- I took the Telecom Digest guide to the 800 prefixes, turned them into a
- chart form and updated with new prefixes (including Sprint's 800-800 prefix,
- which is dialable from Canada) to the extent that the long distance network
- in Canada will allow. Further updates to this list would be welcome, considering
- the posting claiming that almost 800 NXX's have been assigned to 800 service.

- Notes on 800
-
- Much of this was adapted from Telecom Digest's guide to codes, of which
- the 800 prefixes were included. This has been updated according to new
- prefixes available under Canadian dialing.
-
- New prefixes added on top of the Telecom Digest list: 354, 388, 395, 473,
- 477, 487, 488, 676, 677, 688, 695, 745, 753, 755, 765, 766, 800, 866, 879,
- 884, 926, 927, 933.
-
- Where local telcos, such as Illinois Bell offer 800 service, they purchase
- blocks of numbers from AT&T on prefixes assigned to AT&T. They are free
- to purchase blocks of numbers from any carrier of their choice however.
-
- Often, exchanges of the form NN2 are used internally within an area code
- or region, such as 552 or 772 in Saskatchewan, or for intra-state use.
- Specific intra-state or intra-provincial uses are not mentioned in this
- document.
-
- The information was updated according to carriers accessible from Canada.
- As far as can be determined, only the AT&T, MCI and Sprint 800 services
- are accessible from Canada at present. However, 337 (assigned to First Data
- Resources) seems to be connected to MCI. This could be due to the purchase
- of some companies; the prefixes would then be assumed by the buyer.
-
- N0X/N1X prefixes for 800 service are starting to appear. The first widely-known
- one is 800 used by Sprint (as in 1 800 800 xxxx). This is the only N(0/1)X
- prefix for 800 to be accessible from Canada at present.
