[VoiceOps] Abandoned Ported Numbers

Fri Oct 14 15:41:13 EDT 2022

Depends on who/what you use for NPAC access, or if you use like LTI..etc.

We built our own SOA and LSMS XML platform so we didn't have to go through a third-party like Neustar or 10x..etc.

We get a notification (via our normal XML mechanized interface) when a TN is disconnected in the NPAC back to us for any of our SPID's. Likewise there is a SOA action you can call to disconnect/remove an SV for a given TN.

Not everyone does it. But most of the iLEC's ..etc do honor it and disconnect TN's back regularly.

If you use LTI, I'm not sure how it's presented there.

How would the original carrier know? I've never seen anything about numbers being returned to us. Maybe my employees are ignoring them, maybe the emails are lost, maybe we have to fetch it from somewhere.

I know the LNP coordinator in our company occasionally sends out "NPAC Disconnects" spreadsheets of numbers that have been returned to us, so presumably this is an NPAC process.

It's been a long time since I've used NPAC personally but there is a cancel button if I recall correctly and it pushes the number back to the original pooling carrier.

Common practice is to age them out and then push them back to the original block holder.

CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe.

Say a subscriber ports a number to/from a different telco.  Then, after
some time, the subscriber decides they no longer want the phone number
(or phone service in general).  What should be done with this abandoned
number?

Should the number immediately be returned to the donor telco?

Should the number be returned to the donor telco after aging?

Is it permissible for the recipient telco to add this number to their
inventory and then re-assign the number to a different subscriber?
