Is another way to receive a verification code, instead of a physical letter?

yes message partner support for alternative method.

Friendly reminder : we cannot help with account nor invoice/payout issues here, you must message Partner Support to open a case and then if urgent follow up with a phone call. see contact options below.

Simply report to BdC Partner Support , see below 3 methods. They will never see any post on the Partner Hub.

Message or Call BdC PartnerSupport 

1. In the extranet, go to the ‘Inbox’ tab.
2. Select ‘Booking.com messages’.
3. Right Pane - Click on ‘See Contact Options’. 
4. Choose Account
5. Now choose Other
6. Then at bottom , See all contact options, and click Message or Call
7. As there is no one number for all partners, the number for your nearest BdC Partner Support is then revealed.
