Nevada does not require a public weighmaster to have a seal or a stamp. We read NRS Chapter 582 in full, every section from 582.001 to 582.320, and NAC Chapter 582 alongside it. The words seal, sealed, stamp and impression appear nowhere in the statute, and seal and stamp appear nowhere in the regulation. What Nevada requires on a certificate of weights and measures is an identification block and a signature: NRS 582.085 calls for the name and license number of the public weighmaster among the certificate contents and for “the signature of the public weighmaster who determined the weight, measure or count”, and NAC 582.060(5) requires the weighmaster or deputy weighmaster to sign “with his or her complete name”.
The most useful fact on this page for anyone about to spend money is not about a device at all. NAC 582.060(1) provides that the form of a public weighmaster certificate “must be submitted by a public weighmaster to the State Sealer of Measurement Standards for approval before the printing of a supply of certificates”. Nevada controls the paper, not the mark. Print a run of certificates to a layout nobody approved and you have a box of stock with a problem in it. Send the layout first.
Nevada public weighmaster seal requirements at a glance
| Requirement | Nevada rule | Source |
|---|---|---|
| Seal required | No. Not addressed anywhere. The words seal, sealed, stamp and impression do not appear in NRS Chapter 582, and seal and stamp do not appear in NAC Chapter 582. A certificate of weights and measures “when properly filled out and signed, is prima facie evidence of the accuracy of the measurements shown”. Signed, not sealed. | NRS ch. 582; NAC ch. 582; NRS 582.085 |
| Required elements | No seal, so no seal elements. The identification NRS 582.085 puts on the certificate is the name and license number of the public weighmaster, together with the signature of the weighmaster who determined the weight, measure or count. | NRS 582.085 |
| Size and shape | Not addressed. No seal exists in the statute or the regulation, so no diameter, dimension or shape is published anywhere in NRS or NAC Chapter 582. Do not infer one from a neighboring state or from a product listing. | NRS ch. 582; NAC ch. 582 |
| Device allowed | Not addressed for any seal. What Nevada does control is the certificate form: NAC 582.060(1) requires it to be submitted to the State Sealer of Measurement Standards for approval before a supply of certificates is printed. | NAC 582.060(1) |
| Signature and date | Both required. NRS 582.085 requires the signature of the public weighmaster who determined the weight, measure or count, and requires the date of issue and the certificate number among the contents. NAC 582.060(5): “The weighmaster or deputy weighmaster shall sign the certificate with his or her complete name.” | NRS 582.085; NAC 582.060(5) |
| What must be sealed | Nothing. What must be signed and completed is the certificate of weights and measures. NAC 582.060(4) adds that all information recorded must be neat, clear and complete. | NRS 582.085; NAC 582.060(4) |
| Electronic seal | Not addressed. No electronic seal or digital signature provision appears anywhere in NRS Chapter 582 or NAC Chapter 582. There is no electronic version of a device the state never required. | NRS ch. 582; NAC ch. 582 |
| Renewal and lapse | Nothing is surrendered on lapse, because no seal is issued. NRS 582.040 covers issuance and fee, 582.047 requires a renewal application to include state business license information, 582.045 covers suspension for failure to pay child support and 582.049 sets grounds for suspension or revocation. NRS 582.021(4) directs the State Sealer to adopt regulations on qualifications, renewal, validity periods, measurement practices, required certificate information and record-keeping periods. | NRS 582.021(4), 582.040, 582.045, 582.047, 582.049 |
| Firm requirements | Not addressed as an entity credential. The controlled item is the certificate form, which must be pre-approved before a supply is printed. NRS 582.115 requires a public weighmaster to keep and preserve a legible copy of each certificate issued, for the period the State Sealer specifies by regulation. | NAC 582.060(1); NRS 582.115 |
| Regulator | State Sealer of Measurement Standards, within the Nevada State Department of Agriculture. This is not a professional board. The word Sealer in that title refers to the officer who seals weighing devices, and it is not the source of any weighmaster seal. | NRS 582.004, 582.028 |
Does Nevada require a public weighmaster seal?
No. This one was checked directly rather than inferred. Every section heading in NRS Chapter 582 was read, from 582.001 through 582.320, and NAC Chapter 582 was read alongside it. The words seal, sealed, stamp and impression appear nowhere in the statutory chapter, and seal and stamp appear nowhere in the regulation.
What Nevada uses instead is set out in NRS 582.085: a certificate of weights and measures, “when properly filled out and signed, is prima facie evidence of the accuracy of the measurements shown”. Filled out and signed. That is the whole authentication, and the certificate’s legal effect turns on it rather than on any mark pressed or printed onto the page.
That is a finding rather than an absence of evidence, and it is worth stating that way because the opposite claim is easy to make. Nevada has a weighmaster chapter, a licensing officer, a prescribed certificate and an offence of simulating one. Everything about the structure looks like a state that would require a seal. It simply does not, and the place where the authentication lives is the signature line.
