Actually 10 digit is correct. The eleventh digit is the access code, which technically should not be included. >908 is already included? 201/908 split hasn't taken place yet. Ah, but the 908 NPA is diallable from many places in the US, and is already included in the BellCore V&H tape. As a matter of fact it has been there since 1/15/90. >903 is already included? 214/903 split hasn't taken place yet. The 903 NPA was included in the 7/15/90 tape. >Does 202 still include Md. and Va. suburbs? Virginia was excluded early this year, Maryland by October. >704 apparently does NOT require 11 digits for ALL toll calls? 919 does. I noted that I was not sure of all the NPA's requiring the NPA for inter-NPA calls. >706 and 905 included? (They are still used at this time for Mexico?) They will be in use until 2/91. >602 (Arizona) requires 11 digits for toll calls within it. >313 (Michigan) reduced toll calls within it to 7 digits. Please note my comment above for 919. >Perhaps you meant + to mean "has N0X/N1X prefixes, but no split >planned yet". 201, which does have a split coming, has N0X/N1X >prefixes, but uses seven digits for toll calls within it. No, I said what I meant, and I meant what I said. (Ooops, I stole that from Dr. Seuss in "Horton Hears a Who".) The plus meant that 10 digit calling was required for intra-NPA, non-local calls. I can check for NPA's with nxx's that look like npa's, but I did not chose to at this time. --> David Esan {rutgers, ames, harvard}!rochester!moscom!de
