A PIN-kód nem helyes.

In Hungarian, the verb van (to be) is usually left out in the present tense, third person, when one thing is being identified or described.

So:

• A PIN-kód helyes. = The PIN code is correct.
• A PIN-kód nem helyes. = The PIN code is not correct.

This is completely normal Hungarian. English needs is, but Hungarian often does not in this kind of sentence.

A is the definite article, meaning the.

So:

• a / az = the

Hungarian has two forms of the:

• a before a consonant sound
• az before a vowel sound

Since PIN-kód begins with a consonant sound, Hungarian uses a:

• A PIN-kód

Because PIN-kód starts with the consonant sound p, Hungarian uses a, not az.

Compare:

• a könyv = the book
• az alma = the apple

So:

• a PIN-kód = correct

Hungarian often uses a hyphen when an abbreviation or acronym is combined with another word.

So:

• PIN
  • kód → PIN-kód

This is standard Hungarian spelling. The hyphen helps show that the first part is an abbreviation.

You will see similar patterns in other words too.

Helyes means correct, right, or proper depending on context.

In this sentence, it means:

• correct
• valid
• right

So A PIN-kód nem helyes means the PIN code is not correct, for example because the digits entered are wrong.

Nem is the normal Hungarian word for not, and it usually comes directly before the word or part of the sentence being negated.

Here it negates helyes:

• helyes = correct
• nem helyes = not correct

So the structure is very natural:

• A PIN-kód nem helyes.

Yes, it is possible.

• helyes = correct
• helytelen = incorrect

So these are similar:

• A PIN-kód nem helyes. = The PIN code is not correct.
• A PIN-kód helytelen. = The PIN code is incorrect.

The version with nem helyes often sounds a little more neutral and conversational. In real-life interfaces and spoken language, both can occur, but nem helyes is very common.

Yes, you could, and people would understand it.

• jó = good
• nem jó = not good / not right

So:

• A PIN-kód nem jó.

This is a bit more informal and less precise than nem helyes. For error messages, nem helyes often sounds slightly more standard or appropriate.

Hungarian word order is more flexible than English word order, but the basic sentence here is the most neutral one:

• A PIN-kód nem helyes.

This is the normal, unmarked way to say it.

Other word orders may be possible in special contexts for emphasis, but for a learner, this is the form to remember.

Yes. Hungarian uses PIN-kód as a standard everyday term, even though from a strict English logic point of view it is a bit redundant.

This kind of redundancy is common in many languages, including English itself, where people often say PIN number.

So in Hungarian, PIN-kód is just the normal established word.

In everyday Hungarian, it is commonly pronounced roughly like:

• pin-kód

The second part, kód, has a long ó, so it sounds longer than a short o.

Very roughly:

• PIN = like English pin
• kód = koawd with a long o

A simple learner-friendly approximation is:

• pin kohd

It is neutral and very natural.

You could see it:

• on an ATM screen
• on a phone
• in online banking
• in everyday speech

It is neither especially formal nor especially casual. It is just standard Hungarian.

Yes, depending on context, that is a very natural English translation.

Possible translations include:

• The PIN code is incorrect.
• The PIN code is not correct.
• The PIN code is invalid.

If this appears on a device or login screen, The PIN code is incorrect or invalid is often the best natural English rendering.
