Design of Official Seals

OAR 820-025-0005, Official Seal

(1) Seals, as referenced by ORS 672.020(2) and 672.025(2), must contain the printed name of the registrant, the date of registration, the number of the registrant’s certificate of registration, and the registrant’s professional title. The registrant’s printed name on the seal will be exactly the same as the registrant’s name on file with the Board.

(2) The size, design and content of the seal will be an exact replica, in style, of the examples shown in Exhibit 1 (Official Seals) for the profession or branch of the profession in which the registrant is licensed. (A tolerance of 1/4" is permitted as to the size of the seal). The expiration or renewal date may be made part of the seal. If the expiration or renewal date is not made part of the seal, it must be handwritten, in permanent ink, after the word “Expires” or “Renews.” Reduced or enlarged seals are not permitted on final documents. In addition to these requirements, registrants will use the following seals:

Digital Seal and Signature for Electronic Final Documents


For electronic final documents, a “Digital Seal and Signature” (“digital signature”) is acceptable as an alternative to a stamped or computer-generated image of a seal with handwritten signature in permanent ink, if:

  • The digital signature is unique to the registrant using it;
  • The digital signature is independently verifiable by a Certificate Authority (3rd Party);
  • The digital signature is under the sole control of the registrant using it;
  • The digital signature is linked to the document in such a manner that the digital signature is invalidated if any data in the document is changed;
  • The electronic file that is the final electronic document contains one digital signature that is permanently linked to it;
  • For final electronic files containing a single page, the registrant affixes a computer–generated image of a stamp that bears the phrase “digitally signed” in lieu of and in the location designated for a hand-written signature on that page. The computer-generated image of the stamp must be of a stamp as described in OAR 820-025-0001(1) and (2), including the size prescribed in OAR 820-025-0001 when the page is printed to full size; and,
  • For final electronic files containing multiple pages not considered drawings, surveys, or plats, the registrant affixes a computer-generated image of a stamp that bears the phrase “digitally signed” in lieu of and in the location designated for a hand-written signature to the title page, an index page, or a seals page, provided that the stamped page clearly identifies all the other pages comprising the electronic file. The computer-generated image of the stamp must be of a stamp as described in OAR 820-025-0001(1) and (2), including the size prescribed in OAR 820-025-0001 when the page is printed to full size.
