Open almost any professionally issued press release and the body begins the same way: a place and a date, set before the first sentence — “AUSTIN, Texas — March 3, 2026 —” — and then the news. That short opening line is the dateline, and it is one of the oldest conventions in journalism. It is also one of the most frequently fumbled: wrong city, stale date, embargo instructions tangled into it, or the line missing altogether.

This guide explains the dateline in a press release completely: what it is and what it is not, the standard format and its common variations, how to choose the city and the date, whether it still matters when releases are published online, and the mistakes that make a release look careless before anyone has read the second line. If you want the full structure around it, our step-by-step guide on how to write a press release covers the whole document; this article is about its first line.

What a Dateline Is

A dateline is the short line of type that opens the body of a press release, giving the place the news comes from and the date it is issued. It sits at the start of the first paragraph — traditionally in capital letters, separated from the opening sentence by a dash — and the first paragraph’s text follows on the same line. The convention comes from newspaper and wire-service journalism, where the dateline told readers where a reporter was filing from and when. Press releases inherited it because releases are written to be usable as news copy: the closer a release matches the format journalists work in, the easier it is for them to use it.

Two facts, then: a place and a date. Everything the dateline does — orienting the reader, signalling freshness, locating the story — is done by those two facts and nothing else. That simplicity is worth keeping in mind, because most dateline errors come from loading the line with things that do not belong in it.

What a Dateline Is Not

Three neighbouring elements are routinely confused with the dateline. Keeping them separate is most of the skill.

Not the Publication Date

The date stamped on a web page by a content management system, or the publication date in a newsroom archive, is metadata: it records when that page or post went live. The dateline date is part of the release text itself and states when the announcement is made. The two usually coincide, but they can legitimately differ — a release written to a wire’s format keeps its dateline when it is republished, quoted or archived elsewhere, long after the page carrying it was posted. When you reissue or correct a release, it is the dateline you update, as discussed below.

Not the Embargo Line

An embargo is an instruction to journalists: do not publish before a stated time. It belongs at the very top of the release, above the headline, worded plainly — “Embargoed until 09:00, Tuesday 3 March” — where it cannot be missed. The dateline is not an instruction; it is information inside the story. Folding the embargo into the dateline, or using the dateline date to hint at it, buries the one line that absolutely must be seen first. On an embargoed release the dateline still carries the normal city and the release date; the embargo does its separate job at the top.

Not the Byline or the Header Line

A byline names the author of an article; press releases do not usually carry one, and the dateline is not a substitute for it. Likewise, the “FOR IMMEDIATE RELEASE” line that some releases place above the headline is header furniture, a distribution instruction from the print era — related in spirit to the dateline but a different line doing a different job. Releases have furniture at both ends: the dateline opens the body, and at the far end the boilerplate and the end marks close it, which our companion guide on how to end a press release explains.

The Standard Format

The standard dateline follows a fixed pattern: the city in capitals, the state, province or country where the style requires one, a comma, the date written out, and a dash before the text begins:

CITY, State — Month Day, Year — the release text follows.

Rendered as it actually appears: “CHICAGO, Ill. — March 3, 2026 — Hartley Foods today announced…”. The details that matter are consistency and completeness: the city is capitalised, the date is written in full rather than as numerals (“3/3/26” is ambiguous between countries and looks like a spreadsheet), and the dash marks clearly where the dateline ends and the sentence starts. Some house styles run the dateline into the first sentence in title case instead of capitals — acceptable if it is the house style and it is applied every time.

Style Variations You Will See

• Wire and AP style. The Associated Press tradition, which most wire services follow closely, includes the state for most cities but omits it for a short list of cities considered recognisable on their own — New York, Los Angeles, Chicago (in AP’s own list) and others stand alone. AP style also abbreviates most months in dates. This is the format journalists are most accustomed to, and the safest default.
• International style. Outside the United States, the country usually replaces the state or province: “LONDON —” needs nothing after it, while a less familiar city takes its country — “PUNE, India —”. Date order also flips in many countries’ house styles, from Month Day, Year to Day Month Year: “3 March 2026”. Neither is wrong; the audience decides.
• House styles. Individual companies and agencies vary the capitalisation (all-caps city versus title case), the dash (em dash, en dash, or a colon in some European formats), and whether the date sits in the dateline at all. A house style that differs from wire style is survivable; a company whose releases each use a different one is not.

Whichever variation you adopt, write it into the company’s style guide once and then stop deciding it per release.

Which City Goes in the Dateline

The rule underneath all the conventions is simple: the dateline city is where the news is happening. A factory opening is datelined from the factory’s city, a conference announcement from the conference city, a local partnership from the place it affects. The city is a factual claim about the story’s origin, and readers — especially local journalists — treat it as one.

Headquarters is the right answer when the news is corporate rather than local: executive appointments, results, company-wide policy. In those cases the announcement genuinely originates at HQ, and the HQ city is honest. Agencies issuing on a client’s behalf conventionally use the client’s city, not their own — the release is the client’s news, and an agency’s office location adds noise, though practices vary and the client’s preference governs.

The honesty rule follows directly: never use a dateline city the story is not actually from. A small company datelining from a capital city where it has no presence, to look bigger, is making a false statement in the first three words of its release — and it is exactly the kind of detail a local reporter checks. The same applies to virtual announcements: a launch conducted entirely online is usually datelined from the company’s base, which is truthful, rather than from wherever the servers or the webinar host happen to be. If a story genuinely spans several places, the dateline takes the primary one and the others are named in the body; a dateline can only hold one city.

