This free Access database of ZIP codes provides database designers with a valuable tool to assist in mapping ZIP codes to a city/state pair and even provides the latitude and longitude of that location. The database contains three tables: the ZIP Code table, the Class table and the State table.

The ZIP Code table contains six fields:

• ZIP Code is the five digit ZIP code and is the primary key of this table.
• Latitude is the latitude of the location, to five decimal places.
• Longitude is the longitude of the location, to five decimal places.
• Class is the class of the ZIP code. This field is a foreign key to the Class table.
• City is the name of the post office serving this ZIP code.
• State Code is the two-digit state code, as defined by the Federal Information Processing Standards. It is a foreign key to the States table

The States table contains three fields:

• State Code is the two-digit state code, as defined by the Federal Information Processing Standards.
• State Abbreviation is the commonly accepted postal abbreviation for the state.
• State Name is the full name of the state.

The Class table contains two fields:

• Class is the one character class code.
• Descripton is a text field describing the class in further detail.

I’ve added a query, “Show All ZIP Codes” which lists the city and state pair associated with each ZIP code for your reference. You may wish to build additional queries for your specific needs.
