Using the Interactive ZIP Code Equivalence/Look-up Table
The interactive equivalence/look-up table below shows all U.S. 5-digit ZIP codes sorted first by state-county (FIPS) code and then by ZIP code (within county). View ZIP codes in one state using the State selection button. To locate a ZIP code of interest, either use the Find ZIP query or sort on the ZIP code column and then scroll down the table until the ZIP of interest is located.
Each row/line shows the ZIP code, state-county code, county name, core-based statistical area (CBSA) code and name, CBSA type (MSA or MISA) and metropolitan division (MD) code and name. Only some MSAs, meeting certain conditions, have component MDs. For ZIPs with no CBSA, the ZIP code is not located in a metropolitan area.
The Find ZIP start value uses ZIP 43060 to illustrate a ZIP code located in multiple counties and multiple metros. See details The Multi column shows the sequence number of the county in which the ZIP is located (00 if one county).

Multi-County, Multi-Metro ZIP Code Areas
Multi-area county and metro ZIP codes ... 30,422 ZIP codes existed as ZIP codes totally within one county (includes ZIP code areas, post office delivery locations, other fixed address delivery locations). In addition, 10,839 ZIP codes were located in two or more counties, making for a total of 41,241 unique 5-digit ZIP codes. There are many instances where ZIP code areas cross county boundaries. The equivalence table includes 55,685 ZIP codes, reflecting the occurrence of the ZIP code for each county/metro in which it was located. The following map shows ZIP code 43060 (yellow fill color) that is partly contained in three counties (names as blue labels). This view also shows that a ZIP code can be in multiple metros; each of these three counties are in different metros (names as yellow labels). The second graphic shows these ZIP codes in a tabular view.
Extended Data and Other Lookups/Equivalencing
The same data shown in this table are also available for 7- and 9-digit ZIP codes. These data are not included in the ranking table for reasons of size and typical usage. The 2.8 million record dataset can be processed with a special look-up and code assignment program.
