I worked at the phone company in northern Canada and saw these codes in the distance dialing reference guide, and noticing the gradual disappearance of the ones in Mexico.

The ones in Canada were still needed for manual-mobile phone base stations. However, although I have no direct evidence, I am compelled to surmise that within the company, each base station had its own identifier code which the company could use for intra-area call rating. Calls coming to a customer from elsewhere in Canada would be coming over such a distance that the difference between, say, Whitehorse and the Fox channel was insignificant by comparison, that the Whitehorse operator connecting the final leg of the call would inform the operator in southern Canada to use Whitehorse as the "mark code" for rating purposes. Each radio base station probably was associated with the nearest actual dial office for this purpose. BUT...

I do not know this for certain, so I did not put this into the article. GBC (talk) 02:41, 27 September 2018 (UTC)[reply]
