In the English language, it is important to understand the proper use of the perfect tenses. For example, when we try to talk about an action that occurred for some time and was ongoing, is it “has been” or “had been”? “Has been” is only used with third-person nouns or pronouns to indicate an action that started in the past and either finished in the recent past present perfect or continued for a period present perfect continuous. “Had been” is used in the past perfect tense to emphasize a completed action that began in the past, and the past perfect continuous emphasizes the duration. This article will cover the details surrounding when we should use “has been” or “had been.” We’ll provide a few examples of constructing sentences in the present perfect, past perfect, and their continuous tenses. The Difference Between Has or Had “Has” and “had” are forms of the verb “have,” which as a transitive verb means to possess or hold. As an auxiliary verb, we use “has,” “had,” or “have” with past participles to form the present perfect, past perfect, or future perfect tense source. We use “have” with first- and second-person pronouns, like “I” and “you.” “Has” is the present tense form that goes with third-person singular nouns, like “he,” “she,” and “it.” Meanwhile, “had” is the past tense form as well as the past participle of “have,” and it works with all of the pronouns. PerspectivePronounsPresent TensePast TenseFirst PersonI, weHaveHadSecond PersonYou, theyHaveHadThird PersonHe, she, itHasHad For more on using the auxiliary verbs “have” and “had,” make sure you take a look at the article “Have Run or Had Run When to Use the Proper Past Tense.” “Has been” and “had been” are perfect tense forms that combine the auxiliary verbs “has” or “had” with the past participle of “be,” which is “been” source. If you have “been” somewhere, that means you have gone to that place or been in that circumstance. “Has been” is in the present perfect or present perfect continuous tense, while “had been” is in the past perfect or past perfect continuous tense. Meanwhile, we can use “have been” for the present perfect or future perfect tenses source. What Is the Perfect Tense? The perfect tense indicates an action that someone or something has completed perfected. In the English language, we usually use three primary verb tenses to indicate an action according to the time frame in which it occurred. These are the past something that has happened, the present something that is still happening, and the future tense something that will happen, respectively. Grammarians further categorize each of these — past, present, and future tenses — into simple, progressive, perfect, and perfect progressive tenses. Thus, for example, “Has been” or “Had been” belong to the perfect tense and perfect progressive/continuous tense. If we do not follow “has been” or “have been” with another participle, they are in the present perfect tense, while “had been” is in the past perfect tense. By adding another participle after the past participle “been,” we form the present perfect and past perfect continuous tenses. Thus, “has been” is in the present perfect continuous or progressive tense, while “had been” is the past perfect continuous or progressive tense. Present PerfectHas + been + locationHe has been to the Perfect ContinuousHas + been + present participleI have been running for three PerfectHad + been + locationHe had been to the Perfect ContinuousHad + been + present participleI had been running for three hours. Has Been Meaning “Has been” means that someone or something was in the act of doing something or in a particular circumstance or location. We use “has been” to indicate something that someone started in the past and finished perfected in the recent past or is still ongoing. When it is complete, we call it the “present perfect” because the results are visible in the present, even though the action has ceased source. We can also use “has been” to refer to repeated or recurring events that continued until the present. The main difference between the present perfect tense and the present perfect continuous is that the present perfect tense focuses on a completed action. In contrast, the present perfect continuous tense emphasizes the continuation of an action source. While the present perfect continuous can also refer to a completed action, there is still a greater degree of continuity with the present. The present perfect tenses involve using “have been” for first- and second-person singular and plural pronouns, while we use “has been” for third-person nouns or pronouns. “Has Been” or “Have Been” Examples Present Perfect The present perfect tense uses the auxiliary verb “has” or “have” with a past participle. The construction for the present perfect tense includes an object after the participle that is either the object of the verb or the object of the preposition. I have called my has written three has called for another have watched the movie. We can also use “has been” or “have been” in the present perfect tense when we do not follow them with an -ing verb. This indicates that someone has gone to a particular location. They have been to have been in a meeting for an hour. Examples Present Perfect Continuous In contrast, we can form a simple sentence in the present perfect continuous using the following construction Subject + the auxiliary verb “has” or “have” + the past participle “been” + the present participle. It has been raining for two have been reading this book. In these examples, the action is either still going on or has ceased in the recent past. We often use “has been” to show that someone or something — he, she, or it — started an action in the past that is still continuing. She has been teaching in this school all her has been washing the car since this has been around for a year. In the last example, the present perfect continuous verb tense indicates that Eric arrived about a year ago, but it implies that he is still there. We can do the same for “have been,” only we refer to ourselves or the addressees. First-person singular I have been reading The Ring for a month plural We have been visiting for a singular You have been running that company for 15 plural They have been studying for the biology exam the whole day. We can also refer to recent past activities where we can still see the effects of the activity. It’s been been has been decorating. Notice how we can use the contracted forms as well. “It’s” means “it has,” while “I’ve” is the contracted form of “I have.” Examples Negative and Interrogative Statements To form a negative statement in the present perfect tense, we simply insert the adverb “not” between the auxiliary verb and the main verb. He has not called his has not been to has not written three books. Tommy has not called for another meetingI have not watched the movie Similarly, we can form a negative statement in the present perfect continuous by inserting “not” between the auxiliary verb and the past participle “been.” It has not been raining for two have not been in a meeting for an have not been reading