Do I Need a Destination Tag for XRP?

No. Your XRP deposit address on BloxCash is generated for you alone, so the address by itself is enough to credit your balance. There is no destination tag to copy, and nothing to fill in beyond the address.

Tags exist for services that pool everyone’s deposits into one shared address and need an extra number to tell customers apart. Exchanges work that way; BloxCash does not.

Two notes:

• If you are sending from an exchange and its form asks for a tag, leave the field empty. If it refuses to send without one, any number will do: your deposit is credited by address alone, and the tag is ignored.
• Going the other way matters more: when you withdraw XRP to an exchange, that exchange usually does require its tag, so copy both the address and the tag from the exchange’s deposit page carefully.

The same goes for coins that use a memo field: deposits here need only the address.
