A Massachusetts land surveyor seal is circular, roughly one and one half inches across, and carries four items. 250 CMR 5.03(1) names the Commonwealth, your registered name, your registration number and your professional legend. The rule then fixes where your signature goes: beside the impression, never on top of it. This page covers the face, the device options, the signing rule and what gets sealed.

What must a Massachusetts land surveyor seal show?
Four items, set by 250 CMR 5.03(1). There is no date, no expiration and no firm name among them, which keeps the face stable for the life of your registration.
- The words Commonwealth of Massachusetts
- Your name, as it appears on your registration
- Your registration number
- The legend Professional Land Surveyor
Your name has to match the register, not your letterhead. A middle initial you dropped years ago in correspondence still belongs on the die if it is part of your registered name. The Massachusetts land surveyor seal explained line by line works through the wording in more detail.
How big is the seal, and what shape?
Circular, and 250 CMR 5.03 puts the outside diameter of the depicted image at approximately one and one half inches. The word approximately gives a small tolerance, not a license to order a two inch die.
The same measurement applies to both professions this board registers, so an engineer and a surveyor in the same office work from one figure. Size the device with the signature in mind, since the rule expects clear space beside the impression rather than over it.
Which devices does 250 CMR 5.03 allow?
Massachusetts is unusually open here. The rule describes a symbol or image taking the form of a rubber stamp, an embossed seal or a digitized seal, which it defines as a computer generated image, and it leaves room for another form the Board approves.
All three named formats are lawful, so the choice is practical rather than legal. A surveyor producing long plan sets is applying the seal many times over, and an inked or self inking stamp handles that volume better than a hand press. Proper use of a Massachusetts land surveyor stamp covers the day to day handling.
Where does the signature go?
Beside the seal, and not over it. 250 CMR 5.03(6) puts the signature adjacent to the impression and requires that it does not obscure the seal, which runs opposite to the states that ask you to sign through the device.
Practically, that shapes your layout before it shapes your die. Leave room next to the impression for a signature and a date rather than sizing the block so tightly that they have to overlap.
Does Massachusetts accept a digital signature?
Yes. Section 5.03(6) accepts two forms: a legible hand written signature, or a digital signature that is properly encrypted. Either one sits beside the seal without obscuring it, on a document that is appropriately dated and signed.
The placement rule does not soften because the signature is digital. A signature dropped over the impression in a file has the same defect it would have in ink, and it is easier to catch that in a template than on a filed sheet.
Which documents carry the seal, and how many sheets?
Instruments of service that are filed with public authorities, taken sheet by sheet. The provisions cited on this point are 250 CMR 5.03(3) and (5) together with 250 CMR 5.04.
Sheet by sheet is the part that drives the practical decision. On a plan set of any size the seal is applied dozens of times, which is an argument for a device built for repetition and for ordering a spare before a filing deadline rather than after one. A guide to the wider Massachusetts land surveyor regulations puts that duty in context.
How does the board treat electronic seals?
250 CMR 5.03(11) is the operative provision, and it sets a standard by function rather than by product. No software, vendor or file format is named in it.
That makes it durable and it makes it your responsibility. Nothing on a product page can make a system compliant, because compliance is measured against what the provision requires the process to do, read together with the signature rule in 250 CMR 5.03(6).
When does registration expire?
Certificates expire on June 30 of even numbered years, under M.G.L. c. 112, §§ 81N and 81P. That is a fixed calendar date rather than an anniversary of your own registration.
Nothing on the face of the seal tracks that date, since the four required items do not include an expiration. Use of the seal after a lapse is not addressed in the rules cited here. How clients identify a registered Massachusetts land surveyor is a useful read on the registration side.
What do you need ready to order?
Your name exactly as registered and your registration number, both taken from your certificate rather than from memory. Those two lines are where ordering errors happen, and both print on the face.
Then decide the format. Filed work argues for a stamp; an embossed seal is equally lawful and is often kept for originals retained in the office. A longer guide to Massachusetts land surveyor stamps compares the formats side by side.
How do you check the impression before filing?
Take a test impression on your plan stock, then measure the outside diameter and confirm it sits at approximately one and one half inches. Read all four items against your certificate, digit by digit on the number.
Then place a signature and a date next to it exactly as you would on a filed sheet. If either one crowds the impression, the block needs redrawing before the set goes out rather than after a reviewer flags it.
Frequently asked questions
Can I sign across the seal the way I do in another state?
No. 250 CMR 5.03(6) places the signature adjacent to the impression and requires that it not obscure the seal, so signing through it is the opposite of what the rule asks for.
Does a single signed cover sheet carry a whole plan set?
The rule works sheet by sheet for instruments of service filed with public authorities. The cited provisions describe that per sheet treatment rather than a cover sheet practice.
Is an embossed seal acceptable for filed work?
An embossed seal is one of the named forms, so it is lawful. Whether it suits filed work is a durability and legibility question rather than a compliance one.
Does an expiration date belong on the face?
No. 250 CMR 5.03(1) names four items and an expiration date is not among them. Certificates expire on June 30 of even numbered years, and that date lives in your registration rather than on the die.
Do engineers on this board use a different size?
The same diameter figure applies across both professions the board registers. What differs is the legend on the face rather than the geometry of the device.
Will a particular software product satisfy the electronic seal rule?
250 CMR 5.03(11) names no product. It sets out what the process has to accomplish, so the answer depends on the process you use rather than on a brand.
Take your registered name and number straight off your certificate, decide between a stamp and an embosser for the work you file, then order from the Massachusetts land surveyor stamps and seals collection.