this book. Also, we can form an interrogative sentence by changing the order of the subject and the auxiliary verb. Present perfect Has he written three books?Has Tommy called for another meeting?Have I watched the movie? Present perfect continuous Has it been raining for two hours?Have they been meeting for an hour?Have you been reading this book? Had Been Meaning Unlike “has been” or “have been,” we use “had been” in all past perfect tenses irrespective of the person or plurality of the noun or pronoun. The main difference between the past perfect and the past perfect continuous is that we use the past perfect continuous to describe how long something went on before another important event happened in the past. In contrast, the past perfect emphasizes the completion of an action before another event in the past. Had Been Examples Past Perfect The past perfect is a tense that we use to talk about experiences and actions that were completed at some point in the past. For example, how would you explain a story to your friends where the events happened in the past? This is where the past perfect tense comes in handy. Consider the following scenario You go out for your morning walk, and when you return, you find out someone left a gift for you with a message that “Joey was here.” If you were to describe this series of events to someone else, you might say, “I returned home and saw that Joey had left me a gift.” We use the past tense auxiliary verb “had” with a past participle to form the past perfect. Our team had won the had lost the teacher had punished the boy. Examples Past Perfect Continuous We use “had been” to define an action that began in the past, continued for some time, then ended in the past. In other words, its origin, continuation, and termination are all entirely in the past. We construct the past perfect continuous tense as follows Subject + had been + present participle. I had been teaching there for a few had been painting the had been raining for had been their employee for seven had been talking for over an hour before their friend arrived. Examples Negative and Interrogative Statements Just like the present perfect, we can form a negative statement in the past perfect by inserting the adverb “not” between the auxiliary verb and the main verb. Past perfect I had not cleaned the had not implemented the original had not met her husband. Past perfect continuous I had not been teaching there for had not been implementing the plan as they were supposed sun had not been shining for days. Unlike the present perfect, we don’t generally form an interrogative sentence when we reverse the order of the auxiliary verb and the subject. Instead, we generally form a dependent clause. Past perfect Had I not cleaned the paint, I would have been in serious they not planned ahead, the trip could have taken twice as I not met her husband, I might have believed the accusations. Past perfect continuous Had I not been teaching there for a few months, I wouldn’t they not been painting the walls, I would have it not been raining for hours, we could have returned to the fields. This article was written for For more on the past and present perfect, you may want to check out “Can I Use Present Perfect and Past Perfect in the Same Sentence?” Final Thoughts We use “Has been” in either the present perfect or the present perfect continuous tense. We use “has been” for third-person nouns and pronouns, while we use “have been” for first- and second-person singular or plural nouns. On the other hand, we use “had been” for the past perfect tenses regardless of the noun or pronoun. The continuous tenses all indicate something that began in the past and continued for some time. The present perfect continuous indicates that the action either ended recently or is still ongoing. In contrast, the past perfect continuous indicates an action that continued for a time before ending in the past.

tl;dr Both are grammatical, but it depends on what you intend to say. In this case it depends if the time of the request in relation to the utterance is pertinent or not. Firstly, there are three grammatical categories bound up in your example sentence. Tense - When in time the event occurred Aspect - Whether the event is complete perfect aspect or not unmarked form Voice - Whether the event is described from the perspective of the agent active voice or the patient passive voice So, let's take a sentence such as your team requests the items. The event being denoted is request, it requires an agent, your team and a patient, the items. As the sentence is active, the agent is encoded as the subject and goes before the verb phrase, and the patient is encoded as the object and is encoded within a verb phrase as a complement of the verb. The tense is present and it is unmarked for aspect. You can do various things with this sentence. You can change the tense to past by request -> requested, and you can change the aspect to perfect by requests -> have requested. Note that this is still technically present tense or non-past depending on your theory of tense in English, and what's important here is that the event, the requesting, is complete, rather than its relationship in time with the time of the utterance. You can then change the tense of this by have requested -> had requested. In this case, the event is complete, and took place at some time in the past as compared with the utterance. The context of this might be I came by yesterday, and your team had requested the items already. Another thing you can do is change the voice so as to focus on the patient rather than the agent. This is a more complex syntactic transformation. You take the patient, the items and make it the subject, and you take the agent, your team and you either delete it or you put it into a prepositional phrase headed by by, and you change the verb from [verb] to [be + verb-en], so, from request to be requested. Then, the auxiliary verb be is put into the right tense. So for present, you get the items are requested by your team. Next step is combine past tense with the passive, producing were requested. Alternatively, you can combine the passive with perfect aspect, producing have been requested. Lastly, you put all three together and you get had been requested. Thus, the difference between have been requested and had been requested is simply one of tense. The former is present and the latter is past. You woulduse the former where the time of the request itself is not pertinent, but instead the fact that the requesting is complete. You would use the latter if the time of the request is in fact pertinent, such as in the context I came by yesterday with the request form, but the items had already been requested by your team, or somesuch. Just a note, I don't mean to imply that past perfect passives are 'transformed' from unmarked or default structures by movement. But it's a helpful way of thinking about it. I'm also skipping a lot in here, such as that perfect aspect is encoded by [have + verb-en], but if I get any more complicated I'm-a hafta pull out some tree diagrams!
