It was very fast, the communication was very simple but effective, I recommend it. When I need a COC document again, this is where I'll do it. Thank you.

Guys, don’t let them fool you. Once you pay and enter your VIN number, all they actually do is apply for the certificate directly from the dealer – which you could have done yourself free of charge. T... See more

SCAM! SCAM!

This site has fake reviews and it is a scam. Once you ordering a Audi COC they stop replying to emails. They said at the beginning the COC was requested, but nothing arrived. AVOID!

Dear,

Thank you for your comment.

321COC is a legitimate service provider offering official Certificates of Conformity issued directly by manufacturers or their authorized partners. Processing times depend entirely on the manufacturer, and customers are informed of this at the time of ordering.

We are unable to identify any order matching the situation described, and we note that very similar reviews have been posted under other profiles targeting other companies offering the same service. For this reason, we cannot verify the authenticity of this review.

Should this concern a genuine order, we invite the reviewer to contact us directly with an order reference so we can review the case and provide assistance.

We remain committed to transparency, professionalism, and customer satisfaction.

Kind regards,
321COC

all good, original COC

I was happy with the service. I received the COC even before the deadline. The whole process was very clear, I received all information via email so I didn’t need to contact their customer support. The COC received seems original real because it is printed on paper with a watermark so I will order from them in the future for sure.

Be aware

Be aware. I ordered one COC for Audi. Radio silence for two weeks, today I asked them again and they blocked me from WhatsApp.

It's extremely infuriating. Be careful.
