Talk:E.164

message: Is anybody aware where the phone providers usually buy the phone numbers from? I am looking for a telephone equivalent of InterNIC. 
:First the ITU assigns country codes, then there will be some regulatory body that manages the national numbering plan i.e. phone number/area code assignment etc. For information about your country's numbering plan check out the ITU national numbering plans. If you're in North America, then check out Nanpa 
::Unlike IP addresses which are fixed length and space is given out as nessacery, each "country" (sometimes for historical or political reasons country codes don't quite line up with independent countries) gets a prefix from the ITU and then gets to do pretty much what they like with the numbers after it (there is an overall length limit on the international number but its at least a couple of digits longer than most actual phone numbers are so its hardly a pressing limitation). So there is no need for an international body to enforce efficiant use (like there is with IP addresses) just to make very occasional new allocations when countries split.

thread_title: Example needed

message: The table says the number of digits is 15 - (cc + x) = 8 - 11, but both cc and x have a minimum of 1. That means the maximum length should be 15 - (1 + 1) = 13. Is there some kind of relationship between cc and x that means they have a minimum sum of 4?  — Preceding unsigned comment added by 2001:4898:80E8:0:0:0:0:613 (talk) 17:26, 16 February 2016 (UTC)
thread_title: Number structure for networks table

message: As of this writing there is no evidence in corresponding ITU-T documents that the maximum phone number length has increased fom 15 since 2011/10. http://www.itu.int/itu-t/recommendations/rec.aspx?rec=10688&lang=en So I will rollback the change to 30 significant digits back to the previous version. Of course, this is up for debate. HerrFolgreich (talk) 12:22, 23 November 2016 (UTC)
thread_title: Change to max number length

message: AFAICT E164 is dead. At least in NL. see: http://enum.nl  (all activity has been suspended, so no production status there)
reverse lookups to e164.arpa seem to be dead as well.  e164.org points to an insurance company in Austalia.  — Preceding unsigned comment added by 2001:980:9008:666:192:168:6:24D (talk) 22:42, 6 May 2018 (UTC)
thread_title: End of Life?

message: Since the page is protected, I can't make the edit myself, but it is worth changing the tables in the "Number Formats" session to better indicate that the hyphen in sentences like "maximum 15 digits − number of digits in the Country Code" should actually be read as "minus" (i.e. [maximum 15 digits] minus [number of digits in the Country Code]). I was having trouble parsing the sentence because I was reading the minus as a dash/hypen. Kenileb (talk) 23:16, 17 April 2024 (UTC)
