Give your customers from Argentina the possibility of making or receiving immediate transfers.


The Uniform Virtual Key (CVU) is the digital account identifier in the banking system. It is a 22-digit number necessary for the account to receive and send transfers.

CVU Example: 0000002100092295498369

In addition to the CVU, the account has an associated alias that consists of a name between 6 and 20 alphanumeric characters that also identifies the account. The alias has the same functionality as the CVU, but it is usually more used since it is easier to remember.

Alias example:

By being connected to the local banking system, your customers will be able to make or receive transfers from or to an account from another bank entity. Transfers are immediate and can be made and received at any time of the day.

To send or receive a transfer, the account must have an associated Uniform Virtual Key (CVU).

Creating CVU and alias

The CVU and alias are automatically created when the account is created in Pomelo. Then, your customers can modify their alias, but not their CVU.

In case your customer wants to modify the alias, you can do it by calling Update alias.

You can obtain the data from any CVU or alias by making a query to our Get CVU/alias Information API.

Making transfers

These are the steps to make an outgoing transfer:

  1. Your customer enters the CBU, CVU or alias of the destination account.
  2. We validate that the account exists and return you its data and the data of the account holder.
  3. Your customer confirms the transfer and you call our Perform transfer API to execute it. Within the request, you must inform the transfer amount.
  4. We make the transfer and we will return you a response indicating the final status of the transaction.

Receiving transfers

Your customer can also receive transfers through their CVU or alias, as long as the status of their account allows it.

This transaction starts from an external entity and when your customers receive a transfer and their balance is updated, we will notify you via webhook.
