After loading a map based on zip codes USA_Zip_codes, I have attempted to join an external zip code file. None of the records join. The map shows the field format as Text length = 10, Read Only = no. The excel spreadsheet (xlsx 2016) is using a column called Zip_code with a format text. No records join on these fields no matter what I do. Any suggestions? My ultimate goal is to simply create a map of gradient shaded zip codes based on a value range. Thanks .... I am new to ArcMap
