181 are available to new customers.
#These codes are available for assignment by all BOCs.
(1) Arrangements were made to activate a single line number in 800-246
to accomodate a customer with a shared (Southwestern Bell and AT&T)
service in the state of Oklahoma. Their original number was 800-642.
However, due to a typographical error, their advertising was released
as 800-246. 800-246 in originating serving offices (OSOs), serving
Oklahoma NPAs only, should be routed to the AT&T POP and subsequently
to the INWATS database. All other OSOs should vacant code 800-246.
(2) 800-250 Has temporarily been assigned as a test number for testing
purposes.

(1) PER the LERG, 462 is an AT&T-C 800-NXX. a 1982 System Letter
designated 442 and 462 as assignable for intrastate traffic only.
Puerto Rico is, justifiably, completing intra-island traffic with it
and thus cannot send 800-462 calls to the mainland. Customers
experiencing this difficuly will be handled on a case-by-case basis.
