The arrival card asks for a visa number but my e-visa shows two numbers (Số and Mã). Which one do I use?

Use the Số number, which is the e-visa number printed as the visa's serial. The code next to Mã is the registration or lookup code from your application and is used to check your status on the government portal.

If you are unsure, compare the two against the top of your PDF. The visa serial is the one printed on the visa itself, and the registration code is the one you received by email when you applied.

If the form rejects the number, copy it again from the PDF without spaces or dashes, then check the issue and expiry dates against the visa. A one-character mistake is the most common reason the form will not accept the document.

You can look up your visa with the code on the government portal or on our track page if you applied with us. Our e-visa guide shows what each part of the visa means.
