Quick links -




On April 23, 2018, the Engineers and Surveyors Board moved to a new licensing system and online portal along with 23 other state licensing boards and commissions. The new licensing system will provide a secure platform for all your licensure needs and will allow for the board to provide better communication and customer service to our registrants and the public

Changes seen on the new licensing system-

  • Company license numbers will remain the same however the number will now be preceded by COA (Ex. COA.XXXXX). This format will appear on the online system, your certificates, and any communication from the board regarding your COA.
  • All applications, renewals, updates will be complete through the online portal. The board will no longer be accepting paper applications or checks for licensing. All renewals, new applications, name changes, service changes, responsible in charge changes, address changes, etc. will all be complete through the online portal. The only paper form still available is the Affidavit of Responsibility (form 3012) needed for each person listed in responsible charge for the firm. This form is available on website. It will need to be completed, signed, and upload to the online system when prompted.
  • Once an application is approved, the company will instantly receive an email confirmation their COA is now active and will have the ability to print their new certificate.
  • Check payments will no longer be accepted. The online portal will accept Visa, MasterCard, American Express, and Discover. You will have the option to use any credit card, debit card, or pre-paid gift card that bears one of these logos. Pre-paid cards bearing these logos are encouraged for anyone that does not have or does not wish to use their credit or debit card on the online system.
  • The board will be emailed all future communications to companies including any letters, approvals, certificates, receipts, and renewal notices.
  • You will have to ability to maintain your licensing information through the online portal including address changes, phone changes, and email updates.




Before applying for, renewing, or making any changes to a Certificate of Authorization, you will need to ensure the name you provide the Ohio Engineers and Surveyors Board matches your current, active registration with the Ohio Secretary of State.

All active COAs must have a matching, active Secretary of State charter registration number before applying to the Ohio Board. If you do not have an active charter registration number from the Secretary of State, the Engineers and Surveyors board CANNOT approve your COA application.

To check the state of your charter registration number or get information on how to obtain a Secretary of State registration number, please visit the Ohio Secretary of State’s website.



All currently active companies will need to renew their license no later than June 30, 2018. Any license not renewed by this date will expire and must cease and desist offering or providing engineering and/or surveying service in the state of Ohio.

You will receive a renewal notice by mail with renewal instructions and the security code that will be required to register in the online portal.


The board is no longer accepting any paper applications or check payments. Any paper applications or checks will be return with instructions on how to use the online system.           

If you have any difficulty registering on the new online portal, please call the State of Ohio’s Customer Service Center at (614) 644-6860. Detailed instructions on registering in the portal and using the new system are included above also.



If your company has never held a Certificate of Authorization in the state of Ohio, you will need to complete an application for a new COA. These applications will go to the Board for approval. The full process may take up to 60 days depending on board meeting schedules however you do have the option in the online application to request a temporary permit. Temporary permits are generally granted within 7 business days and would be active for 90 days or until your full application goes to the Board for approval.



The Ohio Board require each company with an active COA have at least one full-time Ohio licensed engineer and/or surveyor listed on the COA as responsible in charge. This is managed as an “affiliation” in the online portal. Changes to the affiliations will need to be complete through the online portal then approved by the board. There is a separate form you will need to download, complete, sign and then upload to the online portal when prompted. Each person listed as responsible in charge will need to be listed and have an attached Affidavit of Responsibility. All changes to the affiliations must be reviewed by Board staff to ensure compliance with Ohio law so may take a few business days to be approved in the online portal.



Any company wanting to change the name and/or DBA on their COA must complete a new application. The COA listed under the new name/DBA will have its own, unique COA number. Your old name/COA number will be made inactive with the new name being issued a new active number.

IMPORTANT! The firm name change will not be linked to the previous firm name.  Please email the Board ( to deactivate the previous firm name’s registration.  Please include the previous firm name and COA number, and the new firm name and/or the DBA name change.  If an email is not received it may delay the processing of your application.



Any changed to services provided (adding or deleting engineering and/or surveying) will need board approval. These changes may take up to 60 days depending on board meeting schedules.



If your COA has been inactive for more than one year, you will need to apply for reinstatement of the license. There are two paths to do this depending on how long the COA has been inactive.

If your license expired after June 30, 2014, you will need to use these instructions to register and complete your reinstatement application in the online portal.


If you license expired on or prior to June 30, 2014, you will need to use these instructions to register and complete your reinstatement application in the online portal.
