</span>It is my impression that ports are technically possible anywhere<br>
within a LATA, but for business reasons most telcos won't port between<br>
rate centers.<br>
<br>
They're definitely not possible across the country because long<br>
distance calls only do the LNP lookup after routing the call to<br>
the destination tandem. (That's the "L" in LNP.)<br>
