Bill is correct. A LEC circuit number would look more like this:

The first two digits are the last two digits for the LATA in the area where the circuit terminates. In the above example, this circuit is in LATA 236. Maybe this will help you in digging deeper. Once you have this number, then BellSouth will have a much easier time in tracking the carrier down for you.
The 1st two numbers of the circuit id known as the prefix are not in many cases the LATA. You are correcting in stating, there IS a direct connection between prefix and LATA…. and the prefix in SOME cases will match the last two digits in the LATA. That’s not by accident either but the rule is not as simple as the prefix is the last two of the LATA.
LEC’s will have different prefixes for Access (cross-lata) and non-access (intra-lata) circuits in the same LATA. So, every LEC within an area will have a minimum of TWO (maybe more) pre-fixes in one LATA.
Different LEC’s operating within the same LATA will be required to use different prefixes also.
For example, here in the area where I live and work there are 3 ILEC’s operating in the same LATA. ATT/SBC uses 3 prefixes in the area (one DOES match the last two of our LATA.) My company uses two prefixes and a third ILEC also uses two different prefixes. So, of the 7 in play here only one matches and will identify the LATA.
