This is not a CARTO restriction, this is a US Government licensing protection of their zip code data source; which is not publicly available. Additionally, zip codes are considered service areas and are not actually geometric areas. As a solution, the US Census provides ZCTA data, which tabulates GIS postal codes for USPS locations by aggregating census blocks. For details about how ZCTAs are created, see [ZIP Code™ Tabulation Areas (ZCTAs™)](https://www.census.gov/geo/reference/zctas.html). If you are geocoding data and your zip codes fail, ensure you are using ZCTAs for the postal code. ### cdb_geocode_postalcode_polygon(_postal_code text, country_name text_)
