. Area codes and LATAs do not necessarily share boundaries; many LATAs exist in multiple area codes, and many area codes exist in multiple LATAs. Originally, the LATAs were grouped into regions within which one particular RBOC was allowed to provide services. The LATAs in each of these regions are numbered beginning with the same digit. Generally, the LATAs were associated with carriers or other indications in the following manner: In addition to this list, two local carriers were made independent:

. These were assigned LATAs in the 9xx range. Since the breakup of the original AT&T in 1984, however, some amount of deregulation, as well as a number of phone company mergers, have blurred the significance of these regions. A number of new LATAs have been formed within these regions since their inception, most beginning with the digit 9. LATAs contribute to an often confusing aspect of

Due to the various and overlapping regulatory limitations and inter-business arrangements, phone companies typically provide differing types of “long distance” service, each with potentially different rates: * within same LATA, within same state * within same LATA, between different states * between different LATAs, within same state * between different LATAs, between different states Given the complexity of the legal and financial issues involved in each distinction, many long-distance companies tend to not explain the details of these different rates, which can lead to billing questions from surprised customers. Local carriers have various alternative terms for LATAs such as “Service Area” by Pacific Bell in California, or “Regional Calling Area” by Verizon in Maryland. To facilitate the sharing of

In 2000, the Canadian Radio-television and Telecommunications Commission eliminated all Canadian provincial LATAs in favor of a single LATA for Canada (888). No LATAs exist with a second digit of 0 or 1, which distinguished them from traditional area codes.


List of LATAs


US state LATAs

The city or place name given with some LATAs is the name given to identify the LATA, not the limit of its boundary. Generally this is the most significant metropolitan area in the LATA. In some cases, a LATA is named after the largest phone exchange in the LATA that was historically served by an RBOC. For example, the largest city in the Pahrump LATA in Nevada is
Las Vegas Las Vegas (; Spanish for "The Meadows"), often known simply as Vegas, is the 25th-most populous city in the United States, the most populous city in the state of Nevada, and the county seat of Clark County. The city anchors the Las Vegas ...
. Since Las Vegas was not historically served by an RBOC, the LATA is named after the smaller town of Pahrump, which was historically served by Nevada Bell (now AT&T Inc.). Also, listing under a state does not necessarily limit the LATA's territory to that state; there may be overlaps as well as enclaves. Areas that include notable portions of other states are explained, but not all LATA state overlaps may be detailed. LATA boundaries are not always solidly defined.

Local interconnection region

Canada does define local interconnection regions (LIR's), which determine where points of interconnection (POI) must be provided by Competitive local exchange carrier, competing local exchange and mobile carriers to provide local number portability. A Canadian LIR is geographically smaller than a US LATA, typically comparable in size to a small city's flat-rate local calling area or to an entire large regional municipality. In areas where a small-city Digital Multiplex System controls a group of remote switching centres, one for each surrounding village, the local interconnect region normally includes each exchange in the city plus all downstream remotes of those exchanges. In a Toronto-sized city, the LIR will include only the city itself. While the LIRs resemble local calling areas in geographic size, there are some key differences: * LIR's normally do not include incumbent local independent telephone company exchanges in locations not opened to competition, where the independent numbers are currently not portable. * LIR's do not cross provincial boundaries. Lloydminster has an LIR for each province, as does Ottawa-Hull, Quebec, Hull. * LIR's closely follow network topology, which often does not match a local flat-rate calling area as local calling is defined by arbitrary regulatory constructs. One example: The tiny unincorporated village of Beebe Plain, divided by the Quebec-Vermont border, is served by +1-819-876 Rock Island, Quebec, Canada (a remote station controlled from Magog, Quebec, Magog) and +1-802-873 Derby Line, Vermont, USA (a remote station controlled from St. Johnsbury, Vermont, St. Johnsbury). Magog and St. Johnsbury are both a long-distance call from anywhere in Beebe Plain, even though Canadian subscribers can place local calls to Sherbrooke, US subscribers can locally call Newport (city), Vermont, Newport and an international call within the village is local. An LIR assignment which follows network topology places the Canadian remote station in Magog's LIR, not Sherbrooke's LIR.Rock Island QC
