National Register plaques: rules, wording, who can buy one

John HarrisonUpdated October 2026

There is no official National Register plaque. The National Park Service, which keeps the Register, does not issue or sell plaques when a property is listed, does not require one, and sets no rules for design or wording. Owners who want a plaque buy one from a private foundry, using wording the NPS suggests and any style their state office prefers.

This page explains what the NPS actually says, how the standard wording came about, which states run their own plaque or sign programs, and what to check before ordering. Prices and programs are stated as of October 2026. nationalhistoricalregister.com is an independent reference site with no connection to the NPS, any State Historic Preservation Office (SHPO) or any plaque maker.

What the NPS says, in its own words

The NPS National Register FAQ page answers the plaque question directly. Three points matter:

The same page lists roughly 35 private companies that advertise plaques in Preservation Magazine. The NPS says the list is not an endorsement and not exhaustive. Several SHPOs reproduce it, and the NCSHPO member pages carry a standing notice that state preservation staff, as government employees, cannot endorse or recommend any vendor.

The standard wording

The NPS sample for an individually listed property is:

This property has been listed in the National Register of Historic Places by the United States Department of the Interior.

For a contributing building in a district the sample names the district, in the form “This property is part of the [name] Historic District, listed in the National Register of Historic Places by the United States Department of the Interior.”

State offices build on this:

Practical reading: “listed in” is the correct verb, the Department of the Interior is the listing authority, and the year built and year listed are the most common additions. Verify the historic name and listing date on the property’s page before you sign off a proof; the name in the nomination is often not the name on the mailbox. The address lookup finds the entry.

Who may buy one

Anyone who owns a listed property, individually listed or contributing to a listed district. Foundries do not check listing status, so the responsibility for accuracy is the owner’s. A plaque on a non-contributing building in a district, or on a property that was only determined eligible, misstates the record.

Nothing in the NPS material restricts plaques to private owners. Public buildings such as the Hall County Courthouse in Texas, churches such as Old North Church in Boston, and house museums such as Monticello are all listed properties whose stewards may mark them if they choose.

State and local programs that do exist

Most SHPOs only publish vendor lists. A few go further:

State or bodyWhat it offers (as of October 2026)
Montana Historical SocietySells National Register signs: pewter-finished anodized aluminum with etched black lettering. Type A, 20 x 24 in, for an individually listed property or district overview, $55; Type B, 13 x 16 in, for a contributing property, $35; post mount $7 extra. Text is drafted by staff from the nomination (250 or 185 words) and approved by the owner; delivery eight to ten weeks after approval.
Connecticut SHPOA subsidised aluminum plaque, about 4 x 7 in, $50, for State Register and National Register properties. The program is suspended until further notice because manufacturing costs rose.
Georgia Historic Preservation DivisionEncourages plaques but neither requires nor supplies them; lists three foundries as a public service (revised October 2025).
Washington DAHPDoes not provide plaques “at this time”. Notes that the William G. Pomeroy Foundation funds free National Register markers, including pole and shipping, for public agencies and 501(c)(3) nonprofits but not private residences or businesses.
California OHPNo requirement, no recommended maker; publishes a vendor list and the “listed in” wording note.
Prince George’s County, MarylandA county program, not a National Register one: cast bronze oval plaques, about 7 x 10 in, for designated county Historic Sites; full cost $200, owner pays $100; the commission retains control of the plaque and can remove it if alterations diminish integrity.

Local programs like the Maryland example mark local designation, which is a different status from National Register listing. See local landmark vs National Register vs National Historic Landmark before you order a plaque that claims the wrong one.

Before you order

  1. Confirm the listing. Find the entry, its reference number and listing date. The site’s property pages carry all three and link the nomination.
  2. Ask the SHPO. The NPS tells owners to do this, and some offices have a preferred style. The SHPO directory has every office’s website.
  3. Check local rules. The NPS FAQ reminds owners that state or local preservation laws may apply even though federal listing imposes none. In a locally designated district, attaching anything to a façade may need a certificate of appropriateness. A Hendersonville, North Carolina commission, for example, states that contributing buildings in its districts are eligible to place a marker and lists vendors; others require approval of the mounting method.
  4. Choose material and maker. Cast bronze, cast aluminum and etched metal differ in cost, weight and upkeep; see bronze vs aluminum vs cast plaques and the plaque vendor comparison.
  5. Plan the mounting. Drilling brick or stone is the one way a plaque can damage a listed building. Mounting a plaque on historic fabric covers mortar-joint drilling, reversible fixings and post mounts.

What a plaque does not do

A plaque confers nothing. Listing itself places no restrictions on what a non-federal owner may do with the property unless federal assistance, licensing or permitting is involved, and a plaque does not change that either way. It does not trigger review, protect the building from demolition, or qualify it for tax credits; see what listing means for homeowners. What it does is state a fact about the building, which is why the wording should be accurate and the mounting should be reversible.

Frequently asked questions

Does the National Park Service send a plaque when a property is listed?

No. The NPS National Register FAQ says the Register does not issue plaques as a result of listing and leaves it to owners to decide whether they want one. Listing does not require a plaque.

Is there an official National Register plaque design?

No. The NPS has no formal requirements or suggestions for plaque design or wording. It offers two sample sentences and recommends asking your State Historic Preservation Office whether it has a preferred style.

What should a National Register plaque say?

The NPS sample reads: 'This property has been listed in the National Register of Historic Places by the United States Department of the Interior.' Several SHPOs add the historic name, year built and year listed. California's office asks owners to use 'listed in', not 'placed on'.

Can I put up a plaque for a house in a historic district?

Yes, if the house is a contributing property. The NPS sample wording for districts names the district: 'This property is part of the [name] Historic District, listed in the National Register of Historic Places by the United States Department of the Interior.' Check your SHPO's wording and any local commission rules first.

Do any states supply plaques?

A few run programs. As of October 2026, Montana sells etched aluminum National Register signs ($35 to $62), Connecticut's $50 aluminum plaque program is suspended, and Georgia, Washington and California say they neither require nor supply plaques. Most states only publish vendor lists.

Is this site connected to the National Register?

No. nationalhistoricalregister.com is an independent guide. The National Register is kept by the National Park Service; nominations go through State Historic Preservation Offices. We sell nothing and have no affiliate relationships with plaque makers.
