Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience, and Interior Design and Minn. Stat. §§ 326.12, subds. 2 and 3, and 326.03, subd. 3 on 21 September 2026 · Updated 21 September 2026
Minnesota does not require a land surveyor to own or use a seal. Minn. R. 1800.4300 says each person “may, upon licensure or certification, also obtain a seal,” and that the stamped seal “may be used on documents in addition to the signed and dated certification required under part 1800.4200.” The round device is legally optional. What is mandatory is the certification: Minn. R. 1800.4200, subp. 1 provides that “The certification and signature on plans, drawings, specifications, plats, reports, and other documents that require a signature is mandatory.”
So the Minnesota purchase is a certification block stamp rather than a round seal, and the wording is yours alone. Minn. R. 1800.4200, subp. 4 gives the land surveyor sentence as “I hereby certify that this survey, plan, or report was prepared by me or under my direct supervision and that I am a duly Licensed Land Surveyor under the laws of the state of Minnesota.” Survey, plan or report. Architects, engineers, landscape architects and certified interior designers certify a plan, specification or report, so a block set from an engineer template with your title pasted on is the wrong text.
Because nothing prescribes a size or a shape for the optional seal, that part is a design decision rather than a compliance one, and you can have whatever suits your title block. Put your own name, your firm name and any credential you actually hold. Minnesota licensed you as a land surveyor, so the legend “licensed land surveyor” is yours to use; leave off any other state-issued title the state did not issue you, because that is the part some jurisdictions restrict.

Is a seal required in Minnesota?
Minnesota does not require a land surveyor to own or use a seal. Minn. R. 1800.4300 says each person “may, upon licensure or certification, also obtain a seal,” and the stamped seal “may be used on documents in addition to the signed and dated certification required under part 1800.4200.” What is mandatory is the certification. Minn. R. 1800.4200, subp. 1: “The certification and signature on plans, drawings, specifications, plats, reports, and other documents that require a signature is mandatory.” Surveyors also carry a gate the other professions do not: Minn. Stat. § 326.03, subd. 3 bars any plat, map or drawing of a survey or subdivision required to be recorded from being filed unless it bears a licensed land surveyor’s certification.
What must appear on the seal
- On the optional seal: your name
- On the optional seal: the legend “licensed land surveyor”
- In the mandatory certification block: the prescribed land surveyor certification sentence
- In the block: your signature
- In the block: your typed or printed name
- In the block: the date
- In the block: your license number
Two things separate the surveyor from the rest of the Minnesota board’s licensees. First, the certification sentence has a different object. Minn. R. 1800.4200, subp. 4 gives the land surveyor wording as “I hereby certify that this survey, plan, or report was prepared by me or under my direct supervision and that I am a duly Licensed Land Surveyor under the laws of the state of Minnesota.” Architects, engineers, landscape architects and certified interior designers certify a plan, specification or report; geologists and soil scientists certify a plan, document or report. Second, Minn. R. 1800.4200, subp. 4a, item B requires legal descriptions prepared by a land surveyor to be signed and certified, which is a duty the other credentials do not carry. The optional seal itself bears only your name and the legend, with no number.
Size and shape
Not addressed. No dimension appears in Minn. Stat. § 326.12, subd. 2 or in Minn. R. 1800.4300, and the board publishes none. Checked the full text of both provisions and of Minn. R. 1800.4200. There is no legally required Minnesota surveyor seal size or shape, because there is no legally required seal.
Embosser, rubber stamp or digital
For the optional seal the statute allows a regular seal or a rubber stamp facsimile “on tracings from which prints are to be made or on papers which would be damaged by the regular seal.” For the mandatory certification, Minn. R. 1800.4200, subp. 1 permits electronic, facsimile or digital form. The practical Minnesota surveying purchase is a certification block stamp carrying the prescribed survey wording, sized to fit a plat certificate area.
