Who it suits

  • Mexican households who want a free account with money earning interest every day
  • People who move most of their spending through SPEI transfers rather than card payments
  • Savers who want to start investing small, at a minimum investment of MXN 6

Who should look elsewhere

  • Anyone based outside Mexico, since MX is where the account is held
  • People who want a phone line, as support runs on chat and help centre
  • Savers chasing a fixed term, as the rate is variable and access terms carry no fixed terms

Safety of your money

DINN is not a standalone bank. The account is held with Banco Actinver, and the business sits under Comision Nacional Bancaria y de Valores (CNBV) in Mexico. That means the money is in a bank balance rather than an investment fund, and interest is credited to the available balance every day. There is no fixed term to be trapped in, and the account carries a monthly fee of MXN 0. Deposits and withdrawals work through SPEI transfers, the method most used locally.

Who runs it

DINN started in 2017 and is based in Mexico, with the banking side of the operation sitting with Banco Actinver. Support runs on chat and help centre, which means quick answers go through in app chat while written guidance lives in the help centre. There is no phone line listed, so a lost card is handled in the app or the help centre rather than by telephone. The account is aimed at personal users, not business account holders.

Frequently asked questions

What does it cost to hold a DINN account?+

The account carries a monthly fee of MXN 0 and an annual fee of MXN 0, so there is nothing to pay for keeping it open. The minimum deposit is MXN 0. Investing is separate, and that side carries a management fee of 0%.

Does DINN pay interest on the balance?+

Yes. Interest is credited daily to the available balance, and the rate is variable rather than locked in. That suits someone who wants their cash to earn something while still being reachable, since the access terms carry no fixed terms at all.

Who regulates DINN?+

The business is supervised by Comision Nacional Bancaria y de Valores (CNBV) in Mexico. The account itself is held with Banco Actinver, so the money sits with a banking entity rather than a savings institution under a separate name.

What card do I get with DINN?+

It is a debit card that runs on the visa network, so it works wherever those cards are accepted. There is also a virtual card available for spending online without handing over the physical card.

How do I move money in and out?+

Transfers run over SPEI, and the account includes unlimited SPEI transfers around the clock. There is no fixed term and no set schedule, so money moves in and out as needed rather than on a notice basis.

How much do I need to start investing through DINN?+

The minimum investment is MXN 6, which is small enough to begin with. Portfolios are built around etf holdings, and the management fee on the investing side is 0%.

How do I get help if something goes wrong?+

Support runs on chat and help centre, so a chat channel handles quick questions and a help centre holds written guidance. There is no phone channel listed, so a blocked card is dealt with in the app or through the help centre.

Where is DINN available?+

DINN is based in Mexico and its transfers are built on SPEI, the local system. The account is aimed at personal users rather than business account holders, so it is a domestic offer rather than a multi country one.
