Je vérifie l’IBAN du bénéficiaire.

Because je only shortens to j’ before a vowel sound or a silent h.

• je vérifie → vérifie starts with v, so no elision
• j’aime, j’habite → these start with a vowel sound, so je becomes j’

So Je vérifie is the correct form.

Vérifie is the 1st person singular present tense of vérifier.

So:

• je vérifie = I check / I am checking
• infinitive: vérifier = to check / to verify

This is a very common -er verb pattern:

• je vérifie
• tu vérifies
• il/elle vérifie
• nous vérifions
• vous vérifiez
• ils/elles vérifient

In French, the present tense often covers both the simple present and the present continuous in English.

So Je vérifie l’IBAN du bénéficiaire can mean:

• I check the beneficiary’s IBAN
• I am checking the beneficiary’s IBAN

French usually does not need a separate form for am checking. If needed, context makes it clear.

Because French normally shortens le or la to l’ before a vowel sound.

Since IBAN begins with the vowel sound i-, you say:

• l’IBAN

not:

• le IBAN
• la IBAN

This is called elision.

It is normally treated as masculine: un IBAN.

That matters because the full article is really le, which becomes l’ before a vowel:

• le IBAN → l’IBAN

So even though you only see l’, the gender is still masculine.

Because de + le contracts to du in French.

So:

• de le bénéficiaire → du bénéficiaire

This contraction is required in normal French.

Here, du bénéficiaire means:

• of the beneficiary
• or, more naturally in English, the beneficiary’s

So l’IBAN du bénéficiaire literally means the IBAN of the beneficiary.

French usually does not show possession with an apostrophe plus s.

Instead, it commonly uses:

• de = of
• or a contraction like du = of the

So:

• l’IBAN du bénéficiaire = the beneficiary’s IBAN
• literally: the IBAN of the beneficiary

This is a very common French structure.

In this context, bénéficiaire means the person who receives the money or transfer.

Depending on context, English might translate it as:

• beneficiary
• recipient
• payee

In banking language, beneficiary or payee is often the most natural choice.

There actually is an article before bénéficiaire—it is hidden inside du.

• du = de + le

So the sentence contains:

• l’IBAN = the IBAN
• du bénéficiaire = of the beneficiary

Both nouns are definite here.

It breaks down like this:

• Je = subject = I
• vérifie = verb = check / am checking
• l’IBAN du bénéficiaire = direct object = the beneficiary’s IBAN

Inside that object:

• l’IBAN = main noun
• du bénéficiaire = phrase that specifies whose IBAN it is

So the basic structure is:

Subject + Verb + Object

which is the same overall order as in English.

No, not in standard French for this meaning.

You need an article before bénéficiaire, so you say:

• du bénéficiaire = of the beneficiary

Without the article, de bénéficiaire sounds incomplete here.

So the correct phrase is:

• l’IBAN du bénéficiaire

Yes. In French, accents are part of correct spelling and can affect pronunciation.

Here you have:

• vérifie
• bénéficiaire

A learner should try to keep them, especially in writing. Even when meaning is still understandable without them, the correct written form uses the accents.

It sounds completely normal, especially in banking, administrative, or customer-service contexts.

• vérifier is a standard everyday verb
• IBAN and bénéficiaire are more specialized financial terms

So the sentence is natural and standard French, especially when talking about bank transfers or payment details.
