When you’re using DogPay to send payments or conduct financial transactions in Mexico—whether as an individual or a business—it’s crucial to understand the following codes and what they mean in context.

1. CLABE (Clave Bancaria Estandarizada)

What it is: The CLABE is an 18-digit standardized bank account number used across Mexico for domestic electronic funds transfers.

Structure breakdown:

• 3 digits – Bank code

• 3 digits – Branch or locality code

• 11 digits – Bank account identifier

• 1 digit – Control (checksum) digit to catch errors

This ensures that your DogPay‑initiated transfers reliably reach the correct beneficiary account—no mix‑ups or bounced payments.

2. RFC (Registro Federal de Contribuyentes)

What it is: The RFC is Mexico’s Federal Taxpayer Registry, a unique tax identification code mandated for anyone (individual or company) engaging in economic activity—like receiving or sending large payments via DogPay.

Format and use:

• Individuals: 13-character code combining name initials, birthdate, and a homoclave (verification set)

• Businesses: 12-character code derived from company name, incorporation date, and homoclave

DogPay may require your RFC when handling fund flows tied to taxation or when reporting transactions for regulatory purposes.

3. CURP (Clave Única de Registro de Población)

What it is: A nationwide identity code issued to every Mexican citizen and resident—much like a Social Security number in the U.S.

This 18-character alphanumeric string is built from:

• initials from names

• birthdate

• gender code

• birthplace code (state or “NE” if born abroad)

• internal consonants

• a unique differentiator and control digit

Why DogPay users need it: CURP is often required for account setup, identity verification, governmental compliance, or linking financial profiles within Mexico.

4. ABM (Asociación de Bancos de México)

What it is: The ABM (Mexican Bank Association), which, alongside Mexico’s central bank, defines standards like CLABE and assigns official bank codes.

Relevance to DogPay: Understanding which bank code corresponds to each institution—like BBVA, Santander, Banamex—helps DogPay route transfers correctly when you input the CLABE.

Practical Scenario Examples

• If you’re a freelancer in Mexico using DogPay to receive payments, provide your CLABE to clients, and your RFC to your accountant or for invoicing purposes.

• If you’re a resident opening DogPay—and need to verify your identity—your CURP will likely be requested.

• When sending funds to a Mexican account, DogPay relies on CLABE for accuracy—powered by standardized codes defined by the ABM.
