There are 22 banks in Latvia, however if you are anticipated to open the bank account by mail, you could consider just 5-6 of them. Your consideration depends on your needs and your balance. If you have above million USD on your balance — go with big banks. If you have some thousand turnover — you can choose: do you need big bank where you will be treated as everybody, or you need very special service, but can do without your favorite brand on your credit card or some other small extra. All Latvian banks working with non-resident customers have credit cards, ATM cards, Online (Internet) banking and other remote account management tools.
