Syntax

ZIPNAME(zip-code)


Arguments

zip-code

specifies a numeric or character expression that contains a five-digit ZIP code.

Tip: If the value of zip-code begins with leading zeros, you can enter the value without the leading zeros. For example, if you enter 1040, ZIPNAME assumes that the value is 01040.

Details


The Basics

If the ZIPNAME function returns a value to a variable that has not yet been assigned a length, by default the variable is assigned a length of 20.

ZIPNAME returns the name of the state or U.S. territory that corresponds to its five-digit ZIP code argument. ZIPNAME returns character values up to 20 characters long, all in uppercase.


How the Zip Code Is Translated to the State Postal Code

To determine which state corresponds to a particular ZIP code, this function uses a zone table that consists of the start and end ZIP code values for each state. It then finds the corresponding state for that range of ZIP codes. The zone table consists of start and end ZIP code values for each state to allow for exceptions, and does not validate ZIP code values.

With very few exceptions, a zone does not span multiple states. The exceptions are included in the zone table. It is possible for new zones or new exceptions to be added by the U.S. Postal Service at any time. However, SAS software is updated only with each new release of the product.


Comparisons

The ZIPCITY, ZIPNAME, ZIPNAMEL, and ZIPSTATE functions accept the same argument but return different values:


Examples

The following SAS statements produce these results.
