Their lists are already cleaned by NPA-NXX, it's just not sufficient any
more because of LNP. Looks like the TCPA compliance product from Neustar,
which someone else posted yesterday, is the best solution. Pretty cheap
too. It's just indicates intermodal porting of a number with no other info.
I know a guy who runs a site that sells the npa nxx to carrier type at a
fraction of the lerg costs

Nothing as long as companies don't offer both services. Looking up the NPA-NXX
of the LRN in LERG 6 would tell you both what the service is and if the NXX is
portable.

LERG 6 also has a portable indicator so you can tie into that when you are
pulling information from NPAC, but you can also tell somewhat because all 10
thousand blocks of the non-portable blocks are only assigned to one carrier.
There are still many rural areas that are not in mandatory pooling a
Mary Lou,
What would be wrong with the following approach?
1. Dip call, receive LRN;
2. Look up OCN from LRN in LERG12.
3. Pull carrier by OCN from LERG1, retrieve 'CATEGORY' field.

I know there are certain areas around the country that are not portable for
a few reasons. One reason is when they are served off of a remote switch,
they have elaborate e911 trunking schemes and must remain on that switch to
properly function in an isolation-type scenario.

It's in LERG 6.
NPAC is used to associate the TN to the LRN so it can go to the right carrier.
They have no concern what type of call it is other than which databases it
should be dipped from. The LERG is the authority on routing so that's the one
you'll have to look in. Also, each thousand can b
Thanks, Mary Lou. But does the NPAC have any such fields as well?Incidentally, where are the COCTYPE/SSC/COTYPE fields in the LERG? I was just getting the operator designation from LERG1, and mapping LRNs from LE
I am an AOCN and yes the LERG has fields that differentiates between wireline
and wireless. There are actually three fields that you could filter by:
COCTYPE: Identifies the type of code
SSC: Identifies the type of service
COTYPE: Identifies the type of carrier

Yeah, poking around metro Atlanta, which is quite pooled, there do seem to be quite a few A block assignments floating around.
It could be anytime the *LEC still has the entire A block. As far as how
common it is I can't really say. My cell phone and childhood phone number
are both native routed.

Aren't 95%+ rate centres pooled these days? If so, they'd still have LRNs, since LRN-guided routing is a requirement of pooling. So, who still has non-pooled 10K blocks? Is that common in metro, or largely a trai
NPAC has a service type field that indicates wireless/wireline. That
doesn't solve for native numbers though since they won't have LRN data
since they don't have LRNs. I don't remember offhand if LERG has a
wireless/wireline indication for a given [A]OCN or block.

Indeed, you'd start from the NPAC, which would get you, for a given TN, an
LRN. Then what?

If I were to offer this service or database access, I would start with my
own local copy of NPAC that I'd update every X-minutes a day. This product
is available now and has been for a while. This is the only sure-way, I
know of, to have the most accurate data to work from.
