Both spellings are correct. A requester, also spelled requestor, is a person or group that makes a request. Major dictionaries treat requester as the main spelling and requestor as an accepted variant.
If you write for a US audience, requester is the safer choice. Requestor is still common in legal forms, software systems, and payment standards. The most important rule is to pick one spelling and use it consistently.
Quick Answer
💡 Short version: Use requester in general writing. Use requestor when a form, system, or official document you are following already uses it.
| Spelling | Status | Best used for |
| Requester | Main dictionary spelling | Emails, articles, reports, everyday writing |
| Requestor | Accepted variant | Forms, technical fields, legal and payment terms |

What Does Requester Mean?
A requester is the person who asks for something. The thing requested can be information, a service, a document, a favor, or an action.
The word is a noun. It names the one who makes the request.
- Simple meaning: One who makes a request.
- Part of speech: Noun.
- Plural: Requesters (or requestors).
- Possessive: The requester’s form (or the requestor’s form).
Here are two natural examples:
- The requester must sign the form before we can send the records.
- Each requester receives a confirmation email within a day.
Why Are There Two Spellings?
English uses two common endings to name a person who does something. One is er, as in teacher and driver. The other is or, as in actor and editor.
The ending or often appears in words with Latin roots, and in many legal terms such as grantor and executor. That habit helps explain why requestor feels natural in legal and business settings.
Still, the base word request is a verb in English. Adding er to a verb is the most regular way to name the person doing the action. That is why requester is the main entry in dictionaries.
⚠️ Note: Neither spelling is a mistake. A spell checker may flag one of them, but that does not make it wrong.
Which One Should You Use?
Follow these simple steps.
- Check the document you are working in: If a form says “Requestor Name,” match it.
- Check your style guide: Many companies and agencies choose one spelling.
- If nothing is set, use requester: It matches the main dictionary entry.
- Stay consistent: Do not switch spellings within one document.
Is It Different in the UK, Canada, or Australia?
Many people search for regional versions. I could not find a reliable source showing a clear national split like the one between color and colour. Both spellings appear in all major English-speaking countries. For that reason, I do not recommend choosing based on region. Use the dictionary default and follow your organization’s style.
Requester vs Requestor vs Requestee
People often confuse these three words. The first two are spelling variants. The third has a different meaning.
| Word | Meaning | Example |
| Requester | The person who asks | The requester asked for a copy of the report. |
| Requestor | Same meaning, variant spelling | The requestor asked for a copy of the report. |
| Requestee | The person who is asked | The requestee approved the request. |
💡 Tip: The ending ee usually names the one who receives the action. Think employer and employee, or interviewer and interviewee. So the requestee is the one being asked.

How Requester and Requestor Are Used in Different Contexts
Both words appear in specific fields. The meaning stays the same. Only the setting changes.
Public Records and FOIA
In public records requests, the person asking for records is called the requester. Government guidance on the Freedom of Information Act commonly uses the requester spelling. If you are writing about FOIA, use that spelling unless you are quoting a form.
Service Desks and Tickets
In IT and customer support, a ticket requester is the person who opened the ticket. A service requester is someone asking for a service, such as a repair or a software installation. Either spelling may appear, depending on the software tool.
Payment Tokens
In digital payments, a token requestor is a business or app that asks for a secure token to replace a real card number. A token requestor ID is the code that identifies that business or app. Payment industry documents commonly use the requestor spelling here, so match it when you write about these systems.
Forms and Applications
A form field labeled requestor information asks for details about the person making the request. This usually includes a name, contact details, and sometimes a department. A requestor name field simply asks for that person’s name.
What Is a Co Requestor?
A co requestor is a second person who joins the first person in making a request. Both people share the request. This term mostly appears in business and legal forms rather than in everyday speech.
How to Pronounce Requester and Requestor
Both words sound exactly the same. The spelling changes, but the sound does not.
- Simple pronunciation: rih KWES ter
- IPA: /rɪˈkwɛstər/
- Stress: On the second syllable (reQUESter)
- Syllables: Three (re, ques, ter)
The ending is not stressed, so er and or blur into the same soft sound. That is one reason people mix them up in writing.
Where Does the Word Come From?
The word starts with the verb request. English took request from Old French. The word for the person who requests was then built in the usual English way, by adding a suffix to the verb.
The suffix could be er or or. Both are very old patterns for naming people who do things. Over time, dictionaries settled on requester as the main form and kept requestor as a variant.
Synonyms and Related Words
You can often replace requester with a more specific word. The right choice depends on the setting.
| Word | Meaning | How it differs |
| Applicant | Someone applying for a job, benefit, or place | Used for formal applications |
| Petitioner | Someone making a formal appeal | Used in legal or official contexts |
| Claimant | Someone who asserts a right or makes a claim | Used for insurance and legal claims |
| Asker | Someone who asks | Plain and informal |
| Inquirer | Someone who asks for information | Focused on questions, not actions |
⚠️ Common mistake: Do not treat these as perfect swaps. An applicant applies. A claimant claims. A requester simply asks.
