After the notes on codes from the site shown as source, I have also given the details given under the column headings shown after notes on codes. hence you can get your information from this site. Mexico is divided into 31 estados (states) and one distrito federal (federal district).
Notes on codes:
In the 1960s, the U.S. and Canadian postal authorities developed two-letter state and province codes, with care to avoid overlap. That is, no state code was the same as any province code. Computer systems very frequently used these sets of codes. Many companies and government agencies have to deal with data from all of North America. The Mexican authorities never got around to deciding on an official set of two-letter state codes, so anyone who wanted to use such a set, made up their own. It's not very hard to find a set of two-letter, mnemonic state/province codes for all three countries with no overlap, so some groups did just that; others didn't care about the overlap, because they were using a combination of state and country code to identify a particular division. I recently did a search and found a dozen different systems of state codes or abbreviations for Mexico, most of which were two-letter codes. They were used by industry groups (railroads, airlines) and governments (state police departments, military), among others. No two of them were identical. The 'C' states were especially mixed, so that in different systems, CP might represent Campeche or Chiapas, CH might mean Chiapas, Chihuaha, or Coahuila, etc.
A new problem has recently arisen. Almost all code systems use NL for Nuevo León. In 2002, as a result of Newfoundland changing its official name to Newfoundland and Labrador, the Canadian postal service changed the official abbreviation from NF to NL. Now, maintainers of computer systems that use two-letter codes as a primary key for the states and provinces of North America are in a quandary. If they leave the code for Newfoundland unchanged, they're no longer in compliance with Canadian postal standards. If they change it to NL to comply with Canada, they will also have to change their code for Nuevo León. If there are old archived records that don't get updated, they will have incorrect data when they are retrieved.
"Postal addressing systems" is a document available online from the Universal Postal Union. Its entry for Mexico has a list of states and their codes. Most of the codes are the same as the conventional abbreviations, converted to all capitals, unaccented. Exceptions are BC for Baja California Norte, CAM for Campeche, and QROO for Quintana Roo.
State HASC ISO FIPS Conv INEGI Population Area(km.²) Area(mi.²) Tz Capital Postcode .
State: Except for Distrito Federal, which is a federal district.
HASC: Hierarchical administrative subdivision codes.
ISO: Codes from ISO 3166-2.
FIPS: Codes from FIPS PUB 10-4.
Conv: Conventional abbreviation.
INEGI: Instituto Nacional de Estadística, Geografía e Informatica uses a two-digit code to represent each state. Most of them
are the same as the two digits in the FIPS codes. In both cases, the states are numbered from 01 to 32 in alphabetical
order. However, alphabetical order isn't quite the same in English and Spanish.
Population: 2005-10-17 census. Source: INEGI
Tz: Time zone (hours offset from Greenwich; ~ indicates daylight saving time observed)
Capital: Common name is not in parentheses; adding parenthetical parts gives formal name.
Postcode: The Mexican postal service has defined a five-digit postal code (Código Postal). The first two digits represent a
state, a part of a state, or (in Distrito Federal) a political delegation. The range of postal codes for each state is shown
