In order to facilitate the sharing of
Telcordia
telephone routing databases between countries,
LATAs were later defined for the provinces of
Canada ,
the other countries and territories of the
North
American Numbering Plan ,
and Mexico .
Aside from U.S. territories, LATAs have no
regulatory purpose in these areas. 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 .

By-State
U.S. 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. 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.
Inter-carrier agreements, change proposals to the
Federal
Communications Commission
(FCC), and new wiring developments into rural areas
can and do often alter the effective borders
between LATAs. Many sources on LATA boundary
information conflict with each other at detailed
levels. Telcordia
data may provide the most up-to-date details of
LATA inclusions.

LATA 228 includes all of Delaware
as well as the metro area of Philadelphia,
Pennsylvania .
^
a
b
Half of LATA 636 occupies eastern North
Dakota , the
other half takes up the northwest quarter of
Minnesota .
-- ^
American Samoa entered the NANP
in October 2004 and presumably was allocated a LATA
by that time. Telcordia LERG data suggests that
American Samoa uses LATA 884.
-- ^
As of 2000, all of Canada is identified as LATA
888.

-- The Telcordia LERG Routing Guide , commonly
known as "The LERG," is a comprehensive data
product produced monthly by the Telcordia
Routing Administration (TRA)
and primarily used by telecommunications
service providers
operating within the North
American Numbering Plan
(NANP) (i.e. World Zone 1). Its data supports the
current local exchange network within the NANP and
identifies reported planned changes in the network.
The acronym "LERG" stands for "Local Exchange
Routing Guide".
-- The LERG Routing Guide provides data to
support:
-- Routing of calls by service providers
over the Public
Switched Telephone Network
(PSTN) and interconnection points of the PSTN with
the Internet
Protocol
(IP) world
-- A wide range of business needs of
companies that require information about the
network, numbering and other data in the
product
-- The LERG Routing Guide
includes:
-- Operating Company Numbers, Company Names,
Routing Contacts
-- Country
Code
Assignments
-- Numbering Plan Area (NPA) Assignments
(also known as Area
Codes )
-- Local
access and transport area
(LATA) Codes By Region
-- Destination Codes (NPA NXX
Thousands-Blocks)
-- Access Tandem Codes
-- Oddball NXXs (e.g. 911,
976)
-- Switching Entity Record detail (e.g.
Equipment Type, V&H Coordinates), including
PSTN and IP network elements
-- Rate Center details (e.g. V&H
Coordinates) and Localities (includes County of
Localities)
-- Switch Homing Arrangements (tandem and
other switch-to-switch
interconnections)
