The unique ID should be 3 letters followed by a dash, followed by five digits. It should be a string. For example:</P><P>Object ID 1 should generate 'Bcn-00001'<BR />Object ID 10 should generate 'Bcn-00010'</P><P>I was thinking something like:</P><LI-CODE lang="c">FacID = .str('Bcn-000+!OBJECTID!')</LI-CODE><P>I don't know how to make the number of zeros in front of the Object ID vary based on the number of digits in the Object ID</P><P>Thanks!</P> Thu, 16 Jun 2022 19:51:44 GMT https://community.esri.com/t5/arcgis-pro-questions/python-code-to-create-facilityid-based-on-objectid/m-p/1183723#M56273 MattCotterill 2022-06-16T19:51:44Z https://community.esri.com/t5/arcgis-pro-questions/python-code-to-create-facilityid-based-on-objectid/m-p/1183730#M56274 <LI-CODE lang="python">"Bcn-{0:0&gt;5}".format(1) 'Bcn-00001' "Bcn-{0:0&gt;5}".format(100) 'Bcn-00100'</LI-CODE><P>plus other variants</P> Thu, 16 Jun 2022 20:26:00 GMT https://community.esri.com/t5/arcgis-pro-questions/python-code-to-create-facilityid-based-on-objectid/m-p/1183730#M56274 DanPatterson 2022-06-16T20:26:00Z https://community.esri.com/t5/arcgis-pro-questions/python-code-to-create-facilityid-based-on-objectid/m-p/1183750#M56278 <P>Thanks!</P> Thu, 16 Jun 2022 21:07:53 GMT https://community.esri.com/t5/arcgis-pro-questions/python-code-to-create-facilityid-based-on-objectid/m-p/1183750#M56278 MattCotterill 2022-06-16T21:07:53Z