Signing and dating
The signature must be accompanied by the certification, your license number and the date the signature was affixed. Placement: the certification and signature “must appear on all pages of plans and drawings that must be signed, but only on the first page of specifications, plats, reports, or other documents that must be signed.” A plat therefore takes the certification on its first page rather than on every sheet, which is the opposite of the drawings rule. Nothing requires signing across a seal. Once made, the certification is permanent and “must not be removed at a later date for any reason.”
A legal description you write is a document that has to be certified
Minnesota surveyors carry two duties no other credential on this board carries. Minn. R. 1800.4200, subp. 4a, item B makes legal descriptions prepared by a land surveyor one of the named categories that must be signed and certified. A metes and bounds description emailed to a title company is not correspondence in Minnesota; it is a certifiable document. Separately, Minn. Stat. § 326.03, subd. 3 bars the filing of any plat, map or drawing of a survey or subdivision required to be recorded unless it bears a licensed land surveyor’s certification, which makes your certification the gate on the county recorder’s desk.
Against that, the seal itself is optional. Minn. R. 1800.4300 says a licensee may obtain one, and the round device is legally decorative. The operative item is a block of prescribed text, and yours is not the engineer’s. Subpart 4 gives the surveyor sentence as “I hereby certify that this survey, plan, or report was prepared by me or under my direct supervision and that I am a duly Licensed Land Surveyor under the laws of the state of Minnesota.” Survey, plan or report. A stamp that says plan, specification or report is an architect and engineer stamp with your title pasted on.
Placement also differs from drawings. The certification goes on every page of plans and drawings, but only on the first page of plats and reports.
Which documents must be sealed
Surveys, plans, plats, reports and other documents prepared under Minn. Stat. §§ 326.02 to 326.15. Minn. R. 1800.4200, subp. 4a names three categories that must be signed and certified: the certification page of each report, legal descriptions prepared by a land surveyor, and other documents requiring a signature under Minn. Stat. § 326.12, subd. 3. The statutory carve-out covers documents of an intraoffice or intracompany nature and drafts or preliminary, schematic or design development work. Recording is gated separately: no plat, map or drawing of any survey or subdivision required to be recorded may be filed unless it bears a licensed land surveyor’s certification.
Electronic and digital seals
Minn. R. 1800.4200, subp. 1 permits the certification and signature to be “electronic, as defined by Minnesota Statutes, section 325L.02, paragraph (h); facsimile; or digital.” The reference is to the Uniform Electronic Transactions Act definition, not to a surveying-specific standard. No certificate authority, algorithm or tamper-evidence test is named. The one hard limit is that a stamp, printed signature or electronically created signature carries the force of an actual signature only if it accurately depicts your actual signature.
Renewal, lapse and retirement
Use of a seal is confined to the life of an unrevoked, unexpired and unsuspended license, and stamping after expiration, revocation or suspension is unlawful unless the license has been renewed or reissued. Licenses renew biennially and the license number does not change. Nothing requires the device to be surrendered or destroyed. Recorded plats carrying your certification are permanent by their nature and by Minn. R. 1800.4200, subp. 5.
Firm requirements
Minnesota registers firms that offer land surveying services, and the board issues a Firm Registration certificate. Professional firm status under Minn. Stat. ch. 319B is a separate election requiring a Secretary of State filing. No rule requires a firm registration number on a certified plat or survey, and the firm holds no seal; the certification names you personally.
What to check before you order
Buy a certification block stamp, not a round seal. Give the supplier the land surveyor sentence from Minn. R. 1800.4200, subp. 4 in full and check the proof for the words “this survey, plan, or report,” because a supplier working from an engineer template will set “this plan, specification, or report” instead. Add ruled lines for Signature, Typed or Printed Name, Date and Lic. No. Size the block to the certificate area of the plat forms your county recorder accepts, since Minnesota itself sets no dimension. If you want the optional seal as well, it takes your name and the legend “licensed land surveyor” and no number. Keep the signature line clear, because a stamped signature counts only if it accurately depicts your own.

Frequently asked questions
Does Minnesota require a land surveyor seal?
