Requester vs. Requestor — What's the Difference?

Difference Between Requester and Requestor


Key Differences

"Requester" and "requestor" are two variations of the same word. Both words are nouns and describe an individual or entity that makes a request. While they share this meaning, they differ in their usage and regional popularity.
In the realms of American English, "requester" is the predominant form. Its consistent use across official documents, software applications, and general communications gives it an edge over "requestor". On the other hand, "requestor" is sometimes seen, particularly in older texts or in specific contexts.
Despite the distinction in preference, there's no inherent difference in meaning. A "requester" of information and a "requestor" of information are essentially the same. However, when drafting or communicating in professional settings in the US, it's advisable to stick to "requester" as it's more universally recognized and understood.
Yet, it's also important to be adaptive. Should you encounter "requestor" in any documentation, especially in older scripts or in contexts outside of the US, it's crucial to understand its equivalency to "requester". In essence, while "requester" may be the modern go-to, "requestor" still holds its ground in select contexts.
