Here you may find valid codes for a specific area: https://crs-explorer.proj.org/?latlng=44.552901,-123.266602&ignoreWorld=false&allowDeprecated=false&authorities=EPSG&activeTypes=PROJECTED_CRS A click then brings you to EPSG.org, Find in the upper right a tiny "WKT" button which shows eg.: https://epsg.org/crs/wkt/id/6559 -> WKT: PROJCRS["NAD83(2011) / Oregon North (ft)",BASEGEOGCRS["NAD83(2011)",DATUM["NAD83 (National Spatial Reference System 2011)",ELLIPSOID["GRS 1980",6378137,298.257222101,LENGTHUNIT["metre",1,ID["EPSG",9001]],ID["EPSG",7019]],ID["EPSG",1116]],ID["EPSG",6318]],CONVERSION["SPCS83 Oregon North zone (International feet)",METHOD["Lambert Conic Conformal (2SP)",ID["EPSG",9802]],PARAMETER["Latitude of false origin",43.6666666666669,ANGLEUNIT["degree",0.0174532925199433,ID["EPSG",9102]],ID["EPSG",8821]],PARAMETER["Longitude of false origin",-120.5,ANGLEUNIT["degree",0.0174532925199433,ID["EPSG",9102]],ID["EPSG",8822]],PARAMETER["Latitude of 1st standard parallel",46,ANGLEUNIT["degree",0.0174532925199433,ID["EPSG",9102]],ID["EPSG",8823]],PARAMETER["Latitude of 2nd standard parallel",44.3333333333336,ANGLEUNIT["degree",0.0174532925199433,ID["EPSG",9102]],ID["EPSG",8824]],PARAMETER["Easting at false origin",8202099.738,LENGTHUNIT["foot",0.3048,ID["EPSG",9002]],ID["EPSG",8826]],PARAMETER["Northing at false origin",0,LENGTHUNIT["foot",0.3048,ID["EPSG",9002]],ID["EPSG",8827]],ID["EPSG",15351]],CS[Cartesian,2,ID["EPSG",4495]],AXIS["Easting (X)",east],AXIS["Northing (Y)",north],LENGTHUNIT["foot",0.3048,ID["EPSG",9002]],ID["EPSG",6559]] More human readable output you get with `projinfo`: projinfo EPSG:6559 PROJ.4 string: +proj=lcc +lat_0=43.6666666666667 +lon_0=-120.5 +lat_1=46 +lat_2=44.3333333333333 +x_0=2500000.0001424 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=ft +no_defs +type=crs WKT2:2019 string: PROJCRS["NAD83(2011) / Oregon North (ft)", BASEGEOGCRS["NAD83(2011)", DATUM["NAD83 (National Spatial Reference System 2011)", ELLIPSOID["GRS 1980",6378137,298.257222101, LENGTHUNIT["metre",1]]], PRIMEM["Greenwich",0, ANGLEUNIT["degree",0.0174532925199433]], ID["EPSG",6318]], CONVERSION["SPCS83 Oregon North zone (International feet)", METHOD["Lambert Conic Conformal (2SP)", ID["EPSG",9802]], PARAMETER["Latitude of false origin",43.6666666666667, ANGLEUNIT["degree",0.0174532925199433], ID["EPSG",8821]], PARAMETER["Longitude of false origin",-120.5, ANGLEUNIT["degree",0.0174532925199433], ID["EPSG",8822]], PARAMETER["Latitude of 1st standard parallel",46, ANGLEUNIT["degree",0.0174532925199433], ID["EPSG",8823]], PARAMETER["Latitude of 2nd standard parallel",44.3333333333333, ANGLEUNIT["degree",0.0174532925199433], ID["EPSG",8824]], PARAMETER["Easting at false origin",8202099.738, LENGTHUNIT["foot",0.3048], ID["EPSG",8826]], PARAMETER["Northing at false origin",0, LENGTHUNIT["foot",0.3048], ID["EPSG",8827]]], CS[Cartesian,2], AXIS["easting (X)",east, ORDER[1], LENGTHUNIT["foot",0.3048]], AXIS["northing (Y)",north, ORDER[2], LENGTHUNIT["foot",0.3048]], USAGE[ SCOPE["Engineering survey, topographic mapping."], AREA["United States (USA) - Oregon - counties of Baker; Benton; Clackamas; Clatsop; Columbia; Gilliam; Grant; Hood River; Jefferson; Lincoln; Linn; Marion; Morrow; Multnomah; Polk; Sherman; Tillamook; Umatilla; Union; Wallowa; Wasco; Washington; Wheeler; Yamhill."], BBOX[43.95,-124.17,46.26,-116.47]], ID["EPSG",6559]] Note that I just showed an example, it is not necessarily the code you are hunting for.
