622 Area Code
Canadian non-geographic services (6YY pool)
The 622 area code is reserved for Canadian non-geographic services. It is the first 6YY relief code dedicated to Canada beyond area code 600.
How 622 is used
Numbers in 622 are issued by the Canadian Numbering Administrator for CRTC-approved non-geographic services that work across Canada rather than being tied to a specific rate center, including specialized voice services and machine-to-machine applications. The code is dialed as a full ten-digit number (1-622-NXX-XXXX). It complements area code 600 in Canada's non-geographic pool.

History
Creation: Area code 622 was placed into service on March 23, 2015 as the first 6YY non-geographic NPA dedicated to Canada, providing capacity beyond area code 600. NANPA has reserved a 6YY relief block of 622, 633, 644, 655, 677 and 688 for future Canadian non-geographic expansion. As an easily recognizable code (matching second and third digits), it follows the NANPA convention of using such codes for special services.
Mnemonics: The digits 622 map to letter combinations on the standard telephone keypad, yielding 27 possible three-letter mnemonics. Prior to 1995, the middle digit of area codes was restricted to 0 or 1 — codes created before then cannot form mnemonics.
