Onondaga County’s DBA route starts with the County Clerk, not a town hall. Individuals or partners conducting commercial activity under a name that is not their given name must file a DBA certificate. Before filing an original DBA, the filer must review assigned business names to make sure the desired name is available. The county page covers original, amendment, and discontinuance filings and says forms can be filed in person or by mail if notarized.
Search the name, use a physical business address, notarize the form, and include the correct filing and certified-copy fee.
Keep the name-search result, physical business address, notarized form, fees, filed certificate, and certified copies together. Use the matching amendment or discontinuance filing when the record changes.