The State Sealer seals scales, not certificates
Nevada is the easiest state in this group to get wrong, because the regulator’s title contains the word that people search for. The licensing official is the State Sealer of Measurement Standards, and NRS 582.028 provides that, except as otherwise provided in NRS 582.029, to act as a public weighmaster a person must receive a license from that officer.
That office seals weighing and measuring devices. It is the weights and measures function of testing a scale and marking it as approved. It is a different thing from a practitioner’s seal on a document, it imposes no marking duty on a weighmaster’s paperwork, and it should never be reported as a weighmaster seal requirement. A page that reads the job title and concludes Nevada weighmasters need seals has made exactly that mistake.
What a Nevada certificate of weights and measures must contain
NRS 582.085 sets the list, and it is the substance of this page. The certificate includes the name and license number of the public weighmaster; the kind of commodity weighed, measured or counted; the name of the owner, agent or consignee of the commodity; the name of the recipient where applicable; the date of issue and the certificate number; identification of the carrier or vehicle; information distinguishing the commodity; the count of units where applicable; the measure of the commodity where applicable; the weight or mass data including gross weight, tare weight or both; and the signature of the public weighmaster who determined the weight, measure or count.
The first and last items together are the Nevada equivalent of what other states put on a seal. A name, a license number and a signature, on the face of the certificate. If you have been thinking about a device, think about that block instead, because it is the thing the statute names.
The form has to be approved before you print
NAC 582.060(1) is the rule most likely to cost a Nevada operator money if it is missed: “The form of a public weighmaster certificate must be submitted by a public weighmaster to the State Sealer of Measurement Standards for approval before the printing of a supply of certificates.”
Before the printing, and of a supply. That puts the approval step ahead of the print run rather than ahead of first use, which is the sequence to follow when you are changing a layout, adding a yard, rebranding or switching printers. NAC 582.060(2) adds that the certificate must contain all information applicable to the transaction, which is the content test the approved form has to satisfy.
Sign with your complete name
NAC 582.060(5) is short and specific: “The weighmaster or deputy weighmaster shall sign the certificate with his or her complete name.” Complete name, not initials, and not a mark. NRS 582.085 pairs that with the requirement for the signature of the weighmaster who determined the weight, measure or count, which ties the signature to the person who did the work rather than to whoever is at the counter.
NAC 582.060(4) sets the legibility standard for everything else on the page: all information recorded must be neat, clear and complete. On a multi-part carbonless ticket that is a real consideration, and it is the practical reason a printed name block beside the signature line is worth having even though Nevada does not require a device to produce one.
Gross only, tare only, and unused spaces
NAC 582.060(3) handles the partial weighing case, and it gives three ways to do it. When issuing a certificate for gross weight only or tare weight only, the words “gross only” may be entered in the space provided for recording the tare weight, the words “tare only” may be entered in the space provided for recording the gross weight, or all unused spaces must be deleted by drawing a line through them.
The reason behind that rule is the same one behind the seal rules in other states. A blank space on a weight certificate is an invitation for someone else to fill it in later, and the regulation closes it either by labeling it or by striking it out. It is worth building into the scale house routine rather than leaving it to whoever is on shift.
Identifying the vehicle, including the ones without plates
NAC 582.060(6) requires the vehicle license number to be recorded in the proper space on the form. Subsection (7) covers a vehicle weighed for licensing purposes: the words “for licensing” must be written in the space provided for license numbers. Subsection (8) covers equipment with no plate: a vehicle or other equipment that does not display a license plate must be identified by other means, such as an equipment number or a description.
Read those with NRS 582.085, which requires identification of the carrier or vehicle among the certificate contents, and NRS 582.210, which governs weighing a vehicle or a combination of vehicles. Nevada wants the certificate to point unambiguously at a physical thing that was on the scale.
Licensing, exemptions and who may issue
NRS 582.012 defines a public weighmaster as any person who performs public weighing. NRS 582.028 requires a license from the State Sealer of Measurement Standards to act as one, except as otherwise provided in NRS 582.029, which is headed “Exemption from licensure; issuance of certificate of weights and measures prohibited without license”.
That heading carries the sting. An exemption from licensure is not an authority to issue certificates: 582.029 prohibits issuing a certificate of weights and measures without a license. NRS 582.040 covers issuance and the fee, and 582.047 requires a renewal application to include state business license information.
Records, and the prohibited acts
NRS 582.115 requires a public weighmaster to keep and preserve a legible copy of each certificate of weights and measures issued, for the period the State Sealer specifies by regulation. NRS 582.021(4) is the source of that regulatory power, directing the State Sealer to adopt regulations on qualifications, renewal requirements, validity periods, measurement practices, required certificate information and record-keeping periods.
NRS 582.300 lists prohibited acts and carries a civil penalty. Among them are acting as a public weighmaster without a valid license, falsifying a certificate of weights and measures or falsely certifying any gross, tare or net weight, and issuing “a certificate simulating the certificate of weights and measures issued” by a licensed public weighmaster. NRS 582.310 covers civil penalties, appeal and recovery, and NRS 582.320 covers criminal penalties.
