==Aware==
Is anybody aware where the phone providers usually buy the phone numbers from? I am looking for a telephone equivalent of [[InterNIC]]. {{U|Wk muriith}}

: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 [http://www.itu.int/itudoc/itu-t/number/ ITU national numbering plans]. If you're in North America, then check out [http://www.nanpa.com/ Nanpa] {{IP|134.226.1.62}}

::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.

==Example needed==

An example or two would be helpful in explaining the standard to the reader. -- [[User:Beland|Beland]] ([[User talk:Beland|talk]]) 00:54, 1 April 2010 (UTC)

==Number structure for networks table==
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?  <small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/2001:4898:80E8:0:0:0:0:613|2001:4898:80E8:0:0:0:0:613]] ([[User talk:2001:4898:80E8:0:0:0:0:613|talk]]) 17:26, 16 February 2016 (UTC)</small><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

Looks like this has been fixed

How do you put it on youtube so everyone can see [[User:Maswans1|Maswans1]] ([[User talk:Maswans1|talk]]) 13:13, 14 April 2020 (UTC)

==Change to max number length==
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. <ref>http://www.itu.int/itu-t/recommendations/rec.aspx?rec=10688&lang=en</ref> So I will rollback the change to 30 significant digits back to the previous version. Of course, this is up for debate. [[User:HerrFolgreich|HerrFolgreich]] ([[User talk:HerrFolgreich|talk]]) 12:22, 23 November 2016 (UTC)

==End of Life?==
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.  <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/2001:980:9008:666:192:168:6:24D|2001:980:9008:666:192:168:6:24D]] ([[User talk:2001:980:9008:666:192:168:6:24D#top|talk]]) 22:42, 6 May 2018 (UTC)</small> <!--Autosigned by SineBot-->

== Edit "Numbering Formats" Section ==

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. [[User:Kenileb|Kenileb]] ([[User talk:Kenileb|talk]]) 23:16, 17 April 2024 (UTC)

The link in the External Sources is no longer valid. I want to update the link to point to https://www.itu.int/rec/T-REC-E.164/en so that it will reference a valid webpage with the intended resources from the ITU, which the original link is from.
