More often than not, higher-level engineering positions require that individuals obtain government certification as licensed professional engineers. The State of South Dakota is no different in that requirement.
Regulations by the South Dakota Department of Labor and Regulation were put in place to define the proper use and display of the South Dakota engineer’s seal stamp. Professional engineer seals and stamps such as the South Dakota engineer’s seal stamp are used to certify that the individual is qualified and has the authority to take legal responsibility for engineering projects. Rules may also require that professionally licensed and certified engineers must carry out engineering drawings, repair, analysis, and supervision of engineering work and affix their South Dakota engineer’s seal stamp --especially in times when public welfare or property is at risk.
State of South Dakota Specifications
Each state has slightly different requirements for their seals and stamps. The South Dakota engineer’s seal stamp requirements include the notice that all licensed professional engineers, land surveyors and landscape architects must procure and utilize appropriate seals. According to South Dakota Department of Labor and Regulation, the South Dakota engineer’s seal stamp must contain the following information:
- Licensee’s name and number
- An accurate title, e.g. Architect, Land Surveyor, Professional Engineer
- 2” diameter outer circle
- 1-1/4” diameter inner circle
- “Licensed” or “Registered” language
Electronic seals (eSeals) as well as embossed seals and rubber stamps are all sufficient to represent a licensee’s status as a South Dakota professional engineer.



Seal Usage Requirements
When there are multiple pages of a document or specification, acceptable use of the South Dakota engineer’s seal stamp states that the seal be applied to the first page or cover sheet for a specification book as long as the pages are numbered. However, individual sheets of drawings or plans must each be sealed singularly by your South Dakota engineer’s seal stamp. Please note that the use of the South Dakota engineer’s seal stamp by petroleum release assessors and interns is strictly prohibited, so protect your seal or stamp from theft or loss.
Safe Handling of Electronic Seals
There are specific rules limiting use of electronic seals (eSeals) in the State of South Dakota. Language detailing the original issuance of the seals, signatures and dates must be added to all electronically-submitted or transferred files and digital representations of physical files are not accepted as certified documents in the State of South Dakota. Instead, documents meant to be sealed and signed must have some measure of electronic authentication attached to or associated with the documents.
