I use http://www.localcallingguide.com/ 

It's become almost indispensable as a resource.

Hi Mike, 
thanks for the update. 
For 1, i just wanted to know if for dialing Houston from Houston (AREA Code 713) i needed to added it or not? I guess i have to ask my LEC or CLEC as you said. I got that :-D 
For 2. To call from Houston to NY, i have to dial 1-212-1234567 but also to call from Houston to Jamaica (Area code 876) i have to dial 1-876-1234567 
even 2 is questionable? I have to ask my LEC again?

Anthony, 


I'm not sure what your question actually was, but I'll attempt to answer. 


1, Depends on your LEC (Local Exchange Carrier) or your CLEC (Competitive Local Exchange Carrier) 
2. Depends on your LEC (Local Exchange Carrier) or your CLEC (Competitive Local Exchange Carrier) (But almost always require the 1 to leave your Area. 


Further detail on item 1, i've dealt with some rural areas (none recently so I don't know if they've updated their CO) that only required the last 4. I know for a fact that large area's of New Hampshire, US only require 7 digit. However Massachusetts, US requires 10 digits throughout the entire state. It depends if the LEC did a Area Code overlay or not. 


You want a real trip, lookup https://en.wikipedia.org/wiki/Telephone_exchange_names

Hi all, 
i have 2 questions that might seem very trivial (if not ridiculous) for most of you. 
1. When calling from an area XXX belonging to NANP to the same area: 
a) we may not use the area prefix and we can send only the 7 digit number 
b) we can add the area prefix and dial 10 digits 
2. when calling to another area YYY (always belonging to NANP) we always have to dial 1+10 digit number total 11 digits. It does not matter if the other area in a neighboring state or a ... Caribbean country belonging to NANP.
