First, the easy way: PERRLA
Paste the page's URL into PERRLA's reference search. For organizations PERRLA knows, like the World Health Organization, the American Nurses Association, and the Mayo Clinic, it fills in the organization as the group author (with its abbreviation, when it has one), the title in sentence case, the date, and the URL. When the site name matches the author, PERRLA leaves it out of the reference.
Then check the result against the page. If the page has a byline, the person is the author: change the group author to an Author with their name. If the site's name came in as the author (HealthyChildren.org instead of the American Academy of Pediatrics), put the organization's name in its place. Make sure the date is the one the page shows for its content, and if the only date is a "Last reviewed" date, clear Publication Date so PERRLA prints n.d. Citing two groups with the same abbreviation, like the two AACNs? Clear the Abbrev. field on both, and PERRLA spells each name out every time.
Adding one by hand? Choose Webpage, add a Group Author (Organization), and type the organization's full name. Put its abbreviation in the Abbrev. field if you want to use it in your paper, and PERRLA spells the name out in your first citation and uses the abbreviation after that. Type the page title in sentence case (PERRLA flags a title typed in title case and offers to fix it). Fill in Website Name either way: when it's the same as the author, PERRLA leaves it out of the reference for you.

Not using PERRLA yet? Here is how to build the same reference by hand.
The parts of the reference
1. Author: the organization
On an organization's website, the organization itself is the author unless the page names a person. Write its full name exactly as the organization writes it, followed by a period. Don't abbreviate it in the reference, even if everyone knows it by its initials.
World Health Organization.
Look for a byline first. A page that says "By Rachel Y. Moon, MD, FAAP" has a person as its author, and the organization moves to the site name. Leave degrees and credentials like MD, RN, or FAAP out of the reference.
For a government agency, use the most specific agency that made the page, like the Agency for Healthcare Research and Quality, and put its parent agencies in the site name spot. The CDC and NIH guides walk through that pattern.
2. Date
Use the most specific date the page gives for its content: year, month, and day if it's there, in that order. A fact sheet dated 11 August 2026 becomes (2026, August 11).
(2026, August 11).
A "Last updated" or "Updated" date that belongs to this page counts. A "Last reviewed" date doesn't, because content that was reviewed wasn't necessarily changed. The copyright year in the footer doesn't count either: it covers the whole website, not this page. If there's no date for the page, write (n.d.).
3. Page title
Italicize the page title and write it in sentence case: capitalize the first word, the first word after a colon, and proper nouns. Organizations usually capitalize every word in their headings, so you'll lowercase most of it. Names and abbreviations stay capitalized.

4. Site name, or nothing
Give the website's name, not italicized, followed by a period. When the site name is the same as the author, leave it out, so the organization's name doesn't print twice.
World Health Organization. (2026, August 11). Nursing and midwifery. https://www.who.int/...
When the site has its own name, keep it. The American Academy of Pediatrics publishes its pages for parents on a site called HealthyChildren.org, so that name goes in the source.
HealthyChildren.org.
5. URL
End with the full URL of the page you read, not the organization's home page. Don't put a period after it.

Examples
An organization's page where the author and site name match
The World Health Organization's fact sheet on the global nursing workforce. WHO wrote it and WHO runs the site, so the site name drops out, and the date is the one printed under the title.

An organization's page on a site with its own name
A page on fever in babies from the American Academy of Pediatrics. It has no byline, so the AAP is the author, and it lives on the AAP's parent site, HealthyChildren.org, so the site name stays. The page shows "Last Updated 9/23/2025." This citation points to the section a quote came from.

A page on an organization's site with a person's byline
Another HealthyChildren.org page, but this one opens with "By: Rachel Y. Moon, MD, FAAP." A named person makes her the author. The site name stays, and her credentials don't go in the reference.

Two organizations with the same abbreviation, part 1
Nursing has a famous pair of AACNs: the American Association of Colleges of Nursing and the American Association of Critical-Care Nurses. If your paper cites both, APA says to spell both names out in every citation, so the Abbreviation field stays empty. This fact sheet ends with "Updated: October 2026."

The other AACN's page on healthy work environments. It shows no date for its content, so it takes n.d. Spelled out in full, the two citations can never be confused.

In-text citations
Cite an organization's page by the organization's name and the year, the same way you'd cite a person. Long names can be abbreviated in your text, never in the reference list.
- First parenthetical citation, with an abbreviation: (World Health Organization [WHO], 2026). The abbreviation goes in square brackets.
- After that: (WHO, 2026)
- First narrative citation: World Health Organization (WHO, 2026) estimated ... and after that, WHO (2026) reported ...
- No abbreviation: (American Association of Critical-Care Nurses, n.d.), the full name every time.
- A quote with no page numbers: name the heading the quote sits under, followed by the word section, or count the paragraphs: (AAP, 2025, What's considered a fever? section) or (AAP, 2025, para. 2). A full heading takes no quotation marks, and you can shorten a long one.
- A page with a byline: the person, not the organization: (Moon, 2026).
When to abbreviate: APA leaves it up to you. Do it when the abbreviation is well known or you'll cite the group at least three times. Introduce it only once in the whole paper, even if you cite several pages by the same group. And if two groups you cite share an abbreviation, like the two AACNs, spell both out every time.

Quick checklist
- Check for a byline: a named person is the author, not the organization
- The organization's full name, never its abbreviation, in the reference
- The page's own date or update date, or n.d.
- Page title in italics and sentence case
- Site name only when it's different from the author
- The page's full URL, no period after it
- In text: full name with [ABBR] the first time, then the abbreviation
Questions students ask
Who is the author of a webpage with no author listed?
On an organization's or agency's website, the organization is the author unless the page names a person. Check the top and bottom of the page for a byline, and the "About" page if you're unsure who runs the site. A page with truly no responsible person or group moves its title into the author spot.
Do I include the website name if it's the same as the author?
No. When the organization and the site have the same name, leave the site name out and go straight from the title to the URL. Keep it when the site has its own name, like HealthyChildren.org for the American Academy of Pediatrics.
How do I abbreviate an organization's name in APA?
Spell the name out the first time you cite it and add the abbreviation: in square brackets in a parenthetical citation, (World Health Organization [WHO], 2026), or in the parentheses with the year in a narrative one, World Health Organization (WHO, 2026). Then use the abbreviation alone. The reference list never uses it.
Do I have to abbreviate the organization's name?
No, it's optional. Abbreviate when the abbreviation is well known, saves clumsy repetition, or will appear at least three times in your paper. For a group you cite only once or twice, the full name is usually simpler.
What if two organizations have the same abbreviation?
Spell both names out in every citation. The American Association of Colleges of Nursing and the American Association of Critical-Care Nurses are both AACN, and so are the American Heart Association and the American Hospital Association (AHA). If you cite only one of a pair, you can abbreviate it.
Should I use the organization's "How to cite this page" box?
Check it against APA first. Many organizations' suggested citations follow another style, add the access date, or put the site name in twice. Use the parts it gives you, and build the reference in the order shown on this page.
What if the organization's page is a PDF?
A PDF that stands on its own, like a report, a guideline, or a policy brief with its own title, is cited as a report, not a webpage. The organization is still the author, and when it's also the publisher, its name appears only once. Link straight to the PDF.
Is a page by a hospital or health system cited the same way?
Yes. A page from a health system's patient library, with no byline, has the health system as its author, and the site name usually drops out because it matches. Watch for "Last reviewed" dates on those pages: they don't count, so a page with only a review date takes n.d.