No. Minn. R. 1800.4300 makes the seal permissive: a licensee may obtain one, and the stamped seal may be used in addition to the required certification. The mandatory item is the certification and signature under Minn. R. 1800.4200, subp. 1. Recording is gated separately, and by the certification rather than by a seal: Minn. Stat. § 326.03, subd. 3 bars any plat, map or drawing of a survey or subdivision required to be recorded from being filed unless it bears a licensed land surveyor’s certification.
What does the Minnesota certification block have to say?
The land surveyor wording from Minn. R. 1800.4200, subp. 4: “I hereby certify that this survey, plan, or report was prepared by me or under my direct supervision and that I am a duly Licensed Land Surveyor under the laws of the state of Minnesota.” Around it go your signature, your typed or printed name, the date and your license number. Check a supplier’s proof for the words “this survey, plan, or report,” because an engineer template sets “this plan, specification, or report” instead.
What goes on the optional Minnesota seal?
Your name and the legend “licensed land surveyor.” No number. Beyond that, nothing is prescribed, so the optional device is a matter of taste rather than compliance. Put your own name and any credential you actually hold, and leave off titles the state has not issued you.
What size is a Minnesota land surveyor seal?
No dimension appears in Minn. Stat. § 326.12, subd. 2 or in Minn. R. 1800.4300, and the board publishes none. There is no legally required Minnesota surveyor seal size or shape, because there is no legally required seal. Size the certification block to the certificate area of the plat forms your county recorder accepts.
Which Minnesota documents need a certification?
Surveys, plans, plats, reports and other documents prepared under Minn. Stat. §§ 326.02 to 326.15. Minn. R. 1800.4200, subp. 4a names three categories that must be signed and certified: the certification page of each report, legal descriptions prepared by a land surveyor, and other documents requiring a signature under Minn. Stat. § 326.12, subd. 3. The statutory carve-out covers documents of an intraoffice or intracompany nature and drafts or preliminary, schematic or design development work.
Does a legal description need certifying in Minnesota?
Yes, and this duty belongs to surveyors alone on this board. Minn. R. 1800.4200, subp. 4a, item B makes legal descriptions prepared by a land surveyor one of the named categories that must be signed and certified. A metes and bounds description emailed to a title company is not correspondence in Minnesota; it is a certifiable document.
Where does the certification go on a Minnesota plat?
On the first page only. The certification and signature “must appear on all pages of plans and drawings that must be signed, but only on the first page of specifications, plats, reports, or other documents that must be signed.” That is the opposite of the drawings rule, so a plat takes one certification rather than one per sheet. Once made, the certification is permanent and “must not be removed at a later date for any reason.”
What has to accompany the signature in Minnesota?
Your license number and the date the signature was affixed, along with the certification itself, under Minn. Stat. § 326.12, subd. 3. Nothing requires signing across a seal.
Can I certify electronically in Minnesota?
Yes. Minn. R. 1800.4200, subp. 1 permits the certification and signature to be “electronic, as defined by Minnesota Statutes, section 325L.02, paragraph (h); facsimile; or digital.” The reference is to the Uniform Electronic Transactions Act definition rather than a surveying-specific standard, and no certificate authority, algorithm or tamper-evidence test is named. The one hard limit is that a stamp, printed signature or electronically created signature carries the force of an actual signature only if it accurately depicts your actual signature.
What happens to my Minnesota seal or block if the license lapses?
Use of a seal is confined to the life of an unrevoked, unexpired and unsuspended license, and stamping after expiration, revocation or suspension is unlawful unless the license has been renewed or reissued. Licenses renew biennially and the license number does not change, so nothing needs recutting on renewal. Nothing requires the device to be surrendered or destroyed. Recorded plats carrying your certification are permanent by their nature and by Minn. R. 1800.4200, subp. 5.
Does a Minnesota surveying firm need a seal?
No. Minnesota registers firms that offer land surveying services and the board issues a Firm Registration certificate, and professional firm status under Minn. Stat. ch. 319B is a separate election requiring a Secretary of State filing. No rule requires a firm registration number on a certified plat or survey, and the firm holds no seal. The certification names you personally.
