Quebec City, Halifax, Mississauga, Brampton, Surrey, and Hamilton—and across Ontario, Quebec, British Columbia, Alberta, the Prairies, and Atlantic Canada. Provincial flavour matters when a text borrows the tone of the CRA or Service Canada: the brand can look right while the callback number is improvised. Numbro surfaces community notices about how that line behaved before, so you can slow down without needing an owner name.
