Niagara Business Certificates Need a Physical Address
Niagara County DBA filings require Clerk forms, payment, notarization, and a physical business address rather than a P.O. box.

Niagara County’s DBA route is specific enough to check before mailing a form. The County Clerk page hosts DBA forms and a filing procedure. An in-person filer uses the Clerk’s Office at 175 Hawley Street in Lockport, should have a second name choice in case the preferred name is already in use, must use a physical business address instead of a post office box, and should not sign until in front of the notary. The listed in-person fee is $36.
For mail filings, the Clerk recommends asking whether the name is available before submitting the notarized form, payment, and self-addressed stamped envelope.
Separate what this record proves from the next permit, tax, title, inspection, or court question.
Put Niagara County Clerk at the top of the folder for this Niagara County question. Add the exact DBA or business certificate, the date searched, and the address, parcel, account, citation, or application number that belongs with it. The saved trail is useful because it gives Niagara County Clerk a cleaner starting point if the record has changed, moved, or been folded into a newer filing path. Niagara County DBA or business certificate paperwork is less fussy when the address, parcel, citation, account, or application number is written down early.
