How to Buy Bitcoin in Mexico with SPEI

SPEI is the central bank rail that moves MXN between Mexican banks in seconds, and it is the cheapest way to fund a crypto purchase. A few exchanges accept it directly; the rest route MXN through P2P merchants. Cash options such as OXXO exist but cost more and settle slowly.

  • Use a direct SPEI deposit if the exchange lists it — cheapest and fastest.
  • Otherwise use P2P with a verified merchant and keep the chat inside the order.
  • Start with MXN 200–500 for the first order.

KYC checklist

  • INE or passport, all corners visible, no glare.
  • CURP or RFC where the exchange asks for tax data.
  • Selfie with liveness check in a well-lit room.
  • Proof of address (comprobante de domicilio) from the last 90 days if requested.
  • The SPEI account must be in your own name — third-party deposits are returned.

P2P safety checklist

  • Pay only the account shown on the order page. Anyone asking you to switch accounts is scamming you.
  • Never cancel an order after paying — cancelling removes platform arbitration protection.
  • Do not move the trade to WhatsApp or Telegram; keep every message and receipt inside the order.
  • A payment screenshot is not proof of arrival. Confirm the balance in your own bank or wallet app.
