"I would like to open a account at Commerzbank"

[kavinda14]

Wie kann man das sagen?

Ist es: "Ich möchte ein Konto bei Commerzbank eröffnen"
Oder: "Ich möchte ein Konto bei Commerzbank einrichten"

[mlynarova]

'Ich möchte ein Konto bei der Commerzbank eröffnen.'

[drtiny]

I don't think it's necessary to specify the bank (you'll just go there).

Eröffnen is correct.

That entirely depends on the manner in which the sentence would be used. If they need to write it in a letter or say it to someone, specifying the bank isn't just preferable but necessary.

[drtiny]

To me, it sounded more like a request, but you're right pointing out other possible scenarios. In yours it can be a useful piece of information, I don't agree on the necessity of said precision :)

[jzsuzsi]

I'm not German, and I'm not sure, but I would pick "eröffnen" because einrichten is more like furnish, furnish a room with furniture.

How about simply öffnen?

[mizinamo]

No, öffnen sounds funny to me in connection with a bank acount.
