Area code 273 – Quebec, not yet in service
273 is a Quebec area code that has been assigned but is not in use yet: it is scheduled to go into service on 27 February 2027. NANPA records it as an overlay on 418, so it will supply new numbers across the same area rather than replacing any existing ones. Once live, local calls across the 273/367/418/581 codes will need all ten digits.
