Idaho puts four items on an architect seal and gives no dimension. Section 54-304(1) names your name, your Idaho architect license number and two legends, then stops short of any diameter, outline or device. Subsection (2) ties the signature and the date to the seal, and allows all three to be applied by hand or electronically. This page covers the face, the silences and what to settle before ordering.

Idaho is one row in our architect seal requirements by state table, which sets each jurisdiction's rule side by side. Still working toward the license? The architect licensing path by state sets out what Idaho asks for first.
What has to appear on an Idaho architect seal?
Four items, all of them statutory. Section 54-304(1) sets them out directly rather than handing the design to a board, so the face is fixed by the code itself.
- Your name, as licensed
- Your Idaho architect license number
- The words state of Idaho
- The words licensed architect
The exact vocabulary matters. Idaho uses licensed rather than registered, and it treats the state legend as a separate element from the number rather than as a suffix to it. A fuller reading of Idaho architectural seal requirements works through that wording point by point.
Do the signature and date travel with the seal?
Yes. Under section 54-304(2) the signature, the date and the seal appear together on technical submissions the architect prepared, or that meet what subsection (4) sets out. The three are named as a set rather than as a seal plus two optional extras.
That makes a dated, signed and sealed sheet the unit Idaho recognizes. A submission carrying a clean impression and no date is missing one of the three things the subsection names, which is worth building into your title block rather than leaving to habit.
What size must an Idaho architect stamp be?
Idaho sets no size. Section 54-304 prescribes no diameter, no shape and no proportion, and there is no dimensioned artwork behind the statute to work back from.
So any figure quoted as an Idaho standard diameter is a trade convention rather than a rule. Size the device for legibility on the submissions you actually issue, which in practice means large enough that the license number survives a reduction or a copy. Choosing a size for an Idaho architect stamp covers how that decision usually goes.
Which device may be used?
Not addressed. The statute regulates application rather than the device, so it does not tell you whether the impression comes from an ink stamp, a press or an image placed in a file.
Read that as an open choice rather than as a gap you have to fill defensively. Nothing in the chapter names a preferred format, and nothing conditions compliance on one. Design options for an Idaho architect stamp compares the formats architects here tend to use.
Can the seal be applied electronically?
Section 54-304(2) allows the signature, the date and the seal to be applied manually or electronically. What it does not do is build a system around that permission: Idaho names no technology and sets up no approval process.
The practical effect is that an electronically applied seal stands or falls on ordinary evidence rather than on a prescribed certificate scheme. There is no state approved product to look for, because the statute creates none.
What do the board rules add?
Nothing on the seal. IDAPA 24.01.01, which holds the Board of Architects and Landscape Architects rules, carries no seal provision, so the statute is the whole of the requirement.
That is unusual enough to be worth stating plainly. In most states the design detail lives in an administrative rule and the statute only authorizes it. In Idaho there is one place to look, and section 54-304 is it.
Which documents does the seal go on?
Every technical submission issued from the architect's office. Subsections (3) through (6) are the provisions cited for that scope, and they reach submissions the architect prepared as well as those qualifying under subsection (4).
Issued from the office is the operative phrase, so the test is what leaves your practice rather than what you personally drew. How the Idaho architect stamp guidelines apply day to day is a useful companion read on that scope.
What happens when a license lapses?
The chapter is silent as to the device itself. Idaho Code § 54-312 covers renewal and reinstatement, § 54-314 covers discipline, and § 54-315 carries a misdemeanor provision, but none of them says what becomes of the seal.
So there is no surrender duty stated and no destruction duty stated. The authority to seal follows the license, and the sections just named are where the consequences of practicing without one sit. What an Idaho architect stamp does on a submission puts that relationship in context.
What should you confirm before ordering?
Your license number and the spelling of your name, both read off your license rather than typed from memory. Those two lines are where reorders come from.
Then decide the diameter yourself, since no rule decides it for you, and check that both legends are set in full. The wording is where Idaho is strict, and it is the part no size choice can rescue.
How do you check an impression before it goes on a submission?
Stamp a test sheet on the stock you issue on, then read the four items against your license. Take the number digit by digit, because a transposed pair is the error that survives a casual look.
Then reduce or copy the test sheet at the scale your submissions get handled at. If the license number or either legend closes up, order a larger face before the die goes into service, since nothing in the statute stops you from choosing one.

Frequently asked questions
Is there an official Idaho architect seal diameter?
No. Section 54-304 prescribes no diameter, and no board rule supplies one. Any figure presented as the Idaho standard is a manufacturing convention.
Should the legend say registered architect?
No. The statute names the words licensed architect, and Idaho uses licensed rather than registered throughout this provision.
Is there anything to file or approve with the board before using a seal?
Nothing in the cited sources describes a filing, an approval or a registration step. The statute names the four elements, IDAPA 24.01.01 carries no seal provision, and there is no process in between.
Does an expiration date belong on the die?
Section 54-304(1) names four elements and an expiration date is not among them. The date the statute does require is the one applied to the submission under subsection (2).
If I seal electronically, does the date still have to appear?
Yes. Subsection (2) treats the signature, the date and the seal as a set, and the manual or electronic option applies to all three rather than replacing any of them.
Does a submission drawn by staff still carry my seal?
The scope runs to technical submissions issued from the architect's office, and reaches those the architect prepared as well as those qualifying under subsection (4). The cited sources describe it in those terms.
Read your license number and name straight off your license, pick a diameter that stays legible after copying, then order from the Idaho architect stamps and seals collection.
