In Wisconsin, every engineer has to have either an embossing seal or a rubber stamp that conforms to the rules that are set out by the Engineering Board for the state. In some states, the requirements are less stringent than they are in others, but Wisconsin is a state that has fairly strict standards. You do have some flexibility, though, in that you can use either a seal or a rubber stamp.
The Requirements
Wisconsin PE embossers or stamps must comply with board specifications. The overall diameter can be no smaller than 1 5/8 inches, and no larger than 2 inches. Each stamp or seal must include the name of the registrant, the permit number, and the name of both the city and the state. You can, however, use an abbreviation for the state. The typical seal is 1.625 inches in diameter.
The Law
Under Wisconsin law, you can use a Wisconsin PE embosser seal that includes the information supplied above, or a rubber stamp that is identical in design, content and size to a board approved seal.
Every set of documents, drawings, reports, and plans that is submitted must be signed, sealed, and dated by either the registrant or the permit holder who was responsible for directing and preparing the written material.
If more than one sheet are bound together, then the permit holder or registrant may sign, date, and seal only the index sheet or the title, provided that the signed sheet clearly identifies all the other sheets in the volume, and that any sheets that are prepared by any other permit holder and registrant are also signed, dated, and sealed by the primary registrant or permit holder. This applies also to revisions.
All Wisconsin PE embosser seals or stamps that are affixed to specifications and drawings must be original. Electronic scans are not permitted, nor are stickers. All stamps and seals must be signed and dated as follows:
- In permanent ink that contrasts with the background and the seal
- Using an approved electronic signature
- Adhering to any other requirements for seals and signatures that are required by statute
Out of State Engineers
If plans, calculations, and specifications have been prepared by an engineer other than one registered in the State of Wisconsin, they can be submitted providing that they have been prepared by an engineer who is licensed in another state, or under the supervision of an engineer licensed in another state. Then they must be certified by a professional engineer or an architect registered in the state of Wisconsin, along with statements to the effect that they comply with all state building codes and other laws. The reviewing engineer or architect must state that they will be responsible for supervising the construction work, adhering to state, county, and municipal requirements. An explanation must also be provided as to why the supervising engineer is not actually performing the work.

Frequently Asked Questions
What are the Wisconsin PE embosser requirements for size and information?
A Wisconsin PE embosser or rubber stamp must follow Wisconsin Board specifications. The seal must be between 1 5/8 inches and 2 inches in diameter and include the registrant’s name, permit number, and the city and state. The state name may be abbreviated.
Is a rubber stamp allowed instead of a Wisconsin PE embosser?
Yes. Wisconsin allows either an embossing seal or a rubber stamp, as long as the stamp is identical in design, content, and size to a Board-approved seal. This gives engineers flexibility while still meeting state requirements.
Do Wisconsin engineering documents need an original seal and signature?
Yes. Documents, drawings, reports, and plans submitted in Wisconsin must be signed, sealed, and dated by the registrant or permit holder responsible for the work. Electronic scans and stickers are not permitted for the seal itself, and the seal must be original.
Can I use an electronic signature with a Wisconsin engineer seal?
Yes, if it is an approved electronic signature and it complies with applicable statute requirements. The seal or stamp must still meet Wisconsin’s rules, and the signature must be applied in a way that is legally acceptable for the submitted document.
Can one Wisconsin PE embosser be used for bound sets of plans and revisions?
Yes, in some cases only the index sheet or title sheet needs to be signed, dated, and sealed if the bound set clearly identifies all included sheets. However, the responsible engineer must still ensure that all applicable sheets and revisions are properly covered under Wisconsin rules.
What should out-of-state engineers know about Wisconsin PE seal requirements?
Plans prepared by an engineer licensed in another state may be submitted if they are properly certified by a Wisconsin-registered professional engineer or architect. The reviewing Wisconsin professional must state that the work complies with state codes and that they are responsible for supervising the construction work as required.
