Many different sources are used in producing this database (locations, geocoding, time zones, daylight savings). Anyone familiar with Mexican locations and their naming conventions know there are numerous influential competing sources with differing standards. We make every attempt to use the most recognized and widely adopted.
Considering the improvements in Correos de México (Mails of Mexico) formerly Sepomex (Mexican Postal Service) in recent years, we now view them as authoritative when it comes to settlement and municipality naming conventions. Unless we are otherwise sure, we give greater weight to their names. See sample of actual data below and feel free to download a larger cross-section (at right).
Sample (not all fields are shown)
| PostalCode | Settlement | SettlementType | StateISO | Municipality | City | Zone | Latitude | Longitude | TimeZone | DST |
|---|---|---|---|---|---|---|---|---|---|---|
| 05330 | Memetla | Colonia | CMX | Cuajimalpa de Morelos | Ciudad de México | Urbano | 19.358328 | -99.286428 | -6 | N |
| 05330 | Ampliación Memetla | Colonia | CMX | Cuajimalpa de Morelos | Ciudad de México | Urbano | 19.358328 | -99.286428 | -6 | N |
| 09070 | Granjas de San Antonio | Colonia | CMX | Iztapalapa | Ciudad de México | Urbano | 19.364035 | -99.106626 | -6 | N |
As one would expect with Mexican data, many place names use diacritics (accent marks such as acute, tilde, dieresis/umlaut, etc.) found in the UTF-8 character set and the older ISO-8859-1 subset. If you have a legacy system limited to ASCII, see note at bottom of page.
The only state abbreviations having near universal acceptance in and out of Mexico are the ISO 3166-2 (3-character, included in this product). However, there are several large organizations (commercial as well as government agencies) that use 2-character abbreviations. Although there is much overlap, none completely agree, and none dominate. Our 2-character state is derived from the most frequently used among them all. However, some organizations require their own when transmitting data. To help, we include a supplementary relational table with 2-char states used by other sources (RENAPO/CURP, INEGI, US: Dept Homeland Security, Customs Border Patrol, DOT, FBI, USFS, PCMiler, MileMaker).
Comma-Separated Values (CSV) Text File
The Mexican postal code is a 5-digit integer. When a Postal Code boundary spans multiple settlements, each is listed as a separate record.
Name of the Settlement
Type of Settlement (Colonia, Ranchería, Pueblo, Barrio, Fraccionamiento, etc.). Very infrequently a settlement will cross settlement types; these are listed separately.
Official Settlement type abbreviation (COL, RCHER, PBO, BO, FRACC, etc.)
Full state name (México)
Unofficial two-character state abbreviation (MX)
Official ISO 3166-2 three-character state abbreviation (MEX)
Conventional state abbreviation (Méx.)
Name of Municipality (Álvaro Obregón)
Name of City (Ciudad de México)
Type of Zoning (Rural, Urbano, Semiurbano )
The format for Latitude is: 99.999999 and the format for Longitude is: ‐999.999999. Note that west longitudes (all Mexico locations), contain a negative number.
This is the time from UTC (Universal Coordinated Time), which are negative numbers in this hemisphere.
Daylight Saving Time Flag (Y/N) - Indicates whether observing Daylight Savings Time as officially recognized by the Mexican government (mostly border cities).