That simulation provision is worth a moment. In a state with no seal, the thing being protected from imitation is the approved certificate form itself, which is why NAC 582.060(1) sends the form to the State Sealer before it is printed.
Nevada compared with the states that do require a seal
Operators who hold appointments in more than one state get caught by assuming the requirements travel. They do not, and the contrast is sharp. Maine requires a licensed public weighmaster to procure an impression seal at the weighmaster’s own expense, with the wording fixed by statute and no electronic alternative anywhere in the subchapter. Mississippi requires a bonded weighmaster to do the same, reading the licensee’s name plus Mississippi on the margin and Bonded Weighmaster in the center, while permitting an electronic alternative carrying the name and number. New Jersey requires a seal whose center reads public weigher even though the appointment is styled Certified Weighmaster. Arizona issues the device itself, keeps title to it and takes it back within thirty days of a weighmaster ceasing to operate.
None of that reaches a Nevada licensee, and a Nevada license satisfies none of it. If you weigh across a state line, the requirement that applies is the one for the state where the weighing happens and the certificate is issued. The reverse trap matters too: a weighmaster who holds a Maine or New Jersey seal and starts weighing in Nevada does not need to use it here, and impressing an out of state seal on a Nevada certificate of weights and measures adds a mark the approved form does not contemplate.
What a Nevada weighmaster might actually buy
Since no seal is prescribed, anything you buy is a convenience and we will not pretend otherwise. Two things have a real job. The first is the approved certificate stock, and the approval step comes before the print run. The second is a plain text stamp setting your name and license number, which is the block NRS 582.085 puts on the certificate.
A stamp earns its place where the block has to go on something that did not come off the approved stock: a file copy, a worksheet, a delivery ticket. It also helps with the neat, clear and complete standard in NAC 582.060(4), since a pressed block reads better on the third sheet of a carbonless set than a handwritten one. We make text stamps to order in the custom made rubber stamps and custom self inking stamps ranges. What we will not do is sell you a round die reading Nevada public weighmaster and let it look like compliance, because Nevada asks for no such thing. Note too that the signature itself is yours to write: NAC 582.060(5) asks for a complete name signed by the weighmaster, so a facsimile signature stamp is not a substitute for signing.
What we did not read
One item, and it does not change the answer. The Nevada Department of Agriculture publishes a public weighmaster information PDF that we did not read. It is program guidance rather than law, and the statute and the regulation, both read in full, are unambiguous that no seal is prescribed.
If your question is about program practice rather than about the rule, for example how the State Sealer prefers a certificate form to be submitted for approval, that guidance and the office itself are the right place to ask.

Frequently asked questions
Does Nevada require a public weighmaster seal?
No. The words seal, sealed, stamp and impression appear nowhere in NRS Chapter 582, and seal and stamp appear nowhere in NAC Chapter 582. NRS 582.085 makes a certificate of weights and measures prima facie evidence when properly filled out and signed.
The regulator is called the State Sealer. Does that not mean there is a seal?
Not a weighmaster seal. The State Sealer of Measurement Standards is the officer who seals weighing and measuring devices, meaning the scale itself after testing. That is a different mark on a different thing, and it imposes no marking duty on your certificates.
What has to be on a Nevada certificate of weights and measures?
NRS 582.085 lists the name and license number of the public weighmaster; the kind of commodity; the name of the owner, agent or consignee; the name of the recipient where applicable; the date of issue and the certificate number; identification of the carrier or vehicle; distinguishing information; the count of units where applicable; the measure where applicable; weight or mass data including gross, tare or both; and the signature of the weighmaster who determined the weight, measure or count.
Do I need approval before printing certificates?
Yes. NAC 582.060(1) requires the form of a public weighmaster certificate to be submitted to the State Sealer of Measurement Standards for approval before the printing of a supply of certificates. Do that before the print run, not before first use.
Can I use a signature stamp?
NAC 582.060(5) requires the weighmaster or deputy weighmaster to sign the certificate with his or her complete name, and NRS 582.085 ties the signature to the weighmaster who determined the weight. Nothing in the chapter authorizes a facsimile signature, so treat signing as something you do by hand.
Is there an electronic seal for Nevada weighmasters?
No. No electronic seal or digital signature provision appears in NRS Chapter 582 or NAC Chapter 582, and there is no physical seal either, so the question does not arise.
What size is a Nevada weighmaster seal?
There is none, so no size is published and none should be inferred. A diameter quoted to you for Nevada has come from another state or from a product listing rather than from Nevada law.
What happens if someone issues a lookalike certificate?
NRS 582.300 prohibits it. The prohibited acts include acting as a public weighmaster without a valid license, falsifying a certificate or falsely certifying any gross, tare or net weight, and issuing a certificate simulating the certificate of weights and measures issued by a licensed public weighmaster. NRS 582.310 and 582.320 cover civil and criminal penalties.
