Hi Carlos, This depends on how you port. Are you acting as a facilities-based LEC with access to NPAC and tools like PortPS? In that case, it's (somewhat) straightforward to find LNP rules from carriers you're porting away from. A Google for "Teliax LNP Rules" for example brings up our LNP business rules that describe how to obtain a CSR or submit an LSR. Replace Teliax with $carrier and you might be surprised by the results. Surprised, as in, going from zero to LSR sent with CenturyLink took almost two full days...but porting from Bandwidth CLEC took almost no time at all since they publish their LNP rules and processes in an easy-to-find manner. My experience has been, the more internet-oriented the company, or the smaller the company, the easier it is to port numbers out. Some carriers like Level 3 are large, but internet-oriented, and so their LNP tools and portal make LNP very easy. Not to rag on CenturyLink, but as a tiny carrier, I had to submit 3 separate LSOG-type forms for a simple port. Just to put it out there, ATIS offers the NGIIF Contact Directories. It only requires an email to register and gives you access to *some* LNP (and repair) contacts: http://www.atis.org/ngiif/contactdir.asp If you're porting via 3rd parties (Carrier does the porting on behalf of you, and your customer) this gets difficult. Porting without access to LNP portals or CSR information can be brutal. In this case, I'd echo Matthew C.'s comments, get a phone bill (or way better, a CSR) from your end-user and submit it along with your LOA. CSRs are king, some carriers just don't offer them at all, others darn-near require them to port out (which, by the way, requiring a CSR to be obtained prior to a port is against the rules) but as you said, you can get incorrect CSRs from LECs with outdated or otherwise silly records. One last thing, I'd really encourage all carriers to publish accurate and updated information in the NGIIF contact directories and publish accurate LNP business rules...and make them easy to find :) LNP is inevitable, might as well make it as easy for the next LEC as you'd want it easy for you.

What do some of you do to assure the highest possible accuracy and success?
