The correct spelling is R-E-G-I-S-T-E-R-E-D

Registered is spelled with eight letters: R, E, G, I, S, T, E, R, E, D. The word comes from the verb "register," which means to record something officially or to sign up. When you add the past tense ending "-ed," you double the final "r" before adding the suffix, giving you "registered."

In graphic design, you will see this word most often in the phrase registered trademark — the legal term for a brand name or logo that a company has officially filed with a government office like the U.S. Patent and Trademark Office (USPTO). The symbol ® next to a brand name means it is registered.

Designers need to spell this correctly when they are writing about trademarks, creating documents that reference brand guidelines, or explaining licensing terms to clients. A misspelling looks careless and can confuse the legal meaning of what you are describing.

Key Takeaways

  • Registered is spelled R-E-G-I-S-T-E-R-E-D, with the final "r" doubled before adding "-ed."
  • In design work, "registered" usually refers to registered trademarks, which are officially filed with government trademark offices.
  • The ® symbol indicates a registered trademark, while ™ indicates an unregistered trademark claim.
  • Designers should spell this word correctly in client documents, brand guidelines, and any text that discusses intellectual property.
  • Misspelling "registered" in brand documents undermines credibility with lawyers, investors, and other stakeholders who review design work.

Why the spelling matters in design documents

When you are writing a brand style guide, a proposal, or any document that mentions a client's trademark, the spelling of "registered" signals that you understand the legal distinction. A registered trademark has stronger legal protection than an unregistered one, and the difference matters to the business owner.

If you write "registerd" or "regestered," it reads as a typo and undermines your credibility — especially in documents that will be shared with lawyers, investors, or other stakeholders. Brand guidelines in particular are legal documents, and accuracy in every word counts.

Clients notice spelling errors in materials they will present to their own teams or to the public. A careless misspelling of "registered" in a brand guide or trademark notice suggests you did not carefully review the work, which raises questions about other details you may have overlooked.

The difference between ® and ™ symbols

The ® symbol means the trademark is registered with a government office. You can only use this symbol if the mark is actually registered. Using ® on an unregistered mark is illegal in most countries.

The ™ symbol means the owner claims the mark as a trademark but has not filed for official registration. You can use ™ without government approval, but it offers less legal protection. As a designer, you need to know which symbol your client is may have access to to use, and that knowledge starts with understanding what "registered" actually means.

When you place these symbols in a design, you are making a legal statement on behalf of your client. Getting the symbol wrong — or misspelling the word that explains it — can create liability for both you and the business owner.

Common misspellings and how to avoid them

The most common mistakes are "registerd" (missing the second "e"), "regestered" (swapping the "i" and "e"), and "registred" (dropping the second "e" entirely). These happen because the word has three "e"s total, and it is straightforward to lose track of where they go.

A straightforward way to remember: the root word is "register" (R-E-G-I-S-T-E-R), and you add "-ed" to make the past tense. That gives you R-E-G-I-S-T-E-R-E-D. If you are unsure, type it into your spell-checker or use a dictionary before you send any client-facing document.

Another memory trick: think of the word "register" as having a double "r" at the end (R-E-G-I-S-T-E-R). When you add "-ed," that second "r" stays, and then you add the "e" and "d" from the suffix. So you get R-E-G-I-S-T-E-R + E-D = R-E-G-I-S-T-E-R-E-D.

When you will encounter this word in design work

You will write "registered" when you are documenting a client's intellectual property, explaining trademark rights in a proposal, or creating a brand guidelines document. You might also see it in contracts, licensing agreements, or when discussing which marks a company owns.

If you are designing for a large brand, their legal team will have already decided whether to use the ® symbol, and your job is to place it correctly and spell any accompanying text accurately. If you are working with a small business owner who is unsure about registration, you can explain the difference — but the spelling itself should never be in question.

Even in informal design conversations — emails to clients, Slack messages to your team, notes in a design brief — spelling "registered" correctly sets a professional standard and prevents confusion about what you are discussing.

How to check your work before sending

Most design software includes a spell-checker: use it. In Adobe InDesign, Illustrator, and Photoshop, you can run spell-check from the Edit menu. In web design tools like Figma, a browser spell-checker will catch obvious errors as you type.

For client documents created in Word, Google Docs, or similar programs, spell-check is automatic. But do not rely on it alone — read the document yourself, especially any text that mentions trademarks or legal terms. Your eye will catch errors that a spell-checker might miss if the misspelling is close to a real word.

Frequently Asked Questions

Is it "registered" or "registerd"?

It is "registered" with eight letters: R-E-G-I-S-T-E-R-E-D. The word doubles the final "r" from "register" before adding the "-ed" ending. "Registerd" is a misspelling.

Can I use the ® symbol if a trademark is not registered?

No. The ® symbol is only legal to use on trademarks that are officially registered with a government office like the USPTO. Using it on an unregistered mark is trademark misuse and can result in legal penalties. Use ™ instead if the mark is not registered.

What is the difference between a registered and unregistered trademark?

A registered trademark has been officially filed with a government office and receives stronger legal protection, including the right to sue for infringement in federal court. An unregistered trademark is a mark the owner uses and claims, but it has weaker legal standing and is harder to defend against copying.

Do I need to include the ® symbol every time I write a brand name?

No. Most style guides say to use the ® symbol the first time you mention a registered trademark in a document, then use the brand name without the symbol afterward. Check the client's brand guidelines — they will specify their preference.

What should I do if I am not sure whether a client's trademark is registered?

Ask the client directly. You can also search the USPTO database online at uspto.gov to see if a mark is registered, but the client should confirm which symbol they want you to use. Never guess about trademark status in a design document.