Which Date Goes in the Dateline

The dateline date is the date the release is issued — the day it goes out to journalists and the wire, not the day it was drafted, approved or briefed. If a release is written on Monday for distribution on Thursday, Thursday’s date goes in the dateline. This sounds obvious and is still one of the most common production errors, because drafts carry their creation date forward through every revision unless someone is assigned to change it.

Two special cases. On an embargoed release, the dateline date is the date of release — the day the embargo lifts and the news becomes public — while the embargo instruction itself sits at the top, as described above. And when a release is updated or corrected and reissued, the reissue gets the new date, ideally with the change flagged (“Updated” in the header or a note in the text). A correction circulating with the original date makes it impossible for a reader to tell which version they are holding. Time zones are almost never part of the dateline; they belong in embargo instructions and event details, where precision about hours actually matters.

Datelines in the Digital Era

It is reasonable to ask whether the dateline still earns its place. Online, every page is automatically timestamped; a release read on a phone in another hemisphere was not, in any physical sense, filed from its dateline city. Some online-only announcements drop the dateline, and nothing terrible happens. So is it pure ceremony?

Mostly no — three practical reasons keep it alive. First, the distribution system still runs on it: wire services format releases with datelines, newsroom systems expect them, and journalists scanning a release read the dateline before the first sentence, looking for the two facts it carries. Second, orientation: for a reader who finds the release through search or syndication, stripped of its original page and timestamp, the dateline is the surviving evidence of where the story is from and when it was current — the metadata belongs to the page, the dateline travels with the text. Third, professionalism is cumulative: a release that gets the small conventions right is read as more trustworthy than one that gets them wrong, fairly or not. The honest verdict is that the dateline matters less as information than it did in the print era, and still matters as format — and since it costs one line, keeping it is the right default.

Worked Examples

Four opening lines, each correctly formatted for its situation. The companies are generic illustrations; the formats are the point.

• Standard US, state included: “AUSTIN, Texas — March 3, 2026 — Northbridge Robotics today opened its second manufacturing facility…” — a local story, datelined from where it happens.
• Recognisable city standing alone: “NEW YORK — March 3, 2026 —” — wire style omits the state for the cities on its standalone list.
• International, day-first date: “LONDON — 3 March 2026 —” — country unnecessary for a capital this familiar; the date follows the local convention.
• Less familiar city, country added: “ADELAIDE, Australia — March 3, 2026 —” — the country does the orienting work the state would do in a US dateline.

Note what none of them contains: no embargo wording, no “for immediate release”, no company slogan, no second city. One place, one date, then the news.

Common Mistakes

• The wrong — or borrowed — city. Datelining from HQ when the event is elsewhere, or from a prestigious city the story has no connection to. The first confuses readers; the second is a small falsehood that invites a big credibility problem.
• The stale date. A release drafted last week, or updated and reissued, still carrying its original date. Assign the dateline date to whoever sends the release, and check it last.
• Dateline and embargo tangled. “Embargoed” wording buried inside the dateline where a journalist scanning quickly can miss it. The embargo goes at the top, in its own line, every time.
• The missing dateline. Usually a formatting casualty of copying a release into an email or a web form. If the release will travel — and releases are built to travel — the dateline is what keeps its origin attached to it.
• Inconsistency across releases. State in one month, no state the next; capitals here, title case there; two date formats in a quarter. Readers may not consciously catalogue it, but newsrooms notice, and it reads as a communications team without a style guide.
• A dateline that contradicts the story. The release datelined from one city announces an event in another with no explanation — a launch “held in Denver” under a Chicago dateline. If the story’s geography needs a sentence of explanation, give it one in the body.

Datelines in Other Formats

The dateline follows news format wherever news format goes. Media advisories — the short who/what/when/where notices inviting journalists to an event — open with a dateline too, because the city is half the information an advisory carries: a local journalist decides whether to attend largely on where and when. Statements issued in a company’s name, such as responses to an incident, are conventionally datelined from where the company is responding, and the date does real work there, fixing the statement in the sequence of events. Pitch emails, by contrast, take no dateline: they are correspondence, and the email header already carries date and sender. Newsroom posts and blog versions of a release usually rely on the page’s own timestamp — but if the release text itself is pasted in, keep its dateline with it, for the travelling-with-the-text reason above.

FAQs

Is a dateline mandatory in a press release?

Not by law, and nobody rejects a release for lacking one — but it is a standard expectation of the format, and wire services and newsroom systems are built around it. Omitting it saves one line and costs you the convention journalists read first. Treat it as standard unless your channel genuinely has no use for it, such as a release published only on your own timestamped newsroom page.

Can the dateline city differ from our headquarters?

Yes — it often should. The dateline follows the news, not the org chart: events, openings, local partnerships and market launches are datelined from where they happen. Headquarters is the dateline for corporate news that originates there. The only hard rule is honesty: the city must be a place the story genuinely comes from.

What date goes on an embargoed release?

The date the news becomes public — the day the embargo lifts. The embargo instruction itself, with its exact time, goes at the top of the document, separate from the dateline. Journalists receiving the release early see the instruction; readers seeing the published release see a dateline that matches the day the story appeared.

Do online-only releases need a dateline?

They can survive without one, because the page supplies a timestamp — but releases rarely stay where they were published. They are copied into emails, databases, coverage and archives that strip the page furniture away. Keeping the dateline is cheap insurance that the release always carries its own where and when with it.

Conclusion

The dateline is two facts — a place and a date — in a fixed format, at the head of the story. Choose the city the news actually comes from, use the date the release actually goes out, keep the embargo and the header lines in their own places, and apply one style consistently. None of that is difficult, which is precisely why getting it wrong stands out: the dateline is the first line a professional reader sees, and it quietly reports how careful the sender is. Get it right and nobody notices — which, for the smallest line in the release, is exactly the job.
