A Colorado landscape architect stamp must show your name, your license number, your date of licensing and the state's landscape architect legend, under C.R.S. § 12-130-116(1). The stamp, your signature and the date you sign travel together on the reproduced drawings that make up the record set. The statute sets no size and names no device. This page covers the face, signing, electronic stamps and ordering.

What must a Colorado landscape architect stamp show?
Four items, all fixed by C.R.S. § 12-130-116(1): your name, your license number, your date of licensing, and the Colorado landscape architect legend. The statute lists no fifth element for the face.
The date of licensing is the item that sets this stamp apart from a plain name and number layout. It sits inside the impression as one of the four listed items, and it is a different date from the one you write each time you sign a drawing. Our notes on Colorado landscape architect seal design show how the four items can share one face.
How does the legend have to read?
The legend is the word Colorado, followed by a hyphen, followed by Licensed Landscape Architect. C.R.S. § 12-130-116(1) gives that wording, so it goes on the stamp as the statute writes it, with no words added or dropped.
The statute fixes the words but gives no shape or size, so where the legend sits on the face is a layout decision rather than a legal one. When you review a proof, read the legend letter by letter and confirm the hyphen after Colorado is present.
How do you sign and date a stamped drawing?
Stamp, sign and date as one step. Under C.R.S. § 12-130-116(2)(a), the stamp, the signature of the landscape architect named on it and the date of that signature go on reproductions of drawings, and together they establish the record set of contract documents.
Two dates are in play on every sheet. The date of licensing is part of the stamp and stays the same from sheet to sheet, while the signature date records when you signed. The signer is the licensee whose name the stamp carries, so the stamp is not a device a colleague signs over. A closer look at Colorado landscape architect stamp requirements walks through the signing step.
Which documents does the sealing duty cover?
The record set of contract documents. C.R.S. § 12-130-116(2)(b) to (g) organizes the sealing duty around that record set, and subsection (2)(a) is what creates it: stamped, signed and dated reproductions of your drawings.
Plan your stamping around the set you will issue as the record, not around working prints. This page reports only the organizing idea of those subsections, so read them directly for how each part of the record set is treated.
What size and shape must the stamp be?
Colorado's statute sets neither. C.R.S. § 12-130-116 gives no diameter, no minimum and no shape for a landscape architect stamp, so the statute prescribes no size at all.
Size the stamp for legibility instead. The face has to hold a name, a license number, a full date and a four word legend, and all of it has to stay readable on reproduced drawings. A slightly larger face gives the date of licensing room so its digits do not crowd the number.
Which stamp devices does Colorado allow?
The statute does not say. C.R.S. § 12-130-116(3) and the rest of the section name no device type, so the statute neither lists nor rules out any particular kind of stamp.
Let the document decide. Because the stamp goes on reproductions of drawings, pick a device whose mark reads clearly on those sheets. An inked stamp leaves a visible impression that carries through when a sheet is copied or scanned. For a wider comparison, see getting your Colorado landscape architect seal.
Can you use an electronic stamp in Colorado?
Only once the board allows it by rule. C.R.S. § 12-130-116(3) gives the board power to allow stamps and seals in electronic form, along with electronic recordkeeping, provided they match the paper requirements of subsections (1) and (2) in substance.
The subsection grants a power; it does not set a standard. It does not identify a technology or set any criteria an electronic stamp must meet. Definitions of public key infrastructure and signature dynamics do exist in Rule 1.2(B) of 4 CCR 730-1, but that rule belongs to the separate board for architects, engineers and land surveyors, and subsection (3) does not carry those definitions over. An electronic landscape architect stamp therefore depends on a board rule, not on the statute alone.
What happens to your stamp if your license expires?
The stamp section itself does not address use after a lapse, but the license itself is subject to expiration. Under C.R.S. § 12-130-109(8), C.R.S. § 12-20-202(1) and (2) governs how licenses renew, expire and are reinstated, along with delinquency fees.
An expired license is not a neutral state. Its holder is exposed to the penalties in the landscape architect article or in § 12-20-202(1), as C.R.S. §§ 12-130-109(8), 12-20-202 and 12-130-119 provide. Keep the license current so that every record set you stamp is backed by an active credential. Our Colorado landscape architect stamp application guide covers the licensing side.
What should you give us when you order?
Your name as it should appear, your Colorado license number, your date of licensing, and the size and device you want. The legend is fixed by statute, so we set it exactly as C.R.S. § 12-130-116(1) gives it.
Send the date of licensing in the format you want printed and check it against your license record before you approve the proof. If you plan to sign close to the impression, mention it so the layout leaves clear space. Our overview of the Colorado professional landscape architect stamp covers the same order details from the product side.
How do you check a new impression before using it?
Stamp a test sheet, copy or scan it, and read every element on the copy: name, license number, date of licensing and the full legend with its hyphen. The copy matters because the stamp is used on reproductions.
Then sign and date next to the test impression the way you will on a record set. If your signature or the date you write covers any part of the stamp, move your signing position or choose a larger face before the first real set goes out.
Frequently asked questions
Does the Colorado stamp carry an expiration date?
No expiration date is among the four elements in C.R.S. § 12-130-116(1). The only date on the face is your date of licensing. The date you sign is added to the drawing along with the stamp and your signature.
Can I add my firm name to the stamp?
A firm name is not one of the four elements in C.R.S. § 12-130-116(1). The statute's list covers you as an individual licensee: your name, number, date of licensing and the legend.
Can an embosser be used?
The statute neither allows nor forbids one by name. Because the stamp goes on reproduced drawings, confirm that any raised mark shows clearly on those sheets before relying on it by itself.
Does each sheet get its own signature date?
The date that accompanies the stamp is the date of your signature, so it follows each act of signing. Sheets signed on different days carry different signature dates, while the date of licensing in the stamp never changes.
Has the board already authorized electronic stamps?
C.R.S. § 12-130-116(3) only grants the power. No board rule exercising it is among the sources read for this page, so treat an electronic Colorado landscape architect stamp as unconfirmed until you have seen that rule.
With your name, license number and date of licensing confirmed, choose a stamp from our Colorado stamps and seals collection and test the first impression on a copy before you stamp a record set.
